Because the acidic aerosol has a unique component of variation, it may be possible to distinguish health effects due to this specific pollutant from other available pollution indices or environmental factors.
So far it is still an unresolved scientific question to separate the independent effects of individual air pollutant from multiple-pollutant models in short-term effects studies of air pollution.
Trickling filters remove up to 85 percent of organic pollutant from sewage.
Tribe's main argument lies in the claim that Section 111 d) of the Clean Air Act says that the EPA can't regulate an air pollutant if it's already regulating another pollutant from the same source.
