目前,酸雨(Acid Rain)已成为国际舆论所公认的重大的环境问题之一。随着燃煤量的增加,SO_2的排放量也将随之增加,降雨酸性势必有所增加。酸雨对蔬菜的危害虽受到国内外科学工作者的普遍关注,但有关自然酸性降雨对蔬菜影响研究尚未见报道,目前酸雨对作物危害的研究仍局限于室内及田间摸拟试验。国外除Lee、Hindawi,Evans等人进行这方面的试验外,国内很少有报道。另据市有关单位监测,本市近郊降雨酸度有增强趋势。因而开展“酸雨对蔬菜影响”的研究显得格外重要。
At present, Acid Rain has become one of the major environmental issues recognized by the international public opinion. With the increase of coal consumption, SO 2 emissions will also increase, rainfall acidity is bound to increase. Although the harm of acid rain to vegetables has drawn widespread attention of scientists both at home and abroad, the research on the impact of natural acid rain on vegetables has not been reported yet. At present, the research on crop damage caused by acid rain is still limited to indoor and field experiments. Abroad, Lee, Hindawi, Evans, who conducted this test, the domestic rarely reported. According to other municipal monitoring units, the suburbs of the city rainfall acidity has increased. Therefore, carrying out “acid rain on vegetables,” the study is particularly important.
