The T-value in the score for hazard refers to acute toxicity. Underlying data for P, B, T and risk comes from Fass.se, see below.
Alfuzosin has been detected in treated wastewater, surface water and fish in Stockholm County in the last five years (2012-2016).
Fass environmental information for Xatral OD (alfuzosin) (downloaded 2018-07-04).
Persistence: "The potential for persistence of alfuzosin cannot be excluded, due to lack of data."
Bioaccumulation: "log Kow of 1.51 at pH 7.4."
Acute toxicity: There are data for 3 trophic levels, lowest for algae (Pseudokirchnerellia subcapitata) 52 700 microg/L.
PEC/PNEC is based on sales data in Sweden in year 2015. PEC/PNEC = 0.000778 which gives the risk insignificant.
