Leaching test analytical techniques

As an example of such an integrated approach, a case study is reported in which a soil from a former smelter and scrapyard was investigated. The case study demonstrates the importance of an investigative approach that employs a range of analytical techniques to evaluate toxic metal distribution and mobility. It showed that total element analyses of separated size fractions, characterization leaching tests such as sequential extractions, and detailed electron microscope analysis can provide complementary information on the location and chemistry of toxic metals in soils.
