Abstract/Summary

It is necessary to assess the contamination of animal products by pollutants in order to protect human health. This can be achieved by understanding the processes whereby contaminants are introduced into the food chain. Such contamination can arise from the atmospheric deposition on to crops and soil or via contaminated feed. These processes are described and quantified with particular reference to the deposition of organic pollutants onto pasture. The transfer of the contaminants from the fodder and feed to the animal is also described. Finally, these processes are put in context by the illustration of how they are used in regulatory exposure models.
