Title Sensitivity of the alga Scenedesmus acutus to some pesticides.
 
Creator Krishnakumari, M. K.
 
Subject 26 Pesticide Chemistry
01 Algae
 
Description 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.
