在韩国最大的工业城市蔚山的5个污水处理厂（WWTPs）调查了20种药物和个人护理产品（PPCPs）的发生和去除效率，包括抗生素、激素和其他几种杂项药物（镇痛药、抗癫痫药、降脂药、降压药、防腐剂和兴奋剂）。采用固相萃取法（SPE）从废水样品中提取化合物，并采用高效液相色谱-串联质谱（HPLC-MS/MS）对其进行分析。结果表明，对乙酰氨基酚、阿替洛尔和林可霉素是污水中主要的单项污染物，浓度均在10 μ g/L以上。在WWTPs中，镇痛药对乙酰氨基酚、兴奋剂咖啡因、激素雌三醇和雌二醇的浓度下降了99%以上。相反，抗生素磺胺乙嗪、降压药美托洛尔和抗癫痫药卡马西平的去除率低于30%。特别是，抗生素的去除率在-11.2到69%之间变化。在一级处理（物理化学过程）中，药物的去除微不足道（高达28%），大部分药物的去除发生在二级处理（生物过程）中。在缺氧-缺氧共存条件下，改性活性污泥法对林可霉素、卡马西平、阿替洛尔、美托洛尔和三氯生的去除率较好。有必要对生物过程的设计和操作方面进行进一步调查，以便有效地去除ppcp，特别是抗生素，以确保下游接收的健康水资源，从而确保可持续的水循环管理。(C) 2011年Elsevier B.V.出版
Occurrence and removal efficiencies of 20 pharmaceuticals and personal care products (PPCPs) including antibiotics, hormones, and several other miscellaneous pharmaceuticals (analgesics, antiepileptics, antilipidemics, antihypertensives, antiseptics, and stimulants) were investigated in five wastewater treatment plants (WWTPs) of Ulsan, the largest industrial city of Korea. The compounds were extracted from wastewater samples by solid-phase extraction (SPE) and analyzed by High-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). The results showed that acetaminophen, atenolol and lincomycin were the main individual pollutants usually found in concentrations over 10 mu g/L in the sewage influent. In the WWTPs, the concentrations of analgesic acetaminophen, stimulant caffeine, hormones estriol and estradiol decreased by over 99%. On the contrary, the antibiotic sulfamethazine, the antihypertensive metoprolol, and the antiepileptic carbamazepine exhibited removal efficiencies below 30%. Particularly, removal of antibiotics was observed to vary between -11.2 and 69%. In the primary treatment (physicochemical processes), the removal of pharmaceuticals was insignificant (up to 28%) and removal of majority of the pharmaceuticals occurred during the secondary treatment (biological processes). The compounds lincomycin, carbamazepine, atenolol, metoprolol, and triclosan showed better removal in WWTPs employing modified activated sludge process with co-existence of anoxic-oxic condition. Further investigation into the design and operational aspects of the biological processes is warranted for the efficient removal of PPCPs, particularly antibiotics, to secure healthy water resource in the receiving downstream, thereby ensuring a sustainable water cycle management.
