Abstract
In this study, we investigated the extent of contamination of Hg in selected mine-impacted
Ghanaian watersheds. Our results are suggestive of a major environmental problem with Hg in Ghana,
with total-Hg concentrations ranging from 17 to 2000ng L
-1 in surface water samples, and in hundreds
of ppm for both soils and sediments.
