CFC和卤代烷禁令CFC and halons prohibition An interdiction on the manufacture or use of products that discharge chlorofluorocarbons and bromine-containing compounds into the atmosphere, thereby contributing to the depletion of the ozone layer
替代卤代化合物substitution of halogenated compounds Halogenated compounds, because of their toxical and persistent character, should be substituted by environmental friendly compounds, like water-based fat solvents in metal processing industry or water-based coating agents (卤代化合物由于其产生毒性和持久性的性质,应该由环保物质代替,如在金属加工行业或水性涂料剂中的水性脂肪溶剂。)
部分卤代partially halogenated chlorofluorohydrocarbon Hydrocarbons whose hydrogen atoms have been partially substituted with chlorine and fluorine. They are used in refrigeration, air conditioning, packaging, insulation, or as solvents and aerosol propellants. Because they are not destroyed in the lower atmosphere they drift into the upper atmosphere where their chlorine components destroy ozone (碳氢化合物的氢原子已经部分取代氯氟。它们被用于制冷、空调、包装、保温、或溶剂和气溶胶推进剂。因为当它们漂流到大气时,不会对上部大气圈的臭氧造成破坏。)
