Comparison of the effect of Aminopielik D pesticide and its active components on human erythrocytes

In the present work, the effect of Aminopielik D [417.5 g/l of dimethylamino salts of 2,4-dichlorophenoxyacetic acid (2,4-D) and 32.5 g/l of 3,6-dichloro-2-metoxybenzoic acid (Dicamba)] and its active components (used separately and in mixture) on human erythrocytes was examined. The parameters studied were: lipid peroxidation, metHb formation and catalase activity.Aminopielik D used at doses of 100–1000 ppm was found to increase lipid peroxidation, decrease of catalase activity and oxidation of haemoglobin. 2,4-D and Dicamba are present in Aminopielik D in the dimethylamino form; their sodium salts in solution (separately and as a mixture) did not cause such strong effects.A synergistic action of 2,4-D and Dicamba was excluded as the individual compounds caused the same effects as their mixture.Aminopielik D provoked slightly higher changes in the lipid peroxidation and catalase activity than its active components alone and in mixture, which was probably a result of the properties of the additives and interaction of tested systems with the dimethylamino group.
