Amphibians, which can live in aquatic and terrestrial environments, are a good indicator of pollution these areas. Although frog leg is not consumed frequently some cuisines, including Turkey, it important terms evaluating metal accumulation since preferred as human food many European countries. In this study, the quantities trace elements (Cd, Pb, Cu, Zn, As, Co, Cr, Ni, Mn, V) were measured e...

Here, we evaluated the levels of As, Hg, Pb, and Cd in shark meat sold along Amazon Coast Brazil used nitrogen stable isotope values to determine trophic position assess element biomagnification. From market samples, a total 13 species were identified via molecular analysis, including those listed as endangered vulnerable by IUCN Red List. Arsenic was present significantly higher concentrations...

We provide an update of the issues surrounding health risk assessment of exposure to cadmium in food. Bioavailability of ingested cadmium has been confirmed in studies of persons with elevated dietary exposure, and the findings have been strengthened by the substantial amounts of cadmium accumulated in kidneys, eyes, and other tissues and organs of environmentally exposed individuals. We hypoth...

Arsenic contamination in a large area of agricultural fields on the Guandu Plain of northern Taiwan was confirmed in a survey conducted in 2006, but research concerning the relationship between bioavailable As concentrations in contaminated soils and crop production in Taiwan is not available. Pot experiments were conducted to examine the growth and accumulation of As in four vegetable crops gr...

Knowledge of toxic metal concentrations in meat products is important for assessing their risk on health when consumed. Levels of such metals have neither been questioned, nor the appropriate total dietary studies (TDS) have ever been conducted in Lebanon to carry out proper risk assessments. The study reports on the levels of lead (Pb) and cadmium (Cd) in canned and processed meats sold in the...

Human hair of different age groups and foodstuff samples were collected in Beijing, China. The concerned metals-Cd, Cr, Pb, As, and Hg-were analyzed, and the metal levels in relation to age, gender, and dietary intake were further assessed. Results showed the highest level of the metals was shown by Pb, with an average concentration of 1.557 ± 0.779 mg/kg, followed by Cr (0.782 ± 0.394), Hg (0....

Bioavailability and hence bioaccumulation of heavy metals in fish species depends on seasonal conditions causing different risks levels to human health during the lifetime. Mercury, cadmium and lead contents in fish from Chihuahua (Mexico) water reservoirs have been investigated to assess contamination levels and safety for consumers. Muscle samples of fish were collected across the seasons. Le...

This study examines the total Hg contamination in soil and sediments, and the correlation between the total Hg concentration in soil and vegetables in two small scale gold mining areas, São Chico and Creporizinho, in the State of Para, Brazilian Amazon. Total Hg values for soil samples for both study areas are higher than region background values (ca. 0.15 mg/kg). At São Chico, mean values in s...

The samples of 4 mushroom species from the genus Leccinum ((Leccinum pseudoscabrum (Kallenb.) Šutara, scabrum (Bull.) Gray, duriusculum (Schulzer ex Kalchbr.) Singer, and albostipitatum den Bakker & Noordel) were picked 6 forested areas Slovakia in 2020 (Čačín – Jelšovec, Hliník Hronom, Kurima Taraš, Mníšek nad Popradom, Snina Štefekovo, Žákylské pleso). Total mercury content soil parts was...

Ninety-five wild forage plants (belonging to 22 species of 18 families) and their corresponding rhizosphere soil samples were collected from wastelands a large-scale abandoned Hg mining region for total (THg) methylmercury (MeHg) analysis. The plant communities on the dominated by Asteraceae, Crassulaceae, Polygonaceae families. THg MeHg concentrations in varied widely range 0.10 13 mg/kg 0.19 ...
