摘要：以养殖场培育的花尾胡椒鲷受精卵为实验材料测试了厦门西海域5 个站位的表层水水样对花尾胡椒鲷受精卵的胚胎发育毒性,并运用GC2MS 手段分析了水样中的美国EPA 优控的16 种PAHs 组分的含量。结果表明:3 号站位(厦门市工业和生活污水主要排放口的外侧) 和4 号站位(厦门西港的港区) 的水样对鱼卵的胚胎发育的毒性最强;8 号站位(位于主航道并濒临嵩屿电厂) ...的水样对鱼卵胚胎发育的毒性次之,1 号站位(湾口) 和5 号站位(内港) 的水样对鱼卵的胚胎发育的毒性较小。水样中的PAHs 含量分析结果表明,仅用水样中的PAHs 含量不能全面地反映水样对鱼卵胚胎发育的毒性。最后,对本实验方法应用于海洋环境生物监测的有效性进行了探讨。Abstract:Cultured zygotes of Plectorhi nchus ci nct us were done to make test the toxicity of surface water samples in Western Xia2men Sea Area. The results showed that the water samples at Station 3 (the outlet of industrial and domestic sewage of Xiamen City)and Station 4 (the major port area of Xiamen Island) were the most toxic , it would be revealed that the industrial and domesticsewage and port pollution were the major sources of pollutants. Station 8 (in the sea - route and nearby a big power plant) was lesstoxic. The toxicity at station 1 (the outlet of Western Xiamen Bay) and Station 5 (the inner port area) were the least . The resultsshowed that it was useful to test the toxicity
摘要：利用GC2ECD 和GC2MSD 对1999 年11 月闽江口水、间隙水和沉积物中的有机氯农药进行了研究. 结果显示,闽江口水中有机氯农药的含量范围是01532～1182μg/ L ,间隙水中有机氯农药的含量为4154～1317μg/ L ,沉积物(干重,以下讨论到的沉积物,无特别说明都是干重表示) :28179～52107μg/ kg ...;与其他河口如珠江口、九龙江口相比,闽江口的污染水平居中. 间隙水的污染物浓度普遍高于其上覆水的浓度,而沉积物中的浓度大于间隙水、表层水,是由于有机污染物在水体中倾向于吸附在沉积物颗粒,并且通过再悬浮从底层向上迁移. 对水体中有机氯农药各组分的含量及特征进行了分析,发现有机氯农药的主成分为:β2HCH ,DDE ,Heptachlor (七氯) ,EndosulfanⅡ(硫丹) ,Methoxychlor (甲氧滴涕) . DDE、β2HCH、Endosulfan Ⅱ分别占DDTs、HCHs 和硫丹的主要部分;有机氯农药各组分间有正相关性,表明其河口有机氯农药陆源的土壤输入与相似的环境行为;对该河口的污染水平进行了初步的评价,HCHs 符合国家海水水质一级标准,DDTs 则超过该标准.Abstract:The concentrations of 18 organochlorine pesticedes in water , pore water and surface sediment from MinjiangRiver Estuary were analyzed by GC2ECD , and confirmed by GC2MSD. The range of organochlorine pesticides was01532～1182μg/ L at water , 4154～1317μg/ L at pore water , and 28179～52107μg/ kg at sediment . Compared withthe results of other estuaries and gulfs (Pearl River Estuary , Jiulong River Estuary and so on) , it showed that the pollu2tion of organochlorines in Minjiang was some m
摘要：2000 年10 月在湄洲湾海域6 个站位采集表层沉积物样,采用GC/ MS 法分析其多环芳烃的含量. 结果显示:在这些沉积物样中,美国环保署优控的16 种多环芳烃的含量分布较为均匀,其范围为196. 7～299. 7 ng/ g ,平均值为256. 1 ng/ g ;显著低于长江口、珠江口及其欧美主要港口表层沉积物中多环芳烃的含量. 对多环芳烃特征组分的比值(菲/ 蒽比值,荧蒽/ ...芘比值) 及16 种多环芳烃中四、五和六环总含量的百分比的分析表明:湄洲湾表层沉积物的多环芳烃主要来源于燃料的高温燃烧.Abstract:The Meizhou Bay , located in the mid2east coast of Fujian , China , is a semi2enclosed narrow bayst retching deep into the inland with favorable hydrological circulation conditions. With the const ruction of port s ,oil2refinery works and power indust ry in the coastal area ,PAHs’pollution is a potential environmental risk factorin this marine environment ,but no data of PAHs level in this marine environment were established before. Theaim of this study is to examine PAHs’dist ribution in the surface sediment s and analyze their sources in theMeizhou Bay. The data showed that : PAHs’concent rations in the surface sediment s were f rom 196. 7 ～ 299. 7ng/ g and average value was 256. 1 ng/ g. The result s revealed that PAHs’pollution in the sedime
