Short-term toxicity to fish
Administrative data
Link to relevant study record(s)
Description of key information
Data on Short Term Toxicity to Fish was available for 2 streams within this Category. The toxicity range for 96h LC50 was 1.0-4.4 mg/l, LL50 was 1.1 -5.6mg/l (WAF)
Key value for chemical safety assessment
Additional information
All short term toxicity to fish data came from ExxonMobil (2003).
CAS No 68513 -69 -9 and 68921 -67 -5 The 96-hour LL50 was reported to be 1.1 mg/l. LC50 was reported to be 1.0 mg/L. This study is GLP compliant and follows a standard guideline. It is considered reliable and suitable for use as a key study.
CAS No 68513 -69 -9 The 96-hour LC50 was reported to be 4.4 mg/L and the 96-hour LL50 was 5.6 mg/L. This study follows a standard guideline and is GLP compliant.There were some deviations from the protocol but these did not affect the outcome of the study. This study is considered acceptable for use as a supporting study.
