Adsorption of HgCl2 and CH3HgCl in aqueous solutions by the hair was measured at 20°C and 30 °C. The concentration of adsorbed Hg was higher at 30°C than 20°C; both isotherms adapted well to Freundrich equation.An increased mercury concentration on the hair was clear even in extremely dilute mercury solutions.Desorption of HgCl2 adsorbed by the hair was poor when hair was washed with HCl solutions. But the CH3HgCl on the hair was eluted very well with 1N HCl solution. A washing with 1mM of L-cysteine did not elute the mercury on the hair much.Thus, desorption of only the outer-adsorbed mercury on head hair is considered impossible. Measurement of methylmercury is recomended as a sign of internal organic mercury absorption.
