Hazard 4 P 3 B 0 T 1 Risk Insignificant


The T-value in the score for hazard refers to acute toxicity. Underlying data for P, B, T and risk comes from Fass.se.

Fass environmental information

Fass environmental information for formoterol and Duaklir Genuair (aclidinium, formoterol) (downloaded 2018-07-04).


Persistence: "Formoterol fumarate dihydrate is not readily biodegradable (loss of Dissolved Organic Carbon (DOC) < 70% after 28 days) (method: ISO 7827-1984 (E)). Based on the data above (considering that no other data is available), the statement “Formoterol fumarate dihydrate is potentially persistent” has been assigned."

Bioaccumulation: Log D = 0.41 at pH 7.4.

Acute toxicity: There are data for 3 trophic levels, lowest for algae 94 mg/L.


PEC/PNEC is based on sales data in Sweden in year 2014. PEC/PNEC = 0,0000019 which gives the risk insignificant.
