Blood lead levels in children living close to the antimony and lead mining-milling-smelting complex in Serbia
Objective of this cross-sectional study was to determine blood lead concentrations in children, living in the vicinity of the Zajača lead-antimony mining-milling-smelting complex. Other aims were to compare blood lead levels (BLLs) of exposed children to those of partially exposed and non-exposed, and correlate values of BLLs from two consecutive sampling series in 2012 and 2013. Performed laboratory method was atomic absorption spectrometry (AAS). Statistical significance of comparisons was tested by univariate methods and non-parametric tests for the attributable variables: Hi-square test, proportion test. In the case of non-parametric variables, following tests were used: Kolmogorov-Smirnov Z test for testing distribution's normality; ANOVA for the normal distribution, while a Kruskal Wallis Test was used in cases without normal distribution. 142 participants were tested on lead in blood: exposed, partially exposed, and non-exposed). Mean BLLs in children living at less than 1 km from the smelter was 18.98 µg/dl , at first test series, and 12.21 µg/dl, in the second round. For those living further than 3 km mean BLLs at first series was 8.30, and at the second series it was 5.85). Blood lead concentrations in children from Zajača are highest.
