. Ship emissions in ports can have a significant impact onlocal air quality (AQ), population exposure and therefore human health inharbour cities. We determined the impact of shipping emissions in harbourson local AQ and population exposure in the Baltic Sea harbour cities Rostock(Germany), Riga (Latvia) and the urban agglomeration of Gdansk–Gdynia(Poland) for 2012. An urban AQ study was performed using a global-to-localchemistry transport model chain with the EPISODE-CityChem model for theurban scale. We simulated NO2 , O3 and PM concentrations in 2012with the aim of determining the impact of local shipping activities onpopulation exposure in Baltic Sea harbour cities. Based on simulatedconcentrations, dynamic population exposure to outdoor NO2 concentrations for all urban domains was calculated. We developed and used anovel generic approach to model dynamic population activity in differentmicroenvironments based on publicly available data. The results of the newapproach are hourly microenvironment-specific population grids with aspatial resolution of 100 m  ×  100 m. We multipliedthese grids with surface pollutant concentration fields of the sameresolution to calculate total population exposure. We found that the localshipping impact on NO2 concentrations is significant, contributing22 %, 11 % and 16 % to the total annually averaged grid meanconcentration for Rostock, Riga and Gdansk–Gdynia, respectively. ForPM 2.5 , the contribution of shipping is substantially lower, at1 %–3 %. When it comes to microenvironment-specific exposure to annual NO2 , the highest exposure to NO2 from all emission sources wasfound in the home environment (54 %–59 %). Emissions from shipping have ahigh impact on NO2 exposure in the port area (50 %–80 %), while theinfluence in home, work and other environments is lower on average(3 %–14 %) but still has high impacts close to the port areas and downwindof them. Besides this, the newly developed generic approach allows fordynamic population-weighted outdoor exposure calculations in European citieswithout the necessity of individually measured data or large-scale surveyson population data.
