Where monitoring of an air emission point or boiler is required, this is often referred to as stack monitoring. Typically, such monitoring is carried out on boiler stacks, exhausts from printers and fume hoods, discharges from bag filters and thermal oxidisers. Where emission levels exceed limits, air dispersion modelling may be necessary to ensure there is no detrimental effect on ambient air quality.
Occupational or workplace monitoring
Where workers are exposed to dusts and vapours then occupational monitoring is necessary to ensure that the concentrations are below the published Occupation Exposure Limits (OELs) and Short Term Exposure Limits (STEL).
Ambient air monitoring
Ambient air monitoring is sometimes necessary to show that local air quality is not adversely affected by emissions by you or others. Ambient monitoring includes dust deposition, PM10, SOx and NOx and mercury.
Indoor Air Quality
People in homes and offices can be exposed unknowingly to a wide range of contaminants. These can cause health problems such as runny noises, itchy or dry eyes, headaches and nausea.
