dc.description.abstract采用戊基化格式衍生法,gC-fPd分析了厦门港周边海域9个小岛屿分布的疣荔枝螺(THAIS ClAVIgErA)体内3种丁基锡化合物(buTylTInS)和3种苯基锡化合物(PHEnylTInS)的存在形态与分布特征.结果表明,丁基锡化合物总浓度(ΣbTS)为0.3~70.6ng.g-1,平均值为28.8ng.g-1,以一丁基锡化合物(MbT)为主.苯基锡化合物总浓度(ΣPHTS)为nd~18.8ng.g-1,平均值为7.9ng.g-1,以三苯基锡化合物为主.厦门港周边海域以丁基锡化合物为主要污染物,占到总有机锡化合物(ΣOTS)的74.3%~96.8%.疣荔枝螺体内(ΣbTS)和(ΣPHTS)呈现从厦门港内到港外逐渐降低的趋势.疣荔枝螺体内TbT和TPHT的浓度显示良好的相关关系(r2=0.7109,P<0.01),说明TPHT和TbT来源趋同,即来源于船舶防污涂料,或水产养殖污染源.与我国东南沿海港口相比,厦门海域疣荔枝螺体内丁基锡化合物的污染处于一个较低水平但比2002年有所加重.
dc.description.abstractOccurrence and distribution of 6 organotin compounds including butyltin and phenyltin species were detected in Thais clavigera which were collected from 9 coastal areas sites around Xiamen Coast,by pentylized derivatization,GC-FPD.Results indicated that all Thais clavigera samples were contaminated with organotin compounds.The concentrations in Thais clavigera soft bodies varied from 0.3 to 70.6 ng.g -1 with a mean value of 28.8 ng.g -1 for butyltin compounds,and from nd to 18.8 ng.g -1 with a mean value of 7.9 ng.g -1 for phenyltin compounds,respectively.MBT and TPhT were high levels in butyltin compounds and phentyltin compounds,respectively.In addition,butyltin compounds were the dominant contaminates in all samples with high percentage from 74.3% to 96.8%.There was a significant correlation between TBT and TPhT (R2 = 0.710 9,p < 0.01).This result showed that both TBT and TPhT came from antifouling paints for ships or for mariculture nets.Compared with those data reported from the other regions around southeast coast of China,present study reveals that contaminated level of organotin compounds in Thais clavigera are relatively lower in Xiamen Coast.But it is higher than those in 2002.
