Resumo: This research aimed to evaluate the phytotoxicity of surface waters of the São Paulo metropolitan region using bioassays based on Sinapis alba L. (mustard). Three sampling campaigns were carried out during the dry season of 2017 (minimum dilution of pollutants) and samples were collected in triplicate at two locations (Reference and Ribeirão Pires stream). The assays were performed in triplicate to increase the degree of reliability of the information obtained. The observed responses were: root growth of S. alba, relative percentage of germination, relative percentage of root growth, Germination Index (GI). Electrical conductivity and total dissolved solids were also measured in situ using a multiparametric probe. The reference samples were classified as non-phytotoxic (IG = 93.55 ± 0.17%), while Ribeirão Pires stream samples showed moderate phytotoxicity (IG = 70.88 ± 0.25%). Thus the discharge from the Ribeirão Pires stream into the billings dam poses a risk to the water quality of the dam, especially where this stream drains.

Foram realizadas 3 coletas no período de seca de 2017 (menor diluição de poluentes). As coletas foram realizadas em triplicata, em duas estações de amostragem (Referência e Córrego Ribeirão Pires). As variáveis respostas observadas foram: o crescimento radicular da S. alba, a porcentagem relativa de germinação, a porcentagem relativa de crescimento radicular, o Índice de Germinação (IG), além da aferição in locu da condutividade elétrica e dos sólidos dissolvidos totais, utilizando sonda multiparamétrica. As amostras da estação Referência foram classificadas como não fitotóxicas (IG = 93,55 ± 0,17%), enquanto as amostras do Córrego Ribeirão Pires apresentaram fitotoxicidade moderada (IG = 70,88 ± 0,25%). Desse modo, o despejo de águas residuárias no Córrego Ribeirão Pires oferece risco à manutenção da qualidade da água da Represa Billings, onde esse córrego deságua.Universidade Federal de Campina Grande - UFCG2018-05-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/8510.22571/2526-433885Acta Brasiliensis; Vol 2 No 2 (2018): Acta Brasiliensis; 58-62Acta Brasiliensis; Vol 2 No 2 (2018): Acta Brasiliensis; 58-62Acta Brasiliensis; Vol 2 No 2 (2018): Acta Brasiliensis; 58-622526-43382526-432Xreponame:Acta Brasiliensis (Online)instname:Universidade Federal de Campina Grande (UFCG)instacron:UFCGporhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/85/40Copyright (c) 2018 Acta Brasiliensisinfo:eu-repo/semantics/openAccessKohatsu, Marcio YukihiroJesus, Tatiane AraújoCoelho, Lucia Helena GomesPeixoto, Damáris CristinaPoccia, Geovana TognellaHunter, Colin2021-07-12T20:04:08Zoai:ActaBra.revistas.ufcg.edu.br:article/85Revistahttp://revistas.ufcg.edu.br/ActaBraPUBhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/oaiactabrasiliensis@gmail.com || actabrasiliensis@gmail.com2526-432X2526-4338opendoar:2021-07-12T20:04:08Acta Brasiliensis (Online) - Universidade Federal de Campina Grande (UFCG)false
