Effect of cadmium-surfactant combined pollution on physiological caracteristics of wheat leaf

Abstract

Abstract: The studies on the effect of combined polution of Cd and three surfactants (linear alkylbenzenesulphonate(LAS), cetyltrimethylammonium bromide (CTAB) and Tween 80 on physiologicalcharacteristics of wheat leaf showed that all of these three whacants could increase the accumulation of cacllnium in wheat leaf. Their effect was in the order of CTAB>LAS>Tween80.The lipid peroxidation level of cells was higher when poluted by Cd-snrtacant than by Cd only.Both the contents of sulfhydry group and chlorophyll were deereased significantly. The ultraviolet absorption value of leaked leaf soution was increased, indicating the destroying effect of thecombined pollution on cell membrane.

Key words: Cadmium, Surfactant, Combined pollution, Wheat, Lipid peroxidation
