Nicholls Colton – PM10 and Nuisance Dust Monitoring

PM10 and Nuisance Dust Monitoring

PM10 Dust Monitoring

PM10 Dust is defined as dust which has a particle size of less than 10 µm. Dust of this size is capable of being inhaled into the lungs, which can then lead to adverse health. The National Air Quality Strategy objectives require PM10 levels to be measured, and there are defined maximum limits.

Dust can be generated naturally for example by wind and dry conditions, but it is often generated by human activity. Construction, demolition, quarrying, waste activities etc all give rise to dust, and this must be controlled, particularly PM10.

PM10 Dust monitoring differs from Nuisance Dust monitoring in that it measures particulate size by volume in real time.

Nicholls Colton Group measure PM10 using monitors which can be deployed inside or outside in a variety of locations. The equipment can run for a few minutes or a number of days continuously, using our external power sources, and weather protection.

Our PM10 monitors are typically serviced weekly, when the data is downloaded and the unit and power source are serviced. Our PM10 reports indicate particulate levels, humidity and temperature.

In addition to measuring PM10, our EVM7 model is also capable of measuring VOC and CO2 levels.

 

Nuisance Dust Monitoring

Nuisance Dust is dust which is coarse in size (greater than 10 um) and which is often perceived or considered by people to be an annoyance – for example it may coat surfaces or it may be a visible ‘cloud’.

Dust can be generated naturally for example by wind and dry conditions, but it is often generated by human activity. Construction, demolition, quarrying, waste activities etc all give rise to dust, and this should be controlled.

Nicholls Colton Group utilise Deposit Gauges for measuring Dust Deposition (volume of particles deposited), incorporating a Directional Gauge to indicate direction from source of the dust.

Gauges are left in-situ for at least one week, during which time the dust is collected. Filters are typically replaced each week, and the equipment is thoroughly rinsed to ensure that all deposited dust is collected for analysis in the laboratory. Directional dust is measured, from a “sticky pad” using an electronic instrument, to indicate compass direction.

We can advise on the location and number of gauges for a variety of applications, including remediation and development projects as well as industrial dust generation.

This is a highly cost effective way of accurately measuring levels of Nuisance Dust.
