| Abstract | ||
| The toxicity and accumulation of the heavy metals, Lead and Cadmium in a common filamentous green alga, Cladophora crispata. were studied. These algae were cultured in a modified Chu-No.10 medium, which was supplemented with 5, 10, 20 and 40 mg/l of lead and 0.5, 1, 2 and 4 mg/l of cadmium. Growth rate of alga Sp. inhibited by metals concentration when the exposure time and concentration were increased. Cadmium was more toxic than lead. The accumulation study showed that there was significant 121.65ppm for cadmium and 105.11 ppm for lead increase of metal level in algal tissue when the exposure time and concentration were increased. | ||
