Abstract

The toxicity of the antifouling biocides Irgarol 1051, Diuron, Chlorothalonil, Dichlofluanid, Sea-nine 211, Copper pyrithione, Zinc pyrithione, Ziram and Zineb were evaluated on Nitzschia pungens and Artemia larvae. Results showed that EC₅₀ for Irgarol 1051 was 0.586μgl^-1 was the strongest effect on N. pungens following by Copper pyrithione (4.908μgl^-1), Ziram (5.421μgl^-1), Zinc pyrithione (5.513μgl^-1), Diuron (6.640μgl^-1), Zineb (232.249μgl^-1), Sea-nine 211(267.368μgl^-1), Chlorothalonil (360.963μgl^-1) and Dichlofluanid (377.010μgl^-1) in 96h. In Artemia larvae, the biocides were evaluated the LC₅₀ for larval survivals at 48h. Sea-nine 211 and Copper pyrithione were 0.318 and 0.319mgl^-1. Chlorothalonil, Zinc pyrithione and Ziram were 2.683, 3.147 and 4.778mgl^-1. Irgarol 1051, Diuron, Zineb and Dichlofluanid were 9.734, 30.573, 41.170 and 154.944mgl^-1. These results provide baseline data concerning the toxicity of antifouling biocides against marine environment.
