What Does HEC Stand For?

HEC stands for Human Equivalent Concentration

HEC, or Human Equivalent Concentration, is a scientific metric used to assess the equivalent exposure levels of chemicals or pollutants that would have comparable biological effects on humans as observed in specific test subjects, typically animals. This measurement is crucial for risk assessment and regulatory purposes, ensuring that safety standards for human health are adequately evaluated based on experimental data.
