OECD SIDS o-<strong>TOLUIDINE</strong><br />
4. ECOTOXICITY ID: <strong>95</strong>-<strong>53</strong>-4<br />
DATE: 07.01.2005<br />
118<br />
suspension was measured for each concentration of the test and control<br />
preparations.<br />
Remark : Microcystis aeruginosa is a blue-green algae (Cyanobacteria).<br />
Result : Reported TT (toxicity threshold) refers to nominal concentration and was<br />
determined at 3 % effect compared to the control (comparable to EC3)<br />
Test condition : - Test under static conditions<br />
- Nominal concentrations are given<br />
- Test temperature= 27 °C<br />
- Algal were submitted to continuous artificial light<br />
- pH=7<br />
- Turbidity of the solutions was measured.<br />
Reliability : (2) valid with restrictions<br />
Test procedure in accordance with generally accepted scientific standards<br />
and described in sufficient detail<br />
Flag : Critical study for SIDS endpoint<br />
13.07.2004 (109) (110)<br />
Species : Scenedesmus quadricauda (Algae)<br />
Endpoint : biomass<br />
Exposure period : 96 hour(s)<br />
Unit : mg/l<br />
EC3 : = 10<br />
Limit test :<br />
Analytical monitoring : no data<br />
Method : other: Cell multiplication inhibition test<br />
Year : 1<strong>95</strong>9<br />
GLP : no<br />
Test substance : other TS: o-Toluidine, purity is not specified<br />
Remark : Reported TT (toxicity threshold) refers to nominal concentration and is<br />
comparable to EC3<br />
Test condition : - The strain cultures were previously mixed with the following salts: 570<br />
mg/l KNO3, 200 mg/l CaSO4, 140 mg/l KH2PO4, 90 mg/lMgSO4, 3 mg/l<br />
FeCl3 and kept at day light and 24 °C. The culture medium was renewed<br />
every 2 months.<br />
Before the inoculation in the test system the strain culture is passed<br />
through a mebrane filter and then mixed with distilled water and again<br />
filtered.<br />
- Temperature= 24 °C<br />
- Continuous illumination<br />
Reliability : (2) valid with restrictions<br />
Basic data given<br />
18.06.2004 (105)<br />
Species : Scenedesmus quadricauda (Algae)<br />
Endpoint : biomass<br />
Exposure period : 8 day(s)<br />
Unit : mg/l<br />
EC3 : 6.3<br />
Limit test :<br />
Analytical monitoring : no data<br />
Method : other: cell multiplication inhibition test<br />
Year : 1977<br />
GLP : no<br />
Test substance : other TS: o-Toluidine, purity is not specified<br />
Method : Cell multiplication inhibition test according to Bringmann<br />
and Kuehn (1977)<br />
Remark : It is unclear whether the algae are within the exponential growth throughout<br />
the whole exposure period of 8 days.<br />
Result : Reported TT (Toxicity threshold) is comparable to EC3; value refers to<br />
