Metabolic transformation and urinary excretion of selenium (Se) in rats fed a Se-enriched defatted rapeseed (Brassica napus, L.) diet.
Zuzana Čadková et al.
Metallomics : integrated biometal science, 10(4), 579-586 (2018-03-21)
Se-Enriched defatted rapeseed (Se-DRS), a by-product of rapeseed oil production, is high in Se. This study aimed to detect possible changes in Se-metabolism after Se-DRS consumption and to assess its suitability as a Se supplement in monogaster feed. In this
Sunlight Promotes Fast Release of Hazardous Cadmium from Widely-Used Commercial Cadmium Pigment.
Huiting Liu et al.
Environmental science & technology, 51(12), 6877-6886 (2017-05-17)
Cadmium pigments are widely used in the polymer and ceramic industry. Their potential environmental risk is under debate, being the major barrier for appropriate regulation. We show that 83.0 ± 0.2% of hazardous cadmium ion (Cd
Selenolanthionine is the major water-soluble selenium compound in the selenium tolerant plant Cardamine violifolia.
Eszter Borbála Both et al.
Biochimica et biophysica acta. General subjects (2018-01-15)
Selenium hyperaccumulation in plants often involves the synthesis of non-proteinaceous methylated selenoamino acids serving for the elimination of excess selenium from plant metabolism to protect plant homeostasis. Our study aimed at the identification of the main selenium species of the
Experimental paradigm for in-laboratory proxy aquatic studies under conditions of static, non-flow-through chemical exposures.
