Introduction of EnVIE concept and overview of EnVIE project

European citizens want to live longer, healthier, in an environment of low involuntaryrisks, and at an affordable cost. Urban environmental policies should, therefore,manage the determinants of health as far upstream as possible and improve thecitizens quality of life. People are exposed to a multitude of chemical, physical andbiological stressors in their environment, some of which are apparently harmless,others of low health significance and some incur significant risks to health, at least forvulnerable individuals. Human exposure to environmental contaminants occurs viavarious pathways (air, water, food...) and routes of entry (inhalation, ingestion anddermal). Exposure via air occurs outdoors and in different indoor ?environments; e.g.home, workplace, transit. Indoor air pollution from different sources may cause oraggravate illnesses, increase mortality, and have major economic and social impacts.Knowing the relative contributions of these ?environments to exposure and healtheffects is essential for effective risk management and resources allocation.
