In 2005 for the first time in Kazakhstan a limited analysis of the samples for dioxins and furans content in the environment was carried out. A high level of air pollution and dust in the workshops of selected nonferrous enterprises was revealed. There was no active soil pollution through the atmospheric transfer detected. However, there were circumstances that raised doubts to the lack of soil pollution. They are based on the results of the landscaping and geochemical as well as ecological and epidemiological studies of Balkhash city where a Mining and metallurgical integrated works is situated. Strategic objectives of the NIP in the sphere of unintentionally produced products are being considered.

The aim of this study was to determine the PBDE contents in selected food products available on the Polish market: butter, eggs, chocolate, pork fat, beef fat, and three kinds of fish: carp, salmon and cod. Therefore, a two-stage (for fish) and three-stage (for all the other food products) methods of sample cleanup was developed with the use of the GC-MS technique, using semipermeable membranes (SPM) in one of the stages. In all of the samples six dominating PBDE congeners: BDE-28, BDE-47, BDE-99, BDE-100, BDE-153, and BDE-154 were determinated. PBDE contents in the Polish butter ranged from 55 to 174 pg/g of fat. The results for the fish samples (salmon and cod) were shown to be highly variable. The analysed salmon samples contained for example 377–5,340 pg/g of the wet muscle tissue (1,850–26,700 pg/g of fat, respectively).
