Insights Wales – Air Quality Monitoring

Dr Leshan Uggalla

Outdoor air quality has a significant impact on public health and the environment. Exposure to air pollution can cause a range of respiratory and cardiovascular health issues, including asthma, lung cancer, and heart disease. Poor air quality can also have a negative impact on crop yields and natural ecosystems.

A team at USW developed a low-cost, long-life and accurate air quality monitoring network in collaboration with the Welsh government, Rhonda Cynon Taff (RCT) borough council, Welsh Institue for Digital Information (WIDI) and Respiratory Innovations Wales (RIW) that could change the way authorities react to the challenges caused by air pollution. These systems are essential because they can provide real-time data on pollution levels in areas where traditional monitoring systems may not be available. This can help individuals and communities make informed decisions about outdoor activities and reduce exposure to harmful pollutants. Additionally, low-cost platforms can be deployed on a larger scale, providing a more comprehensive picture of air quality across a region or city.

The team’s collaborative work was short-listed for the IET (Institute for Engineering Technology) Impact in Society Awards 2023.
