Description of key information

Short-term effects on fish (OECD 203)

The toxic effect of the test item Magnesium glycerophosphate to Zebrafish (Danio rerio) was assessed in a semi-static limit test. Based on the test results the 96-hour LC50 was determined to be >100 mg test item/L based on nominal concentrations. The NOEC was determined to be ≥ 100 mg test item/L also based on nominal concentrations. The initial concentrations and the maintenance of the exposure concentrations during the test were verified in the analytical part. All reported results refer to nominal values since the concentrations of the test item were within ± 20 % of the nominal concentrations during the test.

 

Short-term effects on aquatic invertebrates (OECD 202)

The toxic effect of the test item Magnesium glycerophosphate to Daphnia magna was assessed in a static limit test. The 48-hour NOEC was determined to be ≥100 mg test item/L. The 48-hour LOEC was determined to be >100 mg test item/L and the 48-hour EC50 value was determined to be >100 mg test item/L. The initial concentration and the maintenance of the exposure concentration during the test were verified in the analytical part. All reported results refer to nominal values since the concentration of the test item were within ± 20% of the nominal concentration during the test.

 

Effects on algae and aquatic plants (OECD 201)

The influence of Magnesium glycerophosphate on the growth of the freshwater green algae Pseudokirchneriella subcapitata was assessed in a static concentration-response limit test. The 72-hour EyC50 was calculated to be >100 mg test item/L and the 72-hour ErC50 value was calculated to be >100 mg test item/L. The 72-hour NOEyC was determined to be ≥100 mg test item/L and the associated 72-hour LOEyC was >100 mg test item/L. The 72-hour NOErC was determined to be ≥100 mg test item/L and the associated 72-hour LOErC was >100 mg test item/L. The initial concentrations and the maintenance of the exposure concentrations during the test were verified in the analytical part. All reported results refer to nominal values since the concentrations of the test item were within ± 20% of the nominal concentrations during the test.

 

Effects on micro-organisms (OECD 209)

At a nominal test concentration of 1000 mg test item/L less than 10% inhibition was observed after three hours of incubation. The mean respiration rate was 6.5% at three replicates of 1000 mg Magnesium glycerophosphate/L. The respiration rate of the activated sludge to Magnesium glycerophosphate at the rate of 1000 mg/L did not show substantial biological effects. Magnesium glycerophosphate at the rate of 1000 mg/L had no toxic effects on respiration activity of activated sludge. Therefore it can be assumed that the NOEC is above 1000 mg/L.
