Additional information
The toxicity of Formaldehyde, polymer with benzenamine, hydrogenated to Daphnia magna was determined according to OECD Test Guideline 202. Tested concentrations were 1, 2, 4, 8, 16, 32, 64 and 128 mg/l. Analytical monitoring was done using TOC determination. Potassium dichromate was used as positive control substance. The EC50 values after 24 h and 48 h were calculated utilizing the Trimmed Spearman-Kabler method (v. 1.5) with 95% confidence interval. The EC50 (48 h) concentration determined is 15.4 mg/l.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
