Epub Aug 6. In particular, several studies highlight that higher temperatures enhance rates of peroxyacetylnitrate PAN decomposition [ 323334 ] leading to local NO2 and O3 increases in polluted emission regions. For nine cities in France where the impacts of the heatwave were largestFilleul et al.
There is now strengthened evidence for effects of long-term exposure to O3 on respiratory and cardiorespiratory mortality in warm season months [ 1 ], although taken as a whole this evidence is limited at present, as it is primarily derived from studies in North America [ 3 ].
Air-quality-related health impacts from climate change and from adaptation of cooling demand for buildings in the eastern United States: An interdisciplinary modeling study.
Modeling and observational analyses suggest a warming climate degrades air quality increasing surface O 3 and particulate matter in many populated regions, including during pollution episodes.
Climate change will also affect climate extreme events such as heatwaves. Whilst evidence has also strengthened for independent impacts of both short-term and long-term exposure to NO2 on mortality, hospital admissions and respiratory symptoms, because of strong correlations between NO2 and other air pollutants it remains difficult to discern a direct effect [ 1 ].
This review examines the current evidence for the effects of climate change on ambient air quality and on the consequent health impacts over Europe. We find that by mid-century, climate change alone can increase fine particulate matter PM2.
