"...this book, although it is a proceedings volume from a workshop, gives a very useful update of the As problems, especially in Bangladesh and West Bengal, but also in other regions around the globe. Several new interesting case studies are presented and updated and also biogeochemical matters are discussed. Remediation is also discussed. The list of contributors is impressive (more than 100 contributors) which also shows the worldwide interest in this topic.The book is recommended for all those working on As and fulfills a real need on the status of As research now."Olle SelinusGeological Survey of SwedenIn: Applied Geochemistry 21 (2006) 724–725
