Mining-related contamination of land and water by potentially toxic elements is a recognized problem in many parts of the world. Arsenic is one such element that is causing particular problems with regard to human and environmental health in some tin-mining areas in Thailand.
This project is designed to establish long-term field experiments to study the application of locally-available diatomite to As-contaminated land and wastes in a tropical context in areas of recognized arsenism and As-impacts on the environment. The first stage of this project is to identify As-contaminated sites in Thailand that are suitable for the establishment of long-term field plots involving the application of locally-available diatomite to As-contaminated land. This report describes work involved in identifying suitable sites for the establishment of field trials.
