In recent years, there has been a growing concern over the potential hazard of certain constituents in particulate suspended in the atmosphere. One constituent which has received considerable attention recently is particulate nitrate. Nitrate has been found to act as a respiratory irritant, especially to those who suffer from asthma. Nitrate is also suspected as one of the agents responsible for the lowering of pH in freshwater lakes.
