International Journal of Environmental Research and Public Health Article Spatial Analysis of Human Health Risk Due to Arsenic Exposure through Drinking Groundwater in Taiwan’s Pingtung Plain Ching-Ping Liang 1, Yi-Chi Chien 2, Cheng-Shin Jang 3, Ching-Fang Chen 4 and Jui-Sheng Chen 4,* 1 Department of Nursing, Fooyin University, Kaohsiung 831, Taiwan; [email protected] 2 Department of Environmental Engineering and Science, Fooyin University, Kaohsiung 831, Taiwan; [email protected] 3 Department of Leisure and Recreation Management, Kainan University, Taoyuan 338, Taiwan; [email protected] 4 Graduate Institute of Applied Geology, National Central University, Taoyuan 320, Taiwan; [email protected] * Correspondence: [email protected]; Tel.: +886-3-280-7427; Fax: +886-3-426-3127 Academic Editor: Howard W. Mielke Received: 28 October 2016; Accepted: 10 January 2017; Published: 14 January 2017 Abstract: Chronic arsenic (As) exposure continues to be a public health problem of major concern worldwide, affecting hundreds of millions of people. A long-term groundwater quality survey has revealed that 20% of the groundwater in southern Taiwan’s Pingtung Plain is clearly contaminated with a measured As concentration in excess of the maximum level of 10 µg/L recommended by the World Health Organization. The situation is further complicated by the fact that more than half of the inhabitants in this area continue to use groundwater for drinking. Efforts to assess the health risk associated with the ingestion of As from the contaminated drinking water are required in order to determine the priorities for health risk management. -

Vision Environmental Engineering Corporation (PVEEC), Taipei, Taiwan Correspondence: Cheh-Shyh Ting ([email protected]) Published: 27 April 2020 Abstract. Taiwan is an oceanic nation with an area of approximately 36 000 km2. The Central Mountain Range was formed by the Eurasian and Philippine plates and stretches along the entire island from north to south, along the entire island, thus forming a natural line of demarcation for rivers on the eastern and western sides of the island. Pingtung Plain is formed by Quaternary alluvial fan material from the three main rivers. The aquifers comprise very coarse permeable sands and gravels under phreatic conditions in the north and less permeable sands under confined or even artesian conditions in the southern part of Pingtung Plain. The natural groundwater source is mainly from direct rainfall percolation and infiltration from the three main rivers, with their catchments lying partly outside the plain. The uncontrolled development of groundwater resources has led to undesirable effects, especially in the south, where aquaculture is concentrated. -
Hotspot Analysis of Taiwanese Breeding Birds to Determine Gaps In
Wu et al. Zoological Studies 2013, 52:29 http://www.zoologicalstudies.com/content/52/1/29 RESEARCH Open Access Hotspot analysis of Taiwanese breeding birds to determine gaps in the protected area network Tsai-Yu Wu1, Bruno A Walther2,3, Yi-Hsiu Chen1, Ruey-Shing Lin4 and Pei-Fen Lee1,5* Abstract Background: Although Taiwan is an important hotspot of avian endemism, efforts to use available distributional information for conservation analyses are so far incomplete. For the first time, we present a hotspot analysis of Taiwanese breeding birds with sufficient sampling coverage for distribution modeling. Furthermore, we improved previous modeling efforts by combining several of the most reliable modeling techniques to build an ensemble model for each species. These species maps were added together to generate hotspot maps using the following criteria: total species richness, endemic species richness, threatened species richness, and rare species richness. We then proceeded to use these hotspot maps to determine the 5% most species-rich grid cells (1) within the entire island of Taiwan and (2) within the entire island of Taiwan but outside of protected areas. Results: Almost all of the species richness and hotspot analyses revealed that mountainous regions of Taiwan hold most of Taiwan's avian biodiversity. The only substantial unprotected region which was consistently highlighted as an important avian hotspot is a large area of unprotected mountains in Taiwan's northeast (mountain regions around Nan-ao) which should become a high priority for future fieldwork and conservation efforts. In contrast, other unprotected areas of high conservation value were just spatial extensions of areas already protected in the central and southern mountains. -

Fifteen Years of Surface Deformation in Western Taiwan: Insight from SAR
Fifteen years of surface deformation in Western Taiwan: Insight from SAR interferometry Author links open overlay panel Mong-HanHuang ab RolandBürgmann ab Jyr-ChingHu c Show more https://doi.org/10.1016/j.tecto.2016.02.021 Get rights and content Highlights • InSAR reveals crustal deformation in western Taiwan during 1995-2001 and 2005-2008. • Seasonal deformation analysis shows the potential to distinguish tectonic and hydrologic deformation. • The long-term steady state deformation highlights the tectonic escape in southwestern Taiwan, whereas uplift along Western Foothills. • Significant land subsidence appears along coastal areas in western and southwestern Taiwan, and most of the land subsidence areas also experience higher (> 1 cm) seasonal variation. Abstract Geodetically measured surface displacements are produced by a combination of underlying deformation processes acting at different spatial and temporal scales. A complete history of surface measurements in an area can help discriminate contributions from tectonic, hydrologic, and anthropogenic processes. In this study, we use Synthetic Aperture Radar (SAR) images of the active mountain front and adjacent coastal plain of southwestern Taiwan to generate time series of surface deformation from 1995 to 2001 and from 2005 to 2008 based on the InSAR small baseline method. The InSAR measurements agree well with LOS motions estimated from continuous GPS measurements of 3D displacements between 2006 and 2008. A significant range increase in line of sight (LOS) is dominated by land subsidence in the coastal area of western and southwestern Taiwan. Subsidence rates vary with annual periods and are highly correlated with seasonal precipitation, which are likely associated with groundwater recharge and withdrawal. -

Rainfall forecasting derived from remote sensing data has been widely adopted for disaster prevention and early warning as a trend in recent years. By integrating high-resolution radar rain data, for example, the QPESUMS (quantitative precipitation estimation and segregation using multiple sensors) system provides a great opportunity to establish the extreme climate-based landslide susceptibility model, which would be helpful in the prevention of hillslope disasters under climate change. -
The Contribution to Tectonic Subsidence by Groundwater Abstraction in the Pingtung Area, Southwestern Taiwan As Determined by GPS Measurements
ARTICLE IN PRESS Quaternary International 147 (2006) 62–69 The contribution to tectonic subsidence by groundwater abstraction in the Pingtung area, southwestern Taiwan as determined by GPS measurements Jyr-Ching Hua,Ã, Hao-Tsu Chub, Chin-Shyong Houa,b, Tzu-Hua Laib, Rou-Fei Chenc, Pei-Fen Niena aDepartment of Geosciences, National Taiwan University, No. 1, Sec. 4, Roosevelt Road, Taipei 106, Taiwan, ROC bCentral Geological Survey, MOEA, P.O. Box 968, Taipei, Taiwan, ROC cObservatoire Oce´anologique de Villefranche-sur-Mer, Universite´ P. & M. Curie, France Available online 28 October 2005 Abstract The three sets of Global Positioning System (GPS) data collected from 1996 to 1999 are used to investigate the contribution to tectonic subsidence by groundwater abstraction in the Pingtung plain, southwestern Taiwan. The horizontal station velocities varied from 32 to 54 mm/yr for azimuths ranging from 247.21 to 272.61 with respect to the permanent station S01R located in the Penghu islands. In the central and western part of the study area, GPS stations move generally towards the west, whereas in the Kaohsiung–Pingtung coastal area, the displacement vectors demonstrate a clear counter-clockwise deviation towards the SW. The southern part of the offshore coastal area shows remarkable extension rates of 0.6–2.0 mstrain/yr along azimuth 015–0201. The significant southward increase of extensional strain rates is attributed to the lateral extrusion of blocks bounded by major discontinuities in the study area. For the vertical movement, the station velocities are from 13 to À25 mm/yr. Significant subsidence rates from 11 to 25 mm/yr have been observed. -

Johnson Received: 30 November 2016; Accepted: 25 January 2017; Published: 30 January 2017 Abstract: Recurrent flood events induced by typhoons are powerful agents to modify channel morphology in Taiwan’s rivers. Frequent channel migrations reflect highly sensitive valley floors and increase the risk to infrastructure and residents along rivers. Therefore, monitoring channel planforms is essential for analyzing channel stability as well as improving river management. This study analyzed annual channel changes along two sediment-rich rivers, the Zhuoshui River and the Gaoping River, from 2008 to 2015 based on satellite images of FORMOSAT-2. Channel areas were digitized from mid-catchment to river mouth (~90 km). Channel stability for reaches was assessed through analyzing the changes of river indices including braid index, active channel width, and channel activity.
