“…Lead is also one of the most-used nonferrous metals in the manufacture of metal products, chemical, batteries, and various other items [28]. Human hair usually contains less than 5 mg/kg of lead, and high exposure is indicated by lead concentrations of above 25 mg/kg [28]. Therefore, from this statement, it can be concluded that the exposed groups studied here had not suffered from high occupational lead exposure.…”

Assessment of Heavy Metals on Occupationally Exposed Workers from Hair Analysis

The use of human hair as a tool in assessing changes and abnormalities in human bodies has been increasing for last decades since it may reflect the health status or environmental condition of habitation or working place of individuals as well as population groups. Compared to other body tissue or fluids, hair provides an ease of elemental analysis especially in reflecting the long-term exposure. This research was conducted to determine the elemental content especially heavy metals, since they are bioaccumulated in human body organs and impact human health, in hair of workshop workers and traffic services officers as exposed groups and its comparison with control group and references data for assessing of occupational exposure. Thirty-five automotive workshop workers and 32 traffic services officers' hair specimens were collected in Bandung, while hair specimens of the control group were collected from 43 healthy individuals. The elemental concentrations in hair specimen were analyzed using neutron activation analysis (NAA) for mercury and chromium, and atomic absorption spectrometry (AAS) for lead and arsenic. The accuracy of the method was evaluated using GBW 07601 human hair certified reference material (CRM) and it was found to give good results in accordance with the certificate values. It was found that chromium, lead, and arsenic hair concentration in exposed groups (0.88, 10.7, and 0.051 mg/kg, respectively) were higher than in control group (0.27, 4.52, and 0.045 mg/kg, respectively), while mercury hair concentration of traffic services officers were higher than control group but mercury hair concentration of automotive workshop workers were lower than in control group (1.41 mg/kg). The t-test statistical results shown that mercury concentrations in one exposed group did not differ significantly from the control, but other exposed groups showed otherwise. The level of mercury in hair is strongly attributed not only to environmental exposure, but also to lifestyle and dietary habits, while t-test statistical results of chromium and lead differ significantly with p value < 0.05. These results indicate that heavy metal hair concentrations were well quantified to show the abnormalities of elemental concentration in human hair for evaluating the occupational exposure.

“…Similar multielemental hair analyses among the population of students of other countries were reported. González-Muńoz et al (2008) found that female students of Alcala (Spain) generally have higher levels of Cu, Ni, Cr and Pb than male students (Pena-Fernandez et al, 2014). Khalique et al (2005) reported that hair of Pakistan female students was richer in elements such as: Cu, Co and Ni, while the content of Cr was lower than in the hair of males.…”

“…Human serum, blood, urine, hair, and saliva are typical samples of human biological materials analyzed in the context of element composition wherein the latter three types of sample, as non‐invasive matrices, are used in human biomonitoring to study the influence of the environment on the human body. In such studies, the reference values both for macro, trace, and toxic elements are needed and are systematically determined for different human samples …”

Determination of lead at physiological level in human biological materials using the total reflection X‐ray fluorescence analysis

et al. 2016

Total reflection X-ray fluorescence (TXRF) analysis was applied in determination of low concentration of lead in samples of human biological materials. The determination of lead in human serum and hair samples is presented as an example. In serum samples, lead concentration was in the range from 0.013 to 0.051 g/g (median 0.024 g/g). The reference ranges of lead content in hair are from 1.41 to 4.08 g/g for men and from 1.18 to 3.29 g/g for women groups, respectively. Because of Pb concentration range close to the detection limit of the TXRF method, the measurement needed evaluation of the best analytical conditions. This paper presents the results of this evaluation, namely internal standard selection, measurement conditions, and quantitative calibration of the spectrometer. Finally, as a result of evaluation, the detection limit was found on the level 0.001 g/g (water solution) and about 0.005 g/g for human hair samples and 0.007 g/g for serum samples. The obtained values reach nearly the physiological lead level. The presented results are of practical importance for lead concentration studies in human biological materials using the TXRF method.
