摘要

After deposition to foliage, polycyclic aromatic hydrocarbons(PAHs)may remain on the leaf surface, accumulate in the cuticular wax, or diffuse into the remaining interior of the plant. In a field study, the location of deposited PAHs in the leaves of two Plantago species was determined. To this aim, leaves of Plantago major and Plantago media were divided into three fractions. First, the leaves were washed(wash-off fraction), then cuticular wax was extracted(wax fraction). Finally, the remaining leaf material was extracted(interior fraction). The presence of PAHs could be demonstrated in all three fractions.
