1G - Long-range transport of pollutants (chemicals) (WEP/10) Long Range Transport and Human Intake Fraction Modelling: Insights for Europe. Pennington, David1, Ammann, Christoph1, Pelichet, Thierry1, Margni, Manuele1, Jolliet, Olivier1, 1 EPFL, Lausanne, Switzerland, Switzerland ABSTRACT- This poster illustrates the link between the long range transport of a chemical and human intake fractions using a spatial multimedia chemical fate and human exposure model (IMPACT 2002). The importance of factors such as food production levels, water supply quantities, and population density relative to the location of an emission are taken into account. A chemical's ability to be transported over long distances is quantified in terms of the fraction lost via advection at two scales - from the local region of an emission and from a defined Europe region. The intake fraction is the fraction of mass of a chemical released into the environment that is taken in by a population (via ingestion, inhalation, and dermal absorption). A distinction is made between local, European, and Global contributions to intake fractions as a function of chemical properties and emission locations within Europe. Key words: intake fraction, spatial multimedia model, long range transport |
