Introduction. Due to the residual character and high level of toxicity of endosulfan, worldwide concern for its environmental impact has increased. Therefore, the search for analytical methodologies that allow its detection and quantification continues to be a topic of current research. Endosulfan properties and its degradation pattern confer it characteristics that make very complex the problematic while the pesticide and its metabolites are extensively spread throughout the atmosphere and contaminate both lipophilic and hydrophilic matrixes. Objective. To conduct a review on some recent research about the endosulfan problematic including chemical aspects, environmental issues and immunochemical techniques for its analysis, which is an area of current interest in this research group at Universidad de Caldas. Method. This review article analyzes qualitatively scientific literature from Science Direct, PubMed, Scielo databases and official Web pages using key words such as endosulfan, endosulfan immunochemical analysis, endosulfan environmental problematic, endosulfan international regulations, endosulfan current normativity and instrumental methods for the analysis. Results. Relevant information related to the proposed objective was found which is presented in 3 sections: chemical aspects of endosulfan, environmental issues, and immunochemical techniques for its analysis. Conclusions. Endosulfan has been banned by international organizations. However, the pesticide is still being used in some countries and is easily spread to other regions, so that the problem became a global concern. There is some recent research on biological or chemical remediation techniques, but efforts seem insufficient in comparison to the enormous impact of the pesticide. In regard to Endosulfan chemical analyses, during the past 15 years immunochemical hapten-based analysis techniques have been investigated as alternatives to the instrumental chromatographic methods.

Palabras clave : Endosulfan; haptenes; endosulfan immunochemical analysis; endosulfan environmental problematic; endosulfan international regulations; endosulfan current normativity; instrumental methods for the analysis.
