PAHs IN AEROSOLS AT DINGHUSHAN NATURAL PROTECTION ZONE
-
摘要: 多环芳烃(PAHs)是环境中分布广泛、危害人类健康的有机化合物.通过对鼎湖山自然保护区自然地理和大气气溶胶中苯并(a)芘分析认为, 春季样品中大气气溶胶中PAHs主要来源于高等植物排放, 夏季来源于珠江三角洲经济区化石燃烧排放.Abstract: The PAHs, widely distributed in our environment, and harmful to our health, is a kind of organic compounds. The analysis of the natural geography in the Dinghushan natural protection zone and that of the benzopyrene in aerosols conclude that the content of PAHs in aerosols in the spring samples comes mainly from the emission from the plants. However that in the summer samples comes mainly from the discharge of the fossil burning in the Pearl River Delta Economic Zone.
