RESUMO:

The search and exploitation of precious metals is a highly developed economic field in Brazil, which is why the country is well known for being one of the largest exporters of this type of raw material. And in the northern region of the country it was no different. In Porto Velho – RO, more precisely in the area where the Madeira River is located, for decades it has suffered so much from the extraction of gold ore, whether legal or illegal. It happens that, regardless of the way in which mineral exploration occurs, the negative impacts caused in nature, mainly with the release of tailings from the exploration of gold, especially mercury (Hg). Therefore, literary researches were adopted that for the deepening on the subject, as well as it was possible to perceive that, more recent surveys on the distribution of Hg in the region of the Madeira River basin identified the existence of processes of bioaccumulation and biomagnification in the aquatic biota, although current data indicate that levels are within normal ranges. The occurrence of contamination by chemical compounds, such as Hg, is one of the main problems caused by the exploration of gold, given that this type of metal is widely used to promote the separation of mixtures and catalyze the reactions. In the social sphere, it is seen that, in addition to the direct and indirect generation of jobs in the places where gold is explored, many of the other minerals obtained are used in the most diverse areas, including civil construction. The point is that, even in cases where the exploratory activity is carried out in a legal way, it is capable of causing major impacts on the environment, such as the suppression of vegetation and soil exposure to erosive processes. Thus, when this type of mineral exploration is carried out without proper supervision by the competent bodies, and within environmental protection areas, the damage naturally caused tends to take on increasing proportions, thus compromising local biodiversity.
