Resumo: Tests for bioaccessibility are useful in human health risk assessment. No research data with the objective of determining bioaccessible arsenic (As) in areas affected by gold mining and smelting activities have been published so far in Brazil. Samples were collected from four areas: a private natural land reserve of Cerrado; mine tailings; overburden; and refuse from gold smelting of a mining company in Paracatu, Minas Gerais. The total, bioaccessible and Mehlich-1-extractable As levels were determined. Based on the reproducibility and the accuracy/precision of the in vitro gastrointestinal (IVG) determination method of bioaccessible As in the reference material NIST 2710, it was concluded that this procedure is adequate to determine bioaccessible As in soil and tailing samples from gold mining areas in Brazil. All samples from the studied mining area contained low percentages of bioaccessible As.

Dados de pesquisa com o objetivo de determinar o arsênio (As) bioacessível em áreas alteradas por atividades de mineração e beneficiamento de ouro são inéditos no Brasil. Em amostras coletadas em quatro áreas (RPPN, B2, estéril e rejeito) de uma mineradora em Paracatu, Minas Gerais, foram determinados os teores de As total, bioacessível e extraído por Mehlich-1. Com base na replicabilidade e na acurácia/precisão do protocolo in vitro gastrointestinal (IVG) para determinação de As bioacessível no material de referência NIST 2710, pode-se afirmar que o protocolo é adequado para a determinação de As bioacessível em amostras de solos/rejeitos de áreas de mineração de ouro situadas no Brasil. Todas as amostras da área de mineração estudada apresentaram baixos percentuais de As bioacessível.Sociedade Brasileira de Ciência do Solo2020-07-30T15:00:08Z2020-07-30T15:00:08Z2012info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfONO, F.
