Article Synopsis
- Understanding the environmental impact of pesticides requires knowledge about their photochemical behavior, especially concerning micropollutants in Brazilian rivers.
- The study focuses on the Pontal of Paranapanema region, known for a high concentration of sugarcane crops, analyzing how surface waters attenuate these micropollutants across different seasons.
- Using the APEX model, researchers simulated the concentration of reactive intermediates in the water, finding varying levels of hydroxyl radicals and other intermediates while also predicting the persistence of specific pesticides like atrazine and diuron, which had half-lives ranging from a few hours to a week.
