Response of some common fresh water algae to DDT applications

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Growth pattern of 3 common fresh water algaeChlorella, Scenedesmus andSpirulina was studied under the influence of organochlorine pesticide DDT, under laboratory conditions.Scenedesmus was found to be sensitive to DDT doses and growth was inhibited maximally up to 42% after 96h at 5ppm concentration. This alga shows phenotypic variations also in its colony structure at 3 ppm concentration.Chlorella andSpirulina are found to be highly tolerant and no growth inhibition is recorded at all doses of DDT. On the other hand, growth of these algae is promoted over that of control under the influence of DDT.
