Differences in Heavy Metal Accumulation in Wild and Captive Spotted Seal (Phoca largha) Pups in the Bohai Sea

Veterinary Medicine and Science, Volume 11, Issue 3, May 2025.
Due to the massive hunting by humans, the number of spotted seals has decreased dramatically. This study used the ICPMS method to conduct experiments and analysed the correlation between heavy metal accumulations in the bodies of naturally grown spotted seals in the Bohai Sea and artificially raised spotted seals in aquariums and water samples.

Assessment of Elemental Geochemistry: Enrichment and Mobilisation in Acid Sulfate Soils in Southeast Brazil

European Journal of Soil Science, Volume 76, Issue 3, May–June 2025.
ABSTRACT The spatial distribution of acid sulfate soils is influenced by coastal processes, and due to their location, these soils can accumulate significant amounts of trace elements. This study assesses the horizontal and vertical distribution of major elements (Ca, Mg, K, Al, Fe, S), minor elements (P, Ti, Mn), and trace elements (Ba Co, Cu, Cr, Mo,

The impact of school heavy metal exposure on children's gut microbiota: The mediating role of environmental microorganisms

iMeta, Volume 4, Issue 2, April 2025.
Heavy metals are toxic and harmful pollutants that can affect the school environment and the exposed children's health. This study collected dust samples and children's fecal specimens, and performed gene sequencing. We used eXtreme Gradient Boosting to determine the impact of heavy metals on environmental microorganisms and gut microbiota, while using

Health and Ecological Risk From Potentially Toxic Elements in Soils and Extra Virgin Olive Oils From Valdichiana Senese, Tuscany (Italy)

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 2, Page 241-250, April 2025.
ABSTRACT Background Extra virgin olive oils (EVOOs) are widely consumed but rarely analysed for potentially toxic elements (PTEs), whose concentrations in EVOOs can be significantly influenced by contamination in olive grove soils. As food consumption is the main PTE accumulation pathway in humans, thorough investigation on EVOOs is necessary.
