AB  - Because of its benefits to soil and crops, sewage sludge application on 
      agricultural soils is a managing practice of increasing use. However, this 
      practice may lead to contamination of the food chain, especially by persistent 
      organic pollutants (POPs). The main objective of this study was to integrate 
      probabilistic multimedia models to predict the accumulation of POPs in the food 
      chain and the related risks to humans, as a consequence of sludge application on 
      soil. For that, four models were integrated: (i) soil fate, (ii) plant, (iii) 
      food chain and (iv) exposure and risk. These models were applied for two 
      scenarios (occupational and non-occupationally exposed populations) in a time 
      span of 30 years. The variability of the inputs and outputs was also considered. 
      The model was applied to a case-study of 4 POPs (2,3,7,8TCDD, PCB 180, 
      benzo(a)pyrene, and dibenzo(a,h)anthracene) in an agricultural soil located in 
      Catalonia (NE of Spain). Some differences in cancer risk due to POP exposure were 
      appreciated between both evaluated scenarios. However, all values were below the 
      threshold levels. With the exception of 2,3,7,8TCDD, all the contaminants reached 
      steady state on soil in the first five years of the evaluation. Concentration 
      levels in food (vegetables, meat and milk) were linearly correlated to those in 
      soils. Air inhalation was noted to be an occupational exposure route of minor 
      importance. Sensitivity analysis for 2,3,7,8TCDD showed that exposure parameters 
      were responsible for most of the variability in the results.
