An ASRI study was conducted on the test material, this study was conducted according to OECD guideline 209. The results of this study showed Sodium Glucoheptonate to have an EC50 value of 1000 mg/L and a NOEC of 1000 mg/L.
A study was performed to assess the effect of the test item on the
respiration of activated sewage sludge. The method
followed was designed to be compatible with the OECD Guidelines for
Testing of Chemicals (2010) No. 209 "Activated Sludge, Respiration
Inhibition Test (Carbon and Ammonium Oxidation) ".
Activated sewage sludge was exposed to an aqueous dispersion of the test
item at concentrations of 10, 100 and 1000 mg active ingredient (ai)/L
(3 replicates of the 1000 mg ai/L test concentration) for a period of
3 hours at a temperature of 20 ± 2°C with
the addition of a synthetic sewage as a respiratory substrate.
The rate of respiration was determined after 3 hours contact time and
compared to data for the control and a reference item,
The effect of the test item on the respiration of activated sewage
sludge gave a 3‑Hour EC50value of greater than 1000 mg
ai/L. The No Observed Effect Concentration (NOEC)
after 3 hours exposure was1000
It was considered unnecessary and unrealistic to test at concentrations
in excess of 1000 mg ai/L.
The reference item gave a 3-Hour EC50value of 12 mg/L, 95%
confidence limits 9.6 - 15 mg/L.
