Comparative Metal Distribution in Scalp Hair of Pakistani and Irish Referents and Hypertensive Patients

The aim of this study was to assess the heavy metals Cd, Ni, Pb, and Zn in scalp hair samples of 50 Irish and 78 Pakistani hypertensive patients of an urban population together with 50 Irish and 96 Pakistani non-hypertensive male subjects in the age group of 30-50 years. The results of this study showed that the mean values of cadmium, nickel, and lead were significantly higher in scalp hair samples of both Pakistani and Irish hypertensive patients than in referents; whereas, the concentration of zinc was lower in the scalp hair samples of hypertensive patients of both genders. The deficiency of Zn and the high exposure of trace and toxic metals may be the risk factors associated with hypertension.
