Although the automotive boom began in the late 1940's, it wasn't until the 1970's that people began to realize that automobiles in the ways that they burned fuel then and now are killing Mother earth and the people that live there. When cars and trucks burn gasoline, air toxins come out of the tailpipes. These air toxins are combustion products--chemicals that are produced when a substance is burned (Clean Air.)

A medley of gases that spew from automobiles pollute our atmosphere, and are fast making the environment a place unfit for living. A combination of unburned Hydrocarbons, Carbon Monoxide, Oxides of Nitrogen combine to spread an obnoxious mixture. When in excess quantity, these tend to cause automobile pollution. Within a certain range they are acceptable, but when the engine is not t

The comprehensive approach to reducing criteria air pollutants taken by the 1990 Act covers many different sources and a variety of clean-up methods. Many of the smog clean-up requirements involve motor vehicles (cars, trucks, buses). Also, as the pollution gets worse, pollution controls are required for smaller sources. However the EPA recently reviewed the current air quality standards for ground-level ozone, or smog, and particulate matter (or PM). Based on new scientific evidence, revisions have been made to both standards. At the same time, EPA is developing a new program to control regional haze, which is largely caused by particulate matter. Under the Clean Air Act, the EPA is required to study whether and how to reduce hazardous air pollutants from small neighborhood polluters such as auto paint shops, print shops, etc. The agency will also have to look at air pollution after the first round of regulations to see whether the remaining health hazards require further!

The Quality of the air we breathe, unfortunately, now depends on the human populous. We know the problems that exist and how they are caused. Regulatory steps have been taken, however, it is believed that stronger measures must be taken with the ever-growing industry and mobilization (more automobiles) of the world. It is up to the people to take responsibility to keep the world's air clean enough to breathe. Cleaner emissions, reduction of automobiles on the roads, and cleaner burning fuels are important factors that we the inhabitants of the world must strive for so that our Earth will be a livable place.

Many provisions and changes have been added to the Clean Air Act. For instance, the Bhopal tragedy inspired the 1990 Clean Air Act requirement that factories and other businesses develop plans to prevent accidental releases of highly toxic chemicals. The Act establishes the Chemical Safety Board to investigate and report on accidental releases of hazardous air pollutants from industrial plants. The Chemical Safety Board will operate like the National Transportation Safety Board (NTSB), which investigates plane and train crashes (Clean Air Act).

2. Ethanol is a safe replacement for toxic octane enhancers in gasoline such as benzene, toluene and xylene.

When fossil fuels (e.g., gasoline) are burned, a variety of pollutants are emitted into the earth's troposphere, or the region of the atmosphere in which we live. Weather and geography determine where smog goes and how bad it is. When temperature inversions occur, warm air stays near the ground instead of rising. If winds are calm, smog may stay in place for days at a time. As traffic and other sources add more pollutants to the air, the smog gets worse.

First, The Environmental Protection Agency, or EPA, and state governors cooperated to identify nonattainment areas for each criteria air pollutant. Then, the EPA classified the nonattainment areas according to how badly polluted the areas are. There are five classes of nonattainment areas for smog, ranging from marginal, relatively easy to clean up quickly, to extreme, in which a large amount of work and a time are needed to clean up (Cleaner Emissions).
