Abstract

&lt;p&gt;Air pollution is repeatedly referred to as the largest environmental health risk in Europe. Exposure to heat can lead to a large variety of negative human health effects. Ground-level ozone (O&lt;sub&gt;3&lt;/sub&gt;), one major air pollutant, often coincides with elevated air temperature levels. There is evidence that the resulting twofold exposure can lead to a human health risk beyond the sum of the individual effects of each health stressor (e.g., Hertig et al. 2020). But previous studies already point to the fact that the observed and modeled linkages between both variables as well as with underlying synoptic and meteorological drivers vary with the location of sites and from one region to another across Europe (e.g., Jahn, Hertig 2020; Jahn, Hertig 2022). Thus, impacts of concurrent elevated levels of O&lt;sub&gt;3&lt;/sub&gt; and air temperate on human health need to be considered with a region-specific perspective. Besides, disease-specific exposure-outcome-relationships have to be taken into account, also with respect to mitigation and adaption strategies in the context of climate change.&lt;/p&gt;&lt;p&gt;The adverse human health effects of ground-level ozone and air temperature under recent and future climate conditions are analyzed and quantified by considering myocardial infarction (MI) as outcome variable. The urban area of Augsburg and two adjacent counties, located in a region with a strong and direct linkage between ozone and air temperature and a sharp projected increase of compound events, represent the regional focus. The association between both exposures and MI risk in Augsburg throughout the 21&lt;sup&gt;st&lt;/sup&gt; century represents the particular focus of this study. The relationship between one health stressor alone and MI was already assessed in previous studies (e.g., Hertig 2020; Chen et al. 2019), but there is only limited evidence about the compound effect of both exposures on MI.&lt;/p&gt;&lt;p&gt;&lt;em&gt;C&lt;/em&gt;&lt;em&gt;hen, K.; Breitner, S.; Wolf, K.; Hampel, R.; Meisinger, C.; et al. &lt;/em&gt;&lt;em&gt;(2019) &lt;/em&gt;&lt;em&gt;Temporal variations in the triggering of myocardial infarction by air temperature in Augsburg, Germany, 1987-2014.
