Gas and fine particulate phase N-Nitroso and nitrite organic compounds in the atmosphere

摘要

Phtotochemistry between gas phase orgaic compounds, No_x and ozone is expected to reuslt in the formation of nitrogen containing compounds of toxicological importance. Classes of potentially toxic organic compounds which may form include nitro-, N-nitroso-and nitrite-substituted compounds. The compounds are expected to be labile, semi-volatile organic compounds in equailibrium between the gas and particulate phases in the atmosphere. The phase distribution of these potentially toxic semi-volatile organic compounds can be determined using diffusion denuder samplers.
