1黄铁矿产酸成分与中和酸成分的消耗及其有效成分的确定显示文摘动态浸滤法研究黄铁矿氧化产酸过程中产酸成分(AP)和中和酸成分(NP)的消耗,讨论了有效NP、AP的确定.50周实验结果表明:(1)中和酸成分NP和产酸成分AP消耗速率呈非线性变化.酸性排放(ARD)前,即pH=4前,AP、NP平均消耗速率VAP与VNP基本相同;ARD开始释放后,VAP>2VNP;(2)排放液pH<3后,Fe3+参与并加速氧化反应,AP消耗的平均速率及固溶物溶出速率提高4倍以上;(3)抑制ARD释放的有效NP<50%,控制排放液中性的有效NP<30%;引起ARD释放的有效AP>75%,且ARD将持续释放30年以上.李锦文 李晓 吴惠明 陈永亨 Basra Sohan 2011环境化学2011,30,4:4
2硫铁矿酸化过程中铊向水环境的释放迁移行为显示文摘采用动态风化模拟实验方法对来自广东某Tl污染区的硫铁矿矿样进行了2a左右持续的氧化淋滤实验,研究了硫铁矿酸化趋势及毒害金属元素铊Tl从源头向环境长期释放迁移的特征,探讨了硫铁矿酸化及Tl释放迁移的机制.结果表明:含碳酸盐硫铁矿暴露后,排放液pH值随时间呈缓慢波段下降趋势,较长时期内排放液pH>5.伴随硫铁矿酸化过程,Tl具特有的释放迁移特征.硫铁矿一旦暴露Tl就开始释放,且具强的迁移性,随后伴随风化进程呈波段减弱.在pH>5的环境中,Tl释放迁移受pH值的影响不同于酸性(pH<5)环境中,pH值降低对Tl的释放迁移没有促进作用,滤液中Tl的浓度与pH值呈正相关,还原环境有助于Tl的释放迁移.李锦文 陈南 吴惠明 常向阳 陈永亨 Basra Sohan 2012中国环境科学2012,32,6:4
3EVALUATION OF EROSION PRODUCTIVITY IMPACT CALCULATOR (EPIC) MODEL FOR MIDDLE MOUNTAIN REGION OF NEPAL显示文摘This study verifies the applicability of EPIC model for an erosion plot (61.2 m2) and anupland terraced watershed (72 ha) using a total of 94 rainfall events over a study period of two years.In order to analyze the effect of storm size on runoff and soil loss processes,rainfall events are divided into three groups:small (<25mm),moderate (25-50mm) and large (>50mm).Results indicate that the model could predict reasonably well the runoff and soil loss from the erosion plot and the watershed for the moderate and large rainfall events.However,the runoff and soil loss prediction for the small rainfall events is found to be poor.On annual basis,both surface runoffand soil loss predictions match well the observations.In light of the importance of the moderate and large rainfall events in producing most of the annual runoff and soil loss in the study area,the EPIC model is applied to assess the impacts of erosion on agricultural productivity and to evaluate management practices to protect watersheds in the middle mountainous area of Nepal.Sohan Kumar GHIMIRE Mukand Singh BABEL 2004International Journal of Sediment Research2004,19,2:4
4Wave-shaped microfluidic chip assisted point-of-care testing for accurate and rapid diagnosis of infections显示文摘Background:Early diagnosis and classification of infections increase the cure rate while decreasing complications,which is significant for severe infections,especially for war surgery.However,traditional methods rely on laborious operations and bulky devices.On the other hand,point-of-care(POC)methods suffer from limited robustness and accuracy.Therefore,it is of urgent demand to develop POC devices for rapid and accurate diagnosis of infections to fulfill on-site militarized requirements.Methods:We developed a wave-shaped microfluidic chip(WMC)assisted multiplexed detection platform(WMC-MDP).WMC-MDP reduces detection time and improves repeatability through premixing of the samples and reaction of the reagents.We further combined the detection platform with the streptavidin–biotin(SA-B)amplified system to enhance the sensitivity while using chemiluminescence(CL)intensity as signal readout.We realized simultaneous detection of C-reactive protein(CRP),procalcitonin(PCT),and interleukin-6(IL-6)on the detection platform and evaluated the sensitivity,linear range,selectivity,and repeatability.Finally,we finished detecting 15 samples from volunteers and compared the results with commercial ELISA kits.Results:Detection of CRP,PCT,and IL-6 exhibited good linear relationships between CL intensities and concentrations in the range of 1.25–40μg/ml,0.4–12.8 ng/ml,and 50–1600 pg/ml,respectively.The limit of detection of CRP,PCT,and IL-6 were 0.54μg/ml,0.11 ng/ml,and 16.25 pg/ml,respectively.WMC-MDP is capable of good adequate selectivity and repeatability.The whole detection procedure takes only 22 min that meets the requirements of a POC device.Results of 15 samples from volunteers were consistent with the results detected by commercial ELISA kits.Conclusions:WMC-MDP allows simultaneous,rapid,and sensitive detection of CRP,PCT,and IL-6 with satisfactory selectivity and repeatability,requiring minimal manipulation.However,WMC-MDP takes advantage of being a microfluidic device showing the coefficients of variation less than 10%enabling WMC-MDP to be a type of point-of-care testing(POCT).Therefore,WMC-MDP provides a promising alternative to POCT of multiple biomarkers.We believe the practical application of WMC-MDP in militarized fields will revolutionize infection diagnosis for soldiers.Bin-Feng Yin Xin-Hua Wan Ming-Zhu Yang Chang-Cheng Qian A.S.M.Muhtasim Fuad Sohan 2022Military Medical Research2022,9,5:2
