FHX-CAN (Far-field Human eXposure in Canada) model
FHX-CAN is an evaluative, regional-scale, mass balance model for screening level far-field human exposure assessments in selected regional areas of Canada. The general objective of the FHX-CAN model is to provide information on far-field human exposures to chemicals by linking information on physical-chemical properties and chemical emissions to the environment with simulations for chemical fate in the physical environment (air, water, soil and sediment), food web bioaccumulation (including aquatic and agricultural food chains), and multimedia contact rates (inhalation of outdoor air, ingestion of drinking water and foodstuffs) for seven human age classes in five specific Canadian regions. The model calculates chemical intake rates and intake fractions.
The FHX-CAN model was developed for Health Canada and is based on the FHX model and includes regional environments from the ChemCAN model.
