Assessment of soil contamination is primarily based on the analysis of single samples. The representativeness of an analytical sample (the amount of material that will be used for the analysis) which has to be taken from the original sample, can be the cause of large errors. Such errors, resulting in large values for variance and bad analytical reproducibility, should, and can, be reduced significantly by means of specific sample pretreatment methods.
