Causes and effects of contamination of water sources due to excessive use of agrochemicals and pesticides: bibliometric analysis

This article conducts a bibliometric analysis of water pollution caused by agricultural pesticides, focusing on theoretical and methodological trends. The analysis uses Scopus databases and Bibliometrix and VOSviewer software tools to analyze 2,330 documents from 2013 to 2022. The research highlights the importance of environmental, agricultural, and biological sciences in addressing water pollution. The study suggests improving pesticide use, reducing fertilizer applications, and addressing the harmful impacts of contaminated fish on human health. The restriction of glyphosate use in the European Union caused economic losses for companies, and a follow-up on glyphosate use in crop applications was proposed. The study also evaluates chemical concentrations and recommends addressing aquatic ecotoxicological risks. Future research trends include increasing water use efficiency and quality, hydrogeological studies, watersheds and land use, and climate modeling and impacts. The research is unique in addressing both research trends and knowledge gaps in water pollution research in various aspects.
