possible to estimate preindustrial CC14 levels accurately from measurements in slowly renewed deep waters (1). In contrast, loss of CH3CC13 would be considerable even in cold waters over a period of only 40 years (that is, since CH3CC13 was introduced into the environment), and it has an input function that is not dramatically different in nature from those of F-li and F-12 (1). We thus reitera...

The domestic refrigerator market in Europe is undergoing rapid change brought about by: the phase out of CFCs, pending legislation for minimum energy efficiency standards, and the introduction of a compulsory point of sale energy label. All of these changes have occurred in a different manner in Europe than elsewhere. In particular, the design of the European energy label utilises a psychologic...

The attenuation of methane and four chlorofluorocarbons was investigated in a dynamic methane and oxygen counter-gradient system simulating a landfill soil cover. Soil was sampled at Skellingsted Landfill, Denmark. The soil columns showed a high capacity of methane oxidation with oxidation rates of 210 g m(-2) d(-1) corresponding to a removal efficiency of 81%. CFC-11 and to a lesser extent als...

Two mesoporous fluorinated metal-organic frameworks (MOFs) were synthesized from extensively fluorinated tritopic carboxylate- and tetrazolate-based ligands. The tetrazolate-based framework MOFF-5 has an accessible surface area of 2445 m(2) g(-1), the highest among fluorinated MOFs. Crystals of MOFF-5 adsorb hydrocarbons, fluorocarbons, and chlorofluorocarbons (CFCs)-the latter two being ozone-...

Dissociation induced by cosmic rays of chlorofluorocarbons (CFC) and HCl on the surfaces of polar stratospheric clouds (PSC) has been suggested as playing a significant role in causing the ozone hole. However, observed stratospheric CFC distributions are inconsistent with a destruction of CFC on PSC surfaces and no significant correlation exists between ozone levels and cosmic-ray activity insi...

The presence of chlorofluorocarbons (CFCs) in Earth's atmosphere is a direct result technology. Ozone-depleting CFCs have been banned by most countries, but some persistent elevated concentrations due to their long stratospheric lifetimes. are effective greenhouse gases and could serve as remotely detectable spectral signature Here we use three-dimensional climate model synthetic spectrum gener...
