含有溴离子的原水经臭氧氧化后会生成具有致癌性的溴酸盐,因此研究溴酸盐的控制对策成为饮用水处理领域的热点。通过模拟配水试验考察了新鲜活性炭向生物活性炭转化过程中对溴酸盐和有机物去除能力的变化。结果表明,活性炭滤池能有效去除溴酸盐,新炭在向生物活性炭转化的过程中滤池对溴酸盐的去除能力表现出逐渐减弱的趋势,待完全成为生物活性炭滤池后对溴酸盐的去除效果较差。不过,活性炭滤池和生物活性炭滤池对CODMn、UV254、致色有机物和CC l4都有较好的去除效果。

The dehydrogenation reaction of H2S by the ^3Σ^- ground state of VS^＋： VS^＋＋ H2S → VS2^＋＋ H2 has been studied by using Density Functional Theory （DPT） at the B3LYP/DZVP level. It is found that the reaction proceeds along two possible pathways （A and B） yielding two isomer dehydrogenation products VS2^＋-1 （^3B2） and VS2^＋-2 （^3A1）, respectively. For both pathways, the reaction has a two-step-reaction mechanism that involves the migration of two hydrogen atoms from S2 to V^＋, respectively. The migration of the second hydrogen via TS3 and that of the first via TS4 are the rate-determining steps for pathways A and B, respectively. The activation energy is 17.4 kcal/mol for pathway A and 22.8 kcal/mol for pathway B relative to the reactants. The calculated reaction heat of 9.9 kcal/mol indicates the endothermicity of pathway A and that of -11.9 kcal/mol suggests the exothermicity of pathway B.

Microorganisms capable of solubilizing and mineralizing phosphorus （P） pools in soils are considered vital in promoting P bioavallability. The study was conducted to screen and isolate inorganic P-solubilizing bacteria （IPSB） and organic P-mineralizing bacteria （OPMB） in soils taken from subtropical flooded and temperate non-flooded soils, and to compare inorganic P-solubilizing and organic P-solubilizing abilities between IPSB and OPMB. Ten OPMB strains were isolated and identified as Bacillus cereus and Bacillus megaterium, and five IPSB strains as B. megaterium, Burkholderia caryophyUi, Pseudomonas cichorii, and Pseudomonas syringae. P-solubilizing and -mineralizing abilities of the strains were measured using the methods taking cellular P into account. The IPSB strains exhibited inorganic P-solubilizing abilities ranging between 25.4-41.7 μg P mL^-1 and organic P-mineralizing abilities between 8.2-17.8μg P mL^-1. Each of the OPMB strains also exhibited both solubilizing and mineralizing abilities varying from 4.4 to 26.5 μg P mL^-1 and from 13.8 to 62.8 μg P mL^-1, respectively. For both IPSB and OPMB strains, most of the P mineralized from the organic P source was incorporated into the bacterial cells as cellular P. A significantly negative linear correlation （P 〈 0.05） was found between culture pH and P solubilized from inorganic P by OPMB strains. The results suggested that P solubilization and mineralization could coexist in the same bacterial strain.

Background: Idiopathic pulmonary fibrosis(IPF) has a poor prognosis and is often a kind of heavy financial burden to patients. Currently, few treatments are available for IPF. Clinical practice of traditional Chinese medicine(TCM), using a syndrome differentiation approach, offers some treatment success in IPF. However, there is no sufficient evidence-based study of the role of TCM in IPF management to make strong conclusions. This study evaluates the efficacy and safety of TCM in the treatment of *** and design: A multicenter, exploratory, randomized, double-blind and placebo-controlled trial is planned. A total of 80 patients will be enrolled in the study, which will include 26 weeks of *** will be randomly assigned into TCM group or control group in a 1:1 ratio. The TCM group will be given TCM granules based on syndrome differentiation. Formulae include Bao-fei Hua-xian granule for lung qi deficiency, Jin-shui Huan-xian granule for lung-kidney qi deficiency and Yang-qing Kang-xian granule for yin deficiency and inner heat. The control group will be given a corresponding TCM granule placebo. The efficacy and safety of interventions will be evaluated by the outcome variables,including frequencies of acute exacerbations, pulmonary function, clinical symptoms, dyspnea, healthrelated quality of life(HRQo L), 6-minute walk distance and safety ***: It is hypothesized that TCM will decrease the frequency of adverse events, improve pulmonary function and HRQo L, based on our clinical experience. This trial is the first study of TCM treatment in IPF that is based on syndrome differentiation and will evaluate the efficacy and safety of TCM in IPF.

目的探讨佛山市大气NO_(2)对儿童呼吸系统住院风险的急性影响。方法收集2016—2019年佛山市NO_(2)、细颗粒物等6种空气污染物每日平均浓度和平均温度、相对湿度等气象资料,及佛山市妇幼保健院每日儿童呼吸系统疾病新增住院人数(ECHR)等数据。采用时间序列分析方法,定量评估每日NO_(2)浓度对儿童呼吸系统疾病住院风险的影响。结果2016—2019年该医院平均每日儿童呼吸系统疾病新增住院人数为10人,NO_(2)、PM_(2.5)、PM_(10)、SO_(2)等日均浓度分别为42.0μg/m^(3)、35.3μg/m^(3)、58.1μg/m^(3)和11.4μg/m^(3),气压、日均气温和相对湿度分别为1008.4 Pa、23.7℃和73.3%。ECHR与NO_(2)日均浓度显著相关(r=0.079,P<0.05)。排除温湿度、星期几和时间趋势等影响因素后,在单污染物模型中,NO_(2)日均浓度每升高10μg/m^(3),在lag0和lag1,该医院ECHR的超额风险分别增加1.22%(95%CI:0.06%~2.40%)和1.37%(95%CI:0.23%~2.53%),在lag0∶7效应最强,超额风险增加1.70%(95%CI:0.12%~3.31%)。在NO_(2)+SO_(2)+CO+O_(3)_8h+PM_(2.5)和NO_(2)+SO_(2)+CO+O_(3)_8h+PM_(10)多污染物模型中,关联的显著性依然存在:在lag0、lag1和lag0∶1至lag0∶7,NO_(2)日均浓度与ECHR的关联依然显著,且均在lag0∶1关联效应最大,超额风险分别增加4.06%(95%CI:1.83%~6.34%)和3.95%(95%CI:1.85%~6.09%)。剂量反应关系分析显示NO_(2)日均浓度与ECHR基本呈线性关系,随着NO_(2)日均浓度的升高,新增住院的超额风险逐渐增加。结论在佛山市NO_(2)暴露与儿童呼吸系统疾病住院风险有显著性关联,提示政府要进一步加强空气污染防治。
