Rice samples (n=157) were collected from four large markets in Kandal Province and analysed for As using inductively coupled mass spectrometry. The mean As concentration for Cambodian rice (0.185µgg−1, range 0.047-0.771µgg−1) was higher than that for imported rice from Vietnam and Thailand (0.162 and 0.157µgg−1, respectively) with mean As concentrations highest in rice from Prey Veng Province resulting in a daily dose of 1.77µgkg−1b.w.(body weight)d−1. Between unmilled rice varieties, Cambodian-grown White Sticky Rice had the highest mean As concentration (0.234µgg−1), whilst White Sticky Rice produced in Thailand had the lowest (0.125µgg−1), suggesting that localised conditions have greater bearing over rice As concentrations than differences in As uptake between individual varieties themselves. A rice and water consumption survey for 15 respondents in the village of Preak Russey revealed mean consumption rates of 522gd−1 of rice and 1.9Ld−1 of water. At water As concentrations >1000µgL−1, the relative contribution to the daily dose from rice is low. When water As concentrations are lowered to 50µgL−1, daily doses from rice and water are both generally below the 3.0µgkg−1b.w.d−1 benchmark daily limit for a 0.5% increase in lung cancer, yet when combined they exceeded this value in all but three respondents.
