Abstract The results of chemical analyses of soils show large variations due to the heterogeneity of the material, differences in pretreatment and analytical methods, and unavoidable random errors. In this article, the analytical aspects in the determination of heavy metals in soils are highlighted. Both within-laboratory and between-laboratory variation must be minimized by validation and standardization procedures, respectively, in order to keep the variations resulting from the analytical procedure at an acceptably low level. Even then, the best results will show uncertainties of 5–20%, an issue that should be recognized by governmental and legal bodies.
