Abstract


Static bioassay test were conducted using commercial grade C Chromium Trioxide to study its toxicity on freshwater mussel, Lamellidens Consobrinus for 24, 48,72 and 96 hrs. The LC50 values were 51.90, 41.57, 28.86, 16.92 ppm after 24,48,72 and 96 hrs. respectively. The results show that the LC50 values decreases with increase in exposure period.
