The main purpose of the risk assessment is to assess the future risk from cadmium in mineral P-fertilisers to human health, soils and waters using model calculations. The risk assessment of Cd in mineral fertilisers has been performed according to procedures suggested by ERM (2000). The procedure consists of three modules: 1) The accumulation module; 2) The exposure module; 3) The risk characterisation module. Two scenarios for Cd in mineral P-fertilisers were used: 2.3 mg Cd kg-1 P2O5-(present level of Cd ) and 60 mg Cd kg-1 P2O5 average EU-level).In the accumulation module the future (in 100 years) concentration of Cd in soils was calculated using a mass balance model. Application of P-fertiliser containing 60 mg Cd kg-1 P2O5 increases the soil concentration of Cd by 16 to nearly 100 percent depending on type of crop and region. In the exposure module, the uptake of Cd from the soil to wheat, potato and carrot is calculated as well as the relative contribution from fertilisers to the human uptake of Cd. The application of P-fertilisers containing 60 mg Cd kg-1 P2O5 in 100 years increase the daily intake of Cd by 7
