air pollution
One of the formal definitions of air pollution is as follows - 'The presence in the atmosphere of one or more contaminants in such quality and for such duration as is injurious, or tends to be injurious, to human health or welfare, animal or plant life.' It is the contamination of air by the discharge of harmful substances. Air pollution can cause health problems and it can also damage the environment and property. It has caused thinning of the protective ozone layer of the atmosphere, which is leading to climate change. Modernization and progress have led to air getting more and more polluted over the years. Industries, vehicles, increase in the population, and urbanization are some of the major factors responsible for air pollution. The following industries are among those that emit a great deal of pollutants into the air: thermal power plants, cement, steel, refineries, petro-chemicals, and mines. Air pollution results from a variety of causes, not all of which are within human control. Dust storms in desert areas and smoke from forest fires and grass fires contribute to chemical and particulate pollution of the air. POLLUTANTS AVERAGE TIME CONCENTRATION
However, fine particles are released when garbage is burned and can contribute to smog and damage human health. In 1992, the World Bank designated indoor air pollution in the developing countries as one of the four most critical global environmental problems. The main pollutant in this environment is the SPM. Vehicles and industries are the major source of ground-level ozone emissions. Scientists must then determine how much exposure to pollutants is harmful. By the end of the 19th century, many people visited London to see the fog. Toxic Organic Micro pollutants TOMPs (Toxic Organic Micro pollutants) are produced by the incomplete combustion of fuels. Ground-level ozone forms when pollutants released from gasoline and diesel-powered vehicles and oil-based solvents react with heat and sunlight. Only through the efforts of scientists, business leaders, legislators, and individuals can we reduce the amount of air pollution on the planet. They comprise a complex range of chemicals, some of which, although they are emitted in very small quantities, are highly toxic or carcinogenic. Pesticides, if used carefully and the manufacturers, instructions followed carefully they do not cause too much harm to the indoor air. Restricting smoking is an important key to a healthier environment. London had one of its worst experiences with smog in December 1892. In the United States, most household products come with instructions about safe use. Finally, lead levels, although still high, decreased 30% between 1999 and 2000.
