The present study was undertaken to determine the level of contamination of drainage water of an experimental ricefield by two insecticides, γ H.C.H. and Parathion, two herbicides Moli-nate and Propanil and 3,4 D.C.A. a degradation product of Propanil. Changes in the concentraitons of the chemicals and of total discharge of the drain water were recorded, and thus the total amount of each chemical released over the growth season was calculated. The consequences of these discharges on aquatic ecosystems recieving drain water are discussed.Cette étude porte sur la contamination des eaux de drainage d’une rizière expérimentale de un ha par deux insecticides, le γ H.C.H. et le Parathion, et deux herbicides le Molinate et le Propanil, ainsi qu’un...
