Through the State Implementation Plan (SIP), the TNRCC's goal is to "improve air quality to a degree that is beneficial" for human health. .
Ozone & NOx.
Ozone is a reactive form of oxygen that exists in two portions of the atmosphere. When it is naturally occurring in the upper atmosphere, it can be beneficial to society, as it protects life from harmful ultraviolet rays from the sun. When it exists in the troposphere (lower levels of the atmosphere), it is called ground-level ozone. At this level, ozone can also protect people from harmful ultraviolet light, but it nevertheless has several adverse effects. .
Ground-level ozone is mainly formed by chemical reactions of nitrogen oxides (NOx) and volatile organic compounds (VOCs) in sunlight. Due to sunlight and meteorological effects, high temperature areas like Houston and Los Angeles are prone to higher ozone levels. Presently, the acceptable EPA one-hour ozone standard is 12 parts per million (ppm), obtained by taking an average of one-hour concentration of ozone. Counties must not exceed this threshold more than three times per year to remain in attainment. In 1997, the EPA established a new standard at a threshold of .08 ppm for an eight-hour standard. This standard will be enforced within the next decade, and like the previous standard, ozone level averages must not exceed the standard more than three times per year to remain in attainment. For regions like Houston-Galveston, currently not in attainment, the EPA and TNRCC concentrate on the previous, less stringent standards first. The new rules will eventually bump non-attainment counties in the US from 106 to 335. The Houston-Galveston area is focusing on meeting current rules first. .
Volatile organic compounds (VOCs) are important ingredients in the creation of ozone. VOCs are emitted by industrial sources (petrochemical plants, oil refineries, petroleum storage tanks) and also mobile sources (automobiles, trucks, motorcycles, airplanes, construction equipment).

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. ... A more notable interest group founded in 1996, Clean Air Task Force (CATF), is committed to restoring healthier air through education and research. ... The Clean Air Task Force works valiantly along side with the Environmental Protection Agency. ... The EPA was established in December 1970 to help uphold the standards and regulations of the Clean Air Act of 1970. ... It also forces residents of heavily-polluted areas to wait year...
The Plants for Clean Air Council and Wolverton Environmental Services have tested different houseplants for their ability to remove various toxic gases such as formaldehyde, xylene/toluene, and ammonia. ... Given that air also reaches plant roots, uptake by root tissues is another means by which air can be purified. ... Selection of houseplants to mitigate air pollution in offices and homes depends not only on their ability to clean the air but also on their growth habit, the ease of growing and maintaining them, their light requirement, and, of course, your personal taste. ... Finally, the ...
Air Pollution Air Pollution is addition of harmful substances to the atmosphere resulting in damage to the environment, human health, and quality of life. ... When fuels are incompletely burned, various chemicals called volatile organic chemicals also enter the air. ... In the weather phenomenon known as thermal inversion, a layer of cooler air is trapped near the ground by a layer of warmer air above. When this occurs, normal air mixing almost ceases and pollutants are trapped in the lower layer. ... Air pollution can expand beyond a regional area to cause global effects. ...
Problems Caused By Air Pollution Some people think that air pollution is not harming the earth or the people, but it is doing worse, by killing the earth and getting people sick. ... First, air pollution causes a great deal of health problems. Wanting clean air is a good reason because air that is polluted can damage human health. ... In conclusion, air pollution is killing the earth and its people. ... - For better efficiency, clean furnace and air condition filters...
"Thermal inversion is when a layer of cooler air is trapped near the ground by a layer of warmer air, when this occurs normal air mixing almost ceases and pollutants are trapped in the lower layer (Hart, 4)." This causes the ground level air to basically be a pollution trap. ... There are many things that have been done for the earth's protection through acts such as The Clean Air Act of 1970 and treaties like the 1992 Untied Nation's Climate Change negotiation putting restrictions on the amount of pollutants like CFC's allowed to be used. ...
