DustDisc 1.7 deposit gauge

The DustDisc is an innovative, low-cost dust settlement sampler. It comprises a horizontally-mounted sticky pad, located inside a convenient handling case that slides into a sampling head (complete with bird-strike guard). DustDiscs can be used to measure dust deposition as a stand-alone device or in conjunction with our directional gauges. When combined with our DS500X PM10 gauge (DS500X-D), dust settlement, dust flux and gravimetric PM10 concentrations can be monitored in one installation.

When used in conjunction with the DS100 directional sampler (DS100-D), the combined unit is ideal for comprehensive site boundary monitoring.

DustDisc options available include:

  • DustDisc - Stand-alone sticky pad dust settlement sampler, supplied with a mounting bracket
  • DustDisc 1.7 - As above but supplied with a 1.7m mounting post instead of a bracket
  • DS100-D - A combined directional and depositional sticky pad dust gauge
  • DS500X-D - A combined directional and depositional dust and gravimetric PM10 sampler
  • DustDisc upgrade - Compatible with either the DS100 or DS500X gauges
The stand-alone DustDisc samplers are less expensive than other methods for monitoring dust deposition such as Frisbee gauges. The dust samples collected by DustDiscs are also much more readily transported because they are light weight. One drawback of using Frisbee gauges can be the high cost of transporting samples for analysis because the collection bottles often also collect large volumes of rainwater. With DustDiscs, rainwater runs away through drainage holes in the sample holder. Frisbee sample bottles can also leak their contents in transit. DustDisc samples are safely contained in a small case that can be easily transported at low cost by post.

DustDisc dust deposit gauge

Dust deposition sampling is the measurement of dust falling out of the air at a particular point. It should therefore be monitored where dust fallout is potentially a problem – i.e. at receptors surrounding a site, not normally at the site boundary.

 

As a stand-alone gauge the DustDisc is very effective for monitoring dust deposition at dust receptors. Its relatively small size allows for it to be installed discretely on windowsills or onto street furniture etc.

The DustDisc is ideal for:

  • Baseline monitoring for dust deposition levels
  • Routine site fenceline/boundary deposition monitoring
  • Dust monitoring in built up urban environments
  • Investigating allegations of dust nuisance at potential receptors
  • Compliance monitoring

DustDisc samplers are supplied with 2 DustDisc cases to allow for continuous dust deposition sampling.


NO SPECIALIST PROCEDURES ARE NEEDED IN THE FIELD TO COLLECT AND EXCHANGE THE SAMPLES.

 

DustDisc sticky pad dust samples should be collected over the period of 1 – 2 weeks. When the DustDisc is used in conjunction with our directional dust gauges (the DS100-D and DS500X-D), comparisons can be made between the deposited dust data and the directional flux data more readily when sampling periods are regular and synchronized. We strongly recommend using our combined directional and depositional gauges as determining the direction of a dust source is of far greater significance in dust nuisance investigations than deposition rates alone.

The DustDisc 1.7 can be used as an alternative to Frisbee-type deposit gauges. The DustDisc 1.7 is set at the specified Frisbee sampling height (as recommended by the SEI-Y protocol). Our new sticky pads enable us to remove the dust after sealing, this means we can provide gravimetric (mg/m2/day) as well as optical (AAC% and EAC%) dust deposition data.

As with our other samplers, DustDisc samples must be returned to DustScan offices for analysis. DustDisc samples are removed from their protective cases 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.

 

DustDisc deposited AAC% & EAC% report

DustScan DustDisc report

DustDisc samples can be measured for settlement AAC% and EAC% and dust mass. As with the directional samples this is reported as the total for the sampling interval and the daily rate.

 

The expression ‘nuisance dust’ typically relates to the visual impact of dust settlement, and is normally generated by dust in flux. The effect caused by dust nuisance is often measured as EAC% (Effective Area Coverage) and there are ‘custom and practice’ nuisance criteria for EAC and deposited dust mass.

The DustDisc enables dust settlement monitoring with the same criteria as for flux monitoring. The settlement data may be used in conjunction with the directional data – for example by considering different AAC (Absolute Area Coverage) to EAC ratios to assess the significance of dust from different directions.

 

Samples can also be assessed using Beaman and Kingsbury, (1981) criteria: (0.5% EAC/day is considered to lead to “possible complaints”; 2.0% EAC/day to lead to “probable complaints” and 5.0% EAC/day may lead to “serious complaints”).

 

New sticky pads have been developed to provide samples for gravimetric (mass) and other analyses. We are currently undertaking co-locational gauge testing trialing our DustDisc alongside a Frisbee-type monitor to compare their sampled deposition rates.

 

DustScan sticky pads also allow samples to be readily analysed for dust grading, mineralogy and chemistry.
