Abstract
Pot culture experiments containing sand and soil, at two levels of mer cury (2 and 5 mu g mL(-1)) added through irrigation with increasing su pplementation of selenium (selenite and selenate) led to a decrease in the uptake of mercury by tomato (Lycopersicum esculentum) plant. Both the forms of selenium (selenite and selenate) were found to be equall y effective in reducing the mercury accumulation by plants. The observ ed reduction pattern of mercury accumulation in plant tissues has been discussed on the basis of the formation of insoluble HgSe complex in soil-root environment.
