4. Ecotoxicity Substance ID: <strong>7447</strong>-<strong>40</strong>-7<br />
4.3 Toxicity to Aquatic Plants e.g. Algae<br />
Species:<br />
Nitzschia linearis (diatom)<br />
Endpoint:<br />
growth rate<br />
Exposure period: 120 hours<br />
Unit: mg/l Analytical monitoring: yes<br />
EC50 = 1337<br />
Method:<br />
other<br />
Year: 1968 GLP: no data<br />
Test substance: as prescribed by 1.1-1.4, purity: A.C.S.-grade<br />
chemicals<br />
Remarks:<br />
Diatoms were cultured in synthetic dilution water<br />
under controlled conditions. Tests were made by<br />
putting standard inoculum of cells in each of the<br />
150 ml Erlenmeyer flasks, and comparing the number<br />
of cells produced at the end of a 5-day period. A<br />
graded series of test concentrations were used.<br />
Reliability: (2) reliable with restrictions<br />

Test substance: not stated<br />
Remark:<br />
German standard methods for the examination of<br />
water, waste water and sludge, bio-assays (group<br />
L); determination of the non-poisonous effect of<br />
waste water to green algae (Scenedesmus chlrophyll<br />
