Presença de mercúrio em vegetais comestíveis produzidos próximos a mineração artesanal em pequena escala de ouro

Abstract

Mercury (Hg) is one of the most harmful pollutants to the environment, and can present toxic levels in water, soil or atmosphere. It is recognized as a global concern, above all, for its releases in gold mining areas. These things, qualities, qualities and safety can be consumed by commercial products, especially products consumed by safety. How to absorb and accumulate general metals in your biomass, essentially, through plants, through plant planting, and generally accumulate from the soil. The morphology of Hg plants depends on many factors such as plant specifics, including morphology and physiology, in addition to properties such as soil type factors or time of exposure to the soil. Identify yourself as a source of protection for the health of the Amazon commercially is fundamental for the protection of public health, mainly for the protection of public health, especially in susceptible to this source of food as the south of the Amazon. Thus, this quantified the concentration of cassava crops in study areas of family farming in the south of the Amazon, both in properties close to the activities Artisanal and Small-Scale Gold Mining (ASGM), allowing to assess the existence of risks to the health of the population that consumes this food due to exposure to Hg. Samples of cassava molds were collected, being located in the pattern of Hg present in the roots, in addition to the soil surrounding the rhizome. The results indicate that the Hg contents in the leaves and upper roots of cassava were in the area close to the gold mining. Whether cassava presented the position of potential use of Hg areas close to ASGM. It is also observed that based on the consumption of cassava and cassava flour are registered trademarks by the population of the region, as it can also be considered a health risk, however, in countries or that communities are cassava food and cassava leaves. subsistence and, therefore, consumed in greater proportions, it is warned that there may be a risk to health due to production in areas close to ASGM. Monitoring food production in areas neighboring ASGMs is essential to guarantee food security in these locations, minimizing risks to the health of the population
