Chromium in the form of hexavalent chromium (VI) has been used in some industry including leather tanning industry. The chemical has been known to be harmful to living organisms. Therefore, it is important to treat wastewater from leather tanning industry before being discharged to the environment. The aim of this study is to examine ecophysiological strategies of waterhyacinth (Eichhornia crassipes) to tolerate Cr6+ accumulation in its tissue, compared to sensitive species water lettuce (Pistia stratiotes). The plants were cultivated in containers containing Hoagland medium and treated with some variation of Cr6+ concentrations of Cr6 i.e. 0, 40, 80 and 120 ppm for 14 days. Some parameters including CAT (catalase), Ascorbate peroxidase (APX), chlorophyll concentration and proline in the plants were measured. The biomass yield of plant in Cr6+ stress was negative (-0.732 to -1.84 g/week) which indicated both E. crassipes and P. stratiotes reduced their growth.
