To study the spatial distribution characteristics of 10 heavy metals(As, Hg, Mo, Cd, Cr, Zn, Cu, Mn, Pb, Ti) in the soil of Dexing area, Semi-variance function is used to quantitatively describe the structural features of the spatial distribution and map the content distribution. The analysis shows, in addition to cadmium and lead, other elements fit relatively well, which reflects a good spatial...
The influence of various concentrations of salts of lead (II), copper (II), manganese (II), cobalt (II), molybdenum (IV) and iron (III) upon the soil dehydrogenase has been studied. Ecological areas featuring the contamination degree to which the studied soil environment had been exposed have been determined. Particular attention has been paid to high heavy metal doses causing significant disturbance...
Lead, cadmium, zinc, manganese, chromium, cobalt, copper, and molybdenum concentrations were measured in 50 samples of placenta tissues. The samples came from Tychy in the Upper Silesian Industrial District (Poland), where the population is exposed to enormously increased levels of heavy metals. GFAAS technique was used. Various methods of ashing samples were examined. Wet ashing under pressure in...
