The studies were carried out on 3 apiaries in the Olsztyn district. One apiary (K) was located in the suburb of the town, the second (U) in the garden of a farmer and the third (Ł) in the former state farm. The samples bees, honey and propolis, were collected in mid-July from 5 families of each apiary. It was found that the content of chlorinated carbohydrates in the organism of bees and bee-products was dependent on the apiary location. The highest content of HCH was found in propolis (0.0401-0.0502 mg/kg) and in the bees coming from the Ł and K apiaries (0.0193-0.0662 mg/kg). The level of DDT in the bees, honey and propolis was also dependent on the apiary location. The highest amount of DDT compound was found in the bees from the Ł and K apiaries (0.0315 and 0.0312 mg/kg, respectively) and the lowest in honey (0.0043-0.0075 mg/kg).
