Ghana is a major producer of gold in the world and ranks first in West- Africa in terms of production. It has however been noted that, the activities of gold mining are accompanied by serious environmental consequences as a result of the chemicals used in extraction of the ore and the methods employed in mining. Chemical contamination and water pollution have been key concerns of the effects of gold mining in Ghana. This study reviewed best available techniques in the clean-up of mining contaminants worldwide and the application of such methods to environmental problems caused by gold mining...

Quelea control operations in Africa normally have severe effects on non-target bird species and the environment. Aerial applications of pesticides create a high off-target drift potential, which results in unreliable effectiveness and could cause contamination over large areas. Fenthion pesticide (Queletox) was aerially applied in 2004 in Sebalola, Botswana. As part of an Environmental Impact Assessment of this operation, pre-spray soil samples and post-spray soil samples were collected, air-dried, bagged, transported to the UK and kept deep frozen. Initial analysis of the samples...
