The paper contains also information about mobility tests applied to a BCR Certified Reference Material 701, lake sediment. The experimental data proved that NFX31 – 120/1-92 (EDTA and NH4OAc solution) can be successfully used for estimate the release of metallic elements from terrestrial sediments polluted by mining activities.en-USExtraction methodSedimentMobile fractionMining siteBioavailabilityLakeArticle
