The quantities of cadmium, lead and mercury introduced into beans ground on domestic Nigerian grinding stones have been determined using colorimetric methods. The highest additions of cadmium, lead and mercury were 0.14, 0.72 and 0.17 mg kg −1 , respectively. The corresponding lowest values were 0.01, 0.05 and 0.01 mg kg −1 , respectively. These amounts introduced by the grinding stones are greater than the tolerable daily intakes recommended by the World Health Organisation.
