Key value for chemical safety assessment
Additional information
In a 72-hour static test with the green alga Desmodesmus subspicatus (reported as: Scenedesmus subspicatus) according to the German Industrial Standard Test Guideline DIN 38412, the toxicity of 3 -dimethylaminopropionitrile in algae was investigated (BASF, 1989, report no. 01/88/0947 ). After 72 hours an ErC50 of > 500 mg/L and an ErC10 of 30.3 mg/L was estimated for the growth rate, related to the nominal concentration (no analytical verification). Concerning observations of the biomass, the values are: EbC10 (72h): 10.2 mg/L, EbC50 (72h): 209.1 mg/L.
The highest test concentration was perfomed twice, with and without pH neutralization. No difference has been observed between those two treatments.
