The DustScan DS100 is a passive, directional sticky pad dust gauge. It samples fugitive dust in flux from 360° around the sampling head to determine the direction/s from which dust has arisen. The collected dust is measured in terms of AAC and EAC % (established annoyance/nuisance criteria) and, if subsequently needed characterised to determine the mass, particle size and chemistry. No other directional dust monitor has its range of capabilities.

The gauge is simple to install and can be used on a wide range of sites. It does not need a power supply and operates continuously in all weather conditions. The DustScan DS100 has been designed to be robust, inexpensive and unobtrusive.

Unlike other “traditional” methods of dust monitoring, DustScan directional sticky pad gauges are extremely difficult to tamper with. It is clearly evident if dust has been thrown onto the sticky pads or indeed if attempts have been made to scratch it off!

The DS100 gauge comprises a durable and resilient 1.6m post that can be screwed or strapped to existing site structures such as fences or walls. Where monitoring is required away from site structures and providing there is soft ground available, drive-in fencing met-post stakes can be used as a holder for the post. The monitoring head is fitted to the top of the post with a north-facing alignment peg at its base.

2 sampling cylinders, pre-fitted with dust collection slides (sticky pads), are supplied with each gauge to allow for continuous directional dust sampling. A sampling cylinder is fitted onto the monitoring head and it is orientated to north by fitting its notch over the alignment peg. The cylinder is held in place by a screw-on rain guard.

2 sample transport flasks are also supplied per instrument. These are used to prevent sample contamination after sampling cylinders have been removed from the gauge. The flask end caps are recessed to locate the cylinder securely and away from the sides of the flask. Sample flasks are returned to DustScan for analysis in purpose-built 4 or 6 section transport boxes.

The DS100 was originally developed to provide the minerals industry with a low-cost directional nuisance dust sampler. It is now not only used by most of the major mineral operators in the UK at quarries etc. it is now widely used at landfill sites, demolition and construction sites, surface coal mines, waste transfer and recycling plants, remediation sites and many other works.

 

The DS100 is ideal for:

 

  • Site boundary monitoring
  • Determining nuisance dust propagation
  • Locating fugitive dust pathways and sources 
  • Assessing the effectiveness of dust suppression measures
  • Baseline nuisance dust investigations
  • Compliance monitoring

 

It has also been used for research purposes using a range of dust characterisation techniques and for mapping the dispersal of potentially hazardous materials in dust emissions from industrial sites.

Sealed directional sticky pad samples

DustScan directional sticky pads

Directional sticky pad dust samples should be collected over a sampling interval of no more than 2 weeks. Frequent and regular sampling ensures a meaningful dataset is obtained, and provides regular reports that can be used to help improve site management.

 

All sticky pad samples must be returned to DustScan offices for analysis. The samples are removed from their sampling cylinders and sealed using a transparent film. Sealed sticky pads represent a permanent record of collected dust which can be used for additional investigations (e.g. dust characterisation) or proof of evidence at a later date.

 

Sealed samples are scanned on flat-bed scanners. The whole sample is scanned, meaning that the DustScan system is less subjective and more repeatable than other sticky pad readers.

 

Sample scan image files are analysed using the latest DustScan DS2 software. The initial visual display shows the sample area of the sticky pad and the unexposed reference area (used for calibration).

 

The analysis software automatically masks out any erroneous material such as flies, seeds or fingerprints so that they are not incorporated into the analysis. Manual masking can also be utilised if any erroneous material happens to be the same colour as the dust.

 

Dust levels for each sample are assessed individually with approximately 150,000 data points being analysed per sample.

 

DustScan directional AAC% & EAC% report

DustScan directional dust report

DustScan software automatically calculates two measures of visible, 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 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 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 page.

 

Standard reports can be issued in paper or electronic (.pdf) format.

 

Dust rose plots can also be super-imposed onto site drawings (see our Dust Mapping page 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.
