Ttc threshold
WebOct 15, 2024 · Moreover, TTC is not an absolute threshold and thus some low level of cancer risk, e.g., 10 −5 or 10 −6, exists, even below TTC. This is in contrast to the indication of an absolute threshold below which there is no risk on human health . WebAbstract. To derive an acute TTC threshold, the correlation between Allowable Daily Intakes (ADIs, chronic values) and Acute Reference Doses (ARfDs) of pesticides evaluated in the EU was investigated and their distributions were compared. The correlation between ARfDs and ADIs was significant (p = 0.01), but weak (r (2) = 0.051).
