متن کاملDegradation rates of CFC-11, CFC-12 and CFC-113 in anoxic shallow aquifers of Araihazar, Bangladesh.
Chlorofluorocarbons CFC-11 (CCl(3)F), CFC-12 (CCl(2)F(2)), and CFC-113 (CCl(2)F-CClF(2)) are used in hydrology as transient tracers under the assumption of conservative behavior in the unsaturated and saturated soil zones. However, laboratory and field studies have shown that these compounds are not stable under anaerobic conditions. To determine the degradation rates of CFCs in a tropical envi...
متن کاملStratospheric Loss and Atmospheric Lifetimes of CFC-11 and CFC-12 Derived From Satellite Observations
The lifetimes of CFC-11 and CFC-12 have been evaluated using global observations of their stratospheric distributions from satellite-based instruments over the time period from 1992 to 2010. The chlorofluorocarbon (CFC) datasets are from the Cryogen Limb Array Etalon Spectrometer (CLAES), the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA-1 and CRISTA2), the Michelso...
متن کاملValidation of Mipas-envisat Ch4, N2o, Cfc-11 and Cfc-12 by Airborne in Situ Observations
Airborne in situ measurements of the trace gases CH4, N2O, CFC-11 and CFC-12 with the High Altitude Gas AnalyzeR (HAGAR) on board the M55 Geophysica aircraft and the balloon-borne cryosampler BONBON of the University of Frankfurt are compared to vertical profiles from MIPAS-ENVISAT. We validate ESA level-2 standard products (v. 4.61) and non-operational trace gas profiles of CH4, N2O, CFC-11 an...
متن کاملRelease of CFC-11 from disposal of polyurethane foam waste.
The halocarbon CFC-11 has extensively been used as a blowing agent for polyurethane (PUR) insulation foams in home appliances and for residential and industrial construction. Release of CFCs is an important factor in the depletion of the ozone layer. For CFC-11 the future atmospheric concentrations will mainly depend on the continued release from PUR foams. Little is known about rates and time ...
