| 英文摘要 | To explore the residual characteristics of fluorine and perfluorinated compounds (pfcs) in tea, the total fluorine (tf), extractable organofluorine (eof) and pfcs in 19 chinese commercial teas of five categories were measured using cyclic neutron activation analysis combined with hplc-ms/ms. the results showed that fluorine mainly existed as inorganic fluorine in teas, and identified fluorine (epfcs quantified as f) only accounted for 0.023-0.41% of sigma of, indicating that most eof in tea were still unknown. 50-99% of sigma pfcs in tea were short-chain (c <= 6), while perfluorooctanoic acid was the typical pfcs residual species. less fermented teas contained significantly higher pfcs (mean, 20 ng/g) than more fermented teas (3.0 ng/g, p < 0.01), suggesting that microbe may degrade pfcs during fermentation. the highest tf content was discovered in hubei brick tea, which poses risk of fluorosis, whereas pfcs residues in teas caused no immediate harm.
