Abstract
Vegetables and tree leaves are an important part of healthy diet due to their nutritional value, so contamination of vegetables and tree leaves may be dangerous for the population. Polycyclic aromatic hydrocarbons (PAHs) are compounds that are widely distributed in the environment and many of them exhibit carcinogenic effects. PAHs can enter the food chain in a variety of ways; hence the examination of PAHs in food is important. The current study examines the amounts of PAHs for ten of these compounds which are acenaphthene (Ace), acenaphthylene (Acy), fluorene (Flu), naphthalene (Np), anthracene (An), phenanthrene (Ph), benzo[α]anthracene (B[α]An), chrysene (Chry) , pyrene(Py), benzo[α]pyrene (B[α]Py) , In the following samples ( celery , watercress , cress , Eucalpt , mandarin , orange). The current study showed the presence of naphthalene in all samples, and the highest concentration was recorded in the Eucalyptuse leaves sample from the Doura region (19.433ppm) and the lowest concentration recorded in the Taji watercress sample (0.0785ppm). It was noted that the presence of pyrene by 66.66% and benzo-a-pyrene by 77.77%, while chrysene did not appear in any of the samples.
