Ambient Air Monitoring: Outdoor and Indoor
Gradko’s ambient air monitoring equipment is widely used to monitor both indoor and outdoor air quality. Continuous development allows us to provide equipment for a broad range of applications, covering short-term and long-term monitoring. Pollutants can be detected even at very low levels – limits of detection are typically in the low parts per billion (ppb) range.
Outdoor Air Sampling
- Traffic pollution
- Spatial assessments, roadside or urban background locations.
- Co-location with auto-analysers.
- Nitrogen dioxide, Sulphur dioxide, Benzene, BTEX and Volatile Organic Compound (VOC) emissions, including Petroleum Hydrocarbons, TPH, PAH, Landfill Suites.
- Landfill gas emissions
- Air quality monitoring or soil gas sampling to identify the distribution of hazardous pollutants or odours.
- VOCs, Mercaptans, Formaldehyde and Hydrogen sulphide.
- Agricultural emissions
- Farming practices can result in rural pollution including Nitrous oxide, Ammonia, and Pesticides.
- Industrial emissions
- Stack sampling and boundary emissions monitoring.
- Sampling of a wide range of VOC and inorganic pollutant emissions.
- Building on reclaimed land (brownfield sites)
- Prior to construction - highlight areas of high concentrations of air toxics and assess the effectiveness of remedial actions.
- VOC detection.
- Environmental management
- Assess the impacts of air pollution on forests.
- Monitor emissions from natural phenomena such as volcanoes
Indoor Air Sampling
- Industrial emissions
- Emissions from chemical, cleaning, industrial and manufacturing processes.
- Building on reclaimed land
- Migration of pollutants into the building due to insufficient remedial action.
- Personal and workplace monitoring
- Anaesthetic gases, VOCs, chemicals associated with specific work environment.
- Paints, Furnishings and Floor coverings
- Hazardous air pollutants often arise in indoor environments due to new products or from re-decorating.
- VOCs and Formaldehyde.
- BREAAM suite of tests for new buildings
- Combustion - Heating systems and Smoking
- Emissions of Nitrogen dioxide and VOCs can be monitored.
- Particulate counts are especially important for people with respiratory health problems.
- Cleaning chemicals
- Residue from dry cleaning processes.
- Sterilisation chemicals.
- Paint stripper.
- Drains
- Odours can arise due to Sulphur dioxide, Acid gases and Ammonia pollutants.
- Museums and libraries
- Hazardous gases may damage valuable artefacts.
- VOCs (including Acetic Acid), Ozone, Sulphur dioxide, Ammonia, Hydrogen sulphide, Formaldehyde and Nitrogen dioxide.
- Migration of pollution from attached garages into homes
- Vehicle emissions, fumes from stored paint, fuel, solvents, etc.
- VOC monitoring, Nitrogen dioxide, Particulates.
