A Global Review of Cadmium, Mercury, and Selenium in Sharks: Geographical Patterns, Baseline Levels and Human Health Implications

Is restricting catch to young sharks only more sustainable? Exploring a controversial management strategy for bull, tiger, blue and bonnethead sharks

“…Another advantage of restricting harvest to juvenile sharks relates to human health concerns, because high‐trophic level, long‐lived predators, like sharks, are high in mercury and other heavy metals (Rumbold et al, 2014; Rodríguez‐Gutiérrez et al, 2020; Amezcua et al, 2022). Such harmful substances often exceed safe concentrations for human consumption, particularly for larger individuals of long‐lived species (Amezcua et al, 2022; Garcia Barcia et al, 2020; Maurice et al, 2021; Rodríguez‐Gutiérrez et al, 2020). By contrast, smaller sharks are more likely to have lower concentrations of heavy metals than their larger counterparts (Pethybridge et al, 2010; Rodríguez‐Gutiérrez et al, 2020; Lara et al, 2022).…”

Total Selenium Level and Its Distribution between Organs in Beef Cattle in Different Selenium Status

“…Although many studies have been conducted on the tissue distribution of Se in various animal species [30,31], there is little data on how it is affected by dietary Se status in beef cattle [8,22]. The present study is the first to be carried out in Poland, an area known to suffer from Se deficiency.…”

Selective and efficient detection of Pb2+ in aqueous solution by lanthanoid-organic frameworks bearing pyridine-3,4-dicarboxylic acid and glutaric acid

“…Cd 2+ exposure at low level over an extended period can result in kidney, bone, and lung diseases. 6 Mercury is one of the most serious contaminants threatening our waters because it is a potent neurological poison to fish, wildlife, and humans. 7 Ni 2+ and Mn 2+ ions are not only indispensable biological ions for human beings but are also utilized widely in industrial production.…”
