Quantification of toxic organic pollutants by electrochemical methods

Contamination of water bodies by toxic organic pollutants and its faster and more accurate quantification is critical to the safe monitoring and controlling of water-borne diseases. Toxic organic pollutants have been found to be inimical to human health and responsible for cancer, infertility, and other degenerative diseases affecting the kidney and liver. Electrochemical techniques provide a versatile tool for monitoring these toxic organic pollutants in water bodies, even at a trace level, without elaborate sample preparation as required in the conventional method of analysis. Scientists have developed different electrochemical methods for identifying and quantifying these persistent organic pollutants to monitor and control them. The objective of this article is to offer a comprehensive overview of the different methodologies for quantifying toxic organic pollutants using electrochemical methods. Advancement in material science, which has led to better quantifying trace toxic organic pollutants, is also discussed. Finally, recent applications and future trends in quantifying toxic organic pollutants driven by advancements in materials development are enumerated.
