Organochlorine pesticides in honeybee, pollen and honey in Bursa, Turkey

g-In this study, the presence of OCP residues in the honeybee, pollen and honey samples in urban and semi-urban areas were investigated. A total of 10 OCP concentrations (∑10OCP) in honeybee samples were 39.14 ± 11.06 ng g-1 for the urban area and 39.93 ± 7.09 ng g-1 for the semi-urban area, respectively. Similarly, ∑10OCP concentrations in pollen and honey samples were estimated to be 21.72 ± 4.43 ng g-1 and 41.83 ± 1.61 ng g-1 for the urban area, 19.77 ± 2.86 ng g-1 and 39.23 ± 3.90 ng g-1 for the semi-urban area, respectively. Also, it was concluded that the existence of OCP residues in both sampling areas was due to the recent use of pesticides. Finally, the cancer risk caused by the consumption of pollen and honey samples was evaluated, and it was found that there was no cancer risk in both sampling areas.
