Sorption-desorption, degradation and transport are the processes that affect presence of a pollutant in the soil. Chlorinated pesticides are not more used in the agriculture, except certain cases. But notwithstanding that the pesticides continue to presenting the soil due to their high persistence and low water solubility. Additionally, biomagnification as property of chlorinated pesticides makes them highly dangerous. So, soil pollution with the pesticides is still actual problem. Therefore retention processes (sorption-desorption) relatively chlorinated pesticides in the soil are worth of attention to evaluate potential of pesticides transport in adjacent media. "Aging" of DDE (2,2-bis(4-chlorophenyl)1,1-dichloroethylene) as factor affecting DDE mobility in the soil in the soil was the aim of the study. During the study acetone and water soil extracts were periodically analyzed relatively DDE presence. Negligible changes in water- extractable DDE, acetone-extractable DDE decrease, unextractable DDE increase and low DDE mineralization level depending on "aging" were detected as a result. That shows certain potential regarding ground water protection from contamination with the pesticides occurring in the soil.
