Pollution harms the environment and causes instability. There are four main types of pollution: air, land, water, and noise. Land pollution occurs when humans throw garbage on land, making it infertile. Plants that grow in infertile soil can become poisonous. When animals or humans eat poisonous plants, the poison enters their systems. Land pollution is caused by domestic waste, industrial waste, agricultural waste, and other sources. It leads to issues like less fertile land and habitat destruction. Water pollution pollutes water sources and can cause diseases in humans and animals. It stems from garbage, oil spills, factory chemicals, and sewage. It impacts marine life and food chains. Air pollution is very harmful as living things
environmental harmful effects
Pollution occurs when harmful or excessive materials are added to the environment, making it unfit for life. There are various types of pollution including air, water, soil, noise, and light pollution. Air pollution is caused by the release of pollutants like carbon monoxide, sulfur dioxide, nitrogen oxides and particulate matter from sources such as vehicles, power plants, and industries. Water pollution occurs when harmful substances are discharged into rivers, lakes, and oceans, affecting water quality and organisms. Soil pollution degrades soil quality through erosion, excessive fertilizer and chemical use, acid rain, and industrial wastes. Strong regulations and public awareness are needed to control different types of pollution and protect the environment.

Since we need oxygen to live, carbon monoxide pollution can be harmful to anyone, but it is most harmful for people with already low oxygen levels. Nitrogen oxides are another type of air pollutant, also from emissions from cars, trucks, buses, power plants, and off-road equipment.
AIR POLLUTION.pptx
Air pollution is introduced into the atmosphere and can harm humans, other living organisms, and the environment. There are two main types of air pollution: indoor and outdoor. Outdoor pollution includes smog, acid rain, the greenhouse effect, and depletion of the ozone layer. Indoor pollution is more dangerous than outdoor pollution. Air pollution has several negative effects like acidification of lakes and streams, damage to trees and forests, and accelerated decay of materials. It is caused by various sources such as vehicle emissions, industrial operations, and the burning of fossil fuels. Reducing pollution requires changes like using public transport, adopting renewable energy sources, and minimizing emissions.
air pollution
Air pollution occurs when harmful substances like gases, dust, fumes or smoke are introduced into the atmosphere. There are two types of pollutants: primary, which are directly emitted, and secondary, which form from chemical reactions between primary pollutants. Major causes of air pollution include emissions from industries, burning fossil fuels for transportation, and household/farming chemicals. Effects of air pollution include acidification, eutrophication, ground-level ozone formation, and particulate matter in the air. Control measures involve reducing emissions through planting trees, using cleaner fuels, mass transportation, and separating industrial and residential areas.
air pollution.pptx
Air pollution occurs when harmful gases, dust, or other particles are introduced into the atmosphere, making the air dirty and potentially damaging to humans, animals, and plants. It can be caused by both natural phenomena like volcanic eruptions as well as human activities such as burning fossil fuels for energy and transportation. Major air pollutants include carbon monoxide, nitrogen oxides, particulate matter, and ground-level ozone. Air pollution has wide-ranging negative health effects and can also damage the environment through acid rain and eutrophication. Both governmental regulations and individual actions are needed to monitor air quality and implement solutions to reduce pollution.
Ppt on pollution
Pollution refers to the contamination of the natural environment such as air, water, and land by harmful substances added through human activities. Common pollutants include carbon monoxide, sulfur and nitrogen oxides, dust, smoke, sewage, and chemicals from manufacturing and fossil fuel combustion. Air pollution is caused primarily by vehicle emissions, power generation, and chemical production. Water pollution results from sewage, industrial activities like manufacturing, agriculture, and urban runoff. To reduce pollution, we should practice the 3Rs of reduce, reuse and recycle; use vehicles less; create public awareness; and enforce anti-pollution laws.
Air pollutants
Major air pollutants come from a variety of sources and can negatively impact both the environment and human health. This document identifies and describes common pollutants like ozone, carbon monoxide, nitrogen dioxide, particulate matter, sulfur dioxide, toxic chemicals and greenhouse gases. Their sources include vehicle emissions, power plants, industrial facilities, and natural phenomena. The health effects of air pollutants range from respiratory illnesses to cancer, while environmental effects include acid rain, global warming and damage to ecosystems.
Pollution
Pollution is defined as the introduction of contaminants into the natural environment that cause adverse changes. There are different types of pollution including air, water, land, and noise pollution. Air pollution involves solid particles and gases in the air from sources like car emissions, factory chemicals, and smoke. Water pollution results from contamination of bodies of water from human activities. Land pollution stems from dumping garbage and waste on land. Noise pollution refers to the propagation of noise from sources such as machines, transportation, and propagation systems.
Environmental Pollution
Environmental pollution is one of the greatest problems facing the world today and is increasing each year. There are five main types of pollution: air, water, soil, noise, and light. Air pollution is the most harmful, caused by smoke from vehicles, factories, and burning materials. It is linked to health issues like lung cancer and breathing problems as well as damage to plants and animals. Water pollution from industrial and household waste has harmed marine life. Noise pollution comes largely from vehicles and includes sounds from planes, cars, trucks, horns, and industry. Soil pollution results from acid rain, chemicals, and contaminated water and damages crop growth. Light pollution interferes with astronomy and includes over-illumination and light trespass

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.

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.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

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.

Pollution
- 3. pollution is when something is added to the environment that is harmful or poisonous to living things. Smoke or dust in the air is a type of pollution as it is bad for the lungs when we breath in. Sewage in drinking water is another type of pollution, as it can make people ill because it contains germs and viruses
- 4. Here are some ways from which air pollution occurs Air pollution is caused by poisonous gases, sulphur dioxide, nitrogen dioxide, carbon monoxide and very small particulates. It is also caused by the smoke and harmful gases released by the fires that make vehicles and factories go. Use of coal, wood and kerosene as fuels for fire also causes air pollution.
- 6. Water pollution is the presence of harmful materials in water, such as sewage, dissolved metals, waste from farms, factories and crude oil spilled from oil tankers. The three main substances that pollute water are nitrates from fertilizers, sewage and detergents.
- 8. Noise pollution (also known as sound pollution) is noise which is harmful to humans and animals. This includes the sound of vehicles, loud speakers, etc. Noise pollution can cause ear problems or even permanent deafness, especially to older people
- 10. Soil pollution (also known as land pollution) is when man-made chemicals, such as hydrocarbons, heavy metals, solvents, get into the soil. These chemicals come from industrial activities and from bad waste disposal. Soil pollution may cause health risks. The chemicals can produce harmful vapors, or they can contaminate water supplies underneath the polluted soil.
