“…Following water samples, the most frequently analyzed material for mercury was seafood samples, such as fish, shrimp, and seaweed. A few studies reported the determination of mercury in various environmental samples, such as petroleum hydrocarbons [ 88 ], human hair [ 89 , 90 ], phosphate fertilizers [ 53 ], glycerin [ 91 ], sediments [ 55 , 92 , 93 ], cosmetics [ 94 ], living cells [ 66 , 95 ], and tobacco [ 67 ]. However, a few methods [ 74 , 81 , 87 , 96 – 101 ] did not report their applicability to natural samples.…”

This paper reviews the current research on the speciation and determination of mercury by various analytical techniques, including the atomic absorption spectrometry (AAS), voltammetry, inductively coupled plasma optical emission spectrometry (ICP-OES), ICP-mass spectrometry (MS), atomic fluorescence spectrometry (AFS), spectrophotometry, spectrofluorometry, and high performance liquid chromatography (HPLC). Approximately 96 research papers on the speciation and determination of mercury by various analytical instruments published in international journals since 2015 were reviewed. All analytical parameters, including the limits of detection, linearity range, quality assurance and control, applicability, and interfering ions, evaluated in the reviewed articles were tabulated. In this review, we found a lack of information in speciation studies of mercury in recent years. Another important conclusion from this review was that there were few studies regarding the concentration of mercury in the atmosphere.

“…The conventional analytical methods for the detection of Hg 2+ usually rely on the use of advanced instruments based on spectrometric and chromatographic techniques, such as atomic absorption spectrometry (AAS) [ 1 , 5 ], inductively coupled plasma mass spectrometry (ICPMS) [ 6 ], graphite furnace atomic absorption spectrometry (GFAAS) [ 2 ], inductively coupled plasma atomic emission spectrometry (ICP-AES) [ 7 ] and liquid chromatography inductively coupled plasma mass spectrometry (LC-ICP-MS) [ 8 ]. While such approaches have been proven to be highly accurate and sensitive, the complex, expensive and time-consuming procedures associated with these methods call for a simpler alternative for daily analysis and on-site detection in a large number of samples in the field.…”

In the present study, indium tin oxide (ITO) was used as a transparent working electrode for the development of an electrochemical sensor for the detection of mercury (II) ions (Hg2+). The electrode was modified by direct electrodeposition of polyaniline (PANI), multiwalled carbon nanotubes (MWCNTs) and gold nanoparticles (AuNPs) followed by optimization of the analyte and operating conditions, aiming to improve the selectivity, sensitivity and reliability of the electrode for mercury detection. Successful immobilization of the PANI and nanomaterials (MWCNTs and AuNPs) on the ITO electrode was confirmed by Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX) and Fourier Transform Infrared Spectroscopy (FTIR) analyses. The optimum conditions for mercury detection using the modified ITO electrode were pH 7.0 of Tris-HCl buffer (50 mM) in the presence of 1 mM methylene blue (MB) as a redox indicator, a scan rate of 0.10 V·s−1 and a 70 s interaction time. The electrochemical behavior of the modified electrode under the optimized conditions indicated a high reproducibility and high sensitivity of mercury detection. It is therefore suggested that the PANI/MWCNT/AuNP-modified ITO electrode could be a promising material for the development of on-site mercury detection tools for applications in fields such as diagnostics, the environment, safety and security controls or other industries.

“…Although the single use of a cosmetic containing a toxic element is not associated with obvious side effects, the prolonged human systematic exposure can rarely be completely excluded from skin allergy or cancer even at normal usage [7,8]. For these reasons, the health risk related to the usage of cosmetic has currently become an emerging public health problem [9], and the safety assessment of cosmetic products on inorganic elements has drawn great attention during the last decade [10,11].…”

This paper presented the arsenic determination in four different brands of cosmetic face-creams to provide valuable information on the safety levels for consumers. The cosmetic samples were decomposed by acidic digestion method and then taken for arsenic quantification using inductively coupled atomic emission spectrometry (ICP-AES). The digestion efficiency of acid mixtures including concentrated HNO 3 , HNO 3-HClO 4 , HNO 3-H 2 O 2 and aqua regia was discussed in terms of digestion loss and time consumption. The ICP-AES analyzing results, with determination recoveries of 95.4% ~ 105.2% and relative standard deviations less than 3.0% (n = 5), revealed arsenic contents in the face-creams are in the ranges of 0.68 ~ 3.28 mg•kg −1. Obviously, the arsenic contents in some of the studied brands exceed the maximum recommended value of 2.0 mg•kg −1 set by China. These results lead to the conclusion that constant control of arsenic content in cosmetics should be seriously considered. The successful arsenic determination in cosmetic face-creams by digestion pattern of concentrated HNO 3 , with simplicity, higher efficiency, less reagent consumption and less analytical time well demonstrates the good analytical capability of this method, promising a great possibility for large batches of cosmetic toxic metal monitoring.

Mercury(II) determination in commercial cosmetics and local Thai traditional medicines by flow injection spectrophotometry

Abstract: Enhancement of sensitivity and rapidity for Hg(II) assay by FIA could be achieved by adding SDS in ascorbic acid. The method would be useful for routine analysis of Hg(II) in real samples.
