Air Quality and Morbidity: Concentration-response Relationships for Sweden

Abstract: The study investigates the morbidity impacts of air
pollution when pollution may affect both the likelihood and duration of
respiratory problems. The relationship between comparatively low pollutant
levels and respiratory ailments is estimated using Swedish data, and the
change in respiratory-related restricted activity days (RRAD) due to a unit
change in NO2 is calculated. The analysis pays particular attention to
overdispersion, the high proportion of zero values and the peak in the RRAD
distribution, problems that have not been addressed thoroughly in previous
studies. Our results suggest that it is a challenging task to set air
quality standards for environments where modes increases in pollutant
concentrations may significantly prolong respiratory health problems for
the most vulnerable individuals.
