Study of Heavy Metals in the Soils of Two Localities in Dolj County

Abstract The study was conducted in two neighboring localities located in the northern county of Dolj, namely Murgasi and Bulzesti. The purpose of the study was twofold: namely, the study of heavy metal loading in order to identify possible pollution areas and to know the soil content of these localities in heavy metals in order to be able to give the verdict on the use of sludge from Craiova wastewater treatment plant as fertilizer on these soils. In order to determine the suitability of sewage sludge from the Craiova wastewater treatment plant as a fertilizer, physical and chemical properties and heavy metal content of the soils in these areas were analysed, as well as the chemical composition of sludge, according to Order 344/2004 of the Ministry of Environment and Water Management of Romania, respectively 13 physical and chemical parameters of the soils in these localities and the chemical composition of the sludge and respectively the quantity of heavy metals to be introduced annually into the soil by using it.
