Ai. Obukhov et Aa. Popova, SEASONAL DYNAMICS AND SPATIAL VARIABILITY OF THE HEAVY-METAL CONTENT OF SOILS AND GROUNDWATER, Eurasian soil science, 24(9), 1992, pp. 71-82
Against the background of significant spatial variability (from 30 to
90 percent for different heavy metals (HM)), the seasonal dynamics of
the content of mobile forms of Zn, Fe, Mn, Cu, Pb, and Cd compounds in
cultivated Sod-Podzolic soils and concentrations of Fe, Mn, and Zn in
groundwater is reliably detected (P = 0.95). The factors which affect
the seasonal dynamics of HM are investigated. Mechanisms which regula
te the HM concentration in groundwater are studied.
