英文摘要 | Air pollution concentrations have been decreasing in many cities in the developed countries. We have estimated time trends and health effects associated with exposure to NOx, NO2, O-3, and PM10 (particulate matter) in the Swedish cities Stockholm, Gothenburg, and Malmo from the 1990s to 2015. Trend analyses of concentrations have been performed by using the Mann-Kendall test and the Theil-Sen method. Measured concentrations are from central monitoring stations representing urban background levels, and they are assumed to indicate changes in long-term exposure to the population. However, corrections for population exposure have been performed for NOx, O-3, and PM10 in Stockholm, and for NOx in Gothenburg. For NOx and PM10, the concentrations at the central monitoring stations are shown to overestimate exposure when compared to dispersion model calculations of spatially resolved, population-weighted exposure concentrations, while the reverse applies to O-3. The trends are very different for the pollutants that are studied; NOx and NO2 have been decreasing in all cities, O-3 exhibits an increasing trend in all cities, and for PM10, there is a slowly decreasing trend in Stockholm, a slowly increasing trend in Gothenburg, and no significant trend in Malmo. Trends associated with NOx and NO2 are mainly attributed to local emis-sion reductions from traffic. Long-range transport and local emissions from road traffic (non-exhaust PM emissions) and residential wood combustion are the main sources of PM10. For O-3, the trends are affected by long-range transport, and there is a net removal of O-3 in the cities. The increasing trends are attributed to decreased net removal, as NOx emissions have been reduced. Health effects in terms of changes in life expectancy are calculated based on the trends in exposure to NOx, NO2, O-3, and PM10 and the relative risks associated with exposure to these pollutants. The decreased levels of NO x are estimated to increase the life expectancy by up to 11 months for Stockholm and 12 months for Gothenburg. This corresponds to up to one-fifth of the total increase in life expectancy (5470 months) in the cities during the period of 1990-2015. Since the increased concentrations in O-3 have a relatively small impact on the changes in life expectancy, the overall net effect is increased life expectancies in the cities that have been studied. |
