Analytical Procedures For The Analysis Of Heavy Metals In Contaminated Soils
Published 1995 · Environmental Science
Heavy metals are held in soils by a number of mechanisms, the measurement of which is usually defined by the extraction procedure. The system is even more complex in contaminated soils, where the metal may be present as relatively insoluble and immobile inorganic or organic forms. The setting of threshold or trigger values for heavy metals in contaminated soils has usually been based on a measurement of total metal. There are three aspects of such measurements which are important to consider.
