In 1970, the United States created the EPA and passed the Clean Air Act,
marking the beginning of the struggle to control pollution. The act originally
empowered the EPA to determine safe limits and regulate six major air
pollutants, now expanded to include 189 potential threats. Thanks to these
tighter regulations and improved technology, the United States has enjoyed huge
reductions in airborne lead, sulfur compounds and chlorofluorocarbons. Concentrations
of carbon monoxide that was once spewed by every car and truck
have dropped by about 90 percent in large American cities. Concentrations of
particulate matter, a classification covering a wide range of pollutants in the
microscopic to near-microscopic range, have dropped by about 80 percent from
their peak, and ozone has dropped as well. The result: from 1980 to 2000,
according to a 2009 study in the New England Journal of Medicine, average
life expectancy increased five months because of the nationwide drop in air
pollution (Berry). The EPA set some of its early pollution standards based on
“challenge studies“ in human volunteers. In the 1970s, people with asthma,
coronary artery disease and other conditions were exposed to ozone and carbon
monoxide in a lab. Their lung capacity dropped and their blood vessels
constricted “at lower levels of exposure than had been expected,” says Daniel
Greenbaum, president of the Health Effects Institute. As a result, the EPA
pushed for stricter standards, and by 1975 catalytic converters were mandatory
on new vehicles (Berry). In the case of Egypt, it is plausible and attainable
to create such an act that helps in the decrease and prevention of air
pollution. Even though the US is a developed country and Egypt is yet a
developing country, the basis of such an act could be applied like testing
different levels of pollution on certain groups of people an creating new laws
for citizens all around Egypt to abide by for a safer and healthier future.
