Since 1979, the Environmental Agency of São Paulo State in Brazil, CETESB, has been using the Salmonella mutagenicity assay to assess the quality of natural waters. This paper is a compilation of data obtained during the last 20 years from more than a thousand samples. Potencies up to 30,000 revertants/l were observed in 137 positive samples. The Salmonella typhimurium strain TA98 was more sensitive than TA100; 79% of the mutagenicity was detected by this strain, regardless of the presence of… CONTINUE READING
