Quantificação de mercúrio em amostras de suínos de produção (Sus scrofa) em diferentes regiões brasileiras e animais selagens (atropelados) na BR 262

Abstract

The aim of this work was to quantify mercury (Hg) in hair samples of various species in Brazil. 169 samples of fur from species that make up the wild fauna and farm pigs were quantified, from different regions (Goiás, Minas Gerais, Paraná and Mato Grosso do Sul). These were subjected to chemical analysis and reading processes through the atomic absorption spectrophotometer. The two groups with the highest amount of Hg were wild animals from Mato Grosso do Sul and pigs from site 2 of Minas Gerais. Statistically significant results, however, according to the literature are acceptable concentrations found in the organism of animals. Diagnosis of the presence of mercury both in wild fauna and production area are essential because they directly impact on human health. Wild animals, although not part of human food, should be free of toxic metal indices, especially in conservation areas. However, the presence of these metals suggests possible environmental pollution in places that should be protected.
