South America is underrepresented in research on air pollution exposure disparities by sociodemographic factors, although such disparities have been observed in other parts of the world. We investigated whether exposure to and information a...
Mutagenic Atmospheres Generated from the Photooxidation of NOx with Selected VOCs and a Complex Mixture: Apportionment of Aromatic Mutagenicity for Reacted Gasoline Vapor [0.03%]
NOx与某些挥发性有机物及复杂混合物光氧化生成致突变性的大气：反应汽油蒸气芳香族物质的分配比例
Jonathan D Krug,Theran P Riedel,Michael Lewandowski et al.
Jonathan D Krug et al.
The interaction of sunlight with volatile organic compounds (VOCs) emitted from various sources results in mutagenic photooxidation products that contribute substantially to air pollution. Evaporation of gasoline is one such source of VOCs;...
