Концепція вибору доцільності проведення імовірнісної оцінки екологічного ризику

Abstract

When determining the risk of an environmental hazard (determining the HQ hazard ratio), conservative values ​​are usually used: when determining exposure, the maximum is maximally reasonable (90, 95 percent of the distribution) for rare or endangered species and the average dose or stressor concentration for normally functioning species. When determining the response, the value of the largest dose (concentration) is selected as the reference value of toxicity (TRV), which does not result in the appearance of statistically or biologically significant adverse effects (NOAEL) for the first category of species and the value of the minimum dose (concentration) detected by the trial, which leads to the appearance of statistically or biologically significant adverse effects (LOAEL) for the second.
