DS100-D metal recycling wharf dust monitoring

DS100-D metal recycling dust

The DS100-D combines the DS100 sticky pad directional dust gauge with the DD100 DustDisc settlement gauge, the DustDisc simply replaces the standard DS100 rain guard.


The passive directional gauge samples fugitive dust in flux from 360° around the sampling head to determine the direction/s from which dust has arisen. The passive settlement gauge samples dust depositing out of the air. 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.


The DS100-D is easy to install and operate. It can be used to collect comprehensive dust monitoring data from a range of sites and environmental conditions. The combined unit allows for the simultaneous collection of both dust flux and dust deposition data. No other combined directional and depositional dust monitor has its range of capabilities.


Dust mass measurements are sometimes required by site conditions and DustDisc samples can be analysed to report dust mass in mg/m2/day as well as being suitable for further physical and chemical tests. Similarly dust can be removed from specific directional sectors of the DS100 sticky pad samples for parallel testing and analysis.

DS100-D construction site boundary monitoring

DS100-D construction site dust

The DS100-D is widely used across industry and at a wide range of sites both in the UK and abroad. Installation sites include those associated with construction and demolition, land remediation and reclamation, quarrying and mineral processing, waste transfer and recycling, power generation and transport.

The DS100-D is ideal for:

 

  • Baseline monitoring for both directional and depositional dust levels
  • Routine site boundary or fenceline monitoring
  • Investigating allegations of dust nuisance at potential receptors
  • Compliance monitoring
  • Assessing the effectiveness of dust suppression measures
  • Locating fugitive dust pathways and sources

DS100-D dust gauges are supplied with 2 directional sampling cylinders and 2 DustDisc cases to allow for continuous dust flux and 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 DS500-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.

 

DustDisc samples are suitable for our unique, release gravimetric analysis. Our 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 the directional samples, 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.

 

DustScan directional AAC% & EAC% report

DustScan dust monitoring 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. Please see the DustDisc Reporting page to see an example DustDisc report.

 

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. Meanwhile, dust mass settlement rate can be calculated using the approximation method developed by Beaman and Kingsbury (1984).

 

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