Determinação de Contaminantes Emergentes em Amostras de Água no Brasil por Técnicas Voltamétricas: Revisão da Literatura

Resumo

The presence of emerging contaminants (ECs) in aquatic matrices is of great concern due to the environmental impacts they can cause and their harmful effects which although unknown, they can pose risks to human health and organisms from different ecosystems. The use of analytical techniques is essential in the study of these contaminants as they make it possible to identify, characterize, determine, and obtain important data for the monitoring of these compounds. Voltammetric techniques are alternative analytical tools that have the advantages of low cost, high sensitivity, good selectivity, short analysis time, among others. The present work brings a bibliographic review on the research that addressed the determination of emerging contaminants in water samples from different Brazilian matrices (surface, underground, residual, and supply water) by voltammetric techniques between the years 2000 and 2020. From the analysis of the articles, an assessment was made of the viability of the different voltammetric techniques for determining ECs in water samples, to assist in the monitoring of these compounds in the environment and by the information obtained, to promote the adoption of control measures of contamination and the inclusion of these contaminants in environmental legislation.
