it is used in the calculation of risk assessment for carcinogens.
LADD = (Cw x IR x EF x ED)/ (Bw x AT)
Cw = Concentration
IR = Ingestion (eg) ratio
EF=Exposure Frequency
ED=Exposure Duration
BW=Body Weight
AT=Average time ( for carcinogens = life time (70 years eg) x 365 days
Can i have the related paper on this calculation Sepehr Maleki
Thanks
