Bioremediation of arsenic toxicity by algae in rice culture
S.M. Imamul Huq, Marzia Binte Abdullah and J.C. Joardar

A rice variety (BRRI Dhan-28) receiving arsenic-contaminated irrigation water ranging from 0 to 2.0 mg As/L, and grown with and without algae, showed that the presence of algae in the growth medium reduces As accumulation in rice. The pot experiment showed that algae could reduce accumulation of arsenic in rice plants by as much as 71%. Algal growth was also found to depress arsenic accumulation in soil.

Key words: algae, arsenic, bioremediation, rice
