Research 498: Indicators of Air Pollution Effects in Ecosystems for Monitoring under the EU National Emission Reduction Commitments Directive

Authors: Thomas Cummins, Lorna Marcham and Keelan McHugh, November 2025

Year: 2025

EU member states are required to continuously monitor the state of ecosystems where negative effects of air pollution may occur, under the National Emission Commitments Directive (NEC). The NEC Indicators project led by a team in UCD reviewed indicators used to detect air pollution effects in sensitive ecosystems like bogs and semi-natural grasslands. It focused on ammonia, mainly from agriculture, and ozone, formed through chemical reactions involving industrial and transport emissions. The findings show that ozone levels are highest near Ireland’s Atlantic coast, decreasing inland and in urban areas due to deposition and chemical reactions. Researchers found that even low nitrogen inputs can significantly alter plant communities. The findings may be used to review and refine monitoring methods in the National Ecosystems Monitoring Network. Development of structures and communication within the monitoring community is encouraged.

Research 497: Understanding Ozone Levels in Ireland

Authors: Liz Coleman, Nikhil Korhale, Damien Martin, Emmanuel Chevassus, Ling Zhen, Wei Xu and Colin D. O’Dowd, November 2025

Year: 2025

Ozone plays a crucial role in atmospheric chemistry, forming naturally in the stratosphere and at ground level through sunlight and precursor pollutants. While essential, ground-level ozone poses risks to human health and ecosystems. A University of Galway-led study explored the drivers of ozone pollution in Ireland, highlighting the influence of meteorology and transboundary emissions. Using long-term data and advanced modelling, researchers found that rural and coastal areas experience higher ozone levels than urban zones, though urban ozone is rising in Ireland and at a Global level due to declining NOₓ emissions. The study identifies methane as the main reactive carbon precursor to Irish ground-level ozone. The findings provide policy actors with evidence that supports the use of high-resolution modelling to understand ozone trends and recommends increased public awareness using educational campaigns.
