The concentrations of lead, cadmium, cobalt, and manganese in salts from Ghana were within safe limits, with estimated daily intakes below tolerable levels. Health risk assessment showed that consumption of these salts posed no potential health risks to humans and are considered safe.
The concentrations of lead (Pb), cadmium (Cd), cobalt (Co), and manganese (Mn) in salts from four salt winning communities (Ada, Nyanyano, Saltpond, and Elmina) and two commonly consumed refined salts brands (coded A and B) in Ghana were measured using atomic absorption spectrometry. The concentrations of Pb, Cd, Co, and Mn in the samples ranged 0.24-0.68, 0.08-0.27, 1.67-1.72, and <0.08-0.27 mu g/g, respectively. The estimated daily intakes (EDIs) of the metals were below the tolerable daily limits. In addition, the health risk assessment indicated that the consumption of these salts poses no potential health risk and are therefore safe for humans.
