Trace element distribution in human eye

A hundred samples of four types of eye tissues and hair from a set of 10 donors from the city of Prague were analyzed using INAA. The hair samples of the set of donors were taken as the indicator of the environmental conditions. Within the framework of the set of results obtained for 30 chosen elements, the differences between various types of tissues and sex were tested. The lowest trace element deposition was found for the lens tissue. The iris differs predominantly by the higher contents, particularly of metal elements. Slightly higher contents of practically all trace elements under study were found in all eye tissues taken from male donors.
