Zimbabwe: Mozambique and Zimbabwe Discuss River Pollution

The Revue and Pungoe rivers are being heavily polluted by mercury and other toxic substances used by the gold miners. There are two major dams on the Revue, at Chicamba and Mavuzi, and pollution by heavy metals raises questions about their future.
The rivers are also vital to drinking water supplies for Chimoio, Beira and other major urban centres in Manica and Sofala provinces. Mercury pollution is a serious threat to human health. The pollution can also have damaging effects on irrigation, agriculture and fish farming
