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

“…Following on from recent development of a pan-EU method for MeHg determination in sh samples, the methodology was assessed for use with real natural sh samples with a focus on intake by the Spanish population. 146 The MeHg was leached from the sample with HBr, extracted into toluene with back-extraction into L-cysteine. Preliminary studies were focused on the extraction efficiency, losses, contaminations, and prevention of species inter conversion.…”

Fast extraction methodologies for the determination of toxic arsenic in meat

“…The highest concentrations of As have been reported in fish, seafood, seaweed and cereals (JECFA, ). In marine animals, As is predominantly arsenobetaine which is rapidly excreted unchanged, whereas seaweed and rice present high proportions of inorganic As (Lynch et al ., ; Ruiz‐de‐Cenzano et al ., ). Therefore, progress in the assessment of total dietary intake of As requires to extend the aforementioned studies to other components of the diet such as meat products (European Union (EU), , Lynch et al ., ).…”

Robust ultrasound assisted extraction approach using dilute TMAH solutions for the speciation of mercury in fish and plant materials by cold vapour atomic absorption spectrometry (CVAAS)

“…8 These two are the common and predominant forms of mercury generally found in biological and environmental samples such as sh tissues and plant matrices. [9][10][11][12][13] Because of the accumulative properties and adverse toxic effects of mercury species even at ultra-trace levels, its accurate determination in sh and plant samples is very important for environmental protection and food safety.…”
