中文摘要：为了研究海洋背景区域大气中多氯联苯(PCBs)的污染状况,于冬、春和夏季在福建省沿海岛屿东山岛连续采集大气颗粒物样品.结果显示,东山岛大气颗粒物中PCBs浓度范围为0.11—16.95 pg·m^(-3),平均值5.53±4.31 pg·m^(-3).通过对比其他区域发现,东山岛大气颗粒物中PCBs处于较低水平,其含量与海洋背景区域相当.PCBs浓度季节变化明显,表现为冬春季高而夏季低.冬季,PCBs以高氯取代化合物为主,而春、夏季以低氯取代化合物为主.气团来源的季节性变化、气象条件参数(如降雨量、温度、大气压、风速、相对湿度、水气压)是影响PCBs浓度变化的主要因素.东山岛大气颗粒物中PCBs的干沉降通量为1.34 ng·m^(-2)·d^(-1),冬春季沉降通量明显高于夏季,按照东山岛海域覆盖面积(36200 km^2)估算,每年PCBs以干沉降入海通量约为12.84 kg.

外文摘要：To investigate the pollution status of polychlorinated biphenyls（PCBs）in the marine background area,atmospheric particulate matter samples were collected from June to August 2006 and January to August 2007 in Dongshan Island,Fujian province.The results showed that the concentrations of∑28PCBs in the atmospheric particulates of Dongshan Island ranged from 0.11—16.95 pg·m^（-3）,with an average of 5.53±4.31 pg·m^（-3）.Compared with other areas,the average concentration of PCBs in Dongshan Island was lower.Higher concentrations of PCBs were observed in the winter and spring whereas lower in the summer.PCBs in atmospheric particles were dominated by higher chlorinated PCBs in winter,while lower chlorinated PCBs were the main component in the spring and summer.The major factors that influence PCBs concentrations were the air mass origins and meteorological parameters（such as rainfall,temperature,atmospheric pressure,wind speed,relative humidity and water vapor pressure）.Dry deposition fluxes of PCBs in Dongshan Island were1.34 ng·m^（-2）·d^（-1）,and the fluxes in the winter and spring were significantly higher than in the summer.According to the coverage area of Dongshan Island（36200 km^2）,PCBs in atmospheric particles deposition fluxes into the surface waters were 12.84 kg per year.
