Below is Hazard according to data from the assessment report for Jylamvo (metotrexat) 26 January 2017, EMA/78284/2017.

Persistence: "EPI* (EPA) – BIOWIN v4.10: Not readily biodegradable", i.e. P. EPI (Estimation Program Interface) BIOWIN is a computer program for QSAR calculations (Quantitative Structure Activity Relationship: quantitative mathematical connection between the chemical structure/physicochemical properties of the various substances and their biological and chemical activities).

Bioaccumulation: BCF = 3.162 L/Kg wet-wt. Conclusion B (N).

Acute toxicity: There are EC50 values ​​for algae and crustaceans, lowest for algae 10 mg/L. Since data is missing for one trophic levels, the conversion factor 2 is used and results in the score 2 *, i.e. 2 uncertain.
