DEBtox parameter values for model fits for the effects of seven chemicals on survival over time for Apis mellifera spp. blank killing rate is measure of the rate of background mortality in a population not subject to exposure; the No Effect Concentration (NEC) is a time-independent toxicological threshold below which no effects occur even over infinite exposure time; the elimination rate is a rate parameter determining when the equilibrium between internal and external concentration is reached in time; the killing rate is the toxic potency of the compound (once the NEC is exceeded) expressed in relation to the environmental concentration and time.
