Abstract
Salad, soybeans, rye and tobacco plants, grown on field in the open air or in greenhouses contain benzo (e) pyrene, benzo (a) pyrene, perylene, anthanthrene, benzo (ghi) perylene, dibenzo (a,h) anthracene, and coronene through air pollution. Plants of the same seeds, grown in a special room with air supply by filter-combination (cellulose filter + filtering charcoal + special filters) and with air lock for personnel (changed clothes) show non of the polycyclic hydrocarbons. Under these conditions, it is not possible to find any hints at biosynthesis of the above mentioned polycyclic hydrocarbons.
