Abstract:
Objective To know the effects of laver intake on arsenic species in urine of people, and investigate the characteristics of arsenic metabolism. Methods The urine samples were collected from 24 subjects who had laver available on markets, arsenic species in urine samples were detected with hydride generation atomic fluorescence spectroscopy. Results There was a significant increase of urinary iAs seventy-two hours after laver intake except one and forty-eight hours, increase of MMA seventy-two hours after laver intake except one and twelve hours, and increase of DMA from the first hour to the 72nd hour in male group. There was a significant increase in the urinary iAs seventy-two hours after laver intake except three, five and forty-eight hours, increase of MMA seventy-two hours after laver intake except five and twelve hours, increase of DMA from one to seventy-two hours after laver intake in female group. Conclusion The urinary concentration of DMA is significantly higher in female group compared with male group after laver intake in the same weight and urinary DMA increases in the beginning, after that decreases gradually.
