Abstract

 

 

In this study the acute toxicity of lead nitrate (Pb(NO3)2) to Daphnia magna Straus was investigated in a static bioassay. After 24 h the mobility of daphnids were examined and immobile ones were counted. The 24 h EC50 of lead nitrate to D. magna was found as 0.44 mg/L. According to Behrens-Karber method the 24 h EC50  of lead was found as 0.51 mg/L.

 

Key words: Lead, daphnid, toxicity, EC50, probit.
