The relationship between reduction in mortality and changes in pollutant species following air quality interventions

摘要

The large weight of evidence on associations between air pollutants and health outcomes provides substantive support for causal relationships. However work on the establishment of causal pathways from air quality interventions is scarce.The gradual and stepwise introduction of regulations for abatement of pollution may not be associated with readily definable turning points in pollutant trends or levels; clearly separable from other environmental or lifestyle changes, or easily linked and analyzed with trends in important health outcomes such as hospital admissions or mortality.
