scope:

The convention method here described is used for determining airborne dust deposition according to the Bergerhoff method [1; 2].

Dust deposition in terms of this guideline is a mass flow density, i.e. mass per unit area and unit time. It is calculated from the dry residue mass of the collected deposition sample, the exposure period and the aperture size of the jar collector. The dust deposition is not identical with the atmospheric deposition or bulk deposition as defined in VDI 4320 Part 1. As the method presented in this guideline only determines the dry residue, it is not intended to be used for the determination of the bulk deposition or the total deposition.

The method lends itself in particular to the following applications:

• dust deposition measurements as per TA Luft, the Clean Air Regulations of Switzerland (Luftrein halte-Verordnung der Schweiz (LRV)) or the measurement concept pertaining to the Air Quality Control Act of Austria (Immissionsschutzgesetz- Luft).

• plant-specific measurements (dust deposition in the surroundings of an industrial plant)

• determination of dust deposition in high-traffic areas or in urban and rural areas (e.g. spatial distribution and temporal trends)

• sampling for chemical analysis of deposited dust, e.g. as per guidelines VDI 2267 Part 7, Part 14, Part 15 and Part 16 (elements)

• sampling for the determination of arsenic, cadmium, lead and nickel concentrations as per DIN EN 15841

Note: This guideline supersedes guideline VDI 2119 Part 2 published in 1996.
