Parabens are widely used in foodstuffs, cosmetics, and pharmaceuticals as preservatives, fungicides, and bactericides. Recent studies showed that these compounds could be detected in surface water and are a potential hazard to the aquatic ecological environment. In this study, 24-hour influent samples were collected from a typical sewage wastewater treatment plant in Harbin in autumn and winter in 2016. The concentrations of six parabens and four normal water quality parameters were analyzed. The results indicated that parabens were frequently detected in the influent, and MeP, EtP, and PrP were the predominant compounds. Significant correlations were found between TOC, TDS, pH, and the concentration of parabens. The concentration of parabens in the influent of the sewage wastewater treatment plant have obvious daily variations rather than seasonal variations. The results provide an important theoretical basis for further research and pollution control of parabens in sewage wastewater treatment system.
对羟基苯甲酸酯作为防腐剂、杀菌剂和消毒剂广泛应用于食品、化妆品及药品中。近期研究表明，这些化合物可在地表水中被检测到，对水生生态环境构成潜在威胁。本研究于2016年秋冬季节从哈尔滨某典型污水处理厂采集了24小时进水样本，分析了六种对羟基苯甲酸酯的浓度及四项常规水质参数。结果表明，进水样本中经常检测到对羟基苯甲酸酯，其中甲基对羟基苯甲酸酯、乙基对羟基苯甲酸酯和丙基对羟基苯甲酸酯为主要化合物。总有机碳、总溶解固体、pH值与对羟基苯甲酸酯浓度之间存在显著相关性。污水处理厂进水的对羟基苯甲酸酯浓度呈现明显的日变化而非季节变化。研究结果为进一步研究污水处理系统中对羟基苯甲酸酯以及污染控制提供了重要的理论依据。
