Abstract
The polluting activity carried out by the coal exploitation in Roşiuţa coal pit has effects on the environment and the main pollution sources of the atmosphere are: suspended powders, particulate matter and burning gases. The pollutants contain substances with different degrees of toxicity. Through the measurements performed “in situ”, for the dust concentration at different points, it was found that the indices of the maximum concentration (MC-mg/m3/air), on the mining areas, were according to the legislation in force. At some points, the dust concentration is higher, but as the distance increases, the pollution is no longer felt, so it can be noticed that the lignite exploitation has a local influence.
