| Abstract | In order to assess the feasibility of typical plants as bioindicators for perfluorinated chemicals (PFCs), the residues of 13 PFCs in fresh leaves of moss, camphor tree, masson pine, gladiolus, lichen, alfalfa, silky oak and rhododendron were measured by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Moss, which accumulates PFCs most effectively among the eight, was selected as the environmental bioindicator for PFCs assessment. The total fluorine, extractable organic fluorine and PFCs in moss from 12 locations of six Shenzhen districts, including Bao'an, Nanshan, Futian, Yantian, Luohu and Longgang, were measured by cyclic neutron activation analysis combined with HPLC-MS/MS. Results showed that EOF accounted for 13.4%-16.5% of TF. They indicated that inorganic fluorine was the main form. Only 0.08%-0.15% of EOF was the identified fluorine while more than 99.8% of EOF required further identification. The sum of perfluorooctane sulfonate, perfluorooctanoic acid and perfluorohexanoic acid accounted for 88%-99% of total PFCs, making them the main PFCs species in moss. Total PFCs residues in moss from Bao'an district were significantly higher than those from other districts (P<0.01), which was likely due to the presence of PFCs-related industries, geographical location and climate. The results suggest that moss is a feasible bioindicator for PFCs and its exposure risk in the environment. |
