Opis:: Pollution caused by road transportation is the major factor affecting human health and adversely affecting the global warming. In the study, a system dynamics model has been applied to forecast vehicle emissions from road transport to evaluate policies in the transportation management. The proposed model was applied to evaluate and compare three transportation policy scenarios including road expansion, public transit incentive and enforcement of quality norms for vehicles. The pollution emission data is taken in Chennai, Tamil Nadu. The pollution in the study area will increase substantially if no management plans are implemented. The impact of population increase on transportation pollution has also been considered. It was found that among the proposed policies, implementation of the transit incentive policy to adopt public transports and the implementation of Bharat Stage IV norms for vehicles proved to be efficient in reducing the transport pollution to a great extent.

Opis:: The conditions have been examined under which selected groups of microorganisms might be applied to prevent or significantly reduce the generation of odour from the processing and storage of the wastewater sludge. A series of experiments were conducted on a semi-industrial scale, using effective microorganisms (EM) activated in molasses solutions. The analysis of the results showed that the biopreparation modified the biochemical processes most effectively when a structural material was added to the sludge. The processing of the sludge with added EM caused a 20–26% reduction in odour emissions, despite an increase in ammonia emissions. It also led to a higher dry matter content, which indicates a better dewatering ability of the sludge treated with EM. It can be concluded that the treatment of wastewater sludge with EM and the structural material when the C/N ratio is low can help achieve the desired goal of reducing the odour emission.

Opis:: The impact of the fuel feeding mode (continuous or periodic with various stand-by/operation time ratios) on carbon monoxide (CO) and nitrogen oxides (NO, NO_x) concentration values in the flue gas was analyzed for coniferous wood pellet firing. Experiments were performed using a 20 kW water boiler equipped with an under-fed (retort) wood pellet furnace located in a full scale heat station simulating real-life conditions. Impact of oxygen concentration and temperature in the combustion chamber on the concentrations of carbon monoxide and nitrogen oxide have been examined. It was concluded that the commonly used periodic fuel supply does not necessarily cause an important increase of the concentrations of carbon monoxide compared to those in the continuous fuel feeding mode. Continuous fuel supply can even imply higher concentrations of carbon monoxide when fuel and air streams are not chosen properly.

Opis:: The ambient concentrations and elemental composition of particles with aerodynamic diameters between 30 and 108 nm (quasi-ultrafine particles, q-UFP) were studied. The data came from 6 sites in Katowice and Zabrze, big cities in Upper Silesia, where particulate matter was sampled at urban background site and crossroads in Katowice and Zabrze, at highway in Katowice, and at urban road in Zabrze. The ambient concentrations of q-UFP and of 24 q-UFP-bound elements at these six sampling sites have been discussed in the paper. The q-UFP mass concentrations in Upper Silesia did not appear high, they were not higher than in other areas. The percentages of the total mass of the examined elements in the q-UFP mass suggest that in Upper Silesia, within a typical residential area, q-UFP consist mainly of primary matter. At the sites under strong influence of road traffic emissions, where the contributions of the examined elements to the q-UFP mass were small, most probably, carbonaceous matter and elemental carbon build the core q-UFP mass. The majority of the elements in q-UFP are anthropogenic. Clear effects of local PM sources can be seen on the ambient concentrations of q-UFP-bound Al, Si, S, Cl, K, Sc, Ti, V, Cd, Cr, Mn, Co, and Sb.

Opis:: Despite solutions available in the Polish law system which could be used in conflictual situations connected with odour emission, the amount of odour complaints in Poland has been increasing. Currently applied legal solutions in Poland used in private-law and public-law ways in odour issues have been characterised. The results of analyses of available and developed technical solutions aiming to eliminate odour nuisance have been presented as well. Additionally, the results of research conducted in laboratory conditions and in chosen municipal waste management and industry facilities have been displayed. A conducted analysis pointed out the limited character of Polish legal solutions concerning odours. Therefore, the need to create an administrative and legal regulation dedicated directly to the preventing odour nuisance in Poland was emphasized. Such a regulation should include issues concerning, inter alia, emission, immision and technological standards.

Opis:: Two heat pump systems with the highest energy performance indicators were chosen for an analysis. Those most efficient systems for heating and cooling are ground source heat pumps (GSHP) and the exhaust air heat pumps (EAHP). Consequently, two cases (case A and case B) with different pump configurations were related to a reference case R represented by gas-fired boilers covering heating needs and compression refrigeration units ensuring cooling needs. Technical assessment in the form of coefficients of performance as well as primary energy ratings were completed. An environmental impact taking into account CO2, SO2 and NOx emissions of analysed heat pump systems was also evaluated.

Opis:: The analysis of heat losses and thermal efficiency of the steam system used for plywood dryers before and after its modernization has been presented. In the wood industry, mainly pressure-free condensate return systems are used. An existing open condensate return system has been improved by the application of a closed condensate tank in order to eliminate secondary steaming. The tested system consisted of three basic parts. One of them was a boiler plant producing superheated steam. Steam and condensate transfer grids connecting the boiler plant with the dryer constituted the next part of the tested steam system. The latter element was a processing device for plywood drying. The application of the closed condensate return system has increased the efficiency of the tested steam system by 15.5%. This resulted in lower emissions of contaminations to the atmosphere. The results of the test were also used to define basic economic indicators of the system in order to determine profitability of its installation.

Opis:: The methods used to the identification of odour concentrations from public utility objects, under Polish legal regulations have been presented with exemplary results of measurements by the dynamic olfactometry and model calculations. The results of the study indicate the usefulness of the dynamic olfactometry in determining odour concentrations (from point and area emission sources located in public utility objects) suitable in odour emissions calculations. Based on results of such calculations, it is possible to determine odour concentrations in the receptor points and to evaluate olfactory impact range of considered objects, taking into account all types of odour sources affecting the quality of air in the area under study. Selected methods – as an alternative to field research: measurements in the grid and in the plume – can be less time and cost consuming but also require careful planning the number of samples and proper selection of representative sampling areas, especially in the case of the area sources.

Opis:: Emission concentrations from the landfill Štěpánovice have been examined. Measurements were carried out in the years 2004–2011. The results of the study were used to diagnose the emissions of CO2 as important landfill gas components. They indicate that the concentration of CO2 emissions and the annual sum of these emissions do not exceed the reporting thresholds and therefore, the landfill does not meet conditions for being included in the integrated register of polluters.

Opis:: Empirical relationships between carbon dioxide emission, imports, exports, and population have been investigated. An empirical model with carbon dioxide emissions, structure and scale of import and exports, populations was built Using ridge regression analysis and observed data from 1985 to 2006 in China, we examined the relationship between each part of carbon dioxide emission and corresponding coefficients, including GIV (gross imports value), GXV (gross exports value), and P (populations). The results have shown that the increasing trend in TCOE (total carbon dioxide emissions) was determined by the exports, while its standard level is determined by population. Increasing the imports may reduce TCOE. Considering working to expand economy, the best ways for China to reduce TCOE are to introduce advanced technology and take actions to guarantee strict execution of cut-emission policy. Although the increasing imports also can reduce TCOE, it is not reasonable for the global cut-emission policy. To control population is not applicable as the immense population base, so government's publicity for low-carbon live is a necessary and feasible way to reduce carbon dioxide emission.
