Standard Dustscan Report
Directional Dust Rose
DustScan software automatically calculates two measures of nuisance dust:
1. Absolute Area Coverage (AAC%): a measure of the presence or absence of dust irrespective of colour; and
2. Effective Area Coverage (EAC%): a measure of the soiling or the 'darkness' of dust.
The standard DustScan report (see image top left) is generated for every DustScan sample processed. The report states AAC% and EAC% values for each 15° segment of the sticky pad as well as the averages for the sampling interval. Directional 'dust rose' plots (see image bottom left) for both AAC% and EAC% are also generated to graphically show the directions of dust sources and the extent of dust soiling respectively.
This technique naturally forms a two-stage assessment approach to the quantification of the impact of nuisance dust, very much like a hazard appraisal and risk assessment. AAC% thresholds can be used to identify the dust source and its magnitude (Hazard). EAC% thresholds can be used to rate the nuisance potential (Risk) of the dust. The significance levels for AAC and EAC are combined and shown in an assessment matrix for potential impact at the bottom of standard DustScan reports. For more information on the assessment matrix please see DustScan Guidance Note No. 3 which is available to download from our Downloads tab.
Standard reports can be issued in paper or electronic format (See Example Report below).
Dust rose plots can also be super-imposed onto site drawings (see our Services tab for more information).
The DustScan database stores sample analysis data of every sample processed. DustScan has accumulated an unprecedented historical record of site-specific dust data, this record is strictly confidential but can be accessed on request for periodic summary reporting.
