EC number: 284-892-9
CAS number: 84989-04-8
The fraction of tar acid rich in 3- and 4-methylphenol, recovered by distillation of low-temperature coal tar crude tar acids.
NOEC (21 d) = 1 mg/L on Daphnia magna (guideline proposal of the German Umweltbundesamt, 1984)
Long-term tests to aquatic
invertebrates are only available for p-cresol. No data is available on
o-cresol and m-cresol. Since
there is no significant exposure of cresols to the aquatic compartment
(refer to exposure assessment in CSR) long-term testing of o-cresol and
m-cresol to aquatic invertebrates can be omitted (section 3 of REACH
The long-term toxicity of p-cresol to
aquatic invertebrates was determined by a test according to the
preliminary guideline proposal of the German Umweltbundesamt from1984.
The 21d-NOEC was 1 mg/L for Daphnia magna (Kuehn et al. 1988,
1989). In a non-guideline study
with 4 generations on the planarian Dugesia tigrina an 80-d EC10
of 2 mg/L was measured (Solki and Piontek 1987).
