Pyrolysing insecticidal coils: air pollution by polycyclic aromatic hydrocarbons and other mutagens detected by the Salmonella/microsome test.
Pyrolysing insecticidal coils, which are used commonly for their evaporative release of insecticidal amounts of pyrethrins, have been investigated with respect to the emission of airborne particles, their mutagenic activity in the Salmonella/microsome mutagenicity test and their polycyclic aromatic hydrocarbons (PAH) content. Emitted particles contain compounds that are mutagenic in the absence of exogenous activation, as well as components that require mammalian activation. The particles also contain a range of PAH, but their concentration cannot account for the mutagenic response with mammalian activation. The use of pyrolysing insecticidal coils in semi-enclosed spaces may cause air pollution by releasing mutagenic and carcinogenic compounds that are of a magnitude similar to that found in other air pollution situations.
