A New Approach to Bioaerosol Monitoring in Ireland

Climate Change Research Programme - CCRP Report 18

Summary: This major new publication was completed by Professor John Sodeau and his research team at the Centre for Research Atmospheric Chemistry (CRAC) in University College Cork (UCC). The team used state of the art air quality instrumentation, to detect and quantify pollen, fungal spores, and bacteria that are all components of the air we breathe and are known as bio-aerosols.

This major new research project has been completed by Professor John Sodeau and his research team at the Centre for Research Atmospheric Chemistry (CRAC) in University College Cork (UCC).  The team used state of the art air quality instrumentation, to detect and quantify pollen, fungal spores, and bacteria that are all components of the air we breathe and are known as bio-aerosols.  This type of novel application of the technology could help people who suffer from respiratory issues avoid problems by knowing what is in the air and thereby minimizing airborne infections.

Dr. David Healy, lead researcher and author on the BioCheA project alongside EPA Doctoral student David O’Connor found that there were more bioaerosols in the air monitored at Killarney National Park than in urban and industrial environments during the summer. While a higher number of bio-aerosol particles would be expected in a rural setting, the research team field tested technology that allowed their detection and quantification in near real-time. Recent research findings also indicate that bioaerosols may have a more important role than previously thought in influencing climate and global hydrological cycles. Therefore this method of monitoring could allow agencies to warn people who are susceptible to respiratory disease and inform responses. 

Key elements of the reports include;
• Ireland currently makes no pollen count measurements of its own but this real-time approach could make the task considerably easier. 
• The instrumentation used in this research to detect bio-aerosols (such as pollen, fungal spores and hyphal fragments) can be employed routinely and reliably in the laboratory and field.
• In terms of the different types of spores in the air, the field results confirm the large range of types expected to be found in the air in North-West Europe during the sample time periods.
• The approach to bioaerosol measurement coupled with the novel methods of data analysis could be employed in a number of different settings both outdoors (e.g. compost/waste facilities) and indoors (e.g. hospitals).
