Resumo
Interações entre íon metálicos e pesticidas fornecem informações adicionais quanto a utilização de compostos químicos em solos e meios aquosos. Essa interação tende a gerar substâncias nocivas para a saúde humana e ao próprio ambiente, sobretudo em áreas do campo onde a presente ação traz malefícios ao alimento cultivado. O crescimento recente no número de pesticidas liberados pelo Ministério da Agricultura fez com que a remediação ambiental fosse ainda mais dificultada, tendo como base a liberação de pesticidas aplicados em outras regiões do mundo. Com isso, tornou-se relevante a investigação de técnicas eficazes e ágeis para a averiguação destas espécies em diferentes amostras. Dessa forma, objetivou-se com este estudo analisar e discutir os principais métodos utilizados para a avaliação da interação entre íons metálicos e moléculas de pesticidas no meio ambiente. Aplicou-se, portanto, uma revisão bibliográfica por meio de uma pesquisa de natureza qualitativa na base de dados do Web of Science, pois é uma das bases de de dados mais utilizadas, em um período de 2000 a 2022. Quanto aos resultados, observou-se que as técnicas espectroscópicas são as mais utilizada, por serem eficientes tanto em investigações no solo quanto em meios aquáticos. Além disso, concluiu-se que os meios aquosos são as amostras mais estudadas sobre a interação de pesticidas e metais, em razão dos efeitos causados às plantas aquáticas. Métodos eletroanalíticos também foram contemplados nesta busca como uma possibilidade de avaliação de baixo custo.
Interactions between metal ions and pesticides provide additional information regarding the utilization of chemical compounds in soils and aqueous media. This interaction tends to generate harmful substances for human health and the environment itself, especially in areas of the field where the present action brings harm to the food grown. The recent growth in the number of pesticides released by the Ministry of Agriculture has made environmental remediation even more difficult, based on the release of pesticides applied in other regions of the world. As a result, it became relevant to investigate effective and agile techniques for investigating these species in different samples. Thus, the objective of this study was to analyze and discuss the main methods used to evaluate the interaction between metal ions and pesticide molecules in the environment. Therefore, a bibliographic review was applied through a qualitative research in the Web of Science database., as it is one of the most used databases, in a period from 2000 to 2022. As for the results, it was observed that spectroscopic techniques are the most used because they are efficient both in soil investigations and in aquatic environments. In addition, it was concluded that aqueous media are the most studied samples on the interaction of pesticides and metals, due to the effect caused to aquatic plants. Electroanalytical methods were also contemplated in this search as a possibility of low-cost evaluation.
