Agricultural plants represent an important pathway for the movement of potentially toxic trace elements from soil to human beings. Contaminant metals can often accumulate in considerable amount in plant tissues and exceed the levels that are toxic to human and animal system, before they produce visible phytotoxic effects. Chromium is encountered as a metal pollutant in the effluent from tanneries and electroplating industries and accumulates in the top layer of the soil. Chromium in its hexavalent form is highly carcinogenic (NIOSH 1979) and, being highly soluble, readily available to the plants (Bartlett and James 1988). The discovery that an element like selenium counteracts the toxicity, chemical carcinogenesis and may reduce the plant uptake of other toxic metals, has resulted into extensive research on relationship of selenium to other metals in terms of bioavailability (Cary1981) However, studies are mainly confined to zooplankton (Whanger1981, Zakaria et. al. 1993) and, little attention has been paid on selenium-metal interactions in soil plant system. Studies on cadmium-selenium and mercury-selenium interactions in various plants have recently been reported by us. (Shanker, 1995a,b and 1996a, b). Apparently, no study was accessable to us on the possibility of chromium selenium interactions in soil plant system, particularly those with different oxidation states of chromium and selenium.
