Since the presence of arsenic in iron ore lumps is related to the presence of iron it is assumed that the highest concentrations of arsenic is in the browncoloured deposit that stays behind on the hand after contact with the lumps This deposit attaches well to the hand surface certainly in the case of wet hands like in a beach setting
