Project: Metrology for ammonia in ambient air
Ammonia contributes to problems such as eutrophication and acidification of land and water, leading to a reduction in soil and water quality, harm to animals and plants, and changes to the ecosystem. In humans it is associated with a high incidence of heart and lung diseases. Ammonia emissions are estimated to have doubled across Europe over the last 100 years due to changing industrial and agricultural practices such as the use of urea-based fertilisers. While regulations are in place to limit ammonia emissions, there is a lack of guidance regarding the measurement techniques and analysis that should be used to obtain the emissions data. This project will develop traceable measurements of ammonia in air and provide standards for the measurement of ammonia concentrations under ambient conditions. Validated high quality ammonia measurement data will help identify changes caused by environmental protection policies and provide independent verification of atmospheric models.
