Abstract: The acute toxicity of mercury (as HgSO\-4),cadmium (as CdCl\-2) and lead (as Pb(NO\-3)\-2) to larvae of abalone (six months old) was studied with the static test method at 14～16 ℃. The results show that the toxicity sequence of three heavy metals to larvae of abalone is Hg>Cd>Pd. The LC\-\{50\} (median lethal concentration) of 24,48 and 96 h for Hg to larval abalone are 0.282,0.164 and 0.123 mg/L respectively. The LC\-\{50\} of 24,48 and 96 h for Cd to larval abalone are 8.68,7.10 and 4.60 mg/L respectively. No abalone was lethal in 10 mg/L Pb seawater (the Pb solution was saturated) for 96 h. The toxic symptoms of Hg and Cd to abalone are different. The combined toxicity of Hg and Cd to abalone shows antagonism.
