Air Pollution
Air Pollution can be taken as a wide variety of problems. The first type is known as particulate matter. This is made up of aerosols that become suspended in the earth’s atmosphere. These materials arise from the industrial processes and the burning of coal. Atmospheric particles can scatter and absorb sunlight which reduces visibility. Particles also reduce the visibility by fading the light from objects and illuminating the air causing the contrast between the objects and their backgrounds to reduce. Not only does it affect visibility, but it speeds up the erosion of buildings and the corrosion of metals, interferes with the respiratory system, and brings toxic chemicals into the body. The small particles cause chronic bronchitis, bronchial asthma, emphysema and lung cancer (Hodges 59). The second type is sulfur oxides which come from the industrial processes and the burning of coal. Damage to materials, vegetation, and the respiratory system are caused by the acid in oxides. Small quantities of sulfur can increase illness and mortality (Hodges 59). Oil with lower levels of sulfur have begun to be used to formulate gasoline that is used in today’s cars. The third type of pollutant is carbon monoxide. Carbon mono
There wasn’t any legislation on the horizon until the 1950’s. The first federal legislation appeared in 1955 with the Air Pollution Control Act. The Motor Vehicle Air Pollution Act was passed in 1965, regulating national automobile emissions for the first time. Then the Air Quality Act of 1967 was passed, providing funds for federal research and designating air quality control regions to help establish air pollution standards. In the United States, the serious effort against local and regional air pollution began with the Clean Air Act of 1970, which was amended in 1977 and 1990. This law requires that the air can contain no more than specified levels of particulate matter, lead, carbon monoxide, sulfur dioxide, nitrogen oxides, ozone, and various toxic substances (Encarta). A more notable interest group founded in 1996, Clean Air Task Force (CATF), is committed to restoring healthier air through education and research. “CATF works closely with more than 40 state, local, regional and national organizations to educate the public, media, industry and public decision makers on the science and economics of clean air policies through fact-based and locally appropriate advocacy” (CATF). Their main concerns for the quality of our air is regulating and enforcing individual state’s policies. CATF has been a strong supporter and valid lobbyist group since 1996. The Clean Air Task Force works valiantly along side with the Environmental Protection Agency. The EPA works alongside Congress to uphold environmental laws passed and bring new legislation to the forefront. The EPA was established in December 1970 to help uphold the standards and regulations of
