CRAC research brings ease for Allergy sufferers

Under the title of 'Pollen Analysis takes Flight' the Irish Times‌ today published research undertaken by Prof. John Sodeau, Dr. David Healy and Dr. David O'Connell in the Centre for Research into Atmospheric Chemistry (CRAC).

The Environmental Protection agency, An Ghníomhaireacht um Chaomhnú Comhshaoil, EPA, published this research with the title:

'Novel air monitoring approach could ease suffering for allergy sufferers'

4th February 2013: The Environmental Protection Agency (EPA) has published major new research 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.

Commenting on the release of the research report Dara Lynott EPA Director said,

 “The environment and health are intrinsically linked and this innovative research project shows how state of the art instrumentation can be used to help protect both.  The novel application of technology could help people who suffer from respiratory issues to 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 report 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).

Professor John Sodeau, University College Cork (UCC),
principal investigator on the project said,

“Many airborne biological particles are known to impact adversely on our health.
Pollen, fungal spores and certain bacteria are often culprits in symptoms
presenting in persons sensitive to hay fever or respiratory diseases including
asthma. Ireland currently makes no pollen count measurements of its own but our
near real-time approach could make this task considerably easier. ” 

This research was conducted in the Centre for Research Atmospheric Chemistry (CRAC) in University
College Cork and was funded by the EPA’s Climate Change Research Programme. The
full report, A new approach to Bioaerosol Monitoring in Ireland, is now
available on the EPA website at www.epa.ie/downloads/pubs/research/climate/.
