Of the various industrial set-ups polluting the environment with mercury, chloralkali factories are the most important. The presence of mercury in the exhaust air has been reported, and the presence of a large amount of mercury has also been reported in the solid waste of chloralkali factories. The loss of mercury from the culture medium through microbial activities under laboratory conditions has been established. The present investigation deals with the effect of mercury contaminated solid wastes of chloralkali factories on the growth of Azolla (A water-weed) and loss of mercury from the medium under field conditions following its culture. It was noticed that the discharge of chloralkali greatly affected the local vegetation including cultivated cereals. An attempt was, therefore, made to reclaim the waste soil with Azolla.
