摘要: In an area of south-eastern Sweden, very high Pb concentrations in biogeochemical samples (mainly roots stream plants) were detected. Lead mineralization bedrock was found the same area. Meanwhile, crystal glass industries, which emit large amounts into environment are located nearby. It appears necessary to determine whether derived from natural sources or anthropogenic pollution. Geographical information system (GIS) and multivariate analyses applied solving problem. GIS is used for spatial visualization problem, quantitative discrimination. Concentrations seven heavy metals (Co, Cr, Cu, Ni, Pb, V Zn) samples, till, discharge data pollutants industries used. Both by analysis provide evidence that studied mainly come mineralization, not human The methodologies developed this study applicable field environmental geochemistry.
