Vitelogenina como biomarcador de exposição em ictiofauna: uma revisão cienciométrica

Abstract

The contamination of aquatic environments becomes an increasingly significant problem as human population growth occurs. Therefore, monitoring water contamination is important as it needs to address the need to answer what is being altered and why these modifications are occurring. The present study aimed to conduct a scientometric review of the state of the art on vitellogenin acting as an exposure biomarker in fish, presenting trends and scientific gaps, research, critical points on this issue, and identifying directions to guide future efforts. The terms "endocrine disruptors" AND "biomarker" OR "exposure biomarkers" AND "fish" AND "vitellogenin" were searched in the Web of Science between 1999 and 2023. A total of 101 articles were retrieved, selected for their relevant scientific impact (H-index=30), and analyzed using CiteSpace and Excel. There is a clear urgency to direct greater scientific focus and effort towards exploring vitellogenin as an exposure biomarker. The United States, Italy, and Norway lead the number of publications on the topic. Identifying the various types of contaminants present in aquatic environments, as well as investigating the source and how these residues impact the natural environment and affect organisms, especially fish, is crucial. This approach aims to indicate the risk of contamination by endocrine disruptors. Such responses are essential to ensure that the actions taken are effective in reducing damage to the ecosystem, both present and future.
