The rate of air pollution is becoming a cause for worldwide concern because of its substantial increase. Different sources like combustion of fuels, release of smoke from industries etc are responsible for the pollution of air. The construction industry is a major contributor to air pollution in the form of dust. Most of the activities involved in the completion of a construction project contribute to the generation of dust in one way or another. There are many sources of dust in a construction site like the use of construction equipment, transportation activities etc. the dust thus generated can ill effects as well. But, the problem of dust pollution is not addressed properly mainly because of the lack of awareness in this area. Proper identification of sources of dust in sites, its health impacts etc can help generate awareness and also help in implementing control measures. This can help reduce dust pollution on site. Here, a residential building site is taken for the case study. A questionnaire survey is conducted for the workers to identify the negative impacts construction dust has and also to determine the most common dust control measures employed in site.

Zeitliche Entwicklung

Aufgrund einer zunehmenden öffentlichen Thematisierung der Auswirkungen von Feinstaub in der Atemluft auf die menschliche Gesundheit wird in dieser Studie die Feinstaubbelastung in Tirol durch Silvesterfeuerwerke untersucht. Messdatenreihen von städtischen Ballungsräumen aus dem Tiroler Luftgütemessnetz ab dem Jahreswechsel 2010/11 wurden analysiert und die zeitliche Entwicklung der Feinstaubbelastungen in der Silvesternacht, die maximalen Halbstundenmittelwerte, die Tagesmittelwerte vor und an den Neujahrstagen sowie der Einfluss der Witterung auf die Staubbelastungen ausgewertet. Generell konnte am Neujahrstag eine Zusatzbelastung an PM10- Feinstaub im Tagesmittelwert bis über das Dreifache nachgewiesen werden. Die Bestimmung der Metallgehalte (Al, Ba, Pb, Cr, Cu, K, Mn, Mg, Ni, Se, Sr, Ti, Zn, As, Bi, Cd, Rb) in den Feinstaubfraktionen PM10 und PM2.5 zeigte bei allen Metallen eine Konzentrationszunahme am Neujahrstag, wobei die farbgebenden Metalle einen Zuwachs um den Faktor 10 bis 50 erreichten. Bemerkenswert ist weiters, dass der Großteil der untersuchten Metalle in der Feinstaubfraktion PM2.5 vorgefunden wurde.

Purpose Dust (particulate matters) is very dangerous to our health as it is not visible with our naked eyes. Emissions of dust concentrations in the natural environment can occur mainly by road traffic, constructions and dust generating working environments. The purpose of this paper is to assess the ambient dust pollution status and to find out the association between PM concentrations and other determinant factors such as wind speed, ambient temperature, relative humidity and traffic congestion. Design/methodology/approach A cross-sectional study was conducted for two consecutive months (June and July, 2016) at a residential site (Defence Services Liver Hospital, Mingaladon) and a commercial site (Htouk-kyant Junction, Mingaladon) based on WHO Air Quality Reference Guideline Value (24-hour average). Hourly monitoring of PM2.5 and PM10 concentration and determinant factors such as traffic congestion, wind speed, ambient temperature and relative humidity for 24 hours a day was performed in both study sites. CW-HAT200 handheld particulate matters monitoring device was used to assess PM concentrations, temperature and humidity while traffic congestion was monitored by CCTV cameras. Findings The baseline PM2.5 and PM10 concentrations of Mingaladon area were (28.50±11.49)µg/m3 and (52.69±23.53)µg/m3, means 61.48 percent of PM2.5 concentration and 54.92 percent of PM10 concentration exceeded than the WHO reference value during the study period. PM concentration usually reached a peak during early morning (within 3:00 a.m.-5:00 a.m.) and at night (after 9:00 p.m.). PM2.5 concentration mainly depends on traffic congestion and temperature (adjusted R2=0.286), while PM10 concentration depends on traffic congestion and relative humidity (adjusted R2=0.292). Wind speed played a negative role in both PM2.5 and PM10 concentration with r=−0.228 and r=−0.266. Originality/value The air quality of the study area did not reach the satisfiable condition. The main cause of increased dust pollution in the whole study area was high traffic congestion (R2=0.63 and 0.60 for PM2.5 and PM10 concentration).

Abstract. The interactions between aeolian dust and anthropogenic air pollution, notably chemical ageing of mineral dust and coagulation of dust and pollution particles, modify the atmospheric aerosol composition and burden. Since the aerosol particles can act as cloud condensation nuclei, this affects the radiative transfer not only directly via aerosol–radiation interactions, but also indirectly through cloud adjustments. We study both radiative effects using the global ECHAM/MESSy atmospheric chemistry-climate model (EMAC) which combines the Modular Earth Submodel System (MESSy) with the European Centre/Hamburg (ECHAM) climate model. Our simulations show that dust–pollution–cloud interactions reduce the condensed water path and hence the reflection of solar radiation. The associated climate warming outweighs the cooling that the dust–pollution interactions exert through the direct radiative effect. In total, this results in a net warming by dust–pollution interactions which moderates the negative global anthropogenic aerosol forcing at the top of the atmosphere by (0.2 ± 0.1) W m−2.
