Abstract: The environmental risks of pesticides found in surface waters of an important agricultural basin in Brazil were estimated by adopting two approaches: individual pesticides risk quotients (RQ) and concentration addition model for pesticide mixtures (RQs) contained in each water sample. Monitoring was carried out in the Mogi Guaçu River basin, Brazil, from October 2017 to May 2018. Four sampling points were selected in the Mogi Guaçu River and seven in its tributaries A multiresidue method with solid-phase extraction and subsequent analysis by UPLC-ESI-QqQ-MS/MS was developed to quantify 19 pesticides. Herbicides, except for simazine, presented the highest detection frequencies with values above 70%. Tebuthiuron was found in all 55 analyzed samples, presenting the highest concentration (6437 ng L-1) over the monitoring period. Fungicides and insecticides showed similar detection frequency (DF) values, ranging from 1.8% to 21.8%. Tebuconazole and carbofuran were the fungicides and insecticides most frequently detected, respectively. January 2018 sampling showed the highest total concentration of pesticides, differing from March 2018 and May 2018 (p < 0.05). The MG2 > TMG8 > MG1 > TMG6 sites showed the highest concentration total of pesticides while MG4 > TMG4 > TMG3 (p < 0.05) sites showed the lowest values: MG4 > TMG4 > TMG3 (p < 0.05). Most pesticide occurrences presented no risks to aquatic organisms. Only 19 out of the 175 pesticide occurrences > LOQ presented individual risks to aquatic biota. Contrary to the results obtained by the individual risk assessment, most pesticide mixtures presented risks to aquatic biota. In 36 out of the 55 samples analyzed during monitoring, pesticide mixtures presented risks to aquatic life.

A presente interpretacao visa avaliar as potencialidades agricolas das terras levando-se em consideracao as condicoes do meio ambiente, propriedades quimicas e fisicas das diferentes classes de solo e a viabilidade de melhoramento relativo aos fatores: fertilidade natural, excesso de agua, deficiencia de agua, suscetibilidade a erosao e impedimentos a mecanizacao. A avaliacao da aptidao agricola, em sintese, consiste em posicionar as terras dentro dos seis grupos de aptidao, visando mostrar o uso mais adequado de uma determinada extensao de terrra, em funcao da viabilidade de melhoramento dos fatores basicos e do grau de limitacao que por acaso possam existir apos a utilizacao de praticas agricolas inerentes aos sistemas de manejo adotado. |
