| Abstract |
Sequential extraction procedures consist of subjecting a given sediment sample to a series of increasingly strong reagents under specified conditions. The most carefully designed and most often followed method is that of Tessier et al. (1979). These procedures, which were conceived as an attempt to determine the particulate speciation of trade elements and radionuclides, have serious limitations. Despite several studies demonstrating the instability of published methods for sequential extraction to determine chemical entities definable by more than the analytical method itself. The purpose of the comment is to discourage the expanding uncritical use of sequential extractions for measuring the particulate speciation of trade elements.
