Carcinogenic or cocarcinogenic effects of NO2, O3, and SO2 have not been proven to date with sufficient reliability. However, nitrosamine formation after exposure to NO2- or O3-induced decrease in benzpyrene hydroxylase are potential hazards. A final revaluation of a possible cocarcinogenic action of SO2 requires further experimental studies.
迄今为止,二氧化氮、臭氧和二氧化硫的致癌或促癌作用尚未得到充分可靠的证实。然而,接触二氧化氮或臭氧导致苯并芘羟化酶减少后形成亚硝胺是潜在的危害。对二氧化硫可能的促癌作用进行最终重新评估需要进一步的实验研究。
