摘要：

We have evaluated the mutagenicity of dichloromethane extracts of combustion particles from several biomass fuels that are commonly used in developing countries in Salmonella strains TA98 ± S9 and TA100 ± S9. Combustion-particle extracts from dried cow dung and crop residue exhibited mutagenic potencies similar to wood-smoke extracts (0.0 - 1.0 rev./μg extract). However, extracts from coconut-shell-smoke particles showed relatively potent direct-acting mutagenicity (1.6 rev./μg, TA98 - S9. Results from testing this sample in nitroreductase- and acetylase- deficient strains TA98NR and TA98 (1,8-DNP-6) revealed no contribution from nitroarenes. © 1990.
