Hair
and nail samples were collected during a period of October
to December 2012
from 63 healthy subjects who have been living in Zonguldak for at least ten consecutive years. The subjects
aged over 30 years and having no serious health problems were participated in
the study. The methodology involved the collection, ultrasonic cleaning and
microwave digestion of samples. The measurements of trace metals (As, Cu, Zn,
Se, Cd, Pb, Cr, Fe and Ni) in samples were performed with inductively coupled
plasma-mass spectrometry. The predominant metals
determined in the both hair and nail samples were the essential metals with the
decreasing concentrations in the order of Zn>Fe>Cu. Other metals
determined in the hair samples followed the concentration order of Pb>Se>Ni>Cr>As>Cd, whereas in the nail samples, the order was
Se>Ni>Cr>Pb>As>Cd. Subgroups were formed according to location
and gender. Hair Se and Fe concentrations were significantly
higher in urban residents. With
regard to nail samples, the rural residents exhibited more elevated Fe levels
significantly. Gender
had a significant influence on the concentration of Zn and Cu in hair samples with females presenting higher values. However,
the effect of gender on the trace metal concentrations in nail samples was
negligible. The metal concentrations obtained for Zonguldak
were within or below the values reported
worldwide.
