THE USE OF SEQUENTIAL EXTRACTION PROCEDURES FOR HEAVY METAL SPECIATION IN SEDIMENT. Metals accumulation in sediments from both natural and anthropogenic sources occurs in the same way, making it difficult to identify and determine the origin of heavy metals present in the sediments. Moreover, the total concentration of metals often does not accurately represent their characteristics and toxicity. In order to overcome the mentioned obstacles, it is necessary to evaluate the environment effect. Single extraction is thus used generally to provide a rapid evaluation of the exchangeable metal fraction in sediments. However, complicated sequential extraction procedures are used to provide more detailed information regarding different metal phase associations.

Various single extractants (EDTA, DTPA, CaCl<sub>2</sub>, NaNO<sub>3</sub> and NH<sub>4</sub>NO<sub>3</sub>) and the first step of Community Bureau of Reference (BCR1) method were used to evaluate the immobilization of Cd in contaminated acidic paddy soil by different amendments. The extractability of Cd in amended soil changed in the following order: EDTA &asymp; BCR1 &gt; DTPA &gt; NH<sub>4</sub>NO<sub>3</sub> &asymp; CaCl<sub>2</sub> &gt; NaNO<sub>3</sub>. A simple correlation analysis indicated that the BCR1, CaCl<sub>2</sub>, NH<sub>4</sub>NO<sub>3</sub>, and NaNO<sub>3</sub> methods are the best suited methods for predicting changes in the phytoavailability to rice of Cd in soil (r = 0.680 to 0.828, P &lt; 0.001), followed by the DTPA extraction procedure (r = 0.543 to 0.666, P &lt; 0.01). However, non-significant correlations were observed between soil EDTA-extractable Cd and Cd accumulated in rice. Accordingly, the BCR1, CaCl<sub>2</sub>, NH<sub>4</sub>NO<sub>3</sub>, and NaNO<sub>3</sub> extraction procedures are recommended for evaluating the immobilization of Cd in contaminated acidic paddy soil. &nbsp;
