| Popis: | In April 2000, a UNIDO study was carried out in Dumasi, Ghana, the purpose of which was to determine the environmental impacts of mercury prior to the introduction of (mercury) retorts. The sampling program was intended to identify mercury transfers to rivers, soil systems and groundwater. Results show a diffuse contamination of all environmental media in the village. Although there is no evidence of groundwater contamination, sediments are significantly contaminated, and most fish fillets have mercury contents exceeding the United States Food and Drug Agency (US-FDA) action level, and are therefore unfit for human consumption. Mercury losses mainly occur during amalgamation, and have resulted in widespread pollution of soils and sediments throughout the village. Transparent retorts have been introduced and environmental training is ongoing but these efforts have only partially addressed the mercury problem in Dumasi. 2002 Elsevier Science Ltd.
