| 释义 | sulphur dioxide noun[ U ] mainly UK(US usuallysulfur dioxide)uk /ˌsʌl.fə daɪˈɒk.saɪd/ us /ˌsʌl.fɚ daɪˈɑːk.saɪd/ a gas that has a strong, unpleasant smell and dissolves in water. It is used in various industrial processes, and can cause air pollution.二氧化硫 Chemicals, chemical compounds & gases acetic acid acetone acrolein acrylamide activated charcoal adenine agglomerate ethyl alcohol glyphosate H2O HCFC HFC hyaluronic acid hydrochloric acid laughing gas limescale meths oxyacetylene prussic acid tartaric acid Examples of sulphur dioxidesulphur dioxide An experiment has also been made which includes emissions of sulphurdioxide and thus the formation of aerosols. It is possible that by removing magazines from the incinerator waste, sulphurdioxide emissions will decrease. The nature of this greenhouse effect is disputed - the relative roles of sulphurdioxide and carbon dioxide in the greenhouse are strongly debated. Specific examples would be reducing emissions of sulphurdioxide or reducing concentrations of lead in air or water. The impact of trade appears to vary by pollutant, with only sulphurdioxide showing evidence of both factor endowment and pollution haven effects. The declining trend in sulphurdioxide emissions: implications for allowance prices. He finds both to be positive determinants of sulphurdioxide concentrations. As with sulphurdioxide, the results for nitrogen oxides provide evidence of a robust relationship between per capita income and emissions. Numerous covariates have been introduced in the past to explain sulphurdioxide concentrations in reduced-form specifications. For sulphurdioxide and nitrogen oxides we have five-yearly observations for 26 developed and developing countries, covering the period 1975 - 1990. Only for sulphurdioxide does the analysis suggest that trade patterns driven by environmental regulations and/or factor endowments are determining per capita emissions. Estimated turning points are also broadly similar across specifications and are slightly higher than those estimated for sulphurdioxide. The highest sulphurdioxide emissions occurred in burns that included magazine waste. The positive estimate throughout provides strong evidence that more human/physical-capital-intensive countries have higher sulphurdioxide concentrations, even after we control for trade and income effects. The trade intensity variable is negative for sulphurdioxide, nitrogen oxides, and biological oxygen demand (although it is not significant for nitrogen oxides) whilst it is positive for carbon dioxide.
