CENÁRIO GLOBAL COM PESQUISAS ENVOLVENDO CONTAMINANTES AGRÍCOLAS EM SISTEMA ENDÓCRINO DE PEIXES

Abstract

The purpose of this work was to evaluate scientific trends concerning the effect of pesticides on the endocrine system of fish. Data were compiled using database from Web of Science, Scopus and Scielo. The screening identified studies from 1970 to 2017, the final date established for the investigation. A significant increase in publications occurred for this period (r = 0.83, p <0.0001). It was observed that most of the studies occurred ex situ, and pesticides such as endosulfan, dichlorodiphenyltrichloroethane (DDT) along with its metabolic dichlorodiphenyldichlorethylene (DDE), atrazine and chlorpyrifos were the most investigated. On the other hand, the groups of pollutants most studied in situ were organochlorines, organophosphates and alkylphenols. Countries such as the United States, China and India dominated the research. The most researched species were zebrafish (Danio rerio), rainbow trout (Oncorhynchus mykiss) and medaka (Oryzias latipes). Effects such as hormonal changes, histological changes, genetic expressions and gonadal damages were expressive in fish in the presence of these chemicals. These data show the first global temporal assessment of the effect of pesticides on the endocrine system of fish. Future studies may explore, for example, in situ data and virtue of this area is still in short supply in research for endocrine analysis
