Odour Monitoring Ireland Services: Dust Monitoring

Bergerhoff Dust Monitoring

The Bergerhoff dust method is carried out on most waste sites, landfill sites and building sites. It is a way of measuring airbourne dustfall occurring from manmade activities that may attribute to environmental adverse effects. The Bergerhoff method is accepted by the EPA and Local Authorities as part of waste or IPPC licences. The method works by leaving out onsite dust jars for a period. The jars are analysed by means of evaporation and gravimetry, a result is obtained.

This result along with the amount of days the dust jar has been left out we can work out the dustfall per mg/m3/day. Dustfall limits are generally laid down in the planning permission for the site or in guidelines issued by the EPA.

Odour Monitoring Ireland provide dust monitoring services.

PM10 & PM2.5 Monitoring

The effects of inhaling particulate matter has been widely studied in humans and animals and include asthma, lung cancer, cardiovascular issues, and premature death. The size of the particle is a main determinant of where in the respiratory tract the particle will come to rest when inhaled. Larger particles are generally filtered in the nose and throat and do not cause problems, but particulate matter smaller than about 10 micrometres, referred to as PM10, can settle in the bronchi and lungs and cause health problems. The 10 micrometer size does not represent a strict boundary between respirable and non-respirable particles, but has been agreed upon for monitoring of airborne particulate matter by most regulatory agencies. Similarly, particles smaller than 2.5 micrometres, PM2.5, tend to penetrate into the gas-exchange regions of the lung, and very small particles (< 100 nanometers) may pass through the lungs to affect other organs. In particular, a study published in the Journal of the American Medical Association indicates that PM2.5  leads to high plaque deposits in arteries, causing vascular inflammation and atherosclerosis - a hardening of the arteries that reduces elasticity, which can lead to heart attacks and other cardiovascular problems. Researchers suggest that even short-term exposure at elevated concentrations could significantly contribute to heart disease.

PM10 Airborne particulate matter (PM) consists of many different substances suspended in air in the form of particles (solids or liquid droplets) that vary widely in size. The particle mix in most countries is dominated by fine particles (less than 2.5 micrometers in diameter) generated by combustion sources, with smaller amounts of coarse dust (between 2.5 and 10 micrometers in diameter).

Particles less than 10 micrometers in diameter that includes both fine and coarse dust particles pose the greatest health concern because they can pass through the nose and throat and get into the lungs which have severe health effects on the respiratory tract.

Particles larger than 10 micrometers in diameter that are suspended in the air are referred to as total suspended particulates (TSP).  These larger particles can cause irritation to the eyes, nose and throat in some people, but they are not likely to cause more serious problems since they do not get down into the lungs.

We have an extensive in house capabilities for both gravimetric and continuous monitoring for Particulate monitoring. Odour Monitoring Ireland provide PM10 & PM2.5  monitoring services.
