Although fish is an important source of nutrients, including some the healthiest proteins, long-chain fatty acids, and essential selenium, species at top food chain frequently contain large amounts toxic mercury (Hg). The provisional tolerable weekly intake (PTWI) Hg from consumption calculated total concentration assuming that all speciated as organic methylmercury (MeHg). Using high energy-re...

Background and purpose: Mushrooms are highly nutritive, since they are low in calories and contain significant amounts of vegetative proteins, vitamins, minerals, amino acid, and fiber. Mushrooms might be contaminated by heavy metals such as lead, cadmium, chromium, etc. This contamination depends on type of mushrooms, their physiology, and ecosystem. The present study aimed at determining the ...

The aim of this study was to examine the contamination, accumulation, and distribution of mercury in fruiting bodies by Leccinum versipelle fungus collected from distant sites across Poland. Mercury was determined using validated method by cold-vapor atomic absorption spectroscopy after direct sample matrix combustion. A large set of data gained using 371 fruiting bodies and 204 soil samples re...

Because there is a great difference between the toxicity of inorganic arsenic (As) and organic As in food, the JECFA has set a PTWI value for inorganic As (iAs) rather than for total As. The difference in As toxicity makes it necessary to extract iAs completely from food samples for toxicological analysis, but complete extraction of As from most foods including seaweed has not been achieved to ...
