8.4.3. NOAEL and NOAEC

xIn individual laboratory assays, The NOAEL and NOAEC are the highest dose (in acute toxicity tests) and concentration (in chronic toxicity tests), respectively, which do not induce mortality significantly higher than that observed in controls. The statistical comparison between uncorrected mortality in the treated sample and in the control is performed using the Chi2 test. The highest dose/concentration where bee mortality is not significantly different (p = 0.05) from the control is considered as NOAEL/NOAEC (respectively).
