Series: Arsenic in the environment
In the 1950s, the residents of the southwestern coastal areas of Taiwan suffered greatly from Blackfoot disease (BFD) due to the consumption of arsenic-contaminated groundwater. Groundwater with high levels of arsenic in southwestern and northeastern Taiwan received much attention. After arsenic-safe tap water was utilized for drinking instead of groundwater in the 1970s, BFD cases decreased greatly. After 1990, no new BFD cases were reported, and as a consequence, BFD problems disregarded. However, arsenic is still present in the groundwater.
This book will improve the knowledge and understanding of the occurrence and genesis of arsenic-rich groundwaters in Taiwan. It deals with constraints on the mobility of arsenic in groundwater, its uptake from soil and water by plants, arsenic-propagation through the food chain, human health impacts, and arsenic-removal technologies. Taiwan case experiences are described in this book and can be applied worldwide.
This book is a state-of-the-art overview of research on arsenic in Taiwan and is designed to:

Jiin-Shuh Jean (1952, Taiwan) finished his PhD degree in Hydrogeology, specializing in groundwater modeling, from Purdue University, West Lafayette, Indiana, USA. He is a full professor of Hydrogeology at the Department of Earth Sciences, National Cheng Kung University (NCKU), Tainan City, Taiwan. His current research interest is in arsenic mobilization and removal.
He is now an associate editor of the Journal of Hydrology, Elsevier and a local chief organizer of the 3rd International Congress on Arsenic in the Environment, which will be held on 17-21 May 2010 at NCKU, Taiwan.
Jochen Bundschuh (1960, Germany) has been working in international academic and technical co-operation programs in different fields of water and renewable energy resources for more than 17 years for the German government. He was a long-term professor for the DAAD (German Academic Exchange Service) in Argentina and an expert of the German Agency of Technical Cooperation (GTZ) (1993-1998). From 2001 to 2008 he worked within the Integrated Expert Program of CIM (GTZ/BA) as an advisor to Costa Rica at the Instituto Costarricense de Electricidad (ICE).
Since June 2009 he has been teaching as a professor in the field of renewable energies, in particular geothermics, at the University of Applied Sciences in Karlsruhe (Germany) and is also a researcher at the Institute of Applied Research at the same university, where he works in geothermics and the groundwater arsenic issue.
