| 1 | Simultaneous removal of ammonia and N-nitrosamine precursors from high ammonia water by zeolite and powdered activated carbon显示文摘When adding sufficient chlorine to achieve breakpoint chlorination to source water containing high concentration of ammonia during drinking water treatment, high concentrations of disinfection by-products(DBPs) may form. If N-nitrosamine precursors are present, highly toxic N-nitrosamines, primarily N-nitrosodimethylamine(NDMA), may also form. Removing their precursors before disinfection should be a more effective way to minimize these DBPs formation. In this study, zeolites and activated carbon were examined for ammonia and N-nitrosamine precursor removal when incorporated into drinking water treatment processes.The test results indicate that Mordenite zeolite can remove ammonia and five of seven N-nitrosamine precursors efficiently by single step adsorption test. The practical applicability was evaluated by simulation of typical drinking water treatment processes using six-gang stirring system. The Mordenite zeolite was applied at the steps of lime softening, alum coagulation, and alum coagulation with powdered activated carbon(PAC) sorption. While the lime softening process resulted in poor zeolite performance, alum coagulation did not impact ammonia and N-nitrosamine precursor removal. During alum coagulation, more than67% ammonia and 70%–100% N-nitrosamine precursors were removed by Mordenite zeolite(except 3-(dimethylaminomethyl)indole(DMAI) and 4-dimethylaminoantipyrine(DMAP)). PAC effectively removed DMAI and DMAP when added during alum coagulation. A combination of the zeolite and PAC selected efficiently removed ammonia and all tested seven N-nitrosamine precursors(dimethylamine(DMA), ethylmethylamine(EMA), diethylamine(DEA), dipropylamine(DPA), trimethylamine(TMA), DMAP, and DMAI) during the alum coagulation process. | Runmiao Xue Ariel Donovan Haiting Zhang Yinfa Ma Craig Adams John Yang Bin Hua Enos Inniss Todd Eichholz Honglan Shi | 2018 | Journal of Environmental Sciences2018，30，2： | 7 |
| 2 | 含高钙和维生素D的强化奶能有效提高健康的绝经后的中国女性体内的维生素D水平并减少骨吸收显示文摘目的钙摄入水平低以及体内维生素D不足是导致亚洲女性罹患骨质疏松的危险因素。此项研究的目的是评估高钙维生素D强化牛奶(HCM)对健康的中国绝经后妇女的体内维生素D状态和骨吸收标志物进行干预的影响。方法本试验对象为55岁以上,绝经至少5年的女性。共有124名女性进行了总体健康状况和骨密度检查筛选。63名女性被随机分为对照组和试验组,试验组在12w内每日饮用两次高钙/维生素D强化奶(含900 mg钙、96 mg镁、2.4 mg锌和6.4μg维生素D)。2组分别在试验开始、试验2 w、8 w和12 w时测量血矿物质、25(OH)维生素D3和Ⅰ型胶原C端肽(CTX)水平。结果对照组女性平均年龄为63±4.6岁,高钙强化奶(HCM)组女性平均年龄为62±3.8岁。所测得的每日钙摄入量的基线值为HCM组260~482 mg,对照组为252~692 mg。12 w后HCM组的平均身体质量指数(BMI)显著降低(P<0.05)。HCM组的血25(OH)维生素D3水平显著提高(33.13~39.49 nmol/L),而对照组则维持不变(29.27~28.21 nmol/L)。HCM组的血CTX水平在0 w和2 w之间下降了25%,并保持不变直至第12w。从第2w开始HCM组和对照组相比血CTX水平就出现了显著差异(P<0.001)。结论通过饮用含高钙和维生素D的强化奶(HCM),在2至4w内能显著提高中国绝经妇女体内维生素D水平,并减少骨吸收破坏。如果长期持续地饮用含高钙和维生素D的强化奶(HCM),能减少骨吸收和骨量丢失的风险,从而减少患骨质疏松和由此引起骨折的风险。 | Marlena C Kruger PengCheng Ha Joanne M Todd Barbara Kuhn-Sherlock Linda M Schollum Jiliang Ma George Qin Edith Lau | 2013 | 中国骨质疏松杂志2013，19，2： | 2 |
