Illegal mining in the Orinoco River: challenging governance at the border

The minerals that are mainly extracted are gold and coltan, almost always for exportation purposes. The growth of gold mining in the region of the Orinoco Colombia in the last fifteen years has created a problem of public health due to several factors such as the use of mercury in the gold amalgamation process, ecosystem pollution and exposure of the population of the region. The results indicate a precarious work environment and lack of knowledge of ecological risk. The values ​​of blood mercury in mining ranged from 6.9 - 168 μg/L and between individuals indirectly exposed from 17.7 to 100.8 μg/L, while in the hair of the miners did so between 3 to 89.2 μg/L and indirectly exposed between 2.8 to 48.7 μg/L
