Abstract

The author presents the search for the identity of individuals and families displaced after World War II from Vilnius to Gdańsk in the context of the urban community integration. Gdańsk being a city where the population after the war was almost fully replaced, becomes in this sense a kind of laboratory of social integration processes. The text serves as an introduction to the topic and is based on the results of the pilot qualitative research conducted within the The Common Room Gdańsk” (2013–2015) project coordinated by prof. M. Mendel. The analyses are a contribution to the reflection on identity determinants of integration processes within the urban community, also in relation to contemporary times. When discussing the issues of identity, the author points to the importance of the turning point which was the end of World War II, and the experience of expatriation in the spatial and socio-cultural context.

Abstract

The paper investigates the air quality in the urban area of Warsaw, Poland. Calculations are carried out using the emissions and meteorological data from the year 2012. The modeling tool is the regional CALMET/CALPUFF system, which is used to link the emission sources with the distributions of the annual mean concentrations. Several types of polluting species that characterize the urban atmospheric environment, like PM10, PM2.5, NOx, SO2, Pb, B(a)P, are included in the analysis. The goal of the analysis is to identify the most polluted districts and polluting compounds there, to check where the concentration limits of particular pollutants are exceeded. Then, emission sources (or emission categories) which are mainly responsible for violation of air quality standards and increase the adverse health effects, are identified. The modeling results show how the major emission sources – the energy sector, industry, traffic and the municipal sector – relate to the concentrations calculated in receptor points, including the contribution of the transboundary inflow. The results allow to identify districts where the concentration limits are exceeded and action plans are needed. A quantitative source apportionment shows the emission sources which are mainly responsible for the violation of air quality standards. It is shown that the road transport and the municipal sector are the emission classes which substantially affect air quality in Warsaw. Also transboundary inflow contributes highly to concentrations of some pollutants. The results presented can be of use in analyzing emission reduction policies for the city, as a part of an integrated modeling system.
