Peña de Torres, Eduardo de la Carballo, Matilde STP effluents Organic pollutants Solid phase concentration GCyMS Sublethal effects Toxicity 13 paginas, 2 fotografías y 3 tablas estadísticas An integrated approach combining chemistry and biological methods was conducted to assess the toxicity of seven sewage treatment plant effluents.Solid phase concentration procedures were applied to facilitate the study of organic micro pollutants.A chemical analysis was performed by GCyMS.Or ganic fraction toxicity was determined by using bioassays such as Daphnia magna and Chlorella vulgaris tests and sub-lethal effects were also evaluated by using Salmonella typhimurium Test (mutagenicity), recombinant yeast screen (estrogenicity), and Oryzias latipes embryolarval test. More than 49 compounds were detected in the organic fraction due to the various inputs of each effluents. The most frequently detected compounds in the effluents were bisphenol A (BPA), octylphenol (OP), 1,2-benzenedicarboxylic acid, bis(2-ethylhexyl) ester (DEHP) and 1,2-benzenedicarboxylic acid, is(methylpropyl) ester (DBP).Biological assays showed toxicity effects on D. magna tests in all samples, whereas toxicity on C. vulgaris or S. typhimurium tests were not observed.Estr ogenicity and teratogenicity were observed in several samples. The cause-effect relationship could not be established given the high chemical complexity of the effluents and the lack of information available on 70% of the detected compounds subsequent to reviewing various data bases. Nevertheless, due to the high chemical variability revealed by STP effluents, bioassay sets may provide a very useful amount of information for detecting potential toxicity risks.
