The effect of the insecticides Hungaria L-7, Dimecron-50, Thimet-10 G and Satox 20 WSC containing lindane, phosphamidon, phorate and trichlorfon, respectively, as active ingredient was investigated on the survival and pumping behaviour of the fresh-water mussel Anodonta cygnea L. The shortening of active periods was used as indicator of the sublethal effects. Hungaria L-7, Thimet-10 G and Satox 20 WSC caused significant inhibition of the filtering activity, while Dimecron-50 was less effective. Fifty per cent shortening of active periods required 6 x 10-3 g/l Hungaria L-7, 8 x 10-3 g/l Thimet-10 G and 2 x 10-2 ml/l Satox 20 WSC. Thimet and Satox were lethal at 10-1 g/l and 1 ml/l concentrations, respectively. Although the mechanism of the effect can be different with various substances, the results have shown, that monitoring of the activity of mussels can be a suitable test for the biological indication of water pollution.
