The T-value in the score for hazard refers to chronic toxicity.
Assessment report for Anoro (umeclidinium bromide/vilanterol) and vilanterol 28 March 2014, EMA/CHMP/163509/2014.
Persistence: No data.
Bioaccumulation: log Kow 0.092 (to pH 5), 1.354 (to pH 7), 1.390 (to pH 9). Conclusion: not B.
Chronic toxicity: There is NOEC for 3 trophic levels, lowest NOEC for algae 95.4 microg/L.
The risk, PEC/PNEC, calculated from data in the assessment report from a European perspective:
PEC = 0.000 13 microg/L
PNEC = Lowest NOEC, 95.4 microg/L/10 (Assessment Factor (AF) for 3 chronic studies) = 9.54 microg/L
PEC/PNEC = 0.000 0136, i.e. insignificant.
Fass environmental information for Relvar Ellipta (fluticasone furoate, vilanterol) and vilanterol (downloaded 2018-06-14).
Persistence: It can not be excluded that vilanterol is persistent, as data is missing.
Bioaccumulation: Log Pow = 1.26
Chronic toxicity: There is NOEC for 3 trophic levels, lowest NOEC for algae 62.50 microg/L
PEC/PNEC is based on estimated sales in Sweden in 2020. PEC/PNEC = 2.40 x 10-5, i.e. insignificant.
