Copper mine waste deposited in Arboricultural Research Institute may cause some environmental pollution, but this has not yet been clarified. Stream water, soil, and plant samples were collected on and around mine waste deposits to investigate their copper content. Soil samples contained quite high concentrations of copper, as much as 1,050 mg/ kg, showing that soils have been contaminated by copper. Copper was rarely detected in stream water, which suggested that copper pollution in stream water is not serious at present. Vegetation on the deposit site was very sparse, but copper concentrations of most Plant leaf samples were within normal levels.
