3. Evaluate exposure

The aim of this stage is to quantify the exposure of target populations to the selected substances. Quantification is carried out by determining :

• population exposure concentrations as a function of environmental concentrations, exposure rate and individual body weight;

• quantities administered via pre-defined transfer channels.

Exposure is quantified on the basis of measurement results, transposed data and estimates obtained by modeling pollutant transfer phenomena from the source to the exposed population.

The exposure assessment will cover :

• a definition of exposure scenarios;

• estimated exposure concentrations;

• determination of...
