This study examines the environmental impacts of urban growth in Warsaw since 2006 and models the implications of future urban development for traffic pollutant emissions and pollution levels. Our findings demonstrate that, over the past two decades, urban sprawl has resulted in decreases in accessibility to public transport, social services, and natural areas. We analyse CO2 traffic emissions, NO2 concentrations, and population exposure across urban areas in future scenarios of further sprawling or alternative compacting land-use development. Results indicate that a compact future scenario reduces transport CO2 emissions and urban NO2 levels, though increases in population density raise exposure to air pollution. A sprawl future scenario increases CO2 and NOx emissions due to longer commutes and congestion, and NO2 levels increase up to 25% in parts of the city. Several traffic abatement strategies were simulated, and in all simulations a compact city consistently yields the largest reductions in CO2 emissions and NO2 levels, implying that the best abatement strategy for combating negative consequences of sprawl is to reduce sprawling. In both city layouts, network-wide improvements of public transport travel times gave significantly reduced emissions. Combined, our findings highlight the importance of co-beneficial urban planning strategies to balance CO2 emissions reduction, and air pollution exposure in expanding cities.

Environmental pollutants in the terrestrial and urban environment. NILU OR
On behalf of the Norwegian Environment Agency, NILU - Norwegian Institute for Air Research in collaboration with NINA ¿ Norwegian Institute for Nature Research analysed biological samples from terrestrial urban regions for various inorganic and organic contaminants. Stable isotope analysis for nitrogen and carbon was carried out by the Institute for Energy Technology (IFE). Sample collection was carried out by the Norwegian Institute for Nature Research (NINA) and others. The purpose of this report is to provide an updated assessment of pollution present within the terrestrial urban environment in Norway. In the case of earthworms, urban sites were compared with reference sites.
Eggs of the terrestrial bird species golden eagle and pied flycatcher as well as liver from urban brown rats and urban and rural earthworms were investigated in this study.
