Abstract [en]

TAB3-PD-12

Whether coarse particles dominating road dust influence health or not is a question in the matter of measures of priority (remedial measures), among others. Within this project, we investigated how particulate matter (PM10), when characterized by high levels of road dust, affects daily mortality, acute hospital admissions, and emergency department visits in greater Stockholm.

The study covered the period of 1994 to 2002. Daily hospital admissions and deaths were collected from registers maintained by the Centre for Epidemiology at the National Board of Health and Welfare. Records of acute visits at hospitals for asthma were obtained from Stockholm County Council. A total of 457 days characterized by high levels of road dust were identified using the 85th percentile for local non-exhaust PM10 time-series adjusted for rural background PM10 and urban levels of NOx representing local exhaust emissions. Data were analyzed and modelled with additative Poisson regression, following the strategy used in the APHEA project. In other words, smoothed functions for potential nonlinear relations with confounders are used in conjunction with linear terms, in order to achieve parameter estimates for the short-term effect of pollutants.

The estimated effect of PM10 on asthma visits was 3.4% per 10 μg/m3for road dust days.

With a 10.2 μg/m3 higher average urban background level of PM10(compared with days not classifed as road dust days), a mean of 20.5 daily respiratory admissions and a estimated coefficient of 0.0021 (0.00165), expressing a relative change of 2.1% per 10 μg/m3 PM10,roughly 200 respiratory hospital admissions were attributed to the road dust PM10 during the study period. There was no evidence that road dust affects hospital admissions for cardiovascular diseases. This might indicate that smaller, combustion-related particles are behind the connection betwen PM10 and acute cases of cardiac admissions that has been found even in Stockholm.

The results of this study, as well as the epidemiologic litterature about mineral particles and the coarse fractions, gives evidence for road dust to increase respiratory problems and the acute visits, as well as hospital admissions for the matter.
