Easy air pollution essay
Growing awareness of problems such as air pollution and global warming is slowly forcing a shift to cleaner technologies, but the world remains firmly locked in its old, polluting ways. By far the biggest culprit today is traffic, though power plants and factories continue to make an important contribution.
They are highly efficient, often approaching The equipment used for this purpose may be of different kind , viz. Tropospheric ozone may damage lung tissues of animals.
Air pollution caused from natural sources can be more severe and longer lasting than air pollution from human activities. Laws and regulations By itself, technology is as likely to harm the environment as to help it. Pollution can also be classified by what makes it. This makes the air that we breathe indoors inescapable and the pollution exist both indoor and outdoor.

The contributions from manmade activities are: fly ash from power plants, melters and mining operations, smokes from incomplete combustion processes etc. The gaseous include substances that are in the gaseous state at normal temperature and pressure. Manufacture of nylon intermediates. Smoke pollutes the air. Aerosols: They are widely used as disinfectants. At ground level, ozone is an air pollutant—but the ozone that exists in the stratosphere high up in the atmosphere , is exactly the opposite: it's a perfectly natural chemical that protects us like sunscreen , blocking out some of the Sun's harmful ultraviolet radiation. Chlorine, ammonia, hydrogen sulphide, etc. The geographical distribution of human acidic emission sources is not even.

In the former method, the gas is allowed to strike a liquid surface within the collector, and the liquids carrying the trapped gas particles are discharged in an outside collector, from where they are disposed off.

Secondary pollutants are not emitted directly. Air pollution caused from natural sources can be more severe and longer lasting than air pollution from human activities. Such a process allows the passage of UV radiation into earth surface. Among the metallic contaminants arsenic, lead and molybdenum are important. Electrical motorcars and trucks should be developed to reduce the CO2 and CO emissions into the atmosphere. There are four major reasons of air pollution emissions from vehicles, thermal power plants, industries and refineries. Estimates of SO2 in air is made by chemical analysis of the dust collected in a deposit gauge or by a bubbler method. They are really a combination of a specially designed centrifugal form and a dust collector. The equipment used for this purpose may be of different kind ,, viz.
