    Opis:
    This article aims to examine the emission of pollutants utilising transport in different points of the city in question at two different intervals, then show whether the means of transport negatively affects the city through pollution. The study of air pollutant emissions from transport sources is a key aspect towards solving problems related to environmental pollution. A study on the measurements of selected PM10 and PM2.5 pollutants to be able to determine the quality of air from transport sources in Pila at different times of the year and with appropriate assumptions regarding the appropriate distance by the road is included in this article. This study analysed data on air pollutants and compared it with the results of the Chief Inspectorate for Environmental Protection. This made it possible to propose solutions for the development of the air condition in Pila.

    Opis:
    The paper presents a complex analysis of the presence of various pollutants (CO2, CO, NO, NO2, CH4, TNMH, C6H6) in the vicinity of sites intended for open burning and open detonation of explosives. Previously obtained data (measured field data on a representative sample) regarding the emission factors of pollutants originating from different types of explosives have been used. To predict the atmospheric dispersion of reactive agents, the ADORA and ALOHA models were used. Comparative analysis was performed with computational and experimental data on the emission of detonation products using regression analysis of the obtained emission coefficients. The overall results show satisfactory values of correlation coefficients. The prediction power of used methods increased as follows: ADORA (the smallest error), ALOHA E/A (0.43) and ALOHA E/A 0.67.

    Opis:
    The road pollutant emissions, above all in urban context, are correlated to many infrastructural parameters and to traffic intensity and typology. The research work on road junction geometry, carried out in European research centres, has recently allowed to design new road intersection types which are of undoubted interest, especially in terms of traffic functionality and safety, like the flower roundabouts (in which right-turn manoeuvres do not conflict with the circulating flow). The main objective of this paper is to propose a model for the estimation the capacity, delay, levels of service and the pollutant emissions into flower roundabouts. A comparative analysis between conventional roundabout and flower roundabout has been carried out in terms of CO, CO2, CH4, NO, PM2,5 and PM10 vehicular emissions, evaluated by mean of COPERT Software which is developed as a European tool for the calculation of emissions from the road transport sector.

    Opis:
    The test procedure for the pollutant emissions from light-duty vehicles is currently under verification carried out at the international level. For this purpose, GRPE (Groupe des rapporteurs sur la pollution et energie) – the body developing UNECE regulations proposals - has set up a task group WLTP (Worldwide harmonized Light vehicles Test Procedure) which is supposed to prepare a new GTR (Global Technical Regulation) relating to this procedure. The development of light-duty vehicles, leading to the reduction of pollutants emissions, caused the increase of the requirements for their test procedure. A large number of factors associated, inter alia, with the test equipment affects its accuracy, repeatability and reproducibility. In the ongoing analysis attention is paid even to factors, which affect test results in a relatively small way, and which have been overlooked yet. One of the problems to which attention is paid is the impact of pollutant concentration in the dilution air in the CVS (constant volume sampler) system on test results. The CVS principle is accepted as the standard method to determine light-duty vehicle exhaust emissions on chassis dynamometer test cells worldwide. It was introduced in the early 1970s. One of its drawbacks is that it introduces an error resulting from the fact that the contractual DF dilution factor, rather than the actual dilution ratio DR, is used for the correction of concentration measurement results. The article discusses this error for different type of engines used in light-duty vehicles and different pollutants subject to measurements.

    Opis:
    An industrial planning is made based on the optimization model. Factor analysis was used to reject relativity among the environmental indicators. Then, thirty nine industries were clustered into four clusters. Lastly, optimization model was used to plan the industrial structure. Adjusting the industrial structure, it is difficult to reduce vast SO2, smoke, and dust with total industrial output value growth; the air pollutant emission only can be decreased by 10%. The parameters of smoke emission are limited constrains for the optimization. The reasonable and feasible way to solve the problem is to introduce the lower smoke emission technique of the cluster 2 and 4 industries.
