4. ECOTOXICITY ID: 106-44-5
DATE: 24.05.2004
Unit : mg/l
LC50 : = 1.4
Analytical monitoring : no data
Method : other: according to the method described by Parkhurst et al. 1977
Year : 1979
GLP : no
Test substance : other TS: p-cresol, no purity reported
Method : Parkhurst BR, Gehrs CW, Rubin IB (1977): Proceedings of ASTM
2nd Annual Symposium on Aquatic Toxicology, 122-130
Test condition : Daphnia magna used in the test were adults.
100-ml test beakers were filled with 80 ml test solution and
4 daphnia. All the tests were run in triplicate.
Temperature during the test: 25 +/- 0.5°C
12h light/dark cycle
Test solution was prepared with filtered spring water (pH
7.8 alkalinity mg/l, hardness 140 mg/l)
Control beakers were used
48h-EC50 values were obtained by PROBIT
Test substance : The test substance was obtained from an effluent
Reliability : (3) invalid
Methodological deficiencies (method description is in the other reference
from the same author). Age of daphnias used in the test is not clearly
specified: test daphnias were "adults" (in the OECD guideline a 24h-old
daphnia is suggested); temperature during the test was 25°C (in the
guideline is suggested: 18-22°C); 12 daphnia were used for each test
concentration (in the guideline 40 daphnias are suggested)
