Seasonal variations in the concentrations of eight ultraviolet (UV) filters and 22 illicit drugs including their metabolites in the Korean aquatic environment were investigated. Seawater samples from three beaches, water samples from two rivers, and influents and effluents from three wastewater treatment plants were analyzed. The UV filter concentrations in the seawater, river water, and effluent samples were 39.4-296, 35.4-117, and 6.84-51.1 ng L, respectively. The total UV filter concentrations in the seawater samples were 1.9-4.4 times higher at the peak of the holiday season than outside the peak holiday season. An environmental risk assessment showed that ethylhexyl methoxy cinnamate (EHMC) could cause adverse effects on aquatic organisms in the seawater at the three beaches during the holiday period. Seven of the 22 target illicit drugs including their metabolites were detected in the wastewater influent samples, and the total illicit drug concentrations in the influent samples were 0.08-65.4 ng L. The estimated daily consumption rates for cis-tramadol (Cis-TRM), methamphetamine (MTP), meperidine (MEP), and codeine (COD) were 25.7-118.4, 13.8-36.1, 1.36-12.6, and 1.75-8.64 mg d (1000 people), respectively. In popular vacation area, the illicit drug consumption rates (Cis-TRM, MTP and MEP) were 1.6-2.6 times higher at the peak of the summer holiday season than at the beginning of the summer.
研究了韩国水环境中八种紫外线 (UV) 过滤器和二十二种非法药物（包括其代谢物）浓度的季节性变化。分析了三个海滩的海水样本、两条河流的水样以及三个污水处理厂的进水和出水。海水、河水和污水中的 UV 过滤器浓度分别为 39.4-296、35.4-117 和 6.84-51.1ng/L。海水样本中 UV 过滤器浓度在假期高峰期是非高峰期的 1.9-4.4 倍。环境风险评估显示，在假期期间，三个海滩的海水中，乙基己基甲氧基肉桂酸 (EHMC) 可能对水生生物产生不利影响。在污水进水样本中检测到二十二种目标非法药物中的七种及其代谢物，进水样本中的总非法药物浓度为 0.08-65.4ng/L。顺式曲马多 (Cis-TRM)、甲基苯丙胺 (MTP)、哌替啶 (MEP) 和可待因 (COD) 的估计日消耗量分别为 25.7-118.4、13.8-36.1、1.36-12.6 和 1.75-8.64mg/d(1000 人)。在热门度假区，夏季假期高峰期非法药物（Cis-TRM、MTP 和 MEP）的消耗率比夏季开始时高 1.6-2.6 倍。
