Abstract:
|
Air quality indicators can take many different forms. The question that needs to be answered is: "Why are they needed?" We live in a technical society that collects vast quantities of environmental data. Indicators are needed to translate this environmental data into a form that is readily understood. They are designed to simplify. Those asking questions seek answers in the simplest form. Is the environmental problem becoming better or worse? Often the questioner is told the problem is "too complex." The governmental official or scientist may prefer to give no answer at all than give an imperfect answer that could lead to a misunderstanding. The layman prefers an imperfect answer to no answer at all. An indicator must be able to translate complex information into a form that is readily understood by decision-makers, as well as laymen. In order to accomplish this, different indicators are proposed for different pollutants or combinations of pollutants. This paper will compare traditional EPA trend methodology with both meteorological adjusted trends and population and land area weighted trends.
