Experimental studies have shown that nitrogen acid species, particularly nitrous acid, are formed indoors during unvented combustion and by heterogeneous reactions of nitrogen dioxide. Limited measurements support the occurrence of nitrous acid production in occupied homes. The authors report additional measurements of HONO and NO[sub 2] in homes located in Albuquerque, NM, and assess the relationship with housing variables. Indoor HONO concentrations were found to be well correlated with indoor NO[sub 2] levels; HONO concentrations ranged from 5% to 15% of the measured NO[sub 2] concentrations. Given the correlation between HONO and NO[sub 2] in indoor environments, and the plausibility of HONO respiratory toxicity, investigations of respiratory health effects of unvented combustion should consider HONO, in addition to NO[sub 2], as a potentially hazardous indoor pollutant. 38 refs., 2 figs., 2 tabs.
