Analytical and Sampling Methodology for Characterization of Polynuclear Aromatic Compounds in Indoor Air

摘要

Sampling and analysis methodology were developed for the collection and quantification of polynuclear aromatic hydrocarbons, their nitro derivatives, and their nitrogen heterocyclic analogs in indoor air. The methodology was evaluated in a study of air in ten homes. The study included homes with and without woodburning fireplaces, gas heat and appliances, and smoking occupants, and with a range of ventilation rates. The range of concentrations in the homes and factors that systematically contribute to those concentrations of selected polynuclear aromatic compounds were estimated. Some practical limitations on the sampling equipment and methodology were identified.
