为揭示辽东湾近海海域环境内分泌干扰物(EDCs)的生物效应与潜在生态风险,利用组织学方法系统调查辽东湾近海海域野生四角蛤蜊性畸变发生情况,并利用GC-MS/MS分析了组织体内典型酚类污染物包括壬基酚(NP)、辛基酚(Op)和双酚A(BPA)的浓度水平.调查结果表明：5月、6月和8月野生四角蛤蜊雌雄同体发生率分别为30%,20%和14%,软体部组织中 NP 浓度则分别为410.70,254.95,227.15ng/g dw(干重), BPA浓度分别为7.60,4.30,7.05ng/gdw,但是没有检出OP.研究结果表明环境EDCs已经影响了辽东湾海洋生物繁殖系统、并对区域海洋生态系统造成潜在风险.

To evaluate the biological effects and the potential risk on marine invertebrate exposure to the endocrine disrupting chemicals (EDCs) in Liaodong Bay, the intersex of wild Mactra veneriformis were investigated. At the same time, the typical phenols contaminations including nonylphenols (NP), octylphenol (OP) and bisphenol-A (BPA) in soft tissues were detected using GC-MS/MS. The results showed that the incidences of intersex were 30%, 20% and 14%collected from May, June and August, respectively. Corresponding to the three samplings, the concentrations of NP in soft tissue were 410.70, 254.95, 227.15ng/g dry weight (dw), and the BPA were 7.60, 4.30 and 7.05 ng/gdw, but no OP was detected in all samples. The above results suggested that the EDCs have already affected marine organism reproductive system and might play a potential risk to the marine ecosystem in Liaodong Bay.
