The application of pHstat leaching tests to assess the pH-dependent release of trace metals from soils, sediments and waste materials KU Leuven
pH is one of the key parameters that determines heavy metal mobility in soils, sediments andwaste materials. In many respects leaching behaviour as reflected by the pHstat leaching tests provide a better means of assessing environmental impact than analysis of total elemental composition. This paper discusses the use of pHstat leaching tests as a tool to assess the potential mobilisation of trace metals from soils, sediments and waste materials. ...
