“…The derivatization was preferably applied for the conversion of low volatility mercury and organomercury ions to volative organomercury molecules which have higher volatility. Various derivatization reagents like sodium tetraalkylborate (NaBR 4 ) can be employed for aqueous phase derivatization while Grignard reagents were mainly used in the past for organic phase derivatization [10,16]. The most useful tetraalkylborate reagent is the tetraethylborate (NaBEt 4 ) [3, 6 -9, 11].…”

A rapid and sensitive method has been developed for the simultaneous determination of monomethylmercury (MMHg) and inorganic mercury (iHg) in human body fluids. The procedure is based on in situ derivatization of MMHg and iHg with sodium tetraethylborate (NaBEt(4)) directly in aqueous solutions followed by headspace solid phase microextraction (HS-SPME). The extracted species from spiked human urine, saliva, and serum are separated by capillary gas chromatography and detected by quadrupole MS (GC-MS). The optimization of the HS-SPME conditions like temperature, sample volume, extraction duration, and amount of alkylation agent, was performed in urinary solutions and aqueous solutions similarly buffered. The gas chromatographic conditions like injection temperature, helium flow rate, temperature program, and pressure conditions were also optimized. The recovery was ranged between 85 and 96% for MMHg and 88 and 98% for iHg. The LODs achieved were 10 and 15 ng/L for iHg and MMHg in urine, respectively, 54 and 60 ng/L for iHg and MMHg in saliva, respectively, and 61 and 81 ng/L for iHg and MMHg in serum, respectively. The RSD was ranged between 6.2 and 9.2% for MMHg and 5.0 and 8.2% for iHg.

In this study, total mercury and methyl mercury in whole blood of Korean was analyzed so as to investigate the correlation between total mercury (T-Hg) and methyl mercury (Me-Hg). 4000 whole blood samples were divided in four groups, according to T-Hg concentration in percentile: group I (p25-p50), group II (p50-p75), group III (p75-p95) and group IV (p95-p100). 100 samples were randomly selected from the each group, and Me-Hg concentration was measured. T-Hg concentration in whole blood was analyzed using a Direct Mercury Analyzer-80 and obtained limit of detection (LOD) was 0.2 µgL −1. Me-Hg concentration was analyzed with ethylate derivatization using headspace-gas chromatography-mass spectrometry, and obtained LOD of methyl mercury was 0.5 µgL , respectively, and 71.91% of T-Hg was presented as Me-Hg.
