Flow-through acute lethal toxicity tests were conducted with kelthane, dursban, disulfoton, pydrin and permethrin using rainbow trout Salmo gairdneri and fathead minnows Pimephales promelas in Lake Superior water. Pydrin was the most toxic pesticide tested to both species of fish and was followed in order of decreasing toxicity by permethrin, dursban, kelthane and disulfoton. Rainbow trout were more sensitive than fathead minnows to all five pesticides. The 96-h LC50 values micrograms/liter for rainbow trout and fathead minnows, respectively, were: pydrin, 2.1 and 5.4; permethrin, 7.0 and 15.6; dursban, 8.0 and 203.0; kelthane, 210.0 and 510.0 and disulfoton, 3020.0 and 4000.0.
