ActiveSoil and sediment - Sequential extraction procedure of speciation of 13 trace elements
土壤和沉积物 13个微量元素形态顺序提取程序
Application Summary AI generated
This standard specifies a sequential extraction procedure for determining the chemical speciation of 13 trace elements (such as copper, lead, zinc, and cadmium) in soil and sediment samples. It is applied in environmental monitoring, geochemical surveys, and mining impact assessments to evaluate the mobility, bioavailability, and potential ecological risk of heavy metals in contaminated land or aquatic sediments. The procedure is used by laboratories conducting soil pollution investigations or remediation feasibility studies.
