The Earth formed about 4.6 billion years ago from a disc-shaped cloud of gas and dust that gave rise to the Sun. Gravity pulled this material together, forming asteroids and small planets. For many years, Earth was healthy and beautiful until humanity began polluting the air, water, and land through industry, factories, and ignoring the effects of global warming. The major impacts of pollution include environmental degradation, threats to human health like respiratory and skin issues, increased global warming through greenhouse gas emissions, and depletion of the ozone layer.

Introduction to Earth
Earth is composed of four main layers - crust, mantle, outer core, and inner core. The crust is the outermost layer and is made up of either continental or oceanic crust. Below the crust is the mantle, which is divided into lithosphere, asthenosphere, upper mantle, and lower mantle. The outer core is a liquid layer made of nickel and iron that generates Earth's magnetic field. The inner core is made of solid iron deep within Earth. Overall, Earth's composition is approximately 34.6% iron, 29.5% oxygen, and 15.2% silicon.
Land Pollution
Land pollution is caused by waste in liquid or solid form from uncontrolled garbage disposal, sewage, and toxic and nuclear waste. It results in changes to soil color, fertility, and structure. Deforestation can also cause land pollution as the absence of tree roots makes the ground loose and prone to erosion. Soil contamination leads to diseases spreading through pests and damage to soil quality and plant growth. Environmental education and awareness campaigns can help address the problem by teaching people about protecting the environment.
Deforestation: Causes, Effects and Solutions
A presentation about the state of the world's forests, the main causes behind deforestation, and what we can do about it.
Global warming
The document discusses the difference between global warming and the greenhouse effect. Global warming refers to a rise in the earth's surface temperature, while the greenhouse effect is the process by which heat is trapped in the lower atmosphere by greenhouse gases. It then lists the major human-caused greenhouse gases and their sources, and notes that concentrations of these gases have increased significantly since the industrial revolution due to human activities like burning fossil fuels. The effects of this climate change are described as threats to health, water resources, polar regions, forests and more.
Deforestation
Deforestation involves clearing forests and converting the land to non-forest uses like agriculture. The main causes of deforestation are clearing land for housing and agriculture as well as logging trees for wood. This results in problems like soil erosion, climate change, and economic impacts. Solutions include implementing anti-deforestation policies, reforestation efforts, increasing recycling, using renewable energy instead of wood, and individual efforts to reduce consumption that drives deforestation.
Our planet EARTH
Earth formed about 4.5 billion years ago and is the only known planet that supports life. It has three main layers - a crust, mantle, and core. The crust ranges from 5-70 km deep and has both continental and oceanic parts. Below the crust is the thickest layer, the mantle, which extends to a depth of 2,890 km and is composed of silicate rocks. The innermost layer is the core, with a solid inner core of iron and nickel around 1,220 km wide and a liquid outer core that creates Earth's magnetic field.
deforestation
Deforestation is the removal of forests to make room for human development. It has increased due to population growth, urbanization, and industrialization. Deforestation leads to soil erosion, flooding, loss of wildlife, increased carbon dioxide in the atmosphere, and other environmental issues. Pakistan has one of the highest deforestation rates in Asia due to unsustainable logging and lack of enforcement of forestry laws. Reforestation efforts and use of alternative energy are needed to address deforestation.
Human Impact On The Environment
Human activities like population growth, industrialization, and burning fossil fuels increase carbon dioxide levels and pollution which damage the environment. Acid rain forms from sulphates and nitrates released by burning fossil fuels, acidifying lakes and killing wildlife. Deforestation reduces habitats and biodiversity while pesticides and herbicides have unintended harmful consequences, accumulating in ecosystems. Ozone depletion was directly caused by CFCs from aerosols destroying the ozone layer. Water pollution from oil and gasoline spills contaminates drinking water. The Exxon Valdez spill demonstrated these dangers as global warming increases due to rising greenhouse gases.

Essential resource of Life- WATER
This presentation talks about the Water Uses, Water Forms and Distribution, Availability, Fresh Water Shortage, Water Use Problems and Conflicts Increase Water Supply, Floods and Drought
It talks about the shortage of water all across the globe. So people should use it effectively without unnecessary wastage.
Deforestation
Deforestation involves the removal of forests to clear land for human development like agriculture and settlement. It occurs mainly due to increasing population and food demands, cultivation of land, overgrazing, fuel wood collection, timber extraction, and mining. Deforestation leads to negative environmental impacts such as soil erosion, disruption of the water cycle, loss of biodiversity, increased flooding, and climate change by releasing stored carbon. While Sri Lanka had extensive deforestation, it has implemented successful conservation measures and reduced its deforestation rates. Prevention efforts include planting trees, reducing waste, sustainable farming and harvesting, and increasing environmental awareness.
Tundra Ecosystem
The document discusses the tundra ecosystem. Tundra regions are treeless and found in the Arctic and high mountains. They are snow-covered for most of the year until summer. The fauna of tundra have thick fur and fat layers to survive the harsh climate, and include polar bears, snow rabbits, penguins, and bison. Flora is limited to shrubs, sedges, and mosses due to the permanently frozen soil. The average temperature is below 0°C, sometimes dropping as low as -40°C, and snow covers the ground for about 8 months each year. Global warming is dramatically changing the Arctic tundra and stressing its animals.

Climatic prediction till 2050
Climate is defined as average weather patterns over large portions of the Earth's surface over several years, whereas weather describes short term events. Climate change has natural causes like El Niño and plate tectonics, as well as human-caused factors including greenhouse gases from activities that release methane and CFCs. Global warming is expected to increase average global temperatures by 2-11.5°F by 2100 depending on future emissions levels, and increase sea levels, ocean acidification, and frequency of extreme weather events like flooding and drought. Low-lying coastal areas face inundation, and coral reefs are threatened by warmer oceans and acidification.
The Earth- A Very Basic Intro
The document provides a basic introduction to the Earth by discussing three key facts:
1) The Earth is the third planet from the Sun and is located in the solar system within the Milky Way galaxy.
2) Unlike a simple "rock," the Earth has an atmosphere, is over 70% covered in water, and has a molten interior, allowing life to exist.
3) Two factors that enable life on Earth are its rotation on an axis, which causes day/night cycles and seasons, and its orbit around the Sun, regulating temperatures.
Green House Effect
The greenhouse effect is when the temperature rises due to increased concentrations of carbon dioxide and other gases in the atmosphere that trap infrared radiation. It is caused by factors like the development of industry, burning of fossil fuels and forests, methane and CFC emissions, and automotive pollution. The greenhouse effect leads to unpredictable consequences such as flooding from melting glaciers that can displace people and damage infrastructure, shifting climate zones, disruption of ecosystems, more extreme weather, and reduced access to drinking water resources.
Soil Pollution
Soil pollution occurs when soil quality degrades due to contamination from natural or human sources. Common causes of soil pollution include industrial waste, urban waste, agricultural practices, and chemical/metallic pollutants. Pollutants such as heavy metals, pesticides, radioactive materials, and biological agents can enter the soil. Pollution transport processes that spread contaminants through soil include convection, diffusion, and dispersion. Mathematical models can simulate how different pollutants move through soil over time.
The amazon forest
The Amazon rainforest spans several countries in South America and contains the greatest biodiversity on Earth. It experiences a hot, humid climate year-round between 22-34°C due to its proximity to the equator. The Amazon River, born in the Andes Mountains, is the largest river in the world by volume and flows through the forest before emptying into the Atlantic Ocean. Over 20 million people from diverse indigenous tribes and cultures call the Amazon rainforest home. However, illegal logging has led to the deforestation of over 700,000 square kilometers of forest in Brazil alone in the past few decades.
The Amazon Rainforest
There are three major rainforests in the world: the Amazon, Congo, and Indonesia rainforests. The Amazon is the largest rainforest containing about 390 billion trees. Rainforests are full of beautiful and exotic animals and provide 50% of the world's food and 3/4 of clean water. Indigenous people of the Amazon live in houses made of leaves and straw, with fathers farming/hunting and mothers gardening/cooking, while children learn about plants and animals through play. Threats to the rainforest include deforestation for wood and paper, but conservation efforts like providing technology to report illegal logging are helping to protect these vital ecosystems.
Vulnerabilities of forests and forest dependent people
This document discusses the vulnerability of forest-dependent people and forests to climate change. It notes that over 1 billion people depend on forests for their livelihoods, while 1 billion hectares of land are under agroforestry worldwide. Climate change poses direct risks like increased temperatures and wildfires, and indirect risks through impacts on species and ecosystems. Potential transition issues from policies like REDD+ could negatively impact land and tree rights of indigenous groups. The document argues that comprehensive vulnerability assessments are needed using qualitative and quantitative methods to understand all vulnerabilities, include stakeholders, and identify good practices to address risks to forests and forest-dependent communities from climate change.
Global Water Crisis
Global water crisis is a serious issue affecting many regions of the world. Over 1/3 of the global population lacks access to clean drinking water. Lack of access to sanitation is linked to poverty and disproportionately impacts developing countries. Rapid population growth and development are straining water resources in many places through overuse, pollution, and depletion of sources. Improving access to clean water and sanitation worldwide is critical for public health, but achieving universal access remains a challenge.

Unit 6. The hydrosphere
The document discusses the hydrosphere and the water cycle. It defines the hydrosphere as all water on Earth's surface, including oceans (97% of which is salt water), lakes, rivers, groundwater, glaciers, ice caps, and clouds. It describes the three stages of the water cycle: evaporation and transpiration of water into the atmosphere, condensation of water vapor into clouds, and precipitation of water back to the surface through rain, snow, or hail. It also lists some properties of water and ways to conserve water resources.
Atmospheric Pollution
This is a PPT on Atmospheric Pollution. Here it decribes the 3 main types of Atmospheric Pollution: 1.Acid Rain, 2.Ozone Depletion, 3.Green House Effect.
3071 ppt -_natural_resources
The natural resources of Earth include air, water, soil, minerals and living organisms. Air is a mixture of gases that living organisms and combustion processes rely on. It also helps regulate Earth's climate. Water cycles through evaporation, condensation and precipitation in a continuous process. Soil is formed through weathering and supports plant life. These natural resources interact in biogeochemical cycles and sustain life on Earth. However, human activities like burning fossil fuels, industrial pollution and deforestation threaten these natural systems.
Water scarcity
This document provides information about environmental change and water scarcity. It discusses how only 3% of the world's water is freshwater, and this freshwater is distributed unevenly. It then covers several causes of water scarcity like climate change, population growth, and pollution. Various impacts of water scarcity are explained such as lack of access to drinking water, hunger, disease spread, and conflict over water resources. Solutions to water scarcity discussed include recycling water, improving farming practices, and supporting clean water initiatives. The document also contains country-specific information about water scarcity in India.
Ate urban climatology
Urban climates differ from rural climates due to factors like increased surface area from buildings absorbing heat, lack of vegetation and evapotranspiration, and additional heat from human activities. This can lead to urban heat islands where temperatures are warmer in cities. While some effects are negative like increased heat stress, others are positive like reduced energy demands. Urban climatologists first systematically studied these effects in the 19th century, and interest has grown with increasing urbanization globally. Mitigation strategies aim to reduce heat absorption and increase shading and evaporation to minimize urban warming.
Unit 12. human impact in ecosystems
This document discusses human impact on ecosystems and the environment. It notes that in nature, water, energy, and biomass cycles continuously recycle materials, but human activities like overexploitation of land and pollution have disrupted these natural cycles. Some key human impacts discussed are climate change, desertification and drought caused by overgrazing and deforestation, and loss of biodiversity. The document emphasizes the importance of reducing waste through recycling, which has benefits like preserving resources, reducing pollution, and saving energy.
water a precious resource for all
Global freshwater resources are under increasing pressure due to population growth, changing consumption patterns, and climate change. Most of Earth's water is saltwater, while only 2.7% is freshwater, with over two-thirds locked in icecaps and glaciers. Freshwater scarcity is a growing problem, exacerbated by overuse, pollution, and competing demands from agriculture, industry, and domestic use. Many regions will face serious shortages within 20 years if consumption patterns and management do not change.
Our home the earth solar system
The document discusses key facts about the solar system and the Earth's movement. It notes that the solar system consists of the Sun and 8 planets, with Pluto no longer being classified as a planet. It explains that the Earth is the third planet from the Sun and is the only planet that can sustain life, due to the presence of water, air, food and temperature (WAFT). The document also describes how the Earth rotates on its axis daily and revolves around the Sun yearly, resulting in day/night and the seasons.

Chapter 18 – air pollution and global changes
This document discusses various types of air pollution and their local and global effects. It describes how local pollution from activities like burning fossil fuels can cause issues worldwide through mechanisms like acid rain, ozone depletion, and global warming. Five major types of outdoor air pollutants are discussed - particulates, oxides, photochemical smog, hydrocarbons, and CFCs. The document also notes how air pollution affects human health, other organisms, and causes global problems through acid deposition, ozone layer thinning, and climate change due to increased greenhouse gases.
SEC23 GEOG Chapt10 Global Warming
Global warming and ozone depletion are caused by human activities that release greenhouse gases and CFCs into the atmosphere. This has led to rising global temperatures, melting ice caps, more extreme weather, and a growing ozone hole. Consequences include severe droughts, flooding, impacts on plants/animals/people from increased UV radiation and rising sea levels. International agreements aim to reduce emissions through measures like the Montreal Protocol and Kyoto Protocol, while countries also promote renewable energy and energy efficiency.

It explains that acid rain is caused by sulfur dioxide and nitrogen oxide emissions from burning fossil fuels reacting with water and falling as rain, snow, or dry deposition. This acidic precipitation harms aquatic environments, forests, and architecture. It also outlines the causes of ozone depletion including chlorofluorocarbons reacting with UV light and damaging the ozone layer, and effects such as increased UV exposure. The document then explains the greenhouse effect and evidence that increasing greenhouse gases from human activities are causing global warming and its impacts like sea level rise and more extreme heat waves.
What is pollution.pptx
- Pollution is the introduction of harmful materials, called pollutants, into the environment from both natural and human sources. Pollutants damage air, water, and land.
- The three major types of pollution are air pollution from vehicles, industry, and other sources; water pollution from chemical runoff, oil spills, sewage, and trash; and land pollution from mining, pesticides, fertilizers, and garbage.
- Pollution has negative impacts on both human and environmental health, contributing to issues like acid rain, global warming, waterborne diseases, and the degradation of habitats. Addressing pollution requires international cooperation and effective policies around waste disposal, emissions standards, and sustainable practices.

Unit iii notes social issues 1
Global warming is caused by an increase in greenhouse gases like carbon dioxide and methane that are trapping heat in the atmosphere. This is leading the planet to warm at a dangerous rate, with the average global temperature already 1°C higher than 1900 levels. The major cause of increased greenhouse gases is human activities like burning fossil fuels and deforestation. If emissions are not reduced, the global temperature could increase by 1-3°C by the middle of the century, causing serious environmental effects.

Global warming
Haven’t we had of this term before? Certainly we have encountered matters to do with global warming without our knowledge and for the case where an individual understands, then neglect is a norm. Global warming refers to the continued slight increase in the average temperatures of the earth which will lead to adverse effects including change in climate in this planet (Wear & Spencer, 165).
Human beings take part in global warming. Many activities we engage in end up emitting gases which are responsible for warming with or without our knowledge. This make up the green house gases. When we burn fossil fuels, drive our cars, operate our factory engines or in the process of producing electricity we release these gases. Carbon dioxide normally referred to as carbon (IV) oxide is the major gas that is responsible for global warming. Agriculture too is responsible for release of other supportive gases such as methane, ruminant animals in most cases will lead to release of methane gas. Fertilisers release nitrous oxide which is also in forefront in warming. Gases which are commonly used for refrigeration and industrial processes are also responsible for global warming.
Greenhouse gases have different ability in trapping heat (Houghton, 370). Many greenhouse gases have a higher heat trapping capability than carbon (IV) but since there concentrations are much lower and in some instances is negligible, then we need to focus in this carbon dioxide. For instance, methane has heat trapping capability that is twenty times more than carbon (IV) oxide gas. Nitrous oxide gas has a capability that is three hundred times more than carbon dioxide. However, carbon (IV) oxide is the leading in warming due to its high concentration in the atmosphere.
Understanding the earth’s atmosphere and its layers which are key to getting much in global warming is of essence. The earth has five layers in its atmosphere. These layers are troposphere, stratosphere, mesosphere, thermosphere and exosphere. The troposphere is the lower atmospheric layer in which we breathe. The middle atmosphere is made up of two layers namely stratosphere and mesosphere. The upper atmosphere consists of two layers again namely thermosphere and exosphere.
It is essential to understand what ozone is and later how it gets depleted as a result of this emissions. Basically, a molecule of oxygen is made up of two atoms of oxygen. The radiation of the sun breaks up some of the molecular oxygen apart in the stratosphere region. When one atom of oxygen collides with a molecule of oxygen, they fuse together. This compound consisting of three atoms of oxygen make up the ozone. Several of these compounds form the ozone layer. Ultraviolet (UV) are harmful rays from the sun. The ozone layer is responsible for bouncing back of these ultraviolet rays so that it does not reach the earth’s surface (Philander, 99). Stratospher.

The document provides an overview of air pollution, including natural and human-caused sources of pollution, conventional and unconventional pollutants, effects of indoor and outdoor air pollution, and efforts to control air pollution through legislation. Key topics covered include the major conventional pollutants regulated by the Clean Air Act like sulfur dioxide, nitrogen oxides, and particulate matter; unconventional pollutants like noise and light pollution; and international agreements like the Montreal Protocol to regulate pollutants that deplete stratospheric ozone.
Chapt16 lecture
The document provides an overview of air pollution, including natural and human-caused sources, conventional pollutants such as sulfur dioxide and nitrogen oxides, indoor and outdoor effects on health, and international efforts to regulate pollution through agreements like the Montreal Protocol. Key topics covered include the various types of primary and secondary pollutants, criteria pollutants defined by the Clean Air Act, long-range transport of pollutants globally, and the formation of the ozone hole from CFC emissions.
Air Pollution
This document discusses air pollution and its causes, effects, and potential solutions. It defines air pollution as a mixture of solid particles and gases in the air. The major causes of air pollution include the burning of fossil fuels for energy and transportation, industrial activities, agricultural activities, and vehicle emissions. The effects of air pollution include respiratory and heart problems, global warming, acid rain, impacts on wildlife, and depletion of the ozone layer. Proposed solutions include using public transportation, better household practices, conserving energy, reducing and recycling waste, developing clean energy sources, and using energy-efficient devices.
Pollution
Man has polluted the lithosphere, hydrosphere, and atmosphere through interference with natural processes and use of biological and physical resources. The document defines key terms like biosphere, ecosystem, atmosphere, and different types of pollution like primary and secondary pollutants. It discusses several types of environmental challenges caused by pollution, including greenhouse effect, ozone depletion, acid rain, smog, and their impacts on climate change, increased UV radiation, soil and plant damage. The conclusion emphasizes that while a certain environment is essential for human survival, industrialization has also increased environmental hazards like air, water, and noise pollution, causing health problems.
Global warming
Global warming is caused by greenhouse gases trapping heat from the sun in the atmosphere. It leads to rising sea levels and temperatures which damage agriculture and increase risks like droughts and wildfires. Actions like reducing fossil fuel use, planting trees, and shifting from coal to natural gas can help control global warming. Acid rain is caused by sulfur and nitrogen emissions reacting with water and falling to earth, and harms ecosystems. Nuclear accidents release large amounts of energy and radiation into the environment, as seen in disasters like Chernobyl. Innovative solutions are needed to address global warming and its serious impacts on humans, animals and plants.
Done
Global warming is caused by greenhouse gases like carbon dioxide and methane trapping heat in the atmosphere. This is called the greenhouse effect. While the greenhouse effect makes Earth habitable, the additional heat trapped by human emissions is causing problems. Temperatures are rising faster than ever before in human history due to increased CO2 from the burning of fossil fuels. This is harming ecosystems, raising sea levels, and jeopardizing human health and safety. Efforts to reduce emissions through alternatives to fossil fuels and carbon sequestration are needed to slow global warming.
Environmental pollution chapter 1
The document discusses various types of pollution including air, water, land, noise, and radiation pollution. It provides details on air pollution, including causes such as natural factors and human activities. Various air pollutants are defined including primary and secondary pollutants. Sources and effects of air pollution are described along with methods to control air pollution. Greenhouse effect, global warming, acid rain, ozone layer depletion, and water pollution are also summarized.
Environmental polluttion
This document is a cross curricular project submitted by Group 3 of Class 10 at Navodaya Vidyalaya on the topic of environmental pollution for the 2013-14 academic session. It was guided by several teachers and contains an introduction, types of pollution like air, light, littering, noise, water, soil and thermal pollution. It provides details on each type including causes, effects and methods to control pollution. The project was certified by the school principal.
Global warming
Global warming is caused by both natural and man-made factors that increase greenhouse gases and trap heat in the atmosphere. This leads to rising sea levels and temperatures that threaten coastal areas and species. Man-made causes are primarily from burning fossil fuels and releasing methane, while natural causes include volcanic eruptions and tundra emissions. Effects are already occurring like sea level rise and species endangerment, and future predictions include more extreme weather and temperature increases that exceed plant and animal adaptation. Preventing global warming requires reducing emissions through alternative energy, forestation, and energy efficiency.
environmental pollution
Environmental pollution occurs when harmful substances contaminate the environment. There are three main types of pollution: air, water, and soil pollution. Air pollution involves the release of chemicals and particulate matter into the atmosphere from sources such as vehicle exhaust and industrial emissions. Water pollution is when pollutants are discharged into bodies of water without proper treatment. Soil pollution involves the presence of harmful chemicals in the ground from activities like mining, pesticide use, and landfill waste. If left unchecked, environmental pollution can have serious negative effects on both the environment and human health.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Our earth our home
- 2. How the Earth was formed ?? The Earth is thought to have been formed about 4.6 billion years ago by collisions in the giant disc-shaped cloud of material that also formed the Sun. Gravity slowly gathered this gas and dust together into clumps that became asteroids and small early planets called planetesimals.
- 11. Our Earth was healthy and beautifull for many, many years, until the mankind decided that they know better what the Planet needs
- 12. Many people don't want to hear our Earth crying. They torture Her, they don’t respect Her, they kill Her.
- 13. We pollute the air, the water, the land ... This is the way we kill our Mother-Nature our Earth.
- 17. Because of Human Activities
- 20. Due to the global warming the earth is heating is up rapidly
- 22. 1. Environment Degradation : Environment is the first casualty for increase in pollution weather in air or water. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth .Water pollution may lead to death of several wildlife species. 2. Human Health : The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be causes by air pollution. Water pollution occurs due to contamination of water and may pose skin related problems including skin irritations and rashes. Similarly, Noise pollution leads to hearing loss, stress and sleep disturbance.
- 23. 3. Global Warming : The emission of greenhouse gases particularly CO2 is leading to global warming. Pollution in direct or indirect way which lead to increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas. 4. Ozone Layer Depletion: Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs), were released into the atmosphere which contributed to the depletion of ozone layer. 5. Infertile Land : Due to constant use of insecticides and pesticides, the soil may become infertile. Plants may not be able to grow properly. Various forms of chemicals produced from industrial waste is released into the flowing water which also affects the quality of soil.
- 36. What will u do if a robber breaks into your house ???? We would obviously catch that thief and hand him over to the police . We humans are the thieves in the earth . We take all the resources of our home without thinking about the future . So stop pollution :
