Description of key information
LC50 (96 h) = 4.4 mg/L on Salmo trutta (static bioassay)
Key value for chemical safety assessment
Additional information
The acute toxicity of o-, m-, and p-cresol to fish was determined in a static bioassay on several freshwater species (Howland, 1969). After an exposure period of 96 h the following most critical toxicity values were found on the single isomers:
o-cresol: LC50 = 6.2 mg/L on Salmo trutta
m-cresol: LC50 = 7.6 mg/L on Salvelinus fontinalis
p-cresol: LC50 = 4.4 mg/L on Salmo trutta
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
