The T-value in the score for hazard refers to chronic toxicity. Underlying data for P, B, T and risk are from Fass.
Fass environmental information for Selsun (selenium sulfide) (downloaded 2018-08-20).
Persistence: No data.
Bioaccumulation: Log Pow = 0.91 at neutral pH.
Chronic toxicity: There is NOEC for 3 trophic levels, lowest NOEC for algae (Pseudokirchnerella subcapitata) 0.547 microg/L.
PEC/PNEC is based on sales data in Sweden in year 2016. PEC/PNEC = 1.26 which gives the risk moderate.
