CONTENTS

What is fine particulate matter (PM)?

Why do we monitor it?

What should PM monitoring achieve?

Is fine PM the only emission we can monitor?

What is visible ‘nuisance’ dust?

Why should we monitor it?

what is fine particulate matter pm
What is fine particulate matter (PM)?

‘Dust’ is defined in BS6069 Part 2 as particulate matter < 75μm (micron) diameter

Fine PM is essentially dust particles up to 10µm

Commonly referred to as PM10

Smaller size fractions (PM2.5, PM1 etc)

Inhalable, thoracic, respirable

‘Dust’ & fine PM are generic terms

What is fine PM?

  • Many potential sources
  • ‘Natural’ background dust
  • Fugitive industrial dust
    • Surface mining and minerals
    • Waste transfer and landfill
    • Land remediation
    • Secondary aggregates
    • Construction and demolition
    • Roads and transport
    • Agriculture
    • Stack emissions
why do we monitor fine pm
Why do we monitor fine PM?

LEGISLATION – since 1956 Clean Air Act

Air Quality Regulations (AQR) prescribe National Air Quality Strategy (NAQS) objectives – AQOs. Also WELs

Includes PM10 (not PM2.5 - yet)

Local Authority Air Quality Management (LAQM)

Exceedence of AQO = Air Quality Management Area (AQMA)

Fine PM monitoring usually a matter of compliance

BUT

Fine PM only represents a small fraction of most sites total dust emissions

Fine PM monitoring often specified at sites when it isn’t appropriate – regulatory burden with cost implications

what should pm monitoring achieve
What should PM monitoring achieve?

Effective monitoring should aim to answer:

1) How much dust/PM is there?

2) Where has it come from?

3) What’s in it?

Results of the compliance approach to monitoring only partly answer the first question

is fine pm the only emission we can monitor
Is fine PM the only emission we can monitor?

From: Good practice guide: control and measurement of nuisance dust and PM10 from the extractive industries (AEA, 2011)

what is visible nuisance dust
What is visible ‘Nuisance’ dust?
  • Poorly-defined: visible dust; dust annoyance, dust soiling) is not regulated
    • Short-term (acute) impacts
    • Long-term (chronic) impacts
  • Unlike PM10, limit values not agreed (custom and practice criteria / best practice guidance)
  • Range of passive monitoring approaches: dust mass or dust effect; dust deposition or dust flux
why should we monitor visible dust
Why should we monitor visible dust?
  • Visible dust can have annoyance impacts – loss of amenity, complaints etc.
  • Less expensive & more convenient to monitor
  • Directional visible dust monitoring can help determine the direction of dust & fine PM sources
  • Samples of visible dust can be readily analysed for metals, mineralogy and physical characteristics
  • Can also be used for compliance monitoring!

DustScan DS500X sampler

  • Combined gravimetric filter reference PM10 sampler & directional sticky pad visible dust gauge
  • Simultaneous measurements – 24hr PM10 concentration, directional AAC% and EAC% and deposited mass (with DS500X-D)
  • How much dust/fine PM is there?
  • Where has it come from?
  • What’s in it? (after specific analyses)
