DETERMINATION OF MEDIAN TOLERANCE LIMIT (LC50) OF CHANNA PUNCTATA (BLOCH) FOR CADMIUM CHLORIDE
نویسندگان
چکیده
The present investigation was undertaken to investigate the acute toxicity of cadmium, a heavy metal widely detected in aquatic environment due natural effects and anthropogenic activities, freshwater teleost, Channa punctata (Bloch). experiments for bioassay were performed semi-static test condition according standard guidelines. behavioural changes fish observed all tested concentrations metal. data obtained analyzed median lethal (LC50) by SPSS computer software. LC50 values, estimated SPSS, with 95% confidence level found be:20.589 (18.326-23.221), 17.133 (14.840- 19.734), 11.815 (9.696 – 13.850) mg/L 9.908 (7.635-12381) cadmium chloride at 24, 48, 72 96 h exposure, respectively.
