When inhaled these particles can cause many diseases like lung cancer, tuberculosis etc. Though Chinas economy is developing but the rate of growth could be faster if pollutants level could be lowered. As the health of people is affected, productivity is also affected, so in the long run, economy declines Ekstrom.
Hence, policies should be imposed to keep the GDP growth in flow and prevent health damages. Several policies can be imposed The effective ways are discussed below: 7 Green taxes such as output tax policy and fuel tax policy can be established.
Inefficient or improperly vented heaters are particularly dangerous. The usual approach is to sample the open, or ambient, air and test it for the presence of specified pollutants. The amount of each pollutant is counted in parts per million or, in some cases, milligrams or micrograms per cubic meter. To learn how much pollution is coming from specific sources, measurements are also taken at industrial smokestacks and automobile tailpipes.
Pollution is controlled in two ways: with end-of-the-pipe devices that capture pollutants already created, and by limiting the quantity of pollutants produced in the first place. End-of-the-pipe devices include catalytic converters in automobiles and various kinds of filters and scrubbers in industrial plants. In a catalytic converter, exhaust gases pass over small beads coated with metals that promote reactions changing harmful substances into less harmful ones.
When end-of-the-pipe devices first began to be used, they dramatically reduced pollution at a relatively low cost. As air pollution standards become stricter, it becomes more and more expensive to further clean the air. In order to lower pollution overall, industrial polluters are sometimes allowed to make cooperative deals.
For instance, a power company may fulfill its pollution control requirements by investing in pollution control at another plant or factory, where more effective pollution control can be accomplished at a lower cost.
End-of-the-pipe controls, however sophisticated, can only do so much. As pollution efforts evolve, keeping the air clean will depend much more on preventing pollution than on curing it. Gasoline, for instance, has been reformulated several times to achieve cleaner burning.
Various manufacturing processes have been redesigned so that less waste is produced. Car manufacturers are experimenting with automobiles that run on electricity or on cleaner-burning fuels. Buildings are being designed to take advantage of sun in winter and shade and breezes in summer to reduce the need for artificial heating and cooling, which are usually powered by the burning of fossil fuels.
The choices people make in their daily lives can have a significant impact on the state of the air. Using public transportation instead of driving, for instance, reduces pollution by limiting the number of pollution-emitting automobiles on the road. During periods of particularly intense smog, pollution control authorities often urge people to avoid trips by car. The types are extremely harmful to the environment and could result in serious damage.
There are many causes of air pollution and there are many to blame. The first type of air pollution is smog. The word smog came from a newspaper article almost 50 years ago.
This indicates that although precipitation in general may promote wet deposition of particulates, the daily rainfall itself does not significantly dictate the magnitude of PM and therefore it may not be a significant factor for seasonal variation.
High PM concentrations have been found to be associated with winds coming from northern and northwestern directions during the dry season, suggesting that the brick kiln clusters situated in the northern periphery of the city are contributing to the degraded air quality by emitting particulate matter.
Trends in air quality over the past decade show large seasonal variations in both PM2. Smog is a form of air pollution created by the photochemical reaction with sunlight and the chemicals in the air, and than this deadly mixture is released into the atmosphere. The Serious Problem of Air Pollution in Saudi Arabia and the Solutions to the Environmental Issue Air pollution could be defined as any substance that may harm the environment, and the living beings. Where asbestos has been used in insulation, it can be removed or sealed behind sheathes so that it won t be shredded and get into the air.
Smog in cities is expected to increase as the number of cars and miles driven continues to rise.
If you are studying environmental sciences, you will most likely have to address the problem of air pollution in your writing.
The worst such accident occurred in in Bhopal, India, when methyl isocyanate released from an American-owned factory during a thermal inversion caused at least deaths. The Air Pollution Problem Air pollution has continued to increase over recent decades, particularly in Vietnam. Less developed nations, hoping for rapid economic growth, are less enthusiastic about pollution controls. Where asbestos has been used in insulation, it can be removed or sealed behind sheathes so that it won t be shredded and get into the air. On the global scale, pollution control standards are the result of complex negotiations among nations. The number of rainy days in a month during the wet period has been found to have strong negative correlation with average monthly PM concentrations.
Several policies can be imposed As pollution efforts evolve, keeping the air clean will depend much more on preventing pollution than on curing it.
Ozone in the lower atmosphere is a poison it damages vegetation, kills trees, irritates lung tissues, and attacks rubber. Smog spoils views and makes outdoor activity unpleasant.
Another study by 6 Organic for Economic Cooperation and Development predicted that urban air pollution will be cause about 3.
