Astron was engaged by DBP to implement a real time monitoring program for particulate matter associated with construction works, ground disturbances, vehicle movements and emissions in close proximity to residential properties within the West Pilbara region of Western Australia.
Particulate matter can be any particle that is either 10 micrometers or less (PM10) or 2.5 micrometers or less (PM2.5). Due to the size range of these particles, they can make up large proportions of dust and can be drawn deep into the lungs. PM10 & PM2.5 are produced by a wide range of industrial and mineral processing as well as bush fires and dust storms, with these activities and events occurring throughout Western Australia.
People are continuously exposed to particulate matter. Higher exposure levels are associated with urban and industrial areas due to the increase in potential sources. It is well known that there are significant health risks associated with exposure and inhalation of these particles. Under the National Environmental Protection Measures (NEPM) of Ambient Air Quality, employers have a duty to ensure that the exposure to particulate matter does not exceed the relevant regulatory standards over the course of an averaged 24 hour period. Achieving this requires using appropriate strategies to recognize potential emissions sources and real time monitoring to evaluate exposure standards.
Astron implemented an extensive program over a two month duration, requiring real time monitoring of exposure levels and metrological conditions. This allowed us to accurately assess the risk posed from particulate matter, the quality of ambient air, the potential source of emissions and the relevant daily exposure levels.
