چکیده
Abstract. Global emissions of the ozone-depleting gas HCFC-141b (1,1-dichloro-1-fluoroethane, CH3CCl2F) derived from measurements atmospheric mole fractions increased between 2017 and 2021 despite a fall in reported production consumption for dispersive uses. is controlled substance under Montreal Protocol, its phase-out currently underway, after peak developing (Article 5) countries 2013. If are correct, our study suggests that 2017–2021 rise due to an increase bank when appliances containing reach end their life, or not Regional have been estimated 2017–2020 all regions where sufficient sensitivity emissions. This includes northwestern Europe, east Asia, United States Australia, decreased by total 2.3 ± 4.6 Gg yr?1, compared mean global 3.0 1.2 yr?1 over same period. Collectively these only account around 30 % 2020. We able pinpoint source specific activities responsible recent emission rise.

Using hydrofluoroether solvents to replace HCFC-141b, Part II.
The use of hydrochlorofluocarbon (HFC) solvents is banned from the end of 2001. Part of this article assessed the merits of using hydrofluoroethers as replacement solvents. Alternatives to HFCs are more expensive. Part II looks at how to reduce the cost of conversion.
متن کاملHfc - 23 Emissions from Hcfc - 22 Production
The compound HFC-23 (Trifluoromethane or CHF3), a potent greenhouse gas with a 100-year global warming potential of 11,700, is generated as a by-product during the manufacture of HCFC-22 (chlorodifluoromethane or CHClF2). This paper outlines options and issues for good practice guidance in the national inventory management of HFC-23 emissions from HCFC-22 production. The issues presented are or...
متن کاملMetabolism of 1,1-dichloro-1-fluoroethane (HCFC-141b) in human volunteers.
Human subjects were exposed by inhalation to 250, 500, and 1000 ppm 1,1-dichloro-1-fluoroethane (HCFC-141b) for 4 hr, and urine samples were collected from 0-4, 4-12, and 12-24 hr for metabolite analysis. 19F nuclear magnetic resonance spectroscopic analysis of urine samples from exposed subjects showed that 2,2-dichloro-2-fluoroethyl glucuronide and dichlorofluoroacetic acid were the major and...
متن کاملMeasurements of the infrared absorption cross-sections of HCFC-141b (CH3CFCl2)
Detection of atmospheric trace gases by optical remote sensing techniques relies on the availability of molecular absorption spectra over a range of relevant temperatures. Absorption cross-sections of a pure vapour of the hydrochlorofluorocarbon HCFC-141b are reported at a resolution of 0.02 cm 1 for a range of temperatures between 223 and 283 K and a spectral range of 570–3100 cm . The integra...
متن کاملGlobal emissions of refrigerants HCFC-22 and HFC-134a: unforeseen seasonal contributions.
HCFC-22 (CHClF2) and HFC-134a (CH2FCF3) are two major gases currently used worldwide in domestic and commercial refrigeration and air conditioning. HCFC-22 contributes to stratospheric ozone depletion, and both species are potent greenhouse gases. In this work, we study in situ observations of HCFC-22 and HFC-134a taken from research aircraft over the Pacific Ocean in a 3-y span [HIaper-Pole-to...
