Table 5.2.3 Approximate rating scale of soil pollution hazard according to (Zc)
Pollution class Value Zc Changes in human health in pollution focus
Permissible Less than 16
Moderately hazardous 16-32 The increase in general morbidity
Hazardous 32-128
Extremely hazardous Nore than 128
The lowest level of child morbidity and minimal incidence of functional
abnormalities
The increase in general morbidity, the number of sickly children,
children with chronic diseases, impaired functional status of the
cardiovascular system
The increase in child morbidity, impaired reproductive function of women
(ILelichenie toxicosis of pregnancy, the number of premature births,
stillbirths, infant malnutrition)
The total pollution index Zc was calculated by 9 contamination parameters: manganese, zinc,
copper, nickel, cobalt, lead, cadmium, chrome and mercury. The concentrations of heavy metals in
the Far North regions (Taimyr Peninsula and Spitsbergen Archipelago) were used as background
values according to long-term observation (Arctic Pollution Issues, AMAP Assessment Report,
Norway, Oslo, Arctic Monitoring and Assessment Programme (AMAP), 1998) given in Table 5.3-
4).

Evaluation of chemical contamination of soils according to international standards is performed by
comparing the obtained values of the content of controlled parameters with the values of PC and IL
(SP 11-102-97, Appendix B).Permissible concentration (PC) is defined as an estimated set
maximum concentration of substance polluting ground that does not cause adverse direct or indirect
impact on the environment and human health.
Soil containing contaminants less than DC can be attributed according to the Russian classification
to the category of clean acceptably polluted, with the contents higher than PC and less than the
intervention level that correspond to the category of pollution from moderately polluted to
hazardously polluted.
When the concentrations of pollutants exceeding the intervention level (IL) are detected, soils are
considered to be hazardously contaminated and referred to the third and a higher class of risks of
