(2006e, 2008) observed that arsenic accumulation in rice is dependent on variety and soil. Not all varieties accumulate arsenic to the same extent. For example, under similar experimental conditions, BRRI dhan 28 was found to accumulate more arsenic than BRRI dhan 29. As usual, in either variety, arsenic accumulation was more from As(III) than from As(V), and root accumulated the maximum.

Arsenic was found to be concentrated primarily in the roots and straws of rice and other cereal crops. The uptake of arsenic is passive (Streit and Stumm, 1993) and is translocated to most parts of the plants. Comparing the arsenic in rice from Bangladesh and Japan, Hironaka and Ahmad (2003) have confirmed that the contents are very similar. However, they mentioned that the rice being produced in arsenic-contaminated areas of Bangladesh contained two to three times more arsenic than that in rice grown in uncontaminated areas.

Very shallow wells (about 10 m) and deep wells (>150 m) are mostly arsenic-safe. In a study in five villages in Sonargaon, Munshiganj, and Comilla covering 30 wells, it was observed that with exceptions of a few, aquifers of depths ranging from 20 to 200 ft contained the maximum amount of total arsenic. The form of arsenic in the groundwater is mostly As(III). In more than 90% of cases, arsenic in groundwater is in this form (Imamul Huq and Naidu, 2003). Of the major aquifers, only the Holocene alluvial aquifers are contaminated; the Pliocene Dupi Tila aquifers are not.
