Acute Toxicity Test of Five Common Drugs to Veliger of Babylonia areolata Link

The acute toxicity of the five common drugs to the veliger of Babylonia.areolata Link was tested under the conditions of the temperature 29.0～29.5 ℃ and salinity 28.5 to provide some useful information for the correct use of drugs in killing or controlling the harmful micro-organism in the seed production of Babylonia areolata Link.The results showed that the 24 hLC50,48 hLC50,96 hLC50 and Sc of potassium permanganate were 1.71,1.04,0.55 mg.L-1,and 0.115 mg.L-1;the 24hLC50,48 hLC50,96 hLC50 and Sc of benzalkonium bromide were 78.58,28.90,6.06 and 1.17 mg.L-1;the 24hLC50,48 hLC50,96 hLC50 and Sc of Zinc Sulfate were 4.52,2.36,0.62 mg.L-1 and 0.193 mg.L-1;the 24hLC50,48hLC50,96hLC50 and Sc of Nysfungin were 2.36×104,1.46×104,0.64×104 and 0.168×104 U.L-1;the 24hLC50,48 hLC50,96 hLC50 and Sc of formaldehyde were 10.9,7.11,3.66 and 0.908 μL.L-1 respectively.
