dc.description.abstractA wide range of industrial and domestic wastes are discharged in the River Tieté in the region of Suzano and the biological treatment of effluents is carried out by Wastewater Treatment Plant of SABESP (WWTP Suzano). The samples were collected and transported by SABESP (Companhia de Sancamento Bésico do Estado de Sio Paulo). The following points were chosen: PO - Ponte Nova Dam, P1 — 200 meters upstream to the plant-, P2— the affluent of plant, P3 — the effluent treated by plant before discharge in the river and P4 — 200 meters from the discharge in the river—The samples were evaluated by analyzing acute toxicity and dominant lethal test was performed for detection of germ cell mutations in freshwater snails Biomphalaria glabrata. Acute toxicity assays were conducted in adult specimens and embryo at blastulae, gastrulae, trocophore and veliger stages. Four sampling were performed. In samples at august 2006 and august 2008, the station affluent was toxic for embryos and adults. The results were similar, with LC50 values; 43,04%, 41,56%, 57,16% and 60,06% for embryos at blastulae, gastrulae, trocophore and veliger stages respectively and 100% for adult snails in first sample and 48,24%, 43,71%, 55,43% and 62,64% for embryos at blastulae, gastrulae, trocophore and veliger stages respectively and 84,16% for adult snails in august 2008. Sampling at february 2007 was toxic only for adult snails, with a LC,, value of 41,25% and sampling at february 2008 was not toxic for adults and embryos. In all samplings, after discharge into the river, treated effluents were not toxic for B. glabrata adults and embryos. There was no mutagenicity in all samples. In these study, the potential impact of effluent discharge to the biota of Tieté River was showed. These results show the importance of the WWTP biological treatment of effluents in reducing acute toxicity.
