Benzo[a]pyrene Toxic Equivalent Calculator Convert the measured concentration of a polycyclic aromatic hydrocarbon (PAH) into its benzo[a]pyrene toxic equivalent (BaP-TEQ) using a toxic equivalency factor (TEF). Benzo[a]pyrene is the reference carcinogen — free online calculator.

Formula

BaP-TEQ = Concentration × TEF
  • Benzo[a]pyrene Toxic Equivalent Calculator calculates its result from PAH Concentration (ng/m³), Toxic Equivalency Factor (TEF). It uses the formula BaP-TEQ = Concentration × TEF. Change any input to recalculate the result instantly.
  • The main inputs are PAH Concentration, Toxic Equivalency Factor. Enter them in the units and format shown in the calculator.
  • Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Benzo[a]pyrene Toxic Equivalent

Inputs
  • PAH Concentration: 5 ng/m³
  • Toxic Equivalency Factor: 1 TEF

Using PAH Concentration (ng/m³) = 5, Toxic Equivalency Factor (TEF) = 1, the calculated result is 5.
