basis of climatic and lifestyle considerations. These data are used by the Risk Analysis Group--Quebec's
Ministry of Environment and Wildlife.
2.1 Human Daily Intake of Contaminants from Produce
Intake resulting from contaminated produce (i.e. vegetables only) can be defined as:
where:
I p = (P h × P c × B v × PSQG HH ) + (P l × P c × P r ) [3]
BW
I p
P h
P c
B v
PSQG HH
= total intake of contaminants from produce (mg/kg⋅day)
= percent produce homegrown
= produce consumption rate (kg/day)
= biotransfer factor for produce
= preliminary human health-based soil quality guideline (mg/kg)
