Toxic Organic Pollutants Impact

Abstract Organic extracts of emissions from wood combustion have been fractionated by high performance liquid chromatography (HPLC) into 25–28 fractions. Each fraction was tested for mutagenic activity in a modified Ames Salmonella /microsome bioassay requiring one‐third of the test volumes needed for the ususal test. Direct mutagenic activity was noted predominantly in the most polar fractions, whereas indirect mutagenic activity was associated with the fractions containing polycyclic aromatic hydrocarbons (PAH) and with polar fractions probably consisting of aza‐arenes and aromatic amines.
