Arsenic geochemistry of groundwater in Southeast Asia

Kyoung-Woong Kim, Penradee Chanpiwat, Hoang Thi Hanh, Kongkea Phan, Suthipong Sthiannopkao

《医学前沿（英文）》 2011年第5卷第4期页码 420-433 doi: 10.1007/s11684-011-0158-2

摘要： The occurrence of high concentrations of arsenic in the groundwater of the Southeast Asia region has received much attention in the past decade. This study presents an overview of the arsenic contamination problems in Vietnam, Cambodia, Lao People’s Democratic Republic and Thailand. Most groundwater used as a source of drinking water in rural areas has been found to be contaminated with arsenic exceeding the WHO drinking water guideline of 10 μg·L . With the exception of Thailand, groundwater was found to be contaminated with naturally occurring arsenic in the region. Interestingly, high arsenic concentrations (>10 μg·L ) were generally found in the floodplain areas located along the Mekong River. The source of elevated arsenic concentrations in groundwater is thought to be the release of arsenic from river sediments under highly reducing conditions. In Thailand, arsenic has never been found naturally in groundwater, but originates from tin mining activities. More than 10 million residents in Southeast Asia are estimated to be at risk from consuming arsenic-contaminated groundwater. In Southeast Asia, groundwater has been found to be a significant source of daily inorganic arsenic intake in humans. A positive correlation between groundwater arsenic concentration and arsenic concentration in human hair has been observed in Cambodia and Vietnam. A substantial knowledge gap exists between the epidemiology of arsenicosis and its impact on human health. More collaborative studies particularly on the scope of public health and its epidemiology are needed to conduct to fulfill the knowledge gaps of As as well as to enhance the operational responses to As issue in Southeast Asian countries.

Yaojun GE, Shuyang CAO, Xinyang JIN

《结构与土木工程前沿（英文）》 2013年第7卷第4期页码 402-410 doi: 10.1007/s11709-013-0230-x

摘要： This paper reviews wind loading codes and standards in the Asia-Pacific Region, in particular in the 15 countries and areas. A general description of wind loading model is given as a famous wind loading chain described by four variables including velocity pressure, exposure factor, pressure coefficient, and gust response factor. Through the APEC-WW Workshops and the extensive calculations for three examples of low, medium and high rise buildings, these four important variables of wind loads are evaluated and compared with statistical parameters, mean values and coefficients of variation. The main results of the comparison show some differences among the 15 economies, and the reasons and further incorporation are discussed and suggested.

HUANG Jinliang, HONG Huasheng, ZHANG Luoping

《环境科学与工程前沿（英文）》 2008年第2卷第3期页码 333-339 doi: 10.1007/s11783-008-0035-7

摘要： This paper presents the study carried out for controlling agricultural non-point source pollution (NSP) in a medium-sized watershed covering 1.47 × 10 km in Southeast China using quantitative analysis coupled with geographic information system (GIS), universal soil loss equation (USLE), soil conservation service-curve number (SCS-CN), nutrient loss equations, and annualized agricultural nonpoint source model (AnnAGNPS). Based on the quantitative results derived from GIS and environmental models, five control division units were generated for NSP control in Jiulong River watershed, namely, controlling unit for soil losses, controlling unit for livestock breeding and soil losses, controlling unit for excessive fertilizer use and livestock breeding, controlling unit for soil losses and fertilizer use, and controlling unit for excessive fertilizer use and soil losses. This study proved that integrating GIS with environmental models can be adopted to efficiently evaluate major sources and contributors of NSP, and identify the critical source areas of NSP, which enables adjusting measures to local conditions by further control division units developed through such study for control and management of water quality degradation induced by NSP in the Jiulong River watershed.

ClimateAP: an application for dynamic local downscaling of historical and future climate data in Asia

Tongli WANG, Guangyu WANG, John L. INNES, Brad SEELY, Baozhang CHEN

《农业科学与工程前沿（英文）》 2017年第4卷第4期页码 448-458 doi: 10.15302/J-FASE-2017172

摘要： While low-to-moderate resolution gridded climate data are suitable for climate-impact modeling at global and ecosystems levels, spatial analyses conducted at local scales require climate data with increased spatial accuracy. This is particularly true for research focused on the evaluation of adaptive forest management strategies. In this study, we developed an application, ClimateAP, to generate scale-free (i.e., specific to point locations) climate data for historical (1901–2015) and future (2011–2100) years and periods. ClimateAP uses the best available interpolated climate data for the reference period 1961–1990 as baseline data. It downscales the baseline data from a moderate spatial resolution to scale-free point data through dynamic local elevation adjustments. It also integrates and downscales the historical and future climate data using a delta approach. In the case of future climate data, two greenhouse gas representative concentration pathways (RCP 4.5 and 8.5) and 15 general circulation models are included to allow for the assessment of alternative climate scenarios. In addition, ClimateAP generates a large number of biologically relevant climate variables derived from primary monthly variables. The effectiveness of the local downscaling was determined based on the strength of the local linear regression for the estimate of lapse rate. The accuracy of the ClimateAP output was evaluated through comparisons of ClimateAP output against observations from 1805 weather stations in the Asia Pacific region. The local linear regression explained 70%–80% and 0%–50% of the total variation in monthly temperatures and precipitation, respectively, in most cases. ClimateAP reduced prediction error by up to 27% and 60% for monthly temperature and precipitation, respectively, relative to the original baselines data. The improvements for baseline portions of historical and future were more substantial. Applications and limitations of the software are discussed.

null

《医学前沿（英文）》 2016年第10卷第4期页码 430-436 doi: 10.1007/s11684-016-0492-5

摘要：

Acquired thrombotic thrombocytopenic purpura (TTP) is a rare life-threatening thrombotic microangiopathy. This study aimed to provide a profile of the diagnosis and management of patients with acquired TTP collected in 10 years in a single center in southeast China. A total of 60 patients diagnosed with acute acquired TTP from March 2005 to August 2015 were enrolled. Among the 60 patients, 52 patients presented with their first episodes, and eight patients had two or more episodes. The median age at presentation was 49 (range, 17 to 78) years with a female predominance (male:female ratio, 1:1.60). ADAMTS 13 activity were analyzed in 43 patients, among whom 33 (76.7%) patients had a baseline level of<5%. Mortality was 30%. Plasma exchange (PEX) was performed in 62 of 69 (89.9%) episodes. Corticosteroids were administered in 54 of 69 (78.3%) episodes. Other immunosuppressants (e.g., vincristine, cyclosporine, and cyclosporin) were used in 7 of 69 (10.1%) episodes. Rituximab was documented in 4 patients with refractory/relapsed TTP for 5 episodes, showing encouraging results. In conclusion, the diagnosis of TTP depended on a comprehensive analysis of clinical data. Plasma ADAMTS13 activity assay helped confirm a diagnosis. PEX was the mainstay of the therapy, and rituximab can be used in relapsed/refractory disease.

Problems of Syrdarya river basin management

Serdar EYEBERENOV, Baijing CAO, Fengting LI

《环境科学与工程前沿（英文）》 2009年第3卷第2期页码 221-225 doi: 10.1007/s11783-009-0015-6

摘要： Prior to independence, Central Asian countries were closely interconnected through the regional management incorporating water, energy, and food sectors. This approach, supported by the central government of Union of Soviet Socialist Republics (USSR), functioned effectively – meeting the needs of both upstream and downstream countries. However, after independence, Central Asian countries started prioritizing their own economic development policies without due account to regional concerns such as joint use of water resources, leading to instability. In this study, the case of Syrdarya basin was investigated to show how such strategies create tension in the region, since primary focus is given to national interests, without consideration for regional problems. To address this issue, an integrated approach to incorporating water, energy, and agriculture is needed. It is suggested that a single sector approach on water alone does not lead to stability, and a multi-sectoral approach is necessary to ensure sustainable development. Countries sharing benefits from the river have to be responsible for costs of operation and maintenance of the water facilities.

摘要： This study investigated the molecular types of the species complex isolates and their clinical manifestations among human immunodeficiency virus (HIV)-positive and HIV-negative patients in southeast China in the past 15 years. The molecular types of 109 isolates from 108 patients were analyzed by the PCR fingerprinting method, sequences of internal transcribed spacers of rDNA (ITS region), and sequences of the capsule-associated gene (). In HIV-positive patients, clinical isolates were grouped into molecular types VNI (75%, 15/20), VNII (15%, 3/20), and VNIII (10%, 2/20). In HIV-negative patients, the majority of the clinical isolates were grouped into molecular types VNI (72%, 64/89), VNII (13%, 12/89), VGI (12%, 11/89), VNIII (1%, 1/89), and VGII (1%, 1/89). In reference to the mating type of the isolates, 97% (106/109) were of the α, 2% (2/109) were of the α/- and 1% (1/109) were of theα/. As for the clinical manifestations of the molecular types among the patients, the average cerebrospinal fluid (CSF) pressure of the patients infected by the was higher than that of the patients infected by the . These results suggest that both HIV-positive and HIV-negative cryptococcal patients in the southeast of China are mostly infected by the strains. No strains were found in HIV-positive patients.

摘要：

耦合模式比较计划（CMIP）是气候模拟研究领域的重要国际合作平台，服务于气候模式比较、气候变率、气候预测和气候预估。改善气候模式在东亚和西北太平洋地区的模拟性能，一直是气候模式领域面临的一项挑战。针对第五次耦合模式比较计划（CMIP5）中的气候模式，本文提供了综合鲁棒性分析。本文从气候平均态、年际变率、中上新世（MP）和过去千年的历史气候变化、气候预估的角度，对CMIP5 模式的优缺点进行了评估。另外，还评估了区域气候模式相对于驱动其运行的全球气候模式带来的模拟增值。从CMIP3 到CMIP5，模式的可信度明显提高，气候平均态、年际变率和过去气候变化的模拟情况有所改善，但在CMIP5 模式中，一些之前已知的偏差，如西北太平洋副热带高压脊线的位置和与之相关的降水偏差等，仍然很明显。对于年际振幅的模拟也存在明显的缺陷，如厄尔尼诺- 南方涛动（ENSO）与季风的关系。在模拟平均气候态和年际变率时，耦合模式的表现通常优于单独大气模式。多模式比较的结果表明，尽管在克劳修斯- 克拉珀龙方程约束下模式预估的降水一致增加，但未来气候预估仍存在明显的不确定性。对东亚- 西北太平洋地区的动力降尺度预估而言，区域海洋- 大气耦合模式是一个较好的选择。
