✦ Synopsis
Mutageniccharacterization wasapplied to studytheenvironmental compartmentsof a heavily industrialized area. Polycyclic aromatic hydrocarbons have been previously detected in the environmental samples of different compartments. Salmonella typhimurium strains TA98 and TAlOO were used for screening the mutagenic activity of airborne particulate matter, sediments, surface waters, and industrial wastewaters. The tests were performed with and without S9 metabolic activation. Results of the tests showed mutagenicity in those assays with metabolic activation. Sampling points with higher activity reached a value of 25,258/44,106 His+ rev/g in airborne particulate matter samples and 8,549,500/5466 His+ rev/L water samples, for strains TA98 and TA100, respectively, and 15,128 His+ revlg in sediment samples for TA98. Apparently, a strong mutagenicity in water and sediment samples is associated with sectors near point sources of pollution.
