4.2 ACUTE TOXICITY TO AQUATIC INVERTEBRATES<br />
Type : semistatic<br />
Species : Ceriodaphnia sp. (Crustacea)<br />
Exposure period : 48 hour(s)<br />
Unit : mg/l<br />
EC50 : = 200 - 227<br />
Analytical monitoring : no data<br />
Method : other: method developed by NSW Environment Protection Authority (Warne<br />
& Julli, <strong>19</strong>99)<br />
Year : <strong>19</strong>99<br />
GLP : no<br />
Test substance : other TS: sodium carbonate<br />
Method : METHOD FOLLOWED: 48-h immobilisation test using methods developed<br />
by the NSW Environment Protection Authority (Warne and Julli, <strong>19</strong>99).<br />
Immobilisation was defined as the absence of visible movement by the<br />
cladocera within 15 sec of a gentle agitation of the test solution (ASTM,<br />
<strong>19</strong>88). Chemical was tested in a range-finder and definitive test, with a<br />
second definitive test when the results were markedly different.<br />
GLP: No.<br />
STATISTICAL METHODS: Trimmed Spearman-Karber method.<br />
METHOD OF CALCULATION: Toxicity of the chemical was expressed in<br />
three different units, mg/L, mmol/L and toxic units (TU).<br />
ANALYTICAL METHODS: Not reported.<br />
Result : RESULTS: EXPOSED<br />
- Nominal/measured concentrations: Values based on nominal<br />
concentrations.<br />
- Effect data (Immobilisation): 95% confidence limits:<br />
166.9-298.9 mg/l, 156.6-<strong>19</strong>8.3 mg/lg, <strong>19</strong>2.4-267.4 mg/l.<br />
- Concentration / response curve: Not reported.<br />
