Geochemical atlas of Hong Kong

This atlas provides the most up-to-date account of the concentration and distribution of selected chemical elements in the surface environment. It contains baseline data from approximately 2200 stream sediment sample sites across the Hong Kong SAR. This information is stored on the Planning Division's Geological Modelling System.

Potential applications of the geochemical data include land use planning, environmental monitoring and pollution control, waste management, the recognition of the effects of trace element deficiency or toxicity on crops, and various aspects of human and animal health.
