在许多亚洲国家，尤其是在中国，烧香是一个不可忽视的室内空气污染源。对香的形成及其散发缺乏监管。在此，重要的颗粒相有毒化合物，母体多环芳烃（pPAH），烷基化多环芳烃（APAHs），氧化多环芳烃（OPAH），硝基多环芳烃（NPAH）和环己烷的排放因子（EF）是从燃烧最具代表性的中国香（即，五个尼木藏香[NTI]，一个普通的烟雾香[SI]，一个无烟香[SFI]）。NTI的定量有机物（EF =有机物）的总EF平均为7.44 ± 2.72 μg g− 1，在SI至SFI的水平内。其中pPAHs的含量最高（41.5%~ 63.7%）。所有受检香的总致癌风险均严重超过1 × 10−4的健康风险阈值，证实了烧香对人体健康具有一定程度的危害。值得注意的是，NTI和SFI燃烧的有机成分相似，EF和吸入寿命癌症风险低于SI。本研究结果提示，在需要焚香的情况下，NTI或SFI的高级香应该是比SI更好的选择。这为居民、游客和工作人员选择在住宅或寺庙中提供较低有毒物质排放的熏香提供了指导。此外，香排放物的高健康风险警示，对香的生产和排放制定更严格的法规是强制性的。
Incense burning is a nonnegligible indoor air pollution source in many Asian countries, particularly in China. There is a lack of regulation on the formations of incense and its emissions. Herein, the emission factors (EFs) of important particulate phase toxic compounds, parent polycyclic aromatic hydrocarbons (pPAHs), alkylated PAHs (APAHs), oxygenated PAHs (OPAHs), nitro PAHs (NPAHs), and cyclohexanes were determined from the burning of the most representative types of Chinese incenses (i.e., five Nimu Tibetan incenses [NTI], one ordinary smoke incense [SI], and one smoke-free incense [SFI]). The total EFs of the quantified organic species (EFΣorganics) for NTI was 7.44 ± 2.72 μg g−1on average, within the levels of SI to SFI. The pPAHs showed the largest proportion (41.5%–63.7%) of the total quantified organics. The total cancer risks for all examined incenses severely exceeded the health risk threshold value of 1 × 10−4, verifying that incense burning poses certain extent damage to human health. Notably, the organic compositions of NTI and SFI burnings were similar, with lower EFs and inhalation lifetime cancer risks than SI. The present results suggest that the advanced types of incenses of NTI or SFI should be better choices than SI while the incense burning is necessary. This acts as a guide for the residents, visitors, and workers in the selections of incenses that offer lower toxic substances emissions in dwellings or temples. In addition, the high health risks for incense emissions alert the establishment of more restrictive regulations on incense production and emission are compulsory.
