|Abstract: ||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 of As, Cd, Co, Cr, Cu, Ni, Pb, and Zn were measured with an inductively
coupled plasma–mass spectrometer and mercury analysis was done using a mercury

analyzer. From the results, 30% of cassava samples collected, contained higher
concentrations of Pb when compared to Codex Alimentarius Commission standard values.
Bioconcentration factor indicated that Ni had higher capacity of absorption into food crops
from soil than the other heavy metals. For both children and adults, the target hazard quotient
(THQ) of Pb in cassava in communities such as Techiman, Wangarakrom, Samahu, and Tebe
(only children) were greater than 1, which is defined as an acceptable risk value. This
indicated that residents could be exposed to significant health risks associated with cassava
