In Bangladesh, well water is high in arsenic and is used both for
irrigating elds and drinking. Uptake of arsenic by rice plants
could be sti ing crucial micronutrients such as selenium in rice
grains. This is bad news for people in Asia, whose diet is
primarily rice, because selenium helps cleanse toxic arsenic from
the body. Exposure to arsenic, a class 1 carcinogen for which there
is no safe dose, affects hundreds of millions of people worldwide.
Chronic exposure leads to diseases such as skin and bladder cancer.
Although most research has focused on naturally occurring arsenic
in well water, new studies hint that food could be a signi cant
source of arsenic. The arsenic composition of rice typically ranges
from 100 to 500 micrograms per kilogram (ug/kg), and many people in
Asia eat at least 200 g/day of rice. Therefore, the levels in rice
commonly lead to arsenic exposures at or above the WHO limit.
