亚硝酸（HONO）可以由二氧化氮的非均相反应和燃烧源的直接排放产生。氮氧化物与臭氧的相互作用对室外光化学反应具有重要意义。然而，人们对室内HONO水平或居住房屋中HONO与NO(2)和O(3)浓度之间的关系知之甚少。在南加州的两个社区，使用被动采样器同时测量了这三种污染物为期六天的室内和室外综合浓度。室内平均HONO浓度为4.6 ppb，而室外的HONO浓度为0.9 ppb。室内和室外的平均NO(2)浓度分别为28和20.1 ppb。与室外水平（平均56.5 ppb）相比，室内O(3)浓度较低（平均14.9 ppb）。住房特征，包括社区和燃气灶的存在，与室内NO(2)和HONO浓度显著相关。室内HONO水平与室内NO(2)水平密切相关，约占室内NO(2)浓度的17%。室内HONO水平与室内O(3)水平呈负相关。测量结果表明，住宅室内存在大量的HONO浓度以及三种室内空气污染物之间的关联。
Nitrous acid (HONO) may be generated by heterogeneous reactions of nitrogen dioxide and direct emission from combustion sources. Interactions among nitrogen oxides and ozone are important for outdoor photochemical reactions. However, little is known of indoor HONO levels or the relationship between residential HONO, NO(2), and O(3) concentrations in occupied houses. Six-day integrated indoor and outdoor concentrations of the three pollutants were simultaneously measured in two communities in Southern California using passive samplers. The average indoor HONO concentration was 4.6 ppb, compared to 0.9 ppb for outdoor HONO. Average indoor and outdoor NO(2)concentrations were 28 and 20.1 ppb, respectively. Indoor O(3) concentrations were low (average 14.9 ppb) in comparison to the outdoor levels (average 56.5 ppb). Housing characteristics, including community and presence of a gas range, were significantly associated with indoor NO(2) and HONO concentrations. Indoor HONO levels were closely correlated with indoor NO(2) levels and were about 17% of indoor NO(2) concentrations. Indoor HONO levels were inversely correlated with indoor O(3) levels. The measurements demonstrated the occurrence of substantial residential indoor HONO concentrations and associations among the three indoor air pollutants.
