FernandoOlivia 1200821Effects of the Water Soluble Fractions (WSF) of diesel on the growth responses of a marine microalgae, Chaetoceros calcitrans were studied in the controlled laboratory conditions for a short-term period of 96 h. Differential growth responses were observed at comparatively lower diesel concentrations (5, 10, 20 and 40%), though higher concentration (80%) was found to suppress the growth effectively. The actual concentration of the WSFs were analyzed using a spectrofluorometer and a 96 h-EC50 value was found to be 36.56-38.02 mg of diesel per liter of sea water. It has been concluded that diesel spills are not very much suppressive to the microalga, if not a major spillage accident.]]>Anderson, J.W., J.M. Neff, B.A. Cox, H.E. Tatem and G.M.
