According to the data provided by Food and Agriculture Organization of UN, the amount of obsolete pesticides (OPs) located in Kazakhstan nowadays is around 10000 tons. According to the recent scientific data, relatively high concentrations of OPs are detected in environmental samples possessing high risks of their accumulation in vegetables and animals used as food by local population. The goal of the present research was to determine concentrations of organochlorine pesticides in local and imported food samples taken from markets in Kazakhstan.Analyses were conducted using GC-MS and optimized sample preparation that included extraction, cleanup by passing the extract through multi-layer adsorbent followed by evaporative concentration. The following samples were analyzed: meat, fish, dairy products, vegetables and fruits. In food samples, only metabolites of DDT were detected. Highest concentrations of 4,4'-DDE were found in samples of vegetables (131 ng/kg) and fish (118 ng/kg).
