PTMs Partitioning Between Soil Geochemical Phases

PTMs Partitioning Between Soil Geochemical Phases [Pg.191]

When PTMs concentration is well in excess of normal soil content, extraction method validation, in terms of direct correlation between soil extractable contents and plant contents, is less easy to achieve. In these cases, it may be adequate to develop an operational estimate of the mobile and potentially mobile metal species rather than plant-available species. It is necessary to analyse metal partitioning between such fractions as exchangeable sites, organic matter and minerals of varying solubility. [Pg.191]
