Additional information

Toxicity of Zorgol 48 (1-Hexanol, 2-ethyl-, manuf. of, by-products from, distn. Residues) to aquatic algae and cyanobacteria was tested with green alga in a growth inhibition test according to OECD TG 201. Validity criteria according to OECD TG 201 were met. The ErC50 was determined to be 7.6 mg/L. The LOEC and the NOEC were 6.4 and 0.8 mg/L respectively (Muckle/Laus, 2010c).
