Mathematical modeling of chemically reactive pollutants in indoor air

Abstract

A general mathematical model is presented for predicting
\nthe concentrations of chemically reactive compounds in indoor air. The model accounts for the effects of ventilation, filtration, heterogeneous removal, direct
\nemission, and photolytic and thermal chemical reactions.
\nThe model is applied to the induction of photochemically
\nreactive pollutants into a museum gallery, and the predicted
\nNO, NO_x-NO, and O_3 concentrations are compared to measured data. The model predicts substantial production
\nof several species due to chemical reaction, including
\nHNO_2, HNO_3, NO_3, and N_2O_5. Circumstances in which homogeneous chemistry may assume particular importance
\nare identified and include buildings with glass walls, indoor combustion sources, and direct emission of olefins.
