The effect of heavy metal on Cltlorella vulgaris, Scenedesmus obliquus and Anabaena Flos-aquae
In this survey two species of chlorophyta (Chlorella vulgaris and Scenedesmus obliquus ) and one species of blue-green algae (Anabaena flos- aquae) were exposed with heavy metal (zinc) under lab condition ( temp. 25± 2°C,light 3500± 350 lux) for 96 hours. After this time, these species were counted with hemocytometer and based on probit analysis method and was determined ECIO, EC50 and EC90. Amount of EC50 for C vulgaris, S. obliquus and A.flosaquae were 0.134,0.047 and 0.093 mg/lit, respectively and this subject was distincted that S obliquus has more endurance than other species. Mac value of zinc for these species (C. vulgaris, S. obiquus and A.flos-aquae ) were 0.0134, 0.0047 and 0.0093 mg/l respectively. Regression coefficient was 92-98 percent between concentration logaritm of zinc and decrease of these species density.
