DESCRIPTION:Exposure to poor air quality can have severe effects on health
  and well-being\, with children being particularly vulnerable. Apart from 
 the home\, schools are where children spend most of their time indoors. As
  such\, the Schools’ Air quality Monitoring for Health and Education (SA
 MHE) Initiative has set out to bring together teachers\, students and rese
 archers to build a national dataset of air quality in schools. Participati
 ng schools receive a free monitor that measures particulate matter (PM)\, 
 CO2 and temperature amongst other metrics.\nWe present findings from air q
 uality data collected from over 400 schools over the 2023-2024 academic ye
 ar.  By comparing PM2.5 concentrations in this data set to the outdoor PM2
 .5 concentrations as recorded by background Defra AURN stations\, we demon
 strate that the classroom PM2.5 concentration is closely linked to the out
 door concentration. Outdoor particulate matter events\, defined as short p
 eriods of elevated outdoor PM2.5 concentrations\, are evidenced within cla
 ssroom measurement\, leading to disproportionately high indoor exposure du
 ring these events.\nThese findings enhance our understanding of air qualit
 y within UK schools\, provide an evidence base for future guidance of scho
 ol building operation and ventilation\, and contribute to shaping future s
 chool design and retrofit programs.\n
