Abstract EN
A Chinese medicinal fern Blechnum orientale (Linn) was separately collected from polluted and unpolluted sites to determine whether it could accumulate hazardous pollutants or not.
Metal concentrations (Cu, Zn, Mn, Pb, Cd, Cr, As, and Hg) both in the fronds and roots and polycyclic aromatic hydrocarbons (PAHs) in the fronds of this fern were quantified.
At both sites, roots of B.
orientale had significantly higher heavy metals than the fronds.
Concentrations of Pb, As, Hg, Cd, and Cu in the fronds at the polluted site were more than 2, 6, 7, 14, 5, and 13 times of those at the unpolluted site.
Translocation factor and bioaccumulation factor implied that B.
orientale did not have a good ability to transport heavy metals from the roots to the fronds.
Total PAHs in the fronds at the polluted site were significantly higher than those at the unpolluted site, indicating the physiological PAHs absorption by B.
orientale growing at polluted sites.
Uptake of pollutants via stomata might be the main reason causing the significant accumulation of hazardous pollutants in the fronds of B.
orientale.
Large-scale systematical survey and intensive monitoring on pollutants in this medicinal fern should be necessarily strengthened.
