Heavy Metals in Dust Deposition in the Vicinity of Coal Ash Disposal Site Divkovici II

DD (Dust deposition) was monitored over a 6-month period (April to September, 2011) at four sites located in villages near CADDII (coal ash disposal site Divkovici II), one inside recultivated CADDI (coal ash disposal site Divkovici I) and at one in the middle of forest barrier as control site. The main aim of this paper is to perform monitoring of air dust pollution in the area by measuring of dust deposition, different metals associated with it, and probable adverse effects on human health. Concentrations of metals were measured by using Perkin-Elmer model Inductively Coupled Plasma and statistically evaluated with SPSS 17.0 statistical program. There was a correlation between some metals (Mn, Mo and Pb) and DD distribution. The daily limit values for concentration of DD proposed by national "Regulations on air quality" (200 mg/m 2 d average annual value and 350 mg/m 2 d high value) exceed at three measuring sites. The average maximum content of DD was 684.8 mg/m 2 d downwind of CADDII, and the average minimum was 46.8 mg/m 2 d at measuring site F. Concentrations of pollutants hazardous to the environment as Ni, Cr, Cu, Mo, Mn and Pb vary from one site to another.
