1. Introduction. Human exposure to aient levels of air pollution is a risk to public health (Brunekreef and Holgate, 2002; Pope and Dockery, 2006; WHO, 2006).It has been estimated that, in Europe, exposure to outdoor and traffic-related air pollution has greater adverse effects on public health in the long term, versus the short term (Künzli et al., 2000).
