4. ECOTOXICITY ID: 793-24-8
DATE: 11.05.2005
Analytical monitoring : No
Method : other
Year : 1976
GLP : No
Test substance : other TS: Santoflex 13
Method : Monsanto Standard Protocol Oct. 1976
Remark : Test substance concentration not monitored during exposure;
due to the instability of the TS in aqueous solution, the effective TS
concentrations are expected to be lower than the applied nominal
concentrations.
Very low oxygen concentration at the end of incubation
Result : Confidence interval for 96 h LC50 = 0.32 - 0.50 mg/l
24 h LC50 = 0.65 mg/l (0.41 - 1.0 mg/l)
48 h LC50 = 0.45 mg/l (0.31 - 0.65 mg/l)
Test condition : - Carrier: acetone
- 15 l water in all glass vessels, 10 fish per vessel
- Fish length 3.8 cm
- Fish not fed 48 h prior to exposure, nor during exposure
- No aeration oxygen ranged from 8.6 mg/l (98 % saturation) to 0.2 mg/l (2
% saturation) at the beginning and end of exposure, respectively
- Temperature 22 +/- 1 °C
- pH ranged from 7.2 initially to 6.7 at the end of the test
- Observations and mortality counts were made every 24 h following
initiation of exposure
- Statistics: least squares regression analysis to calculate LC 50 and 95 %
confidence intervals
Test substance : Santoflex (KDO3-017) CP-22423, dark red-brown colored
Reliability : (3) invalid
Significant methodological deficiencies
