of the Activated Sludge, Respiration Inhibition Test of Novares LA 300
Loading rate (mg/L)
[mg O2/(L x h)]
* With reference to the validity criterion of OECD-Guideline 209 that
a deviation of respiration rates of the two controls of ≤15
result of inhibition of theTest
Item of 6.5 % was
not regarded as a significant inhibition.
Due to substance properties, toxicity to microorganisms is
determined based on loadings. The effective loading resulting in no
observable effect (NOELR) or in 50 % inhibition of total respiration
(EL50) was identified to be 100 mg/L or > 100 mg/L test substance,
The substance 'Oligomerisation and alkylation reaction products
of 2-phenylpropene and phenol' (OAPP) (previous name phenol,
methylstyrenated) is a UVCB substance with a complex and within limits
variable composition. Water solubility is low and not clearly defined
due to the differing solubility of individual components. Depending on
the quantity used, concentration of material dissolved in saturated
water samples is variable. Therefore, water accommodated fractions
(WAFs) have been used in aquatic toxicity tests. Thus, results are
presented as loadings (EL50, NOELR).
Toxicity to microorganisms has been tested in a valid GLP
guideline study (OECD TG 209) with one concentration (loading) of OAPP
(LA 300) (limit test). The NOELR was determined to be 100 mg/L while
the EL50 was > 100 mg/L based on inhibition of total respiration.
