We present a study of the potential export pathways of middle-lived pollutants from the Iberian Peninsula using
an advanced 3-D Lagrangian atmospheric transport model (FLEXPART). A period of five years, from 2000 to 2004, was
analyzed. Results confirm that the Mediterranean Sea and Central Asia are the dominant sinks of the air originated in the
Iberian Peninsula in the range of 3 to 10 days of transport. The study is important, both in scientific terms and in the
preparation of useful information for decision-making.
