Ormantine - Ammonia Rapid Air Monitor (RAM)
Ammonia diffusion tubes are suitable for long-term monitoring of ambient Ammonia pollution (sampling times are 2-4 weeks). These samplers are simple to use, requiring no specialist skills or power supply, making them an efficient monitoring option. With very low detection limits (in the low parts per billion range), even low levels of Ammonia pollution can be identified.
Sources of Ammonia in ambient air:
- Decaying organic matter – e.g. sewage.
- Agriculture – particularly cattle, pig and poultry farms, application of slurry.
- Manufacturing – plastics, pharmaceuticals, rubber, petrochemicals.
- Industrial and combustion processes.
- Catalytic converters.
Potential implications Ammonia pollution:
- Unpleasant odor.
- Damage to vegetation.
- Soil acidification.
- Conservation areas are at risk of Ammonia deposition – heathland, moorland, bogs – pollution may cause a change in plant species.
