Assessment of museum staff exposure to arsenic while handling contaminated exhibits by urinalysis of arsenic species
Preservation of museum objects with inorganic arsenic compounds and contamination of the surroundings has previously been documented. The present study addresses the exposure of museum staff by measuring arsenicals in urine. After 1 week without exposure, urinary samples were taken before and after handling of preserved skins and analysed by HPLC-ICP-MS for inorganic arsenic, arsenic metabolite...
متن کاملDevelopment of an analytical method for the determination of arsenic in urine by gas chromatography-mass spectrometry for biological monitoring of exposure to inorganic arsenic.
OBJECTIVES The purpose of this study was to develop an analytical method for the simultaneous determination of inorganic arsenic [As(III) and As(V)] and monomethylarsonic acid (MMA) in urine by gas chromatography-mass spectrometry (GC-MS) for the biological monitoring of exposure to inorganic arsenic. METHODS Arsenic compounds (after reduction of arsenic to the trivalent state) were derivatiz...
متن کاملAnalytical methods for arsenic speciation analysis
Arsenic exists in the form of various chemical species differing in their physicochemical behaviour, toxicity, bioavailability and biotransformation. The determination of arsenic species is an important issue for environmental, clinical and food chemistry. However, differentiation of these species is a quite complex analytical task. Numerous speciation procedures have been studied that include ...
متن کاملBiological monitoring of occupational exposure to inorganic arsenic.
OBJECTIVES This study was undertaken to assess reliable biological indicators for monitoring the occupational exposure to inorganic arsenic (iAs), taking into account the possible confounding role of arsenicals present in food and of the element present in drinking water. METHODS 51 Glass workers exposed to As trioxide were monitored by measuring dust in the breathing zone, with personal air ...
متن کاملHuman exposure asseessment to different arsenic species in tea.
BACKGROUND Inorganic forms of arsenic are much more highly toxic to humans than organic species. Their effects include being carcinogenic, genotoxic and neurotoxic, where in the latter case, above all, they affect nervous system development in the foetus, infants and children. The main foodstuffs contributing significantly to its total dietary intake are drinking water, rice (and its products),...
