A simple model to predict accumulation of PCDD/Fs in an agricultural food chain

The accumulation of PCDD/Fs in the air-soil/feed-cattle-beef/milk agricultural food chain is described. A simple model describing the accumulation through the food chain is presented. The model is employed to predict the concentrations of PCDD/Fs in milk and beef in Germany and found to be in very good agreement with measured concentrations from monitoring studies.
