MONITORING OPTIONS

AirQuality Limited can offer a variety of monitoring options for the monitoring of PM2.5 including:

  • Beta Attenuation Monitor
  • Dustmote optical particulate monitor
  • High Volume Sampler

More detail on each of these options is shown below:

Beta Attenuation Monitor

The AirQuality Limited BAM-mote continuously measures TSP, PM10, PM2.5 or PM1 using beta attenuation. The BAM-mote is a fully integrated package consisting of a Beta attenuation monitor coupled with an on-board modem, datalogger, data storage and Global Positioning System.

  •  Continuous, non-stepwise measurement
  •  Long term, unattended operation
  •  Designed to meet AS/NZS 3580.11 2008
  •  Capable of measuring TSP, PM10, PM2.5 or PM1
  •  Low detection limit, high accuracy and resolution
  •  Realtime on-line access to instrumental data

Dustmote Optical Particulate Monitor

The AirQuality Limited Dustmote continuous optical particulate monitor uses near-forward light scattering technology in combination with a datalogger, communications and Global Positioning System.

PM2.5

Particulate matter (PM) pollution is a serious health issue in many urban areas. Particulate matter is a generic term used to describe a complex group of air pollutants that vary in size and composition, depending upon the location and time of its source.

The PM mixture of fine airborne solid particles and liquid droplets (aerosols) include components of nitrates, sulfates, elemental carbon, organic carbon compounds, acid aerosols, trace metals, and geological material. Some aerosols are formed in the atmosphere from gaseous combustion by-products such as volatile organic compounds (VOCs), oxides of sulfur (SOx) and nitrogen oxides (NOx).

The size of PM can vary from coarse wind blown dust particles to fine particles directly emitted or formed from chemical reactions occurring in the atmosphere. PM2.5 comprises particles with an aerodynamic diameter less than or equal to a nominal 2.5 microns. The official term is micrometer or one millionth of a meter, however, micron is still in common use.

From a health perspective, the size of the particles is important as it affects their ability to penetrate into the lungs and cause adverse health effects. The larger particles (e.g. those greater than 10 microns) tend to settle in the nose and mouth and are unlikely to pose a health risk.

Finer particles can penetrate further into the lung and alveoli and therefore may be associated with more severe health impacts. The mechanisms of formation (e.g. nucleation, coagulation and condensation for the finer fraction or the more abrasive formation systems of the coarser fraction) may also have implications for respiratory related health effects.
