Extract: A study was made of the mineral (Na, K, Ca, Mg and Zn) contents in hair from 2 populations in Japan which have different salt intakes. Mineral determinations were conducted on untreated hair samples, and on hair samples washed with distilled water or 10% acetic acid solution. The sodium content of the hair of persons living in Akita (salt intake in excess of 20 g/day) was significantly greater than that of the hair of Papuans (salt intake estimated at about 200 mg/day). The potassium level in untreated Papuan hair was significantly greater than that of the hair of people in Akita; in washed hair, the opposite was found. The sodium/potassium ratio of hair from Akita was significantly greater than that of Papuan hair in all treatments. Except when acid washing wqs used, no differences were observed in calcium contents. Magnesium levels did not differ whatever treatment had been applied. The zinc content of Papuan hair was significantly less than that of Akita hair. (author)
