OECD <strong>SIDS</strong> PROPYLENE GLYCOL<br />
4. Ecotoxicity<br />
Id 25265-71-8<br />
Date 30.05.2001<br />
Test substance: no compositional details given<br />
Exposure Period: 48 hrs<br />
Method: No methodology given.<br />
Clawed toads exposed to serial dilutions of test substance with Dutch<br />
standard water as the dilution water source.<br />
Study conducted in 1 L all-glass covered aquaria with 3-4 week old larvae<br />
at a study temperature of 20 ± 1 ºC.<br />
Calculation of LC50<br />
Calculated as projection from least square linear regression on log<br />
transformed nominal concentration data and probit transformed percent<br />
effect data.<br />
Analytical monitoring: None<br />
Result : Mortality measured after 48 hours of exposure resulted in determination of<br />
an LC50 of 3,181 mg/L.<br />
Source : Lyondell Chemical Co. Houston, Texas<br />
Conclusion : The 48-hour LC50 (TLm) for the clawed toad was determined to be 3,181<br />
mg/L.<br />
Reliability : (2) valid with restrictions<br />
Details on the test procedure and study results are not provided. No<br />
analytical measurement of test substance concentrations in the test<br />
solutions or sample purity were conducted.<br />
