Risk assessment of mercury in Alta Floresta. Amazon Basin - Brazil
Water, Air, and Soil Pollution, 1997In the last 15 years gold mining activity has been the main source of the mercury (Hg) emissions into the atmosphere in the Amazon Basin. The first phase of gold production takes place in remote areas. In general the second one happens in the local urban area, where the gold is commercialized and sent to the great economic centers. In the last 3 years,

Exposure to Mercury in Pregnant Women from Alta Floresta—Amazon Basin, Brazil
Environmental Research, 2000The region of Alta Floresta in the South of the Amazon basin, close to the Teles Pires River, was one of the main prospecting gold areas in the Amazon Basin until the beginning of the 1990s. The economic growth was accompanied by a considerable increase in the population, due to a massive influx of migrants from the southern region of the country ...

Atmospheric mercury and trace elements in the region of Alta Floresta in the Amazon Basin
Water, Air, and Soil Pollution, 1995In the early 1980’s the Amazon region in the North of Brazil was the scene of the most intense gold rush in the history of Brazil. Metallic mercury (Hg) in gold mining activities is used to amalgamate particulate gold. The other sources of Hg emissions in Amazonian are tailing deposits and biomass burning of tropical forests and savannas.

The effects of land use change on mercury distribution in soils of Alta Floresta, Southern Amazon
Environmental Pollution, 2004This study presents the spatial distribution, degree of contamination and storage capacity of Hg in surface forest and pasture soils from Alta Floresta, Southern Amazon, a significant gold mining site from 1980 to 1996. During that period, average annual gold production was about 6.5 tons, with an estimated Hg annual emission to the environment of ...

Mercury exposure through fish consumption in the urban area of Alta Floresta in the Amazon Basin
Journal of Geochemical Exploration, 1997Abstract This work addresses the mercury exposure scenarios through fish consumption in the urban area of Alta Floresta, by comparing the different patterns of mercury exposure from fish ingestion for different population groups. This study was based on field surveys that could provide background information, such as the characteristics of Hg sources,
