Contaminated revelation of PFCs in a water regime in Tokyo
PFCs have on superior characteristics of heat resistance and chemical resistance, and they are often used for industrial applications. Thereafter, they are mainly drained as factory effluent into the environment. Because PFCs drained into the environment have high water solubility, they exist in hydrosphere in the environment. We analyzed PFCs in Tokyo bay and theTama river in Tokyo using LC/MS/MS to investigate the actual situation of these environmental pollutants. The measured chemicals were 13: PFBS, PFHxS, PFHxA, PFHpS, PFHpA, PFOS, PFOA, PFNA, PFDS, PFDA, PFUdA, PFDoA, PFTrDA. In the depth of the Tokyo bay PFHpS, PFHxA, PFHxS, PFOA, PFOS, PFNA, and PFDA were detected. And in the Tama river PFOA, PFOS, and PFNA were detected. Comparison of concentrations of PFCs in the Tama River in December 2008 to those in July 2008 revealed decreased concentrations of PFOS. No significant differences were found in the concentrations of PFOA between the two months.
