Kinetics and mechanism of gas-phase reaction of CF3CF2CF2CF2CF2CF2CF2CF2H with OH radicals in an environmental reaction chamber at 253-328Â K

► Kinetics and mechanism for CF3(CF2)7H reaction with OH radicals were determined in an 11.5-dm3 environmental reaction chamber by means of Fourier transform infrared spectroscopy. ► The atmospheric lifetime for CF3(CF2)7H were estimated to be 24 years. ► The molar yield of PFOA from the oxidation of CF3(CF2)7H was estimated to be 0.07-0.12.
