Short Course Description:

This 2-session interactive ONLINE course will use Zoom. It is an introduction to ammonia as an air pollutant and its role in air quality impacts. The course will cover an overview of the sources and effects of ammonia pollution, air quality policies and legislations targeted at reducing emissions and impacts of ammonia.  The course will also explain how ammonia is measured and how to link concentrations to effects in local assessments.   

Course Objectives:

  • Understanding of ammonia as an air pollutant, including effects of ammonia on ecosystems and human health.
  • Understanding types of ammonia emissions sources.
  • Understanding UK government policies on reducing ammonia emissions and mitigating impacts.
  • Understanding of methods for measuring ammonia in ambient air.
  • Understanding of how measurements can be used in effects assessments.

Learning outcomes:

By the end of the course, you will have a basic understanding of ammonia as an air pollutant. You will also have an appreciation of how ammonia is measured and how measurement data may be used in effects assessments.

Course Leaders:

Sim Tang, UK Centre for Ecology & Hydrology.

Sim Tang is an Environmental Chemist with over 20 years’ experience and expertise in ammonia and other reactive gas and aerosol measurements (e.g. ALPHA® and DELTA®) and research. She advises on air monitoring strategies and has led projects from local (e.g. linking concentrations to effects), national (e.g. establishing the UK National Ammonia Monitoring Network, NAMN) to continent-scale networks (e.g. pan-European monitoring network on ammonia, acid gases and aerosols). As a member of the European working group on diffusive samplers (CEN/TC264/WG11), Sim has contributed to the publication of CEN standards on the determination by diffusive sampling of NO2 and NH3.

Amy Stephens, UK Centre for Ecology & Hydrology.

Amy has worked for UKCEH as an Environmental Chemist for five years.  Her research is focused on ammonia in air measurements.  Amy manages the national ammonia network as well as several projects measuring ammonia levels on sensitive ecosystems. Amy is also managing the delivery of ALPHA® and DELTA® samplers and analysis to our customers and training them on how to correctly use the systems.

Christine Braban, UK Centre for Ecology & Hydrology.

Christine Braban is the leader of the Atmospheric Composition Change Group in the Atmospheric Chemistry and Effects Science Area of UKCEH. Her research interests cover rural and urban air quality with a focus on ammonia and reactive nitrogen species, She works with long term observations and experiments, and with low and high tech instrumentation. Christine is a lead scientist for atmospheric measurements strategy at Auchencorth Moss (WMO-GAW Regional station, ICOS Ecosystem station UK EMEP Supersite and atmospheric observatory platform).

Dr Marsailidh Twigg, UK Centre for Ecology & Hydrology.

Marsailidh’ s research interests have included the measurement of concentrations and fluxes of ammonia for over 18 years. She has been involved in the development and the application of both state-of-the-art and low-cost measurement methods specifically with enabling better quantification of dry deposition processes of reactive nitrogen compounds and water soluble aerosols. Marsailidh has contributed to European Committee of Standardization working group on passive sampling of ammonia and recently led an international campaign evaluating the applicability of ammonia measurement techniques.

Netty Van Dijk, UK Centre for Ecology & Hydrology.

Netty is an environmental researcher and her main research interest is looking at the effects of nitrogen deposition on sensitive vegetation and habitats. She has over 15 years’ experience at a long term N-deposition manipulation field site as well as with several projects looking at effects from ammonia on sensitive vegetation. She is also interested in looking at early signs of damage (biomonitoring) by nitrogen.
