Abstract

Abstract:

A large quantity of aviation hydraulic fluid containing PFCs is used in airplanes in one of the international airports in Shanghai. It is also used in the airport interior and the nearby fire station. In fire drills or emergencies, Aqueous film-forming foams (AFFFs) is used. PFCs is an important component of AFFFs. Its excessive use may cause fluoride pollution in the neighboring surface water. In this study, 10 surface water samples were collected in the airport to detect 17 types of perfluormated compounds (PFCs). The results show that perfluorooctanoic acid (PFOA) is the predominant PFC, in the range from 37.55 ng/L to 189.05 ng/L, with a mean value 94.05 ng/L. Concentrations of perfluoro pentanoic acid (PFPeA) and perfluorobutane sulfonate (PFBS) in the surface water samples are in the range from 15.15 ng/L to 42.33 ng/L with a mean value 27.82 ng/L, and from 5.35 ng/L to 57.27ng/L with a mean value 24.12 ng/L,respectively. The detection rates were all 100%. The risk quotient was used for PFC in the surface water samples, showing that PFC in water had no ecological risk temporarily.

Key words: perfluorinated compound (PFC), airport, surfacewater, concentration distribution
