The distribution of polycylic aromatic hydrorarbons(PAHs) has been determined by authors. The determining methodand results are reported in this article. The measures of reducing the pollution by polycyclic aromatic hydrocarbons are also proposcd.Samples were collected at five xample points in Nanchong city during winter and summer. The method and steps for sample treatmentare: ultrasonic extracting ,suction fitlrating ,vaccum concentrating,purifying with silicagel column ,secondary concantrating and then dis-solving the sample in definite amount of methanol. The PAHs were separated and determined with high performance. The over-year av-erage concentration of benzo(a)pyrene in air was 31.5ng/m ̄3 in Nanchong, it was a little less than that of Chegdu in 1988.The mainsources of PAHs are coal burning and then vehicle exhausting. Changing fuel structure, supplying heat centrically,and strengtheningcity’s traffic control are the main measures of reducing PAH pollution.

用超声波萃取、抽滤、减压蒸发浓缩,硅胶柱净化,再浓缩至干,定客溶解的方法处理了南充市5个监测点冬、夏季米集的大气颗粒物样品,然后,用高效液相色谱法分析其中9种多环芳烃含量。大气中苯并[a]芘的年平均含量为31.5ng/m ̄3,略低于成都市1988年测定的年平均值。南充市大气中多环芳烃的主要来源大居民生活用煤,其次是汽车尾气。改变燃料结构,集中供热,加强城市交通管理,是减少多环芳烃污染的途径。

An investigation on levels of polycyclic aromatic hydrocarbons (PAHs) in surface water of Xiamen Harbor has been conducted on spring, summer and autumn cruises in 2001 and at six locations. The results showed that the concentration and composition of PAHs in the surface water were variable. The pollution levels of PAHs in April and October were higher than that in July concentrations of total. PAHs in the surface water were mainly dominated by naphthalene (2 rings) in April, acenaphthene (3 rings) in...

An investigation on levels of polycyclic aromatic hydrocarbons (PAHs) in surface water of Xiamen Harbor has been conducted on spring, summer and autumn cruises in 2001 and at six locations. The results showed that the concentration and composition of PAHs in the surface water were variable. The pollution levels of PAHs in April and October were higher than that in July concentrations of total. PAHs in the surface water were mainly dominated by naphthalene (2 rings) in April, acenaphthene (3 rings) in July and chrysene (4 rings) in the October. The concentrations of anthracene and benzo(a)pyrene in surface water was higher than the toxicity guidelines. The origin of PAH pollution in surface water of Xiamen Harbor was mostly petrogenic.

通过 3个航次对厦门西港表层海水中 16种优先监控的PAHs的污染状况进行不同季节的连续调查 .结果表明 :表层海水中PAHs的含量与组成具有明显的时间差异 .在 4月和 10月的PAHs含量较 7月高 ;PAHs的组成在 4月以 2环的萘为优势组分 ,在 7月以 3环的苊烯为优势组分 ,10月以 4环的为优势组分 .分析 3个航次的调查结果发现 :厦门西港表层海水中的PAHs主要来源于石油类物质的输入 .厦门西港表层海水中各种PAHs的含量与国际生物学组织或国家制定的评价水生生物暴露于水体的安全食用标准相比虽未超标 ,但个别组分如蒽、苯并 [a]芘的含量已达到生态毒理评价标准 .
