| 摘 要： | 对羟基苯甲酸酯(parabens)作为防腐剂、防霉剂和杀菌剂等被广泛应用于食品、化妆品和药品中.近年来的研究表明,该类化合物能够在地表水体中检出,对水生生态环境存在潜在的危害.本研究于2016年秋季和冬季,对哈尔滨某典型城市污水处理厂进水进行了24 h连续采集,对6种parabens的质量浓度和4种常规水质指标进行了分析.结果表明,parabens普遍存在于城市污水中,对羟基苯甲酸甲酯、对羟基苯甲酸乙酯和对羟基苯甲酸丙酯是主要目标物,总有机碳、总溶解固体和酸碱度与parabens的浓度具有相关性;城市污水中parabens的质量浓度具有明显的日变化趋势,但是季节差异性不大.本研究结果为城市污水处理系统中parabens的深入研究和污染控制提供了重要理论依据.

| Abstract: | 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. |
