量化土壤中的重金属和微量金属污染可能是困难的，需要使用冗长和复杂的提取程序，这可能会给出可靠的结果，也可能不会。在出版的许多程序中，一些程序设计为在特定参数范围内操作，而另一些程序则设计为更广泛的应用。大多数程序自开始以来都进行了修改，这造成了在特定情况下哪种程序是最可接受的含糊不清之处。在这项研究中，对Tessier、社区参考局(BCR)、Short、Galán和加拿大地质学会(GCS)的程序进行了审查，以澄清每种程序的优点和局限性。对Tessier、BCR和GCS程序的修改也进行了检查。这些程序的有效性是通过观察每个程序中使用的土壤、顺序提取的限制、应用和未来来解决的。
Quantification of heavy and trace metal contamination in soil can be arduous, requiring the use of lengthy and intricate extraction procedures which may or may not give reliable results. Of the many procedures in publication, some are designed to operate within specific parameters while others are designed for more broad application. Most procedures have been modified since their inception which creates ambiguity as to which procedure is most acceptable in a given situation. For this study, the Tessier, Community Bureau of Reference (BCR), Short, Galán, and Geological Society of Canada (GCS) procedures were examined to clarify benefits and limitations of each. Modifications of the Tessier, BCR, and GCS procedures were also examined. The efficacy of these procedures is addressed by looking at the soils used in each procedure, the limitations, applications, and future of sequential extraction.
