m-Cresol - ipcs inchem

OECD SIDS
m- / p-CRESOL MIXTURE
4. ECOTOXICITY ID: 15831-10-4
DATE: 24.05.2004
Species : Chlorella pyrenoidosa (Algae)
Endpoint : other: chlorophyll content
Exposure period : 72 hour(s)
Unit : mg/l
EC0 : > 50
EC50 : 127
EC100 : 250
Limit test :
Analytical monitoring : no
Method :
Year : 1968
GLP : no
Test substance : other TS: m-cresol, no purity reported
Result : 1000 mg/l: complete destruction of chlorophyll
EC50 was not reported in the study, but it can be taken from the graph
Test condition : TEST ORGANISMS
- Strain: Emerson strain
- Test temperature: 25 +- 1 degrees C
- pH: 7.0
- Photoperiod: continuous illumination
TEST PARAMETER: chlorophyll
Reliability : (2) valid with restrictions
Test procedure comparable to standard method and in
accordance with generally accepted scientific standards;
sufficient documentation

Species : Microcystis aeruginosa (Algae, blue, cyanobacteria)
Endpoint : other: cell multiplication
Exposure period : 8 day(s)
Unit : mg/l
TGK : 13
Limit test :
Analytical monitoring : no
Method : other: Modified DEV L9 (cell multiplication inhibition test)
Year : 1975
GLP : no
Test substance : other TS: m-cresol, no purity reported
Remark : TGK = Toxicity treshold, determined at 1% effect compared to
control
Reliability : (3) invalid
It is unclear whether the algae are within the exponential
growth throughout the whole exposure period of 8 days.
