The following are useful resources for obtaining PNEC values.

1. AMR Industry Alliance Antibiotic Discharge Targets - List of Predicted No-Effect Concentrations (PNECs).
   The PNEC table contains two values, PNEC‐Environment (PNEC‐ENV) values based on eco-toxicology and PNEC‐Minimum Inhibitory Concentration (PNEC‐MIC) values intended to be protective of resistance promotion.
   The AMR Industry Alliance recommendation is that companies target the lower of these two values (when available) for assessing manufacturing site discharges under a risk‐based framework.
