[Distribution characteristics of the typical persistent organic pollutants (POPs) in Suaeda heteroptera].

The Suaeda heteroptera are widely distributed in intertidal zone, in order to investigate its function in preventing the transfer of the contaminants from land to sea, the levels and the distribution characteristics of organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs), decabromodiphenyl ether (BDE209), and polychlorinated biphenyls (PCBs) in Suaeda heteroptera and their associated soils were studied with GC-MS. The results indicated that the levels of these pollutants in Suaeda heteroptera were in the following order: sigma PAHs > OCPs > BDE209 > sigma PCBs (96-1 506 ng/g, 14-577 ng/g, 1.8-33 ng/g, and 399-2 161 pg/g, respectively).
