Impactos ambientais da mineração no estado de São Paulo
MetadataShow full item record
Generally, mining causes significant impact over the environment, since this activity often involves suppression of vegetation, soil exposure and erosion resulting in important changes in the quantity and quality of surface and ground-waters and in air pollution, among other negative effects. The prevention and mitigation of these impacts in the State of Sao Paulo are made through the environmental licensing. Another way of environmental management includes programs like mining and environmental zoning and regional mining director plans. But there is clear dissociation between the actions effectively taken and those recommended in the projects, limiting the recovery of degraded areas to measures that only attenuate the visual impact. this paper presents considerations on the subject and challenges of the industry to adapt to the Federal Constitution and the National Policy on Environment.
