WebMar 1, 2024 · In the present study, only the ingestion route (Equation (4)) was considered for the determination of chronic daily intake. (4) C D I F − = F c o n c × I R × E F × E D × C F B W × A T where, CDI F-is the chronic daily intake of F − in mg kg −1 day −1 and F c o n c is the concentration of fluoride in μg/mL. WebI understand that the chronic daily intake equation is CDI = [ (Concentration) (Ingestion Rate) (Exposure Frequency) (Exposure Duration)]/ [ (Body Weight) (Averaging Time)] The ingestion rate is 2.3 L/day. That wasn't given in the question, and the standard …
WebThe CSF is also called a "potency factor" and is used to calculate the Incremental Lifetime Cancer Risk by multiplying the CSF by the chronic daily intake (CDI).
