重金属离子与消毒药物对澳洲龙纹斑幼鱼的急性毒性
Acute Toxicities of Disinfectants and Metal Ions on Juvenile Murray Cod, Maccullochella peelii peelii
摘要
Abstract
Acute toxicities of disinfectants and metal ions in varied concentrations on juvenile Murray cod,Maccullochella peelii peelii,was studied.The juvenile fish were tested for acute toxicity by the chemicals to provide crucial information for the aquaculture and diseases control.Solutions with a concentration gradient of copper sulfate,zinc sulfate,cadmium chloride,lead nitrate,chlorine dioxide,povidone-iodine,potassium permanganate,formaldehyde,and salt were prepared for the experiment.Using a hydrostatic method,the 24 h half lethal (LC50),absolute lethal (LC100) and safe (SC) concentrations of the disinfectants or metal ions on Murray cods were determined.The results showed SC for the fish on copper sulfate,zinc sulfate,chloride cadmium,lead nitrate,chlorine dioxide,povidone-iodine,potassium permanganate,formaldehyde,sodium chloride to be 0.122 3 mg ·L-1,0.5713mg·L-1,0.0200mg·L-1,0.4612mg·L-1,5.0300mg·L-1,0.5324mg· L-1,0.9589mg · L-1,6.960 0 mg· L-1,and1.584 0 mg· L-1.respectively.The severities of toxicity of the4 metal ions and5 disinfectants on the juvenile Murray cods ranked as:chloride cadmium＞ copper sulfate＞ zinc sulfate＞ povidone iodine＞potassium permanganate＞chloride cadmium＞sodium chloride＞chlorine dioxide＞formaldehyde.关键词
