OECD SIDS o-<strong>TOLUIDINE</strong><br />
4. ECOTOXICITY ID: <strong>95</strong>-<strong>53</strong>-4<br />
DATE: 07.01.2005<br />
greater than 250 mg/l.<br />
- 2/3 (approx. 67 %) of the animals died after 96 h at 250 mg/l.<br />
- Concentrations of o-toluidine at or below 100 mg/l did not appear to affect<br />
the bivalves adversely.<br />
Test condition : - A serie of 3 l glass aquaria, each containing 2 l of synthetic seawater and<br />
3 bivalves was dosed at 0, 100, 250, 500, and 1500 mg/l o-toluidine.<br />
- o-Toluidine was added to water in 1 ml of methanol carrier.<br />
- Aquaria were aerated and held in a water bath (15 +/- 1 °C) for 96 h.<br />
- Synthetic seawater solutions were exchanged daily, and mortalities were<br />
removed and recorded every 12 h.<br />
Reliability : (2) valid with restrictions<br />
