1多环芳烃污染区域氧化多环芳烃的来源、迁移转化和毒性危害显示文摘本文阐明了在对高浓度多环芳烃污染区域进行风险评估和修复过程中,氧化多环芳烃是不容忽视的重要污染物。我们通过对自己的研究成果和公开发表资料的综合分析,发现在这些地方氧化多环芳烃的量较大,但并未受到足够重视。这些氧化多环芳烃是通过多环芳烃转化而来的,滞留时间也较长。许多修复方法会加速多环芳烃的降解,从而导致在环境中的氧化多环芳烃浓度升高。此外,我们发现尽管氧化多环芳烃与通过诱变和致癌等多环芳烃常见的毒害有区别的方式产生毒性,但他们对人类和环境也是有害的。我们还有数据支持以下假说:在环境中,具有极性的氧化多环芳烃比多环芳烃稳定性差,更易通过受污染地区的地表水和地下水扩散。因此在受多环芳烃污染区域,氧化多环芳烃应该纳入监测项目当中,而其它毒性相关成分如带硝基的多环芳烃和氮杂环芳烃等则不必纳入监洲项目当中。因为氧化多环芳烃有可能在多环芳烃发生降解的时候形成,而且它们的环境行为是完全不同的,也很难通过多环芳烃浓度来预测氧化多环芳烃的含量。Staffan Lundstedt Paul A.White Christine L.Lemieux Krista D.Lynes Iain B.Lambert Larsberg Peter Haglund Mats Tysklind 王丽平 2007AMBIO-人类环境杂志2007,36,6:11
2Quality of life following laparoscopic Nissen fundoplication: Assessing short-term and long-term outcomes显示文摘AIM: To investigate the quality of life following lapa-roscopic Nissen fundoplication by assessing short-term and long-term outcomes. METHODS: From 1992 to 2005, 249 patients under-went laparoscopic Nissen fundoplication. Short-term outcome data including symptom response, side effects of surgery, endoscopy, and patient's perception of over-all success were collected prospectively. Long-term out-comes were investigated retrospectively in patients witha median follow-up of 10 years by assessment of reflux symptoms, side effects of surgery, durability of antire-flux surgery, need for additional treatment, patient's perception of success, and quality of life. Antireflux sur-gery was considered a failure based on the following criteria: moderate to severe heartburn or regurgitation; moderate to severe dysphagia reported in combination with heartburn or regurgitation; regular proton pump inhibitor medication use; endoscopic evidence of erosive esophagitis Savary-Miller grade 1-4; pathological 24-h pH monitoring; or necessity to undergo an additional surgery. The main outcome measures were short-and long-term cure rates and quality of life, with patient sat-isfaction as a secondary outcome measure. RESULTS: Conversion from laparoscopy to open sur-gery was necessary in 2.4% of patients. Mortality was zero and the 30-d morbidity was 7.6% (95%CI: 4.7%-11.7%). The median postoperative hospital stay was 2 d [interquartile range (IQR) 2-3 d]. Two hundred and forty-seven patients were interviewed for short-term analysis following endoscopy. Gastro-esophageal reflux disease was cured in 98.4% (95%CI: 95.9%-99.6%) of patients three months after surgery. New-onset dysphagia was encountered postoperatively in 13 patients (6.7%); 95% reported that the outcome was better after antireflux surgery than with preopera-tive medical treatment. One hundred and thirty-nine patients with a median follow-up of 10.2 years (IQR 7.2-11.6 years) were available for a long-term evalu-ation. Cumulative long-term cure rates were 87.7% (81.0%-92.2%) at 5 years and 72.9% (64.0%-79.9%) at 10 years. Gastrointestinal symptom rating scores and RAND-36 quality of life scores of patients with treatment success were similar to those of the general population but significantly lower in those with failed antireflux surgery. Of the patients available for long-term follow-up, 83% rated their operation a success. CONCLUSION: For the long-term, our results indicate decreasing effectiveness of laparoscopic antirefluxsurgery, although most of the patients seem to have an overall quality of life similar to that of the general population.Ilmo Kellokumpu Markku Voutilainen Caj Haglund Martti Frkkil Peter J Roberts Hannu Kautiainen 2013World Journal of Gastroenterology2013,19,24:7
3Contribution of precursor compounds to the release of per-and polyfluoroalkyl substances(PFASs) from waste water treatment plants(WWTPs)显示文摘Per-and polyfluoroalkyl substances(PFASs) are ubiquitous in sludge and water from waste water treatment plants, as a result of their incorporation in everyday products and industrial processes. In this study, we measured several classes of persistent PFASs,precursors, transformation intermediates, and newly identified PFASs in influent and effluent sewage water and sludge from three municipal waste water treatment plants in Sweden, sampled in 2015. For sludge, samples from 2012 and 2014 were analyzed as well.Levels of precursors in sludge exceeded those of perfluoroalkyl acids and sulfonic acids(PFCAs and PFSAs), in 2015 the sum of polyfluoroalkyl phosphoric acid esters(PAPs) were 15–20 ng/g dry weight, the sum of fluorotelomer sulfonic acids(FTSAs) was 0.8–1.3 ng/g,and the sum of perfluorooctane sulfonamides and ethanols ranged from non-detected to 3.2 ng/g. Persistent PFSAs and PFCAs were detected at 1.9–3.9 ng/g and 2.4–7.3 ng/g dry weight, respectively. The influence of precursor compounds was further demonstrated by an observed substantial increase for a majority of the persistent PFCAs and PFSAs in water after waste water treatment. Perfluorohexanoic acid(PFHxA), perfluorooctanoic acid(PFOA), perfluorohexane sulfonic acid(PFHxS), and perfluorooctane sulfonic acid(PFOS)had a net mass increase in all WWTPs, with mean values of 83%, 28%, 37% and 58%,respectively. The load of precursors and intermediates in influent water and sludge combined with net mass increase support the hypothesis that degradation of precursor compounds is a significant contributor to PFAS contamination in the environment.Ulrika Eriksson Peter Haglund Anna K?rrman 2017Journal of Environmental Sciences2017,29,11:5
4被多氯二苯并二恶英/呋喃以及其它多氯代芳香化合物污染土壤的处理方法显示文摘本文综述了处理被多氯代芳香化合物,尤其是被二恶英和呋喃(PCDD/Fs)污染土壤的方法。与其它土壤污染物所不同的是PCDD/Fs与土壤颗粒紧密结合,这严重削弱了大多数水处理过程的效果,也使得除传统方法以外(填埋法、固化/稳定化、原位玻璃化技术)没有几种切合实际的选择方案。焚化法的应用时间很长,并且仍是最有效的处理技术,清除效率超过99.9999%。但是超临界水氧化法、碱性催化分解法、蒸馏法和其它多种萃取技术的清除效率也可超过95%,例如溶剂和液化气体以及亚临界水提取等。这些替代技术中的很多种可能比焚化法更廉价,有可能适用于被二恶英中度污染的土壤。然而,许多方法仍然处于发展初期,需要进行更多的试验评估其真正的潜力。Peter Haglund 王大伟 2007AMBIO-人类环境杂志2007,36,6:2

15借鉴美国环保署三联体方法采用灵活的工作策略和筛选方法改进棕色地块的土壤调查显示文摘对于被污染的棕色地块(brownfield sites)及其样品的分析研究要花很多的财力,而所得的结果却常常没有很好的说服力。因此在此类研究中就需要改进研究方法来降低成本,同时提高结果的可信度。美国环境保护局所开发的三联体方法是一种能同时满足这两方面要求的方法,其核心特征是对不确定性的管理。在本文介绍的调查中,我们采用现场研究来确定一种可能的方法,运用这种方法可以在实践中管理控制不确定性。考虑的一个实例包括在特定的项目目标前提下,调整样本大小来最优化不确定性,以及在分析工作上所作的努力。此外,评价了几种毒性分析方法在筛选污染位点中的潜在效用。报道这些分析结果的同时,我们在这篇文稿中讨论了一些途径,就是怎样借鉴三联体原理将灵活的工作策略和筛选方法引入到瑞典修复棕色地块的方法中。分层次的途径充分利用了现场的和筛选的方法,其被引入到对棕色地块的评估中,集中分析了任务所要求的响应和可接受的不确定性。Christian Maurice Bjrn Gustavsson Daniel Ragnvaldsson Bjrn Rydvall Rune Berglind Peter Haglund Torbjrn Johnson Per Leffler Karin Luthbom Patrik von Heijne 陶书田 2007AMBIO-人类环境杂志2007,36,6:0
