8 CALIFORNIA PROPOSITION 65: BACKGROUND (CONTINUED) REGULATORY BENCHMARKS -- CARCINOGENS: The NSRL is developed from dose-response modeling of cancer potency. • Results of dose-response modeling can be expressed as the cancer potency factor, also known as the "slope factor” or q₁ in units of risk per mg/kg/day dose. * Alternatively, the dose-response can be expressed as the dose producing a 10-5 risk (i.e., 1 excess lifetime case of cancer per 100,000 exposed persons). This is known as the LED 10-5. Either the q₁* or the LED 10-5 can be used to calculate the NSRL.
