Summer smog is also known as photochemical smog. In congested areas, slums and rural areas burning of firewood and biomass results in lot of smoke. Outlook Summer can bring more than just sunshine and swimming opportunities. Catalytic converter Proper maintenance of automobiles along with use of lead-free petrol or diesel can reduce the pollutants they emit.
Use of disinfectants, fumigants, etc. Ethylene is not but Ethylene oxide is a carcinogen. These precautions can help protect you when ozone levels are high: Particulate matter PM and ozone O3 pollution are major causes of concern in the community.
In the presence of oxygen, carbon monoxide burns with a blue flame, producing carbon dioxide. But at high temperatures they produce various oxides of nitrogen.
In support of this observation, the World Health Organization estimates that every year, 2. All the buses of Delhi were converted to run on CNG by the end of They are produced naturally by lightening. Baghouse filtration system is the most common one and is made of cotton or synthetic fibres for low temperatures or glass cloth fabrics for higher temperature up to C.
This article has been cited by other articles in PMC. The particles get trapped as they travel from supporting gaseous medium across the interface to the liquid scrubbing medium. The rest of the country was expected to meet Euro-III emission norm by It is also a major cause of ocean acidification because it dissolves in water to form carbonic acid.
Effects on Environment Carbon dioxide is an important greenhouse gas. It is now known that prolonged inhalation of asbestos fibers can cause serious and fatal illnesses including lung cancer, mesothelioma, and asbestosis a type of pneumoconiosis.
Prevention and Control of air Pollution Indoor Air Pollution Poor ventilation due to faulty design of buildings leads to pollution of the confined space.
Benzene increases the risk of cancer and other illnesses. Radon It is a gas that is emitted naturally by the soil. In hospitals, pathogens present in waste remain in the air in the form of spores. Devices like filters, electrostatic precipitators, inertial collectors, scrubbers, gravel bed filters or dry scrubbers are described below: Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater.
Explained in a separate post on Ozone Depletion The Montreal Protocol on Substances that Deplete the Ozone Layer a protocol to the Vienna Convention for the Protection of the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances including CFCs which are responsible for ozone depletion.
The EPA notes that the majority of people only need to be concerned about smog when ozone exposure reaches high levels. NOx emissions cause global cooling through the formation of -OH radicals that destroy methane molecules, countering the effect of greenhouse gases.
Filters Filters remove particulate matter from the gas stream. Addition of lead in petrol has been banned to prevent emission of lead particles with the vehicular emission. Since the late s, the use of CFCs has been heavily regulated because of their destructive effects on the ozone layer.
Indoor pollution due to decay of exposed kitchen waste can be reduced by covering the waste properly. Paints, carpets, furniture, etc. They are produced mainly in internal combustion engines and coal burning power plants.
These exposure levels correspond to red and purple colors on the index, respectively. Due to modern houses having poor ventilation, it is confined inside the house and causes lung cancers. Motor vehicles equipped with catalytic converter should use unleaded petrol because lead in the petrol inactivates the catalyst.
According to an estimate, a substantial fall in CO2 and SO2 level has been found in Delhi between and It is now known that prolonged inhalation of asbestos fibers can cause serious and fatal illnesses including lung cancer, mesothelioma, and asbestosis a type of pneumoconiosis. The roasting of sulfide ores such as pyrite, sphalerite, and cinnabar mercury sulfide.
Noise is undesired high level of sound. It also weakens the functioning of certain nerves. Addition of lead in petrol has been banned to prevent emission of lead particles with the vehicular emission. Effects on Environment Carbon dioxide is an important greenhouse gas.The Clear Thing About China’s Smog.

The Clean Air Act authorizes the U.S. Environmental Protection Agency. The effects of air pollution are diverse and numerous.
Air pollution can have serious consequences for the health of human beings, and also severely affects natural ecosystems. think about air pollution, they usually think about smog, acid rain, CFC's, and other forms of outdoor air pollution. Pollutants can be in form of solid.
