Description of key information

The 96h-LC50 for carp exposed to 2,4,7,9-TETRAMETHYL-5-DECYNE-4,7-DIOL was already
reached after 24 hours of exposure and was 42 mg/l with 0% mortality at 32 mg/l (LC0) and
100% mortality at 56 mg/l (LC100).


For daphnids the 48h-EC50 was 91 mg/l based on average exposure concentrations with a 95% confidence interval between 81 and 110 mg/l.


For the total test period of the algal toxicty test, the EC50 for growth rate reduction (ErC50: 0-72h) was 82 mg/l with a
95 % confidence interval ranging from 39 to 170 mg/l. The EC10 for growth rate reduction
(ErC10: 0-72h) was 15 mg/l with a 95 % confidence interval ranging from 7 to 30 mg/l.
