备注

为探究深圳市典型行业全氟化合物(perfluoronic compounds, PFCs)污染指纹,应用固相萃取分离富集与高效液相色谱-质谱联用相结合的方法,于2013年4月至6月对深圳市五金电镀、电子、塑胶和涂料4类行业28份靠近一次排放源表层土中14种PFCs含量进行分析.结果显示,全氟辛烷磺酸(perfluorooctane sulfonate, PFOS)是五金电镀行业PFCs排放的特征污染指纹, 电子行业为PFOS与全氟辛酸(perfluorooctane acid,PFOA),而塑胶和涂料行业

In order to explore the perfluorinated compounds(PFCs)pollution fingerprints of typical industries in Shenzhen, high performance liquid chromatography-tandem mass spectrometry was combined with solid phase extraction enrichment to analyze the contents of 14 PFCs species in 28 topsoil samples collected from primary emission sources of metal electroplating, electronics, plastics and coatings in Shenzhen. The results show that perfluorooctane sulfonate(PFOS)is the characteristic PFCs pollution fingerprints of metal electroplating, and PFOS and perfluorooctane acid(PFOA)are those of electronics. PFOS, PFOA as well as long-chain PFCs are those of plastics and coatings. Total PFCs in topsoil rank in the order of metal electroplating >> electronics > plastics > coatings >> the urban background. The PFCs distribution order is medium- >> long-> short-chain PFCs for electroplating and electronics, and medium-> long- >> short-chain PFCs for plastics and coatings. The results can provide scientific bases for environmental monitoring and pollution control.
