Within the Central-Western part of Romania, in the Zlatna area, around an industrial complex involved in mining, metallurgical and chemical activities, the environment in general and the soils in particular are polluted due to the acid rains and heavy metals on a surface area of about 55.664 hectares, of which about 68 per cent present a high vulnerability to the impact of these pollution types. The increase of the natural soil acidity up to 3.6-3.9 pH values and of soil loading with heavy metals at content levels exceeding up to 41 (Pb), 11 (Cu), 7 (Zn), 4 (Cd) times the maximum allowable limits contributed to occurrence of soil base depletion, micro-biological activity disturbance, organic matter degradation, soil structure deterioration, sheet and gully erosion, as well as landslides on about 10 per cent of the whole surface area affected by the emissions from the Zlatna factory.
