Case Reports: Arsenic pollution in Thailand, Bangladesh and Hungary

The purpose of this review is to share information on how arsenic contamination arises and what options are available to mitigate it when it occurs. We describe how contamination arose in three countries, two Asian, and one European, and the approaches employed to resolve it. In the three selected countries, the presence of arsenic is both long term and of geological origin, yet the affected regions have distinct and contrasting concerns, both in the scale of the contamination of the abiotic environment and in the extent of human health impacts arising from arsenic exposure. Therefore, we hope that knowledge of the range of problems encountered in the three countries, and their potential solutions, will contain common themes that, at least partly, facilitate stakeholder endeavours to address arsenic contamination in other affected regions
