OECD SIDS o-TOLUIDINE
4. ECOTOXICITY ID: 95-53-4
DATE: 07.01.2005
114
Type : static
Species : Daphnia sp. (Crustacea)
Exposure period : 48 hour(s)
Unit : mg/l
EC50 : 250 measured/nominal
Analytical monitoring : no data
Method : other: not specified
Year : 1985
GLP : no data
Test substance : other TS: o-Toluidine, purity is not specified
Result : - Total mortality was observed within 72 h at o-toluidine concentrations
greater than 250 mg/l.
- 2/3 (approx. 67 %) of the animals died after 96 h at 250 mg/l.
- Concentrations of o-toluidine at or below 100 mg/l did not appear to affect
the bivalves adversely.
Test condition : - A serie of 3 l glass aquaria, each containing 2 l of synthetic seawater and
3 bivalves was dosed at 0, 100, 250, 500, and 1500 mg/l o-toluidine.
- o-Toluidine was added to water in 1 ml of methanol carrier.
- Aquaria were aerated and held in a water bath (15 +/- 1 °C) for 96 h.
- Synthetic seawater solutions were exchanged daily, and mortalities were
removed and recorded every 12 h.
Reliability : (2) valid with restrictions
