Calculation and justification of transfer parameters for the uptake of stable isotopes in food - FS21110

Description
The NRPB foodchain model FARMLAND will be used to calculate the concentrations of various elements in foods for a continuous deposition onto ground. The following elements will be considered: lead, cadmium, nickel, arsenic, mercury, copper and chromium. The foods to be considered will be as follows: milk, beef, lamb, offal, green vegetables, root crops and cereals. A critical evaluation and justification of the transfer factors used in the models will also be included.
Objective
To provide more detailed information relating to the assessment of the intake od certain toxic elements from the food chain. The provision of additional data on concentrations in food, to supplement those provided in NRPB-M527 (output from project FS2157), will lead to a clearer picture of the accumulation over time of anthropogenic elements in environmental compartments that impact the food chain. Such information will allow a more rigorous and detailed assessment to be made of the releases to the environment from industrial processes subject to Integrated Pollution Control.
