Rice can contain a relatively high amount of arsenic (As). We evaluated total and inorganic As concentrations in 39 samples of different types of rice sold in Spain. The analyses were performed in raw rice and in rice cooked by boiling to dryness in water spiked with As(V) (0.1-1 microg mL(-1)). In raw rice, inorganic As represented 27-93% of total As: total As = 0.188 +/- 0.078 microg g(-1) dry weight (dw); inorganic As = 0.114 +/- 0.046 microg g(-1) dw. After cooking, the rice retained… CONTINUE READING
