What Does PNEC Stand For?

PNEC stands for Predicted No Effect Concentration

PNEC, or Predicted No Effect Concentration, refers to the estimated concentration of a substance in the environment below which adverse effects on ecological systems are not expected to occur. It is a critical value used in environmental risk assessments to evaluate the safety and impact of chemicals, ensuring that their presence in ecosystems remains within safe limits. PNEC is determined through the analysis of toxicological data and environmental exposure levels, serving as a guideline for regulatory compliance and environmental protection.
