title: Effects of aerial sumithion spraying on juvenile atlantic salmon (Salmo salar L.) and brook trout (Salvelinus fontinalis Mitchill) in Newfoundland.
abstract: Forest sprays of the organophosphate pesticide, Sumithion, at 2 or 3 oz/acre were less acutely harmful to fish than sprays of the chlorinated hydrocarbon pesticide DDT have been in the past. Possible indirect or chronic effects cannot be discounted.
