Type : other: not specified
Species : Daphnia magna (Crustacea)
Exposure period : 48 hour(s)
Unit : mg/l
LC50 : 18.8
Limit Test : no
Analytical monitoring : no data
Method : other: according to the method described by Parkhurst et al. 1977
Year : 1979
GLP : no
Test substance : other TS: m-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 : (2) valid with restrictions
Study well documented (method description in an other
reference) with some restriccions. Age of daphnia used in
the test is not clear. Daphnias were "adults" and adults can
be older than 24h (24h is suggested in the guideline);
temperature was 25°C (in guideline is suggested: 18-22°C);
12 daphnia were used for each test concentration (in
guideline are suggested: 40)
