《环境化学》中“光化学烟雾”与“硫酸烟雾”知识点解析

Analysis of Photochemical Smog and Sulfuric Acid Smog in Environmental Chemistry

"光化学烟雾"和"硫酸烟雾"是大气污染化学的重要内容,涉及重要污染物氮氧化物和硫氧化物的迁移转化,形成过程复杂多样,在教学目标中属于重点和难点学习。为帮助学生更好的理解和掌握"光化学烟雾"和"硫酸烟雾",本文分别从概念、烟雾成因、形成机制及其烟雾的危害和措施等四个方面阐述和讨论,最后通过比较两者的差异,帮助学生更好地理解学习。

"Photochemical smog"and"sulfuric acid smog"are two major chemical pollution phenomena,involving the migration and transformation of important pollutants nitrogen oxide and sulfur oxide.The formation processes are complex and diverse,which belong to the key and difficult points of learning in the teaching objectives.In order to help students understand and master"photochemical smog"and"sulfuric acid smog",the concept,cause of smog,formation mechanism and the hazards and measures of smog were expounded and discussed,comparing the two differences can help students better understand learning.
