With high probability acutely not harmful to algae.
The assessment of the algal toxicity is based on effect data taken from the “Commission for the Evaluation of Substances Hazardous to Waters” (KBWS) data sheet no. 1385, which is part of the German Federal Water Act (Article 19g). Based on the collected data a substance is classified according to its water-hazardous properties (WGK 1 to 3). 2,2 -phenyliminodiethanol was classified as WGK 2, which indicates a hazard to waters. As the list with the classified substances was published in the Bundesanzeiger (Federal Ministry of Justice, 2005. Bundesanzeiger No. 142 a),
The KBWS contains an abstract on the algae test according to DIN EN 28692 (= ISO 8692). The test species was Desmodesmus subspicatus. Test item concentrations were not analytically verified, but can be assumed to be stable based on the analytical results from an acute toxicity study to daphnids (BASF AG, 1998). The 72 -h ErC50 was determined to be 418 mg/L based on growth rate (72 -h EbC50 = 393 mg/L). The EC10 was only determined for biomass (72 -h EbC10 = 172 mg/L; KBWS, 1995). As the endpoint biomass is generally somewhat lower than the growth rate and can therefore be considered as a conservative value.
Based on the available data, 2,2 -phenyliminodiethanol is assessed to be not acutely harmful to algae with high probability. Chronic effects are not expected as well.
