This study was carried out to assess the extent of heavy metals and metalloid accumulation from agricultural soils to foodstuffs (viz, M. esculenta (cassava) and Musa paradisiaca (plantain)) around thirteen neighboring communities within Tarkwa, Ghana; and to estimate the human health risk associated with consumption of these foodstuffs. Concentrations …
The growth of highly populated mega-cities has also exacerbated problems of metal recycling and reclamation and has given rise to the concept of 'urban mining' – the recovery of important elements from urban waste (Cossu et al., 2012; Lyons and Harmon, 2012). In addition, the increasing need for energy production from renewable resources ...
