Determinação eletroanalítica do herbicida Atrazina : uma revisão bibliográfica

Abstract

The use of pesticides (chemical substances with the purpose of achieving the elimination and/or control of pests in environments where these are not beneficial) has shown considerable growth in recent decades. However, during application on crops, a part of these pesticides is not fully used, and the rest, not used, is what we call residue, which can be spread through the environment, polluting natural bodies of water, soil, air and food consequently. Triazines are used as herbicides in agriculture, but their indiscriminate and uncritical use have brought and are bringing very serious problems to the environment and human health. Monitoring of these substances is therefore necessary to measure their impact, electroanalysis technology has had a positive outlook for determining herbicides, involving a variety of working electrode materials, which helps to improve the selectivity of the determination. The present monograph work aimed to carry out a Bibliographic Review of electroanalytical techniques in the analysis and determination of the herbicide atrazine, belonging to the class of triazines in various environments, such as natural waters, soil and food.
