Aqui é apresentado um método para extrair microplásticos do solo e identificar seus tipos de polímeros. O método foi otimizado para execução, aplicabilidade e custo-benefício. Ele estabelece uma base científica para padronizar o método analítico para identificar microplásticos em solos.
Este protocolo descreve a amostragem convencional de microplásticos e a amostra analisada do solo. O método inclui sete partes. Eles são amostragem e preparação do solo, flotação por densidade, digestão de impurezas, coloração, filtração a vácuo, observação morfológica e identificação de polímeros.
Aqui, apresentamos dois processos analíticos diferentes das duas etapas finais, que podem ser realizados independentemente um do outro, dependendo da disponibilidade do instrumento. Coletar uma amostra representativa do solo usando um método de amostragem de cinco pontos de maneira dupla em uma área estável. Use uma broca de solo de aço inoxidável de 30 centímetros para coleta.
