在保加利亚收集了26个受人为源（燃煤电厂、交通排放、铅/锌和铁工厂）影响的地点的表层土壤和洋甘菊植物样本。采用欧盟标准、测量和测试计划（BCR）提出的提取方案，对可动员（0.11 mol/L乙酸提取）和植物可利用（0.05 mol/L EDTA提取）金属组分进行了评价。甘菊根、茎和花中镉的积累量与乙酸/EDTA可溶性镉含量及土壤总镉含量呈显著正相关（r = 0.84）。然而，发现铅的吸收仅与edta可溶性土壤组分中的含量显著相关（r > 0.82）。结果表明，EDTA单次土壤提取是快速测定污染土壤中甘菊植物对Cd和Pb潜在有效性的有效方法。
ABSTRACT Surface soil and chamomile plant samples from 26 locations affected by several anthropogenic sources (coal-burning power plant, traffic emissions, lead/zinc and iron factories) were collected in Bulgaria. The mobilizable (extracted by 0.11 mol/L acetic acid) and the phytoavailable (extracted by 0.05 mol/L EDTA) metal fractions were evaluated using the extraction protocols proposed by the Standards, Measurements and Testing Programme of the European Union (BCR). Cadmium accumulation in chamomile roots, stems and flowers correlated well with acetic acid/EDTA soluble Cd as well as with the total soil cadmium (r > 0.84). However, lead uptake was found to correlate significantly only with its content in the EDTA-soluble soil fraction (r > 0.82). The results reveal that single soil extraction with EDTA is an appropriate procedure for quick estimation of potential availability of Cd and Pb to chamomile plants from polluted soils.
