The pharmaceutical residues in waste water from the largest sewage treatment plant (STP) in Northern Taiwan and in seawater around the effluent discharged area were determined. An environmental risk assessment for the marine environment was conducted based on the environment risk quotient (ERQ). The concentrations of the analyzed compounds in STP influent and effluent were generally higher than those found in coastal seawater. Relatively higher values were found at the estuarine mouth and the discharged area, suggesting that the STP effluent is a point source. The removal efficiency and half life of the analyzed compounds were 6.3-46.8% and 3-18 days, respectively. The ERQ value theoretical calculation was generally greater than 1. However, when the measured concentrations replaced the predicated concentrations, the ERQ values were considerably lower than 1. Therefore, our results call for a re-evaluation of the risks posed by pharmaceuticals to coastal marine ecosystems in Northern Taiwan.
测定了台湾北部最大污水处理厂（STP）废水中以及排放口周围海水中的药物残留。根据环境风险商（ERQ）对海洋环境进行了环境风险评估。STP 进水和出水的分析物浓度通常高于沿海海水的浓度。在河口和排放区发现了相对较高的值，表明 STP 出水是一个点源。分析物的去除效率和半衰期分别为 6.3-46.8%和 3-18 天。理论计算的 ERQ 值通常大于 1。但是，当用实测浓度代替预测浓度时，ERQ 值明显小于 1。因此，我们的研究结果表明，需要重新评估药物对台湾北部沿海海洋生态系统造成的风险。
