“…Although fish consumption is a major source mercury exposure, in this study fish consumption had no effect on the level of mercury in dentists or control group hair and this finding accords with Harakeh [2]. A significant correlation between hair mercury level and fish consumption have been reported in our previous study in other nation [7]. The absence of correlation between hair mercury level and fish consumption may be due to the very low frequency of fish consumption in the city.…”

The mean level of total mercury in hair samples of dentists (occupational exposed population) and non occupational exposed population (control group) in Benghazi city were carried out. The level of total mercury (mean ± standard deviation) in hair samples of dentist was 5.99± 2.64 mg/kg in the range of 3.44-776 mg/kg. For control group, the mean level of total mercury (mean ± standard deviation) was 0.81 mg/kg in range of LOD-3.6 mg/kg. In comparison, our results indicated that, the level of mercury in dentist is significantly higher than those of control group. The effect of age, gender and fish consumption were also carried out.

“…There are several methods available for speciation analysis of mercury in human hair, including neutron-activation analysis, 14 high energy-resolution X-ray absorption near-edge structure (HR-XANES) spectroscopy, 15 and hyphenated techniques. Hyphenated techniques are usually a chromatographic separation technique (high-performance liquid chromatography (HPLC), gas chromatography (GC), capillary electrophoresis (CE), etc.)…”

Speciation analysis of mercury in hair facilitates accurate evaluation of mercury exposure to humans and insights into the intertransformation of different mercury species in the human body. However, conventional hyphenated techniques used for mercury speciation analysis usually require expensive instruments and a complex interface. In this work, a compact and miniaturized point discharge (PD) atomic emission spectrometer was utilized as a detector of gas chromatography for the speciation analysis of mercury. Mercury species extracted from hair were derivatized to their volatile species with NaBEt and subsequently preconcentrated by headspace solid-phase microextraction (HS-SPME) prior to their speciation analysis. Under the optimized conditions, limits of detection of 0.35 μg kg (0.035 ng) and 1.0 μg kg (0.10 ng) were obtained for IHg and MeHg, respectively, with a relative standard deviation (RSD) of better than 3.5%. Because of the compact and miniature conformation, high excitation capability, low power consumption of PD-OES, and efficient preconcentration of mercury species by HS-SPME, the proposed system not only overcomes the shortcomings associated with the conventional hyphenated techniques but also provides several unique advantages, including significant simplification of experimental setup, reduction of dead volume, and improvement of sensitivity. The accuracy of this system was validated by speciation analysis of mercury in a Certified Reference Material (GBW09101b, human hair) and 10 human hair samples collected from different people in the population.

“…Table 5 summarizes Hg concentration in residents of Malaysia. Sarmani and Alakili (40) reported that high levels of Hg concentration in Chinese and Indian hair samples may be due to differences in lifestyles, namely, more marine food consumption and use of traditional medicinal products that contain Hg. Hajeb et al (37) showed that hair Hg concentration in Malaysian communities is higher than that found in the research done by Sarmani and Alakili (40); such high concentration can be attributed to different geographical and environmental conditions.…”
