Introduction: Identification and analysis of keratin-based tissues has always been used as an indicator of different element absorption into the body. In this study, the hair and nail compositions of people living in the urban community of Hamadan to determine the amount, difference and relationship of the measured elements were investigated.
Methods: Samples were collected from the city of Hamadan in 2019. By considering the sex and the age, the people were divided into three group of normal, athlete and addicted based on physical activities. The quantitative elemental concentration in hair and nail samples was determined by PIXE technique. The statistical data were performed by Origin Lab pro software.
Results: Among the identified elements in the hair samples of females, a significant difference was determined between the element P with the elements of Cr and Ni (P<0.001) and a moderate difference with the element Co (P<0.01). No significant differences were found between hair elements in the male gender. Also, the quantitative p-value of element P between groups the normal people with addicts as well as the p-value of element Ca between groups of athletes with addicts was equal to p 0.01. In female nail samples, there was a significant difference between the element P and the elements of Ca, Cr and Al. The correlation coefficient of 0.33 was found among the common elements in the hair and nail samples.
Conclusion: The existence of a significant difference between the Calcium and its ratio in the hair and nail sample by considering the variables of gender and age can be used as a biomarker in forensic medicine.
