Human societies have, in all ages, modified the original form of metals and metalloids in
their living environment for their survival and technical development. In many cases, these …

The authors review selected protocols of sequential selective extraction procedure that are
used to characterize the geochemical distribution of heavy metals in soils, wastes, and …

Runoff quantity and quality from a 248m2 extensive green roof and a control were compared
in Connecticut using a paired watershed study. Weekly and individual rain storm samples of …

The concentration and distribution of As, Cd, Cr, Cu, Mn, Pb, Zn and Fe were determined to
estimate soil contamination in freshwater wetlands (S1 and S2), brackish wetlands (S3) and …

The bioavailability and mobility of heavy metals in soils is dependent upon redistribution
processes between solution and solid phases and among solid-phase components. This …

Sequential extraction procedure was applied to assess the dynamics of solid-phase
transformation of added Cu, Pb, Cd, and Hg in a typical Chinese paddy soil incubated under …

The vadose zone (often called the unsaturated zone) is commonly defined as the geologic
media spanning from the land surface to the groundwater table of the first unconfined aquifer …
