Shape 5 Levels off CFC-eleven, CFC-12 and you can CFC-113 when you look at the closed ampoules out-of Withlacoochee River-water out-of southern area-eastern Georgia appearing destruction of CFC-11 and CFC-113 and you can visible balances away from CFC-12 (out of Plummer ainsi que al., 1998b).
CFCs were not degraded inside the ampoules of river water held lower than white during the room temperature. Development of alga is observed in such ampoules hence most likely suffered aerobic criteria (Plummer et al., 1998b).
Create et al. (1995) presented almost done degradation off CFC-11 and balances out-of CFC-12 for the an excellent sulphate-reducing mud aquifer close Sturgeon Drops, Ontario, Canada. Indeed there new groundwater decades based on CFC-twelve consented really into the noticed depth of your middle-sixties step three H bomb peak. Less than marine, sulphate-cutting requirements when you look at the a beneficial Norwegian fjord, Shapiro mais aussi al. (1997) receive fast destruction of CFC-11, and you can, in uncertainties of one’s measurements, CFC-12 destruction could not were more than step one/600 that CFC-eleven. Brand new 1 / 2 of-lives to have CFC-11 degradation from inside the sulphate-cutting, natural steeped seawater is actually 0.step one ± 0.02 decades and you can much more smaller compared to you to definitely found because of the Prepare ainsi que al. (1995) regarding 0.nine to just one.seven years. Weiterlesen „CFC-11 and you may CFC-113 were completely degraded contained in this eight hundred weeks and you can CFC-a dozen exhibited almost no destruction more than almost 1000 months“
