GPECS offers ambient air monitoring consultancies based on a vast array of experience in designing, managing and operating case-specific monitoring programmes on behalf of governmental departments, regulatory bodies, local authorities and industry. Typical monitoring activities include:

  • Industrial / Indoor Air Quality Investigations
  • Organic / Biological / Mould Contamination
  • Sick Building Surveys
  • Industrial Air Monitoring

GPECS has access to a fleet of mobile air quality monitoring laboratories, with full meteorological monitoring capabilities, and comprehensive real time analysis of key pollutant species. Our air quality measurement expertise covers a range of species, including organic and inorganic pollutants, and airborne particulate matter. We offer an impartial choice of measurement techniques from sophisticated open-path or automatic analysers to practical, cost-effective samplers and diffusion tubes.

GPECS also routinely designs, manages and undertakes wide-scale monitoring of ambient concentrations of additional pollutant species over long and short term. All GPECS ambient air quality monitoring staff are trained and their methods are routinely audited.

GPECS can offer support services including dispersion modelling for Air Quality Impacts, and odour nuisance assessments. Industries using our expertise include:

  • Chemical Manufacturers
  • Oil Refineries
  • Electricity Power Generation


Dust Assessment

Dust is generated by a large variety of industrial and construction activities. Where dust generation is unchecked, it can lead to a significant nuisance to neighbours. GPECS has both long and short term dust monitoring capabilities.

Short term measurement is often used to quantify an existing dust problem. It is undertaken using a combination of hand-held dust meters, and air filtration. It is useful in obtaining a snapshot of the dust generation on a site, which can be used to identify areas, or specific equipment, on a site responsible for dust generation. Once identified, any dust mitigation measures can be focused on these problem areas.

Directional Dust gauges, Frisbee Dust Deposition gauges and Slide gauges are used for long term monitoring to provide an accurate measure of the dust in an area, both on and off a site of interest. These methods are often used for assessing the environmental impact of dust both before and after a development.

  • Gravimetric, TEOM monitoring for PM10 particulates
  • Suspended dust sampling using high volume sampling
  • Dust deposition using Frisbee gauges (BS1747:Part 1: 1972)
  • Directional dust deposition (BS1747: Part 5: 1972)
  • Sticky pad assessments
  • Surface soiling level assessments.
