Abstract

The object of the present study is to measure the concentrations of toxic heavy metals in human eyes (cadimium and chromium) and major mineral iron ion. The heavy metals cadimium, chromium and iron were assayed using atomic absorption spectrometry. Metals determination in human eye is the most common application of biological monitoring for screening diagnosis and assessment of metals exposures and their risks. The statistical analysis of the metals (cadimium, chromium and iron) levels in human eyes showed that levels of the three metals in non-smoker were lower than metals contents of the smoker groups. Metals levels in human eyes of males were significantly lower than females. Statistically significant differences (p < 0.001) were observed between persons living in city centre and others who living in outskirt for concentrations of all three metals. Geographical influences are thought to be the main source of variability.
