Description
Summary:Spatiotemporal distribution of arsenic (As) species of oysters in the coastal area of southwestern Taiwan was evaluated. The measured concentrations of total As and As species in oysters were statistically analyzed for various production areas, seasons and sea locations. The total As contents in oysters in the regions were 9.90 plus or minus 3.68 mu g/g during 2002-year. For the spatial variation, the total As, As(III) and DMA contents of oysters were the highest in Putai, but the AsB contents were lowest in Putai. The total As contents of oysters living in inner sea spatiotemporally exceeded those living in outer sea. The ratios of inorganic As concentrations to total As concentrations spatiotemporally ranged from 0.82 to 1.88 percent, with a mean of 1.26 percent.
