Agrochemical use for crop protection may increase as a result of significant changes in pest abundance and behavior caused by human-caused climate change. Pesticides have been employed in agricultural contexts to manage weeds, diseases, and pests. However, their harmful impacts on beneficial insect groups that contribute to the upkeep and sustainability of agroecosystems have received not much attention. The widespread use of pesticides in industries, agriculture, and households poses risks to human health and natural environments, to fully assess their impact, one must consider their sublethal impacts on aquatic species and behavior, in addition to the direct mortality caused by them. The harmful effects of pesticides and insecticides are also causing climate change, which has altered the dynamics of many different types of pests. Additionally, it has an effect on the distribution and number of pests in coastal areas as a result of changes in sea levels. The present study investigates the use toxicological investigation of pesticides and herbicides in aquatic environments and the authors attempted to study the most recent research on pesticides and their impact on aquatic systems and the mitigation approach to remove these contaminants. The data presented here outlines the disadvantages of pesticide use as well as the advantages of various remediation procedures used to prevent or limit pesticide leaching and bioavailability in soil.
