Additional information

Short-term L(E)C50 results are available for each of the three trophic levels.

Fish: Short-term toxicity to Cyprinus carpio was investigated in an OECD TG 203 (Sipos, 2013c). The LC50(96h) was reported to be 84.4 mg/L.

Invertebrates: An acute toxicity test to Daphnia magna was performed (Sipos, 2013d). The EC50(48h) was estimated to be 58.0 mg/L.  

Algae: An OECD TG 201 algal growth inhibition test (Sipos, 2013e) was performed. Exposure of Pseudokirchnerella subcapitata gave an ErC50(72h) value of 61.88 mg/L. The No Observed Effect Concentration was 12 mg/L.

Toxicity to microorganisms:

The toxicity to microorganisms was tested on sewage micro-organisms by measuring the respiration rate under defined conditions in accordance to OECD Guideline 209. The 3h EC50 value was calculated to be 1000 mg/L and the 3h NOEC was assessed to be 1000 mg/L.
