Additional information

The acute toxicity of Biofert Plusz towards Danio rerio was investigated in a study conducted according to OECD Guideline 203 (Fish, Acute Toxicity Test) under semi-static conditions. Fish were exposed for 96 h to measured Biofert Plusz concentrations ranging from 222 to 3861 mg fresh weight/L, equivalent to 62.3 -1085 mg dry matter/L. Analytical monitoring of test material concentration was performed by HPLC and quantification of the main component (L-Threonine). The 96 h LC50 was determined to be 738 mg dry matter/L (effective).
