Air pollution
Air pollution refers to toxic substances in the atmosphere generated by human and natural activities that can harm humans and the environment. There are two main types of air pollution: primary pollutants that enter directly from sources like vehicle exhaust and biomass burning, and secondary pollutants that are formed through chemical reactions, including ozone and photochemical smog. Major sources include the combustion of fossil fuels for energy and transportation, industrial processes, agriculture, and natural phenomena like volcanic eruptions. Air pollution damages plant leaves, slows plant growth, and makes plants more susceptible to insects.
Smog
Smog is air pollution that occurs when smoke and fog combine, giving it a yellowish or blackish color. It forms when pollutants from sources like vehicle emissions, industrial activities, and burning of crops and forests react with sunlight. Smog can cause respiratory and cardiovascular health issues in humans. It also damages crops and contributes to acid rain. A major smog event in 1952 London is believed to have caused over 12,000 deaths. Pakistan experiences smog due to agricultural fires within the country as well as dust storms carrying pollutants from neighboring countries like India. The government has taken some actions to monitor and reduce smog but more efforts are still needed.
sulfur dioxide ~ atienza
Sulfur dioxide is a toxic gas that is released by volcanoes and industrial processes like burning coal and oil. It can cause a lung disease called bronchiolitis obliterans when inhaled, leading to scarring and narrowing of the small airways over time. Diagnosis involves lung function tests showing obstruction. The disease has no cure and may require a lung transplant for severe cases. Treatment includes steroids.
Air pollution (NCERT Class 8) Ln: Air and Water Pollution
Air pollution is caused by excessive amounts of unwanted gases in the atmosphere from various sources such as vehicles, factories, power plants, and natural sources. The main types of air pollution include smog, acid rain, and greenhouse gases that cause global warming. The effects of air pollution are serious and include health impacts from smog, environmental damage from acid rain, and long-term consequences of global warming such as rising sea levels. One example is the Taj Mahal, where air pollution is discoloring and corroding the white marble monument. Reducing activities that produce air pollution can help prevent further damage.
Unit 5
The document discusses various topics related to air pollution including its definitions, sources, effects, and control measures. It defines air pollution as the presence of man-made substances in the atmosphere that can negatively impact human health and welfare. The two main sources of air pollution are natural sources like volcanoes and forests fires, and man-made sources such as industry, automobiles, and agriculture. Some of the key effects discussed include impacts on human health like respiratory illnesses, as well as environmental effects such as acid rain, global warming, and ozone layer depletion. The document also examines the health impacts of different air pollutants and various methods that can be used to control air pollution.
Acid Rain
Acid rain is caused by sulfur dioxide and nitrogen oxides released through the burning of fossil fuels and other industrial processes. These gases dissolve in water droplets in the atmosphere to form acids that fall to Earth as rain, snow, or fog. Acid rain damages trees, aquatic life in lakes and rivers, and infrastructure like buildings. While some sulfur dioxide occurs naturally, human activities like burning coal for electricity have significantly increased levels. Solutions involve reducing emissions through technologies that capture pollutants and using renewable energy and public transportation to decrease fossil fuel consumption. Individual actions like conserving energy and driving less can also help address acid rain.
Photochemical smog
Photochemical smog is a type of air pollution formed when sunlight interacts with nitrogen oxides and volatile organic compounds in the atmosphere. Nitrogen oxides come primarily from vehicle and truck exhaust while volatile organic compounds are emitted from products like paints, pesticides, and glues. This chemical reaction forms secondary pollutants like peroxyacetyl nitrate which can cause respiratory issues. Mexico City has high levels of photochemical smog due to vehicle emissions and geographic factors trapping pollution. Reducing vehicle use, industrial emissions, and VOC-emitting products can help lower smog levels and protect public health. The Great Smog of 1952 in London showed the deadly potential of severe smog, causing thousands of premature deaths.
Great smog of london1
The Great Smog of 1952 in London was a severe air pollution event lasting from December 5-9, 1952. Cold weather and temperature inversions trapped coal and industrial emissions in the lower atmosphere, creating thick smog that reduced visibility and brought transportation to a standstill. The smog caused over 12,000 deaths from respiratory illnesses and diseases, with 4000 deaths directly attributed to the smog period. The event increased awareness of air pollution issues and led to the Clean Air Act of 1956 aimed at reducing coal burning and industrial emissions.
Smog ppt
Smog is a combination of smoke and fog formed when pollutants from sources like automobiles, factories, and the burning of coal react with sunlight and moisture in the air. There are two main types of smog:
Industrial smog, like the 1952 London Smog, forms when coal smoke and sulfur dioxide combine with fog. It can be extremely toxic. Photochemical smog forms when nitrogen oxides and volatile organic compounds from fossil fuel combustion react with sunlight to produce secondary pollutants. Conditions like sunlight, temperatures over 18 degrees Celsius, and the presence of nitrogen oxides and volatile organic compounds are needed for photochemical smog formation. The reactions produce ozone and other toxic chemicals that can harm human

Air pollution is the introduction of chemicals, particles or biological materials into the atmosphere that can harm humans, other living things, or the environment. There are different types of air pollution including smog, acid rain, the greenhouse effect, and depletion of the ozone layer. Indoor air pollution from activities like smoking, cooking and building materials can be more dangerous than outdoor sources of air pollution. Acid rain forms when air pollutants combine with water droplets and can seriously damage the environment by acidifying lakes and streams and damaging trees and structures. The release of pollutants like CFCs into the atmosphere also contributes to the formation of holes in the ozone layer.

Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
ENVIRONMENT~ Renewable Energy Sources and their future prospects.
This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.
Recycling and Disposal on SWM Raymond Einyu pptx
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

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.

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.

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.

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.

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.

air pollution
- 3. Air pollution is the most dangerous form of pollution. The cause is that we cannot control the air that we inhale. Air pollution can be defined as the presence of gasses such as oxides of carbon, sulphur and nitrogen in the air.
- 5. Outdoor air pollution Outdoor air is often referred to as ambient air. The common sources of outdoor air pollution are emissions caused by combustion processes from motor vehicles, solid fuel burning and industry. Other pollution sources include smoke from bushfires, windblown dust, and biogenic emissions from vegetation (pollen and mould spores)
- 6. Indoor Air Pollution Indoor air pollution is caused by burning solid fuel sources – such as firewood, crop waste, and dung – for cooking and heating. The burning of such fuels, particularly in poor households, results in air pollution that leads to respiratory diseases which can result in premature death. The WHO calls indoor air pollution “the world’s largest single environmental health risk.
- 7. Acid Rain Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
- 8. Acid rain has been shown to have adverse impacts on forests, freshwaters, and soils, killing microbes, insects and aquatic life-forms, causing paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health.
