Co-operative Studies on the Methodology for Japan-China Joint Research on Air Pollution

几个中国组织提出的主题，如日中联合研究，通过举行了几次会议进行了讨论。访问日本的中国研究人员也参加了几次会议。在大量参考资料和数据的基础上，分析了中国空气污染的现状，并调查了中国空气污染的显著特征。在此基础上，研究了中国大气反应的研究方法、大气污染物的测量方法以及大气污染对人体、植被、金属等的影响。提出了在现场测量一次大气污染物向二次大气污染物转化速率的新方法。澄清了几个与酸雨形成或氧化剂形成有关的新反应和催化反应。为了更清楚地了解中国大气污染状况，提出了SO_2、NO_x、O_3、NH_3、H_2O_2、硫酸盐、硝酸盐、芳香烃、醛类和醇类的几种评价方法。讨论了简易方便的空气污染监测仪的应用，并介绍了该监测仪在中国空气污染野外调查中的应用。讨论了中国酸雨中硫化物含量的分析方法。强调了云水分析对酸雨形成的重要性。新的资料是关于亚洲沙尘（科沙）的。提出了研究大气污染对峨眉山植物和树木、对桂林利尼斯顿洞、对全国人体影响的具体方案。文中还讨论了抑制污染源大气污染物排放的方法。

The Subjects proposed from several chinese organizations, as Japan-China joint researches, were discussed, by holding several Meetings. Chinese researchers, who visited Japan, jointed some times in this meeting.The Present situation of air pollution in China was analyzed, based on many references and data, and the distinctive features of air Pollution in this country were investigated. Based on these results, the methodology to study atmospheric reactions, measurements of air pollutants, and effects of air pollution on human body, vegetations, metals and so on in China were studied.New method to measure the conversion rate of primary air pollutants to secondary air pollutants on the site were developed. Several new reactions and catalytic reactions which have relations to acid rain formation or oxidant formation were clarified.Several review methods to measure SO_2,NO_x,O_3,NH_3,H_2O_2,sulfate, nitrate, aromatic iydroc bons, aldehydes, and alcohols, were developed in order to know the air pollution in China more clearly. The utility of simple and handy air pollution monitors was discussed and the application of these monitors to field survey of air pollution in China was recommended.The methodology to analyze the ioriie content of acid rain in China was discussed . The importance of analysis of cloud water was emphasized, relating to the acid rain formation. The new information was obtained on Asian dust (Kosa).The concrete plan to study,the effect of air pollution on plants and trees in Emei mountain, on linieston cave in Guilin, on human bodies in whole China were proposed. The methodology to suppress emission of air pollutants in sources was also discussed.
