The T-value in the score for hazard refers to acute toxicity. Underlying data for P, B, T and risk are from Fass.se.
Fass environmental information for Nicotinell Peppermint (nicotine) (downloaded 2018-07-12).
Persistence: "71% degradation in 28 days (OECD 301B). 72% degradation within 10 day window."
Bioaccumulation: Log Dow = 0.28 at pH 7.4 (OECD 107)
Acute toxicity: There are data for 3 trophic levels, lowest for crustacean (Daphnia pulex) 242 microg/L.
PEC/PNEC is based on sales data in Sweden in year 2016. PEC/PNEC = 0.70 which gives the risk low.
