| Research Abstract |
MDCK cells and Caco-2 cells did not alter the chemical form of arsenate, arsenite, monomethylarsonic acid, dimethylarsinic acid, trimethylarsine oxide, arsenocholine, and arsenobetaine. The permeability of these 7 arsenic species was studied in a renal tubular epithelial model comprising MDCK monolayer, and was found to be 1-2.5-times higher than that of creatinine. The arsenic compounds in fish and seaweeds were effectively extracted using 50% methanol (extractant) and bead-beating tube (physical extraction method).
