on all three trophic levels (fish, daphnia, algae) were performed to
examine the aquatic toxicity of the Sulfomium compound mixture. Algae
turned out to be the most sensitive species revealing an EC50 (72h) of
0.058 mg/L and an EC10 (72h) of 0.029 mg/L based on growth inhibition.
Thus, the mixture is considered to be very toxic to aquatic organisms.
Investigations on the effects towards aquatic invertebrates support this
conclusion by providing an acute EC50 (48h) of 0.138 mg/L for the
immobilisation of Daphnia magna and a chronic LOEC (21d) of 0.27
mg/L based on mortality in a reproduction test. Fish turned out to be
less sensitive, with an measured LC50 (96h) of 14.6 mg/L for the golden
orfe (Leuciscus idus).
