The data about the persistent organic substances (Dutch list), from 560 soil samples have been evaluated. They include mono- and polyaromatic hydrocarbons, chlorinated hydrocarbons (PCB, HCB, DDT and metabolites), styrene and oil products. The data have been statistically processed within two sets: soil from both anthropogenically affected and immission-free regions (491 samples), soils from immission-free regions Sumava Mountains and Czech-Moravian Highlands (96 samples). The upper level of variability of the content of single compounds has been assessed. The exceeding of this reference value indicates the increased inputs in soils. The concept of this approach is approved by the gained results as compared with the similar reference values of German authors. They have no ecotoxicological relevance. Czech contamination limits differ both from the old new Dutch standards, supported by ecotoxicological research.
