<strong>DISODIUM</strong> <strong>SUCCINATE</strong><br />
4. ECOTOXICITY ID <strong>150</strong>-<strong>90</strong>-3<br />
DATE: 27.01.2003<br />
j) Water Temperature: 24+/-1ºC<br />
k) Light Condition: 16:8 hours, light-darkness cycle<br />
l) Feeding: None<br />
m) Aeration : Test solution was not aerated during the test period.<br />
-Analytical Procedure: The tested concentrations were measured at the<br />
start and the end of the test period using HPLC.<br />
-Statistical Method:<br />
a) Data Analysis: During test period the test organisms were lived more<br />
than 50% in all concentrations, therefore the LC50 is more than the highest<br />
concentration.<br />
b) Method of Calculating Mean Measured Concentrations (i.e. arithmetic<br />
mean, geometric mean, etc.): Arithmetic mean<br />
Remark : The acute toxicity to fish was calculated based on measured concentration<br />
of butanedioic acid, disodium salt (anhydride), but this chemical is stable as<br />
hexahydrate, i.e., disodium succinate hexahydrate. Then, the test was<br />
carried out with disodium succinate hexahydrate.<br />
Result : - Measured Concentrations: The test concentrations were measured at 0 h<br />
and 96 h. For all of them, the deviations from the nominal were less than<br />
+/- 20%.<br />
