Description of key information
Acute toxicity to fish:
Acute toxicity of the compound reaction mass of m-terphenyl and o-terphenyl was investigated according to OECD Guideline 203.
Following results have been obtained after an exposure period of 96 hours: LC50 = 6.7 µg/L (95% confidence limits: 6.0 to 7.4 µg/L), NOEC = 6.0 µg/L, LOEC = 7.4 µg/L.
Acute toxicty to aquatic invertebrates:
Acute toxicity of the compound reaction mass
of m-terphenyl and o-terphenyl was investigated under semistatic
conditions. The test was performed according to OECD Guideline 202
(2004) and EU Method C.2 (2008).
Results: Exposure of Daphnia magna to
the test item gave EC50 (48 h) values based on the geometric mean
measured test concentration of greater than 0.0096 mg/L. The NOEC (48 h)
was 0.0096 mg/L. No immobilization was observed throughout the test.
This study showed that there were no toxic effects at saturation.
Toxicity to aquatic algae:
A study according to OECD Guideline 201 was
performed to determine the aquatic toxicity of the test compound to
green alga Pseudokirchneriella subcapitata.
Results for growth rate (72 h): EC50: >0.027 mg/L*, EC20>0.027 mg/L*,
EC10: 0.026 mg/L, LOEC: 0.015 mg/L, NOEC: 0.027 mg/L. *:It was not
possible to calculate ErC20 or ErC50 values as at the maximum attainable
test concentration of 0.027 mg/L, no more than 18% inhibition of growth
rate occurred.
Results for yield (72 h): EC50: 0.027 mg/L, EC20>0.026 mg/L, EC10: 0.025
mg/L, LOEC: 0.015 mg/L, NOEC: 0.027 mg/L.
Additional information
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.
