EMISSION IMPACT ASSESSMENT FROM TURCENI POWER PLANT ON THE HEAVY METAL POLLUTION OF THE SOIL
Abstract
For evaluation environmental impact of emissions resulting from the combustion of lignite for thermoenergetic purposes the sampling was done in order to follow the evolution of heavy metal concentration of solid fuel use, the ash from the filter within the ash and slag heap, the soil adjacent to potential sources of heavy metal emissions power plant and landfill. This paper presents the methodology of sampling and heavy metal pollution level Zn, Cu, Mn, Pb, Ni, Cd, Co, Hg in the area of coal power plants (CET Turceni) in 2010. In this sense, quantitative analysis of metals in ash, soil and plant products, was achieved by modern instrumental techniques Atomic absorption spectrometry (AAS). To assess the time evolution of the level of heavy metals in the soil are presented and the results of physico-chemical and biological weapons made in 1997, 2000, 2010. Soil of the coal-fired thermal power plant is a ground with anthropogenic load of heavy metals, especially Cu, Pb, Ni Cd, Zn whose range values exceed the background content and even the limit for sensitive soils (Pb).
