Additional information

  • The phototransformation half-life in air was found by Taylor et al. (1992) to be between 87.2 and 50.2 days in the temperature range from 295 to 339 K and with a OH-radical concentration of 5x10-5/cm3. This result was supported by AOPWIN (half-life: 46.78 days with 12h- day and 1.5E6 OH/cm3 at 25°C).
  • Hydrolysis testing (UNEP, 2000; Vogel et al., 1987, HYDROWIN) showed that the substance was stable at pH = 7 and at temperatures of 20 to 25°C.
  • The potential of 1,1,2-tricholoethane to undergo biodegradation and bioaccumulation is considered to be low.
  • Environmental modeling (Mckay model) show that, if 1,1,2-trichloroethane is released into air, it is unlikely to be distributed into any other compartments. If 1,1,2-trichloroethane is released into water or soil, it is likely to be transported to air for some part. (SIDS, 2000, EPI suite)
