Assessment of human exposure to environmental heavy metals in soils and bryophytes of the central region of Portugal

摘要: This study intends to identify the spatial patterns of variation for some metals and metalloids, in soils mosses, central region Portugal. The purposes were: (i) relationships amongst five elements (Cu, Pb, Zn, Cr As) three different media (topsoil, bottom soil bryophytes) with site-specific characteristics, using Multiple Correspondence Analysis; (ii) define associations identified by Analysis Variography Ordinary Kriging; (iii) assess atmospheric deposition as a source heavy topsoil crossing results biomonitors. indicated relatively low metal concentrations mosses. Some dissociations were identified. are distinct. There is evidence that characteristics control distribution elements. areas w...
