title: Methods for chemical analysis of contaminated soil samples--tests of their reproducibility between Nordic laboratories.
abstract: In an effort to develop common analytical methods for contaminated soil samples the Environmental Authorities of the Nordic countries have, together with Nordtest, published the report Nordic Guidelines for Chemical Analysis of Contaminated Soil Samples. The aim of these guidelines has been to describe analytical methods which could be accepted in all the Nordic countries and in that way contribute to reducing the variation in the analytical results between laboratories. The methods covered, reflects environmental concerns and priorities in the Nordic countries for now, i.e. heavy metals, chlorophenols, creosote, volatile organic compounds, PCB, THC and PAH. The repeatability and reproducibility of the guideline methods were determined in a Nordic inter-laboratory test in 1996, and the results showed some variations. The analytical methods and the results from the inter-laboratory tests are given for heavy metals, chlorophenols, creosote, volatile organic compounds and PCB.
