Environmental issues induced by the sterile dump from Husnicioara district Mehedinţi

Abstract

The paper presents the pedological and agrochemical features of the sterile dump Husnicioara, District Mehedinti that has a surface of 190 ha. There are presented the po lluting effects of the sterile dump Husnicioara on the environment. The air pollution is done by two ways: by solid suspension emanation; by gas emanation. The air pollution that is caused by dust emissions, especially due to car transport and conveyer transport is a major problem fro the neighborhood villages to mines. The Romanian standard abou the quality of the air for dust is 0.5 mg/m3 is overpasses by 10 times near coal deposits, along the way between mine and dump. Next to the emanation sources there were determined emanations of 4.0-5.7 mg/m3 , atmospheric powders being overpasses by 8-18 times the MAL (0.5 mg/m3 ). At 100-150 m distance, the values were under this limit.
