The aim of the work was to assess the temporal distribution of NO2 and NOx concentration in relation to wind direction and to determine the effect of major meteorological elements on the size of NO2 and NOx concentration in northwest Poland. In the area of the research, in the period from 1st May 2005 to 30th April 2007 the highest average concentration of NO2 and NOx, both during cold and warm half-years, occurred with southeasterly wind, and the lowest with south-westerly wind for NO2 and with north-easterly wind for NOx. The highest determination coeffi cients and, at the same time, the smallest estimation errors for multiple regression equations, describing the dependence of the concentration of NO2 and NOx from meteorological elements, were obtained with westerly wind in the cold half-year and with south-westerly wind in the warm half-year.
Sustainable development is a concept that appears more frequently in the context of urbanized cities. Rational management of city logistics and urban population change of consciousness becomes a priority. The purpose of this publication is to emphasize the need for changes in city logistics, to characterize the concept of sustainable transport and to present the results of research on: the views of residents of Podkarpacie on choosing alternatives to the car, and urban transport concept. The research process was conducted in two stages. The first stage of the research was conducted in 2014 within its scope included the study compared the inhabitants of Podkarpacie to sustainable forms of transport. The second stage of the study carried out in 2015 was designed to examine whether the implementation of Intelligent Public Transport Management System, has changed the ratio of respondents to sustainable transport.
The state of the art of application of membrane techniques for air cleaning is presented. The most characteristic parameters of membrane separation of gases and vapours are described. Separation of gases and vapours has been applied practically in the industry for the following areas: removal of volatile organics from the air and from industrial waste flows, oxygen enrichment of air and vice versa and the membrane absorption process.
