MONITORING OF LEAD, COPPER AND CADMIUM CONTAMINATION LEVEL OF SOIL FROM ZLATNA REGION ROMANIA

摘要

Industrial activities as mining and smelting of metalliferous ores are the main sources of soil contamination with heavy metals. This kind of pollution has a negative effect on plant growth and serious consequences on human health. In this paper, an overview of soil contamination by heavy metals across Zlatna area, in 2004 and 2012, is presented together with standard values for heavy metals in soil set by the European legislation. The results show a heavy metals content (lead, copper and cadmium) exceeding these limits. In addition, a statistical analysis of data was performed in order to determine the level of heavy metals in the studied area. The results highlighted the necessity of a strategic rehabilitation of Ampoi valley basin, given the fact that in 2004 the activity of copper smelter plant had been stopped.
