| description | The PM10 emission efficiency of soils has been determined through different methods. Although these methods
imply important physical differences, their outputs have never been compared. In the present study the PM10
emission efficiency was determined for soils through a wide range of textures, using three typical methodologies:
a rotary-chamber dust generator (EDG), a laboratory wind tunnel on a prepared soil bed, and field measurements
on an experimental plot. Statistically significant linear correlation was found (p < 0.05) between the PM10
emission efficiency obtained from the EDG and wind tunnel experiments. A significant linear correlation
(p < 0.05) was also found between the PM10 emission efficiency determined both with the wind tunnel and the
EDG, and a soil texture index (%sand+%silt)/(%clay+%organic matter) that reflects the effect of texture on
the cohesion of the aggregates. Soils with higher sand content showed proportionally less emission efficiency
than fine-textured, aggregated soils. This indicated that both methodologies were able to detect similar trends
regarding the correlation between the soil texture and the PM10 emission. The trends attributed to soil texture
were also verified for two contrasting soils under field conditions. However, differing conditions during the
laboratory-scale and the field-scale experiments produced significant differences in the magnitude of the
emission efficiency values. The causes of these differences are discussed within the paper. Despite these differences,
the results suggest that standardized laboratory and wind tunnel procedures are promissory methods,
which could be calibrated in the future to obtain results comparable to field values, essentially through adjusting
the simulation time. However, more studies are needed to extrapolate correctly these values to field-scale
conditions. |
