Abstract:
... Long-term exposure of contaminants to emerging concern (CECs) may pose risks to human health and ecosystems, even at low concentrations. Rivers impacted by both agricultural and urban activities experience distinctive environmental pressures due to receiving wastewaters that contain complex organics and their transformation products (TPs). In this study, we developed a regional database composed o ...

Abstract:
... The practice of intensive herbicide use in the sugarcane industry has a high risk of compromising the quality of the water and the organisms that live there due to losses through runoff, leaching and other processes. In this work, the dynamics of four herbicides present in three different mixtures were evaluated through their incorporation and elimination in the muscle tissue of tilapia (Oreochrom ...

Abstract:
... The aim of this study was to evaluate the selectivity of herbicides, insecticides, and fungus Metarhizium anisopliae (Metsch.) on the immature stages of Trichogramma galloi Zucchi. Egg masses of Diatraea flavipennella Box, 1931, containing 30 eggs each, were immersed in test solutions for 5 s, before and after parasitism. In the post-parasitism tests, eggs were treated when they reached the egg–la ...

However, reports on its environmental risk assessment with regard to soil and crop contamination are limited. In this study, accumulation of ametryn in wheat, maize, ryegrass and alfalfa crops along with ametryn residues in the soil planted wi ...
