Comparison of PM10 washout on urban and rural areas

Abstract

This paper reports the results of research into the effectiveness of scavenging of PM10, resulting from the occurrence of solid and liquid hydrometeors. The measurement campaign was undertaken over 7 years and involved the registration of PM10 in areas which have different aerosanitary conditions (i.e. urban and undeveloped rural area). The analysis involved 426 observations taken at constant time intervals of 0.5 hour. The measurements of the concentration of PM10 were performed by means of a reference method accompanied by concurrent registration of basic meteorological parameters. It was indicated that in a urban location, the intensity of the local emission sources is a principal factor influencing the value of mass concentration changes and the effectiveness of the dust scavenging that accompanies a given type of precipitation. It was also noted that for the same intensity of precipitation, only the deposition of convective rainfall and long-term large-scale precipitation do not lead to statistically relevant differences in the value of mass concentrations of dust for both areas. It was indicated that during solid and liquid frontal precipitation of light intensity (< 0.5 mm·h -1 ), the effectiveness of PM10 removing is less in rural area. It was statistically proven that continuous precipitation of constant intensity and duration exceeding 2 hours has a similar effect of purifying the ambient air in both locations. The study revealed that short-term solid precipitation provides better characteristics of scavenging of PM10 compared with classic rainfall

Sustainability of Waste Materials in Affinity with Ecologically Sustainable Development: A Case Study of Kosovo

“…Based on the research findings presented with the best practices of literature review, it is recommended that ecological awareness for qualitative environmental waste management, and awareness for recycling processed materials, originate a nonnegotiable ecological development strategy. Moreover, it should be especially implemented in high-density housing, and it can be explained also by the thermal conditions [17], as predecessor model of future hybrid high-rise architectural structures. Furthermore, the recommendations of this study are as follows: − Promoting, developing and implementing ecological actions for sustainability; − Implementing the incinerators for burning the medical and common waste; − Implementing projects, and programs for recycling, treatment and reuse of the waste; − To increase inter-institutional cooperation in the sustainable development; − Raising awareness to youth, about waste disposal in appropriate places and perform obligations to communities; − Building the waste treatment plants in every municipality of Kosovo.…”

“…Hence, there are no oppression and compacting of waste, and linkage of polluted water is a common occurrence. This has affected the space of waste to be reduced [15][16][17]. There are no licensed incineration plants for burning hazardous waste in Kosovo.…”

Optimization of ventilation system in the open office space

“…In highly urbanized regions, where the open space offices are popular, the outside air often exceeds the acceptable concentration of pollutants. However, given the concentration of oxygen and carbon dioxide in the air inside and outside the building, the outside air is still commonly called fresh [2][3].…”

The Effect of Landscape on the Diversity in Urban Green Areas

“…Urban ecosystems are characterized by high-density human habitation, intense transportation processes, and only remnants of natural habitats [1,2]. At the same time, permanent contamination is experienced in the territory of modern settlements through atmospheric precipitation and dust settling [3,4]. Pollutants can be influence invertebrates [5].…”
