原始语种摘要: ABSTRACT(#br)Different chemical methods have been developed to evaluate the bioavailable fraction of the trace metals. Due to the lack of a universal method for analysis of the bioavailable metal fractions, due to the differences in sediment characteristics, it is necessary to validate an appropriate chemical method for assessing the available fraction of trace metals. For this propose, in this study, different chemical extraction methods including extraction with HCl and desorption test as a single reagent leaching test as well as geochemical fractions method have been evaluated. Bushehr coastal sediments in the Persian Gulf coasts have been selected for this purpose. To validate the efficacy of these methods, a gastropod species ( Trochus erithreus ), as a bioindicator, has been...
