Diffuse PM10 emission from construction activities
Diffuse PM10 emissions are a main source of high PM10 concentrations in urban as well as in rural areas. However the knowledge of the source strength of such emissions is not easy to be determined. In order to improve the data base on emission factors for such sources on-site measurements of PM10 were adjacent to a stone quarry as well as in the ambient air of the Tradenberg tunnel during its construction. A typical fleet of construction machinery was applied to both areas. The air pollution measurements were compared to the PM10 emission factors, calculated using the mathematical models proposed by guidelines Austrian and German guidelines for the calculation of emissions from storage, transhipment and transportation of bulk materials. Because of the high deviation between calculated and measured ambient air pollution, it can be considered that the values given by guidelines strongly overestimate real world situations.
