【摘要】 1989年2月在台山铜鼓湾海边对水溶性气溶胶的离子成分Cl^-、NO₃^-、SO₄⁼、Na⁺、K⁺、Mg⁺⁺进行了分析,发现其中主要离子成分是Cl^-与Na⁺,它们都来自海盐气溶胶,Mg⁺⁺亦来自海盐;而K⁺主要是陆源性的;SO_<sup>=的来源以海盐为主,但也反映出受东亚大陆较严重大面积硫污染影响的特征;而NO₃^-有较高的富集现象,且100％为非海盐成分,应是局地人类活动,如农耕与炊事影响所致。更多还原

【Abstract】 Ionic compositions of water soluble aerosols observed at the seashore of the Tong-gu Bay in Taishan,Guangdong Province during Feb. 1989,namely,C1-,NO₃^-,SO₄⁼,Na+,K+ and MgH ,are analyzed. It is found that the dominant ions are Cl- and Na+ ,which are of marine salt aerosol. The same origin is with MgH,too. K+ mainly comes from the continent. And SO4= from sea salt mostly. It does reveal,however,the large scale high pollution of sulfar in the continent of East A-sia. The study points out that high concentration of NO₃^- is of 100% non-sea-salt origin. It is obvious that this is related with local farming and household cooking.更多还原
