Abstract:

A complete record of annual methyl chloroform production has been compiled by combining early estimates in the technical literature (1951–1976) with audited production data supplied by chemical manufacturers (1970–1996) and with production and consumption estimates provided by the countries party to the Montreal Protocol (1989 to the present). From this, a new and comprehensive estimate of annual emissions has been developed. However, when the atmospheric concentrations calculated from these annual emissions are compared with measured concentrations, there are significant discrepancies, particularly during recent years, that merit further examination.
