The mechanism of the high concentrations of pesticides in overground air is described. Equivocation and computer program for the pesticides concentration to calculations are worked out.
It is possible to state on the basis of the studies carried out that the system mother-fetus-new-born may be used as the most sensitive biological model to study separate, complex and combined exposure of mammals to chemicals. It was found out that the above mentioned system is highly sensitive and makes it possible to detect a damaging effect to chemicals even on the level of standardized values, while such doses do not produce any negative influence on the adult organism. The proposed system makes it possible to assess material and functional cumulation of chemical substances in the organism of mammals.
Hygienic regulations for the use of coal flotation wastes (CFW) as fertilizers were substantiated by studying the laws of migration of harmful ingredients of CFW from the fertilized soil to the contacting media. The safe doze of CFW to be used as a fertilizer was determined to be 3 g per 1 kg of soil (10 t/ha).
On the basis of epidemiological studies and literature data analysis it is possible to state that excessive contamination of soil by exogenous chemicals administered purposefully (pesticides and mineral fertilizers) and as a result, technologic pollution (lead, mercury, arsenic, molybdenum, etc.) causes high content of those contacting with soil: ambient air, water of water sources, cultivated plants. Human intake of significant amounts of exogenous chemicals, contaminating soil, may lead to changes in health status of the population, appearance of acute and chronic poisoning by exogenous chemicals.
