A broad-applicability method for mercury speciation in various seafoods using microwave-assisted extraction and ion chromatography-inductively coupled plasma mass spectrometry

Abstract

Almost all of marine organisms contained both inorganic and organic mercury, and thus it is extremely important to determine mercury species in seafood to objectively and scientifically assess mercury’s health...

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…They concluded that the arsenosugars are not a product of As detoxification, but a by-product of normal biological activity. For the speciation of Hg in seafood (seaweeds, fish and shellfish) Li et al 100 developed a MAE method in which 0.10 g of dried sample was mixed with 7.0 mL of 100 mmol L −1 HNO 3 + 6.0 mmol L −1 cysteine solution and allowed to stand for 6 h at room temperature. Then, the closed vessel was microwave heated to 120 °C within 10 min and held for 30 min at 120 °C.…”

Mercury determination in various environmental, food and material complex matrices using unified operating conditions for a cold vapor generation high-resolution continuum source quartz tube atomic absorption spectrometry method

“…3–18 Hyphenated techniques such as high-performance liquid chromatography in conjunction with post-column cold vapor (CV) derivatization and detection by AFS (HPLC-CV-AFS) or inductively coupled plasma mass spectrometry (HPLC-ICP-MS), gas chromatography coupled to AFS (GC-AFS) or ICP-MS (GC-ICP-MS) have been developed to provide high sensitivity, accuracy and lack of spectral and non-spectral interference for Hg speciation in food, biological and environmental samples. 19–25…”
