Determination of mercury in hair: Comparison between gold amalgamation-atomic absorption spectrometry and mass spectrometry

Simple and rapid method for the determination of mercury in human hair by cold vapour generation atomic fluorescence spectrometry

“…Because of the lack of data on Hg concentrations in African hair, the results of the analysis of an Eritrean population in the present study (Table 3) were compared with those of other studies conducted worldwide [27,34,36,62,78]. The average Hg level (0.21 ± 0.24 mg kg −1 ) was found comparable only with that of a Swedish population (0.26 ± 0.14 mg kg −1 ) obtained by Rodushkin and Axelsson [78] and lower than the mean levels reported in other studies: half that of Poland (0.50 ± 0.39 mg kg −1 ) measured by Chojnacka et al [62], one-third of that from Italy (0.66 ± 0.59 mg kg −1 ) measured by Domanico et al [34], one-tenth of that from Iran for non-fishing families (2.27 ± 2.10 mg kg −1 ) obtained by Okati and Esmaili-sari [27], and one-twenty-fifth that from Spain (5.38 mg kg −1 ) measured by Raposo et al [36]. These differences can be attributed to environmental and occupational exposures, hair colour, ethnic and geographical origin, and seafood consumption [26,51,87,89,90].…”

“…For Hg determination in biological samples, the most common instrumental techniques are atomic absorption spectroscopy (AAS) [27][28][29][30][31][32] and inductively coupled plasma-mass or optical emission spectrometry (ICP-MS or ICP-OES, respectively) [15,[33][34][35][36][37], typically coupled to cold vapour generation (CV) for matrix separation. However, memory effects can occur during the determination of total Hg by ICP-MS [38].…”

Determination of Mercury Content in Surface Waters Using an Environmentally Non-Toxic Terminating Electrolyte

“…Other methods are often used to analyse mercury from aqueous solutions, including, inter alia, the extraction and colorimetric method, flameless atomic absorption spectrophotometry combined with the cold vapour method (CV-AAS) and the indirect dithizone method with copper carbamate. The methods of mercury determination have been compared a number of times (Giacomino et al 2017 ; Kwaansa-Ansah et al 2016 ; Xia et al 2010 ; Domanico et al 2017 ). In this study, however, the analysis was limited to isotachophoresis following the previously developed methodology (Kluska et al 2014 ).…”

Determination of Hg in Hair of Miners in Abu Hammed City (Indiscriminate Mining Area) Using Direct Mercury Analyzer, Sudan

“…Considering that hair grows ca. 1 cm per month and that the half-life averages of MeHg in hair is about 65 days (range of about 35-100 days), it would be possible to quantify the Hg load due to a long period of exposure (2) .…”

“…The presence of Hg in hair is generally evaluated by different techniques such as the cold vapor atomic absorption spectroscopy (CV-AAS), inductively coupled plasma atomic emission spectrometry (ICP-AES) and Direct Mercury Analyzer (DMA). All these techniques are sensitive, precise and supply reliable and reproducible data, but, on the other hand, they are very time-consuming techniques due to the pretreatment of samples (2) .…”
