“…Both pairs showed no significant differences at p = 0.05. The negative correlation between Zn and Cu was opposite to the results reported in Wee and Ebihara (2017), whereby their research has indicated that Zn and Cu had positive correlations. Unlike the explanations made in this literature, this study showed that Zn and Cu were not in good balance among the research participants.…”

“…Each batch of fingernail sample was washed using the methods reported in Wee and Ebihara (2017). Upon transferring samples into a beaker, acetone was added just enough to cover the nails and left aside for 20 minutes.…”

“…Based on literature values of Cu from other countries, most of the concentrations found present in fingernail samples were less than 10 µg/g. For example, Nowak and Chmielnicka (2000) reported that Polish volunteers had mean Cu concentrations of 7.0 µg/g in their fingernails, Canada volunteers gave mean values of 9.2 µg/g (Li et al, 2012), Saudi Arabia adults had values of 9.01 ± 1.03 µg/g (Momen, Khalid, Elsheikh & Ali, 2015) and the participants in Japan gave results of 5.18 ± 1.72 µg/g (Wee & Ebihara, 2017). When the results of this work were compared with the study done in Malaysia previously, Cu levels in nails of volunteers in Kuching and Kota Samarahan were very high.…”

Trace elements play a significant role in giving nutritional benefits to the body because they act as essential cofactors for all physiological processes. However, there are some trace elements which may bring more harm than good when entering the human body. Due to its ability to incorporate trace elements in an amount that is proportional to an individual’s dietary intake and environmental exposure, human fingernails are suitable biomarkers in assessing the health status of an individual as they reflect on the trace element concentration present in the body. This study has analysed fingernail samples of 23 adult females residing in Kuching and Kota Samarahan, Sarawak, Malaysia for four elements, namely Cd, Cu, Pb and Zn. By using flame atomic absorption spectroscopy (FAAS), the mean elemental concentrations found in fingernail samples of research participants were 171.8 ± 33.8 μg/g for Zn, 27.8 ± 14.8 μg/g for Cu and 2.64 ± 0.94 μg/g for Pb. Cd concentrations were not able to be detected as they were below the detection limits. A standard reference material, NIST 1568b Rice Flour was used to verify the methods used in elemental analysis using FAAS. Independent t-test which was used to compare the means of Zn and Cu between vegetarians and non-vegetarians showed no significant differences for both elements. Moreover, correlation analysis showed negative correlations between Cu/Zn pair and Pb/Zn pair, whereas significant positive correlation was obtained for Cu/Pb pair. The overall data from this study showed good agreements with data obtained from studies in other countries. Therefore, the current data in this study represents the latest background elemental concentrations in fingernails of the residents in Kuching and Kota Samarahan, Sarawak.Keywords: Adult females, fingernails, flame atomic absorption spectroscopy (FAAS), trace elements

the studies of trace element composition in the human nail is called ashuman bio monitoring. The composition of the chemicals and traceelements and concentration of the chemicals and trace elements in thehuman body fluids and human body tissues are observed .Theconcentration of trace elements for a healthy human being is stable for aparticular period of time in their nail and also the composition of chemicalelements in the nail differs to each individual. So the humans nails can beused as the bio marker for monitoring or quantifying the composition ofchemicals (major and trace elements) in the human body. So traceelement's composition and concentrations in the nail can be considered forBio-metrics authentication in future. Because the chemical composition ofnail and chemical concentration in the human nail differ from one peopleto another people and so this can be used to identify the individual infuture.Index terms–elements, trace elements, human bio monitoring, humanbody, nail
