Abstract

acutus were tested for sensitivity to varying concentrations of seven insecticides and three fungicides . The growth rates of the organisms were considerably reduced by BHC and DDT analogues even at low concentrations of 500 ppb and 1 ppm . Lindane above 5 ppm and Technical BHC and DDT at 100 ppm were lethal to this alga . Of the three fungicides, TMTD (Tetra Methyl Thiurum Disulfide) was most toxic resulting in death of the culture at 10 and 100 ppm. Blitox (Copper-oxy chloride and Zineb (Zinc Ethylene-Bis dithiocarbamate) considerably retarded growth at all concentrations . This alga was more sensitive to hindane, BHC (Technical), DDT and TMTD . The growth rate appeared to be influenced by the concentration of pesticide present in the algal culture . As Scenedesmus acutus is being considered as a source of Single Cell Protein (SCP) for human consumption, knowledge on the sensitivity of this alga to pesticide contamination will be useful.
