Coastal ecosystems are receiving environments for micropollutants due to high levels of associated anthropogenic activities. Effluent discharges from wastewater treatment plants are a significant source of micropollutants to coastal environments. Wastewater effluents, seawater, sediments, and green-lipped mussels (Perna canaliculus) in Lyttelton Harbour (Te Whakaraupō), Christchurch, New Zealand, were analysed for a suite of personal care products and steroid hormones during a 1-year period. In wastewater effluents, the concentration of methyl paraben (mParaben), ethyl paraben (eParaben), propyl paraben (pParaben), butyl paraben (bParaben), 4-t-octylphenol (OP), 4-methylbenzylidene camphor (4-MBC), benzophenone-3 (BP-3), benzophenone-1 (BP-1), triclosan, methyl triclosan (mTric), Bisphenol A (BPA), Estrone (E1), 17β-estradiol (E2), 17α-ethinyl estradiol (EE2), and Estriol (E3) ranged from < 0.6 to 429 ng L−1 and was dominated by OP, 4-MBC, BP-3, triclosan, BP-1, and BPA. In seawater, 4-MBC, BP-3, BPA, and E1 were the most frequently detected contaminants (< 0.2–9.4 ng L−1). Coastal sediment samples contained mParaben, OP, 4-MBC, BP-3, BP-1, BPA, OMC, and E1 (< 0.2–11 ng g−1 d.w.), and mParaben, OP, and BP-3 were found to bioaccumulate (3.8–21.3 ng g−1 d.w.) in green lipped mussels.

新西兰利特尔顿港(TeWhakaraupō)废水和接收的沿海水域,沉积物和生物区系中的有机微量污染物

由于高水平的相关人为活动,沿海生态系统正在接受微污染物的环境。废水处理厂的废水排放是向沿海环境排放微污染物的重要来源。在1年的时间里,对新西兰克赖斯特彻奇Lyttelton Harbor(TeWhakaraupō)的废水,海水,沉积物和青唇贻贝(Perna canaliculus)进行了一系列个人护理产品和类固醇激素的分析。在废水中,对羟基苯甲酸甲酯(mParaben),对羟基苯甲酸乙酯(eParaben),对羟基苯甲酸丙酯(pParaben),对羟基苯甲酸丁酯(bParaben)的浓度为4- t-辛基苯酚(OP),4-甲基亚苄基樟脑(4-MBC),二苯甲酮3(BP-3),二苯甲酮1(BP-1),三氯生,甲基三氯生(mTric),双酚A(BPA),雌酮( E1),17β-雌二醇(E2),17α-乙炔基雌二醇(EE2)和雌三醇(E3)的范围在<0.6至429 ng L -1之间,并以OP,4-MBC,BP-3,三氯生,BP为主-1和BPA。在海水中,4-MBC,BP-3,BPA和E1是最常见的污染物(<0.2–9.4 ng L -1)。沿海沉积物样品包含mParaben,OP,4-MBC,BP-3,BP-1,BPA,OMC和E1(<0.2-11 ng g -1  dw),并且发现mParaben,OP和BP-3 在青唇贻贝中生物富集(3.8–21.3 ng g -1 dw)。
