ABSTRACT
The conducted research has demonstrated that the general rapeseed contamination with benzo(a)pyrene (B(a)P), as the main representative of the PAH family, is at the level of permitted world standards. However, individual cases of dried samples where the B(a)P content was high enough to reach 8.30 ľg kg-1 of seeds, show that the problem of seed pollution by the polynuclear aromatic hydrocarbons is still unsolved and the raw material for further processing should be carefully monitored. Monitoring the PAH risks seems most appropriate given the presence of B(a)P in the samples without any post-harvest treatment. It demonstrates how common the occurrence of the substance is in the human environment. Significant variance between the samples taken directly after the harvest and these after the drying, shows how important the process of drying is on the content of B(a)P. The increased level of the substance in the seeds from the year of adverse weather conditions demonstrates that the drying time and data missing to a great extent affect the quality of the seeds.
