AB  - The concentrations of arsenic (As) species in 19 food composites prepared from 
      159 food items purchased in Shizuoka city, Japan, were determined (1) to estimate 
      total daily intake of inorganic As (InAs) and some organic As species and (2) to 
      determine food contributing to total daily InAs intake. As analysis included 
      extraction of As species with a synthetic gastric juice (0.07 mol/L HCl + 0.01 % 
      pepsin) from food composite and high-performance liquid chromatography-high 
      efficiency photo-oxidation-hydride generation-inductively coupled plasma mass 
      spectrometry. InAs was detected in 9 of 19 food composites at a concentration of 
      0.423-450 ng As/g fresh-weight. Daily intake of InAs from cereals was greatest 
      (13 mug/person/day) followed by algae (5.7 mug/person/day), and the intake from the 
      two categories constituted 90 % of the total daily InAs intake of adults 
      (21 mug/person/day on a bioaccessible-fraction basis and 24 mug/person/day on a 
      content basis). Analysis of individual food items showed that rice and hijiki 
      contributed virtually 100 % of InAs from cereals and algae, respectively. The 
      present survey indicated that InAs from rice and hijiki consumption contributed 
      to total daily InAs intake and consequently to significant cancer risk of the 
      general Japanese population. Daily intake of some organic forms of As and their 
      contributing food categories was also estimated.
