This study compares Cd extractability using 13 commonly used extraction procedures for 28
soils, varying in composition (0–88% sand; 0.9–12.8% organic matter; pH 5.2–8.2) and …

Various cadmium-sorbed and cadmium-coprecipitated “soil phases” were prepared and
sequentially extracted using the five-step method of Tessier et al. Reagent selectivity was …

Extraction efficiency, reagent specificity and selectivity, and element redistribution are
potential problems with trace element fractionation by sequential extraction. As part of a …

This study aimed at evaluating the selectivity of different extractants—and thus the efficiency
of various extraction schemes—used to assess the Cd speciation in the soil of the Swiss …

Potential risks for human health and adverse effects on soil quality caused by accumulation
of cadmium (Cd) in soil at concentrations around or exceeding current European Union (EU) …

A new soil test procedure using 1M NH4Cl was developed for the extraction of plant‐
available cadmium (Cd) from soils. Five grams of soil is weighed into a 50‐mL polyethylene …

The suitability of several extractants was tested for assessing the plant-available cadmium
(Cd) in a few selected soils of South Australia. The amount of Cd extracted by 7 extractants …

Although total heavy metal contents of soil are often used to express the degree of
contamination, they are of little value to judge environmental effects. The main objective of …

Various extraction procedures were employed for measuring extractable concentrations of
potential toxic elements in soil. The extractability of Cd, Cu, Pb and Zn in four contaminated …

Determination of various chemical forms of a metal in soils is important to evaluate its
mobility and bioavailability. Little is known on the chemistry of Cd species of variable charge …
