MODELING OF HEAVY-METAL TRANSPORT IN FOOD-CHAIN

A mathematical model of contaminant deposition on plant cover and soil surface as well as a description of the transport through the food-ch ain pathway to human consumers is presented. A set of evaluations char acterizing the model applicability and validation was made on two sele cted elements, cadmium and lead: - the share of the human exposure by ingestion to elements dispersed in atmosphere; - the comparison of mod el results with selected hygienic limits as one of possibilities to tr eat the relevance of individual food-chain compartments to the total e xposure.
