Modern inhalation anesthetics undergo little metabolization during clinical application. From urban areas to the pristine Antarctic environment, we detect a rapid accumulation and ubiquitous presence of several anesthetics in the global atmosphere.
Trifluoromethane (CHF3, HFC-23), with a 100-year global warming potential (GWP) of 12400, is regulated under the Kyoto Protocol.
This electronics industry celaning solvent is considered only a minor contributor to global radiative forcing; however, our calculated emissions differ significantly from the available reported figures and projected estimates.
Long-term AGAGE measurements with global coverage are presented for four potent greenhouse gases: a fire-suppressant, a refrigerant, and two commercially-used foam blowing substances.
After almost a decade with little change in global atmospheric methane mole fraction, measurements from the AGAGE and CSIRO networks show renewed growth starting near the beginning of 2007.
Background atmospheric abundances and trends of nitrogen trifluoride (NF3), a potent anthropogenic greenhouse gas, have been measured for the first time.
