【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GC MS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。更多还原

【Abstract】 Cultured zygotes of Plectorhinchus cinctus were done to make test the toxicity of surface water samples in Western Xiamen 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 domestic sewage and port pollution were the major sources of pollutants. Station 8(in the sea-route and nearby a big power plant) was less toxic. The toxicity at station 1 (the outlet of Western Xiamen Bay) and Station 5 (the inner port area) were the least. The results showed that it was useful to test the toxicity of water samples by the method. Simultaneously sixteen components of EPA priority PAHs in these samples were also measured by GC/MS (SIM mode). The sequence of the toxicity to zygotes and the sequence of the concentrations of total PAHs were not the same, since the factors influencing the toxicity to zygotes were complicated, it would be also revealed that the method was useful to indicate the total marine environment quality.更多还原
