However, due to the actions of humans, water resources have been contaminated by many different compounds, including pesticides. Pesticides in water sources can cause damage to aquatic environments or to those who consume it. On this basis, it is important that water treatment systems can remove these pollutants from water. In this perspective, the objective is to investigate whether conventional water treatment can remove several pesticides, namely, atrazine, ametryn, malathion and chlorpyrifos. According to the results, it was observed that conventional treatment after filtration was not capable of removing these pesticides efficiently, with the organophosphorus pesticides (malathion and chlorpyrifos) removed in a higher percentage than the triazines (atrazine and ametryn). Post-chlorination reduced the pesticide levels, however, malaoxon and ametryn sulphoxide by-products were generated, which caused greater acetylcholinesterase inhibition. 2018 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42956169010 https://www.redalyc.org/journal/429/42956169010/ https://www.redalyc.org/journal/429/42956169010/html/ https://www.redalyc.org/journal/429/42956169010/42956169010.epub https://www.redalyc.org/journal/429/42956169010/movil https://doi.org/10.26850/1678-4618eqj.v43.2.2018.p65-73 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.2 Vol.43 |
