POPs chemicals threat human health and the environment all over the world. The intense use of organochlorinated pesticides (OCPs) in the past, which reached a peak in the 1970s, caused pesticides accumulation in and contamination of soil and crops. Presently it is well-known that some OCPs can persist in the soil for 10–20 years and more. This explains why DDT and its metabolites are still detectable in the Moldovan environment (soils, aquatic sediments), despite the fact that it was banned in 1970 and have not been used in significant amounts since then. Another problem not less important is that in the Republic of Moldova there are more than 6,400 tons (according to 2005 data) of obsolete pesticides. This amount of pesticides (DDT, HCH, Heptachlor, Polychlorcamphen and other obsolete chlororganic pesticides) are stored in inappropriate conditions. These stores and surrounding areas are an “ecological bomb” for environment.
