• Inorganic arsenic (As(i) ) in rice (Oryza sativa) grains is a possible threat to human health, with risk being strongly linked to total dietary rice consumption and consumed rice As(i) content. This study aimed to identify the range and stability

Sulfur-Containing Arsenical Mistaken for Dimethylarsinous Acid [DMA(III)] and Identified as a Natural Metabolite in Urine: Major Implications for Studies on Arsenic Metabolism and Toxicity

Autor: Bruce F. Milne, Marcel Jaspars, Andrea Raab, Jörg Feldmann, Helle Rüsz Hansen

Publikováno v: Chemical Research in Toxicology. 17:1086-1091

It is vital that methylated trivalent arsenicals [MA(III) and DMA(III)] are described and characterized unequivocally due to their high toxicity. Two different ways of generating the methylated trivalent arsenicals have been practiced-reduction of th
