| 1 | 城市污水再生处理反渗透系统RO浓水的水质特征显示文摘文章系统总结和分析了城市污水再生处理反渗透(m WRRO)系统RO浓水中的化学污染物的来源与特点。结果表明,RO浓水中的COD、DOC、NH3-N、NO3^-和PO4^3-可分别达60~184、19.2~62、0.3~37.5、3.1~296和10~39 mg/L,m WRRO的水源水质、RO操作参数及其回收率的差异导致了RO浓水的水质变化较大。m WRRO工艺运行过程中投加的多种化学药剂使得RO浓水中存在高浓度的无机盐和阻垢剂等化学物质。除了常规水质指标外,m WRRO系统RO浓水中存在高风险有毒物质如药物及个人护理用品(PPCPs),内分泌干扰物(EDCs)和消毒副产物(DBPs)等。有研究检出RO浓水存在多种PPCPs,如卡马西平、碘美普尔和萘普生的浓度可分别高达3.4、3.9和9.22μg/L。m WRRO系统进水的氯化消毒,会导致工艺运行过程中卤代以及亚硝胺类DBPs的生成。 | 孙迎雪 胡洪营 汤芳 高岳 李昂 | 2015 | 环境科学与技术2015,38,1: | 10 |
| 2 | 消费品中的环境内分泌干扰物(EDCs)及其对健康的危害显示文摘环境内分泌干扰物(EDCs)是一类化学品,可以冒充天然激素,混进人和动物的内分泌系统,模仿、阻断或干扰天然激素而引起内分泌紊乱,造成人类和动物体内内分泌失调、生殖能力下降、发育失衡,甚至引发恶性肿瘤和生物绝种。环境内分泌干扰物种类很多,已经确定的有邻苯二甲酸酯类、重金属类、双酚A以及溴化阻燃剂等。本文综述了近年来消费品中环境内分泌干扰物对健康危害作用的研究进展,主要包括环境内分泌干扰物的种类、环境内分泌干扰物在消费品中的分布,及其对人类健康的危害等研究进展。 | 姜宪娟 王丽虹 许征 刘胜 苗贵东 | 2018 | 检验检疫学刊2018,28,6: | 8 |

| 5 | Investigation on removal pathways of Di 2-ethyl hexyl phthalate from synthetic municipal wastewater using a submerged membrane bioreactor显示文摘Highly hydrophobic Di 2-ethyl hexyl phthalate(DEHP) is one of the most prevalent plasticizers in wastewaters. Since its half-life in biological treatment is around 25 days, it can be used as an efficiency indicator of wastewater treatment plant for the removal of hydrophobic emerging contaminants. In this study, the performance of submerged membrane bioreactor was monitored to understand the effect of DEHP on the growth of aerobic microorganisms. The data showed that the chemical oxygen demand(COD)and ammonia concentration were detected below 10 and 1.0 mg/L, respectively for operating conditions of hydraulic retention time(HRT) = 4 and 6 hr, sludge retention time(SRT) = 140 day and sludge concentration between 11.5 and 15.8 g volatile solid(VS)/L. The removal efficiency of DEHP under these conditions was higher and ranged between 91% and 98%. Results also showed that the removal efficiency of DEHP in biological treatment depended on the concentration of sludge, as adsorption is the main mechanism of its removal. For the submerged membrane bioreactor, the pore size is the pivotal factor for DEHP removal, since it determines the amount of soluble microbial products coming out of the process. Highly assimilated microorganisms increase the biodegradation rate, as 74% of inlet DEHP was biodegraded; however, the concentration of DEHP inside sludge was beyond the discharge limit. Understanding the fate of DEHP in membrane bioreactor,which is one of the most promising and futuristic treatment process could provide replacement for conventional processes to satisfy the future stricter regulations on emerging contaminants. | Mehdi Zolfaghari Patrick Drogui Brahima Seyhi Satinder Kaur Brar Gerardo Buelna Rino Dubé Nouha Klai | 2015 | Journal of Environmental Sciences2015,27,11: | 2 |
| 6 | Photo enhanced degradation of contaminants of emerging concern in waste water显示文摘Emerging contaminants are posing serious global threats to the environment due to their diversity,recalcitrant nature and bioaccumulation.More disturbing is the fact that current wastewater treatment systems do not have the capacity to deal with these class of compounds.The quest to develop new technologies to mitigate the adverse effects of these contaminants has engendered new research interest on photo-enhanced processes.Photo-enhanced processes,with the potential of mineralizing environmental pollutants,currently appears to be the main viable technology for dealing with emerging contaminants.The process of contaminant degradation could either proceed via oxidation or reduction routes,referred to as advanced oxidation processes(AOPs)and advanced reduction processes(ARPs)respectively.Recently,different processes have been incorporated into a single system in order to explore the synergy that ensue from the combination of these processes.These processes that are currently at the front line in dealing with various classes of emerging contaminants,whose presence in the environment continues to grow on a daily basis,are the focus of this review. | Olalekan C.Olatunde Alex T.Kuvarega Damian C.Onwudiwe | 2020 | Emerging Contaminants2020,6,1: | 1 |
| 7 | 市政尾水中环境雌激素对水生态健康的影响显示文摘市政尾水含有多种已知及未知生态健康风险污染物,排放到环境后可能对受纳水体生态系统健康产生威胁,特别是尾水中环境雌激素(EEs)因会干扰生物体生殖、免疫及神经系统而备受关注。此外,EEs可在生物体内蓄积,影响生物种群组成,进而对水生态健康造成潜在威胁。从市政尾水中EEs的种类、浓度水平、对受纳水体中水生生物的危害以及其在受纳水环境中迁移转化的规律等角度,综述了近年来市政尾水中EEs对受纳水体水质影响的研究进展,指出了现有研究的不足,并对未来的研究方向进行了展望。结果表明:市政尾水中EEs浓度在ng/L级别,对受纳水体中水生生物健康存在内分泌干扰等效应;同时对水生生态系统结构和功能产生不利影响。受纳水体中EEs的迁移转化规律受到水文水质条件变化、光降解及生物降解等因素的影响,但是目前针对EEs在受纳水体中的生物毒性时空变化规律及其影响因素的相关研究较少。该研究结果可为开展市政尾水对受纳水体的生态健康风险评价提供参考。 | 苏贝 张琳钰 陈玲 余静 吴兵 | 2022 | 安全与环境工程2022,29,5: | 1 |
| 8 | 内分泌干扰物对鱼类跨世代毒性效应及机制的研究进展显示文摘目前的研究对于内分泌干扰物(endocrine disrupting chemicals,EDCs)暴露人类和野生动物所引起的毒性危害已有较为深入的科学认识。然而,近年来的研究发现,EDCs引起的亲代生理功能异常会传递给子代,即产生跨世代毒性效应,即使子代没有直接受到暴露,但其存活、生长、发育、生理、内分泌系统和行为等功能仍然也会受到严重影响。不同于已有的许多综述主要总结了EDCs对亲本产生的毒性危害,本文针对鱼类这一重要的生态毒理学研究模型,全面归纳了EDCs分别经母本、父本和双亲引起跨世代毒性效应的最新研究进展,并从EDCs的跨世代传递、内分泌激素和其他生理因子的跨世代传递以及表观遗传修饰的跨世代继承这3个方面,综述了EDCs对鱼类产生跨世代毒性效应的作用机制,以期为全面认识EDCs的生态风险提供参考。 | 赵飞 杨艳羽 汝少国 陈栋 施雪卿 魏朋浩 | 2022 | 生态毒理学报2022,17,4: | 0 |
| 9 | 邻苯二甲酸酯及Wnt通路影响配子及胚胎发育的研究进展显示文摘邻苯二甲酸酯(PAEs)作为添加剂被广泛应用于食品、建材、医疗等各行各业中。由于PAEs难以形成强力的共价键,PAEs会不断泄露到环境中并通过人们的饮食、日常生活用品接触等在人体中蓄积。作为环境内分泌干扰物中的一大类,PAEs会造成影响深远的生殖内分泌干扰效应,对配子及胚胎发育产生影响。而Wnt家族基因及其产物可通过多环节、多作用位点影响基因表达或促进细胞增殖,从而诱导组织分化来调控生长发育。综述PAEs的生化性质和污染途径以及PAEs的内分泌干扰机制,并综述Wnt及其他可能介导PAEs对配子及胚胎发育造成影响的信号通路或机制。 | 汪晨曦 黄巧瑶 马天仲 | 2019 | 国际生殖健康/计划生育杂志2019,38,4: | 0 |
