Abstract: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.
