Arsenic Metabolites Excreted into the Human Urine after Hijiki Intake

Abstract

We intended to investigate effects of Hijiki intake on biochemical modification of the arsenic ingested by the human body. The 24 hour-urine was collected either before or after starting the Hijiki diet, and urinary arsenic components were analyzed with an HPLC/ICP-MS instrument. Some differences in the urinary arsenic components were observed between before and after starting the Hijiki diet, but the differences were not the same in each individual, probably owing to different physiological or biochemical conditions.
