Nitrous acid (HONO) exists as an atomospheric gas [1]. HONO as well as nitrogen dioxide (NO2) is a primary product of material combustion [2]. A significant positive correlation has been observed between the HONO and NO2 levels in homes and offices [3]. Moreover, conventional assays of NO2, such as the Saltzman reagent method and the NOx analyzer, measure HONO as NO2 [4]. Therefore, previous studies on the respiratory effects of NO2 may have included exposure to HONO without the independent measurement of the exposure to and effects of HONO [5].

Nitrous acid, a component of photochemical smog and a common indoor air pollutant, may reach levels of 100 ppb where gas stoves and unvented portable kerosene heaters are used. Nitrous acid is a primary product of combustion and may also be a secondary product by reaction of nitrogen dioxide with water. Because the usual assays for nitrogen dioxide measure several oxides of nitrogen (including ...
