“…In this study we assumed a 100% bioavailability for iAs, as it has been assumed by others (Adomako et al, 2011;Batista et al, 2011;Jorhem et al, 2008;Meharg et al, 2009;Meliker et al, 2006;Mondal and Polya, 2008;Qian et al, 2010;Torres-Escribano et al, 2008;Tsuji et al, 2007;Ye et al, 2012). However, Laparra et al (2005) have shown that only 3.9-17.8% of the bioavailable iAs may be bioaccessible.…”

“…Higher levels were reported for rice grown in the US, France, Italy compared to rice from Bangladesh, Venezuela, Egypt, India, Thailand, and Pakistan . Inorganic arsenic (iAs) and dimethylarsenic acid (DMA) dominates in raw rice (Batista et al, 2011;Meharg et al, 2009;Mihucz et al, 2007;Torres-Escribano et al, 2008;Williams et al, 2005;. Proportion of iAs in tAs in rice is also geographically variable ranging from 11% to 93% (Torres-Escribano et al, 2008).…”

a b s t r a c tArsenic species were determined in rice and bulgur samples that were collected from 50 participants who also supplied exposure related information through a questionnaire survey. Speciation analysis was conducted using an HPLC-ICP-MS system. Ingestion exposure to arsenic and associated health risks were assessed by combining the concentration and questionnaire data both for individual participants and the subject population. Inorganic arsenic dominated both in rice and bulgur but concentrations were about an order of magnitude higher in rice (160 ± 38 ng/g) than in bulgur. Because participants also consumed more rice than bulgur, exposures were significantly higher for rice resulting in carcinogenic risks above acceptable level for 53% and 93% of the participants when the in-effect and the proposed potencies were used, respectively, compared to 0% and 5% for bulgur. An inorganic arsenic standard for rice would be useful to lower the risks while public awareness about the relation between excessive rice consumption and health risks is built, and bulgur consumption is promoted.

“…The mean level of arsenic was highest in samples collected from Igbemo (0.059 ± 0.006 µg/g) and lowest in samples obtained from Akure (0.026 ± 0.002 µg/g). The detected mean level of arsenic in rice samples was just 8.2% of the upper limit of 0.5 µg/g allowed in food, and much lower than the reported levels of arsenic in rice samples from Brazil, Taiwan and Thailand which were found to be 0.223 µg/g, 0.383 µg/g and 0.11µg/g respectively (Williams et al, 2005;Batista et al, 2011). The mean level of cadmium was highest in samples collected from Ikole-Ekiti (0.038 ± 0.005 µg/g) and lowest in samples obtained from Ado-Ekiti (0.015 ± 0.003 µg/g).…”

Levels of arsenic (As), lead (Pb), cadmium (Cd), calcium (Ca), chromium (Cr), potassium (K), sodium (Na), and zinc (Zn) in locally cultivated rice consumed in Ondo and Ekiti States of Nigeria were investigated. The rice samples were obtained from six different rice-producing towns; Akure, Ondo, Ado, Igbemo, Ikole and Erinjiyan. The estimated dietary intake (EDI) of these elements were determined and compared with the provisional tolerable daily intake (PTDI) and dietary reference intake (DRI) values for toxic and essential elements respectively. The measured mean levels of Pb, As, Cr, Cd, Zn, Na, Ca and K were 0.047 ± 0.007, 0.041 ± 0.004, 0.570 ± 0.032, 0.026 ± 0.003, 7.856 ± 0.659, 42.15 ± 0.191, 337.11 ± 0.315, and 2650.09 ± 0.337 µg/g respectively while the average EDI were 00.101 ± 0.042 µg/day, 0.088 ± 0.14µg/day, 1.234 ± 0.045 µg/day, 0.057 ± 0.002 µg/day, 0.017 ± 0.071 mg/day, 0.091 ± 0.013 mg/day, 0.73 ± 0.018 mg/day and 5.742 ± 0.337 mg/day respectively. The EDIs were not significantly higher than the reference values for the elements except Cr. Also the rice samples were not rich enough in sodium, calcium and potassium compared to the dietary reference intakes for these elements. It is recommended that rice diets should be supplemented with other food items such as meat, fruits and vegetables.
