An assessment of the risks associated with PCDDs and PCDFs following in the application of sewage sludge to agricultural land in the UK.
A model has been developed to describe the transfer of PCDDs and PCDFs from sludge-amended soils to the human foodchain.
The model is conservative and assumes that all foods consumed by an individual are derived from sludge-amended soils.
Predicted concentrations of PCDDs and PCDFs in potatoes, cereals, root vegetables and leafy vegetables were in close agreement with mean concentrations reported in the food survey conducted by MAFF in the UK.
Predicted concentrations in milk were below the Maximum Tolerable Concentration adopted by MAFF.
