Urinar y arsenic excretion profiles and associated dietar y factors in Japanese women from a coastal area in Chiba

of iAs, monomethylarsonic acid （MMA）, and DMA were 3.4％, 3.1％, and 91.6％（GM）, respectively, after removing AsBe and other As species from total As. Spearman’ s correlation coefficients showed that seafood and seaweed intake was significantly correlated with％iAs （r=-0.34； r=-0.36, respectively） ,％ MMA （r=-0.25；r=-0.28, respectively）, and％DMA （r=0.33； r=0.37, respectively）. Intake of B vitamins, vitamin C, and soy isoflavones showed significant negative correlations with％iAs and％MMA, but positive correlations with％DMA. Conclusions：Japanese women from the coastal area of Choshi are exposed to low-level iAs. Their intake of B vitamins and vitamin C was associated with proportions of urinary As species. We identified for the first time associations between estimated soy isoflavones intake and the proportion of urinary As species.
