    Abstract:
    The aim of this study was to estimate the dietary intake of arsenic (As) by children and adults from Jinhu area of China. A duplicate diet approach was used to collect diet samples in November and December 2007. The As content was measured by hydride generation atomic fluorescence spectrometry. The As intakes (median) for different group were: children: 0.6 microg kg(-1) bw day(-1) or 6.7 microg kg(-1) bw week(-1); adults: 0.5 microg kg (-1) bw day(-1) or 3.8 microg kg (-1) bw week(-1), none of which exceeded the provisional tolerable weekly intake (PTWI) of 15 microg kg (-1) bw week(-1) for As proposed by the World Health Organization (WHO). The median and maximum of the children group amounted to 44.7% and 125.3% of the PTWI; the values for adults were 25.3% and 118.7%, respectively. There were 3.3% of children whose weekly As intake exceeded the PTWI, and there were 6.7% of adults whose weekly As intake exceeded the PTWI. It is concluded that dietary As intake was safe for most people in Jinhu area, but the high dietary As intake for a minority of people in this area deserves attention.
