- W2047364998 abstract "The present study was carried out on the waters of the Caí River (Rio Grande do Sul, Brazil) in an area under the influence of a petrochemical industrial complex, as the continuation of a study in which the mutagenic activity of water samples was evaluated in the internal area of this complex. In the previous study, the release of inducing substances was detected, revealing the need for a full analysis of the real ecological impact of the industrial complex on the river. Water samples from different sites along the Caí River were subjected to the Ames test during a study of 20 months duration for the detection of possible mutagens. Strains TA100 and TA98 were used for initial sample screening in the presence and absence of the S9 mix at a standard dose of 2000 microliters/plate. When positive activity (values equal to twice the spontaneous mutation rate) and/or cytotoxic activity (cell survival below 60%) was detected, the dose-response relationship was studied. Thirty-four percent of the samples tested were mutagenic, with different values according to collection site. Of the total number of positive responses, 6% were obtained for samples collected at the blank site upstream from the area studied, 82% at sites closest to the industrial complex, and 12% in downstream areas. Strain TA98 was the most sensitive in assays with no metabolic activation. A low frequency of induction (2%) was observed for strain TA102. Application of the Ames test permitted the delimitation of three areas of influence of the petrochemical industrial complex, and the test proved to be adequate for the detection of contaminants from the petrochemical industry." @default.
