Exposure to environmental chemicals relevant for respiratory hypersensitivity: European aspects
B Sivertsen, J Clench-Aas - Toxicology letters, 1996 - Elsevier
The need for assessing air pollution exposure on the individual and population levels is
urgent, as health effects are observed at concentrations even below existing air quality
guidelines (AQG). Typical European concentrations and trends over time of four main air
quality indicators (nitrogen dioxide, sulphur dioxide, ozone and particulate matter) are
presented, together with their revised WHO AQG. In order to describe concentrations of
pollutants each individual and population groups are exposed to, methods have been …
