The aim of this research was the investigation of the effectiveness of several extractants as possible assessment of pseudo-total As, Pb and Cu concentrations in moderately contaminated soils of Central Greece. In soils of 3 different land uses (forest, agricultural and industrial), various extraction procedures were performed using simple and low-cost extraction solutions, i.e. inorganic acids (HCl and H₃PO₄), salts (NH₄NO₃ and CH₃COONH₄), organic chelating agents (as ethylenediaminetetraacetic acid (EDTA) and diethylenetriaminepentaacetic acid (DTPA)) and an alkaline agent (NaOH). The findings were reported as percentages to their pseudo-total concentrations obtained using Aqua Regia. The species of As (III), As (V) and total As(T) were extracted. Higher percentages of As concentrations were extracted using H₃PO₄ concluding that this may be the most effective of the extractants used. On the other hand, the percentages of the EDTA-extracted Pb and Cu, in forest soils with high organic matter content, were the highest. In forest soils, also, satisfactory correlations between EDTA-extracted Pb and Cu versus their pseudo-total content were observed. Finally, significant correlations among As, Pb and Cu concentrations in some soil extracts and soil physicochemical parameters were obtained, suggesting that the extractability of As, Pb and Cu may depend upon soil characteristics in the study area.

这项研究的目的是调查几种萃取剂作为评估希腊中部受中等污染土壤中砷，铅和铜的伪总浓度的有效性。在3种不同土地用途（森林，农业和工业）的土壤中，使用简单且低成本的提取溶液进行了多种提取程序，即无机酸（HCl和H ₃ PO ₄），盐（NH ₄ NO ₃和CH ₃ COONH ₄），有机螯合剂（如乙二胺四乙酸（EDTA）和二亚乙基三胺五乙酸（DTPA））和碱性试剂（NaOH）。报告的结果以使用Aqua Regia获得的伪总浓度的百分比报告。提取了砷（III），砷（V）和总砷（T）的种类。使用H ₃ PO ₄提取更高百分比的As浓度结论这可能是最有效的萃取剂。另一方面，在高有机质含量的森林土壤中，EDTA萃取的Pb和Cu的百分比最高。在森林土壤中，也观察到EDTA萃取的Pb和Cu与它们的假总含量之间具有令人满意的相关性。最后，获得了一些土壤提取物中As，Pb和Cu的浓度与土壤理化参数之间的显着相关性，表明As，Pb和Cu的可提取性可能取决于研究区域的土壤特性。
