Abstract A pilot study was performed to investigate whether the application of a new mechanical ventilation system with a fine F8 (MERV14) filter could improve indoor air quality in a high school near the Amsterdam ring road. PM10, PM2.5, and black carbon (BC) concentrations were measured continuously inside an occupied intervention classroom and outside the school during three sampling periods in the winter of 2013/2014. Initially, 3 weeks of baseline measurements were performed, with the existing ventilation system and normal ventilation habits. Next, an intervention study was performed. A new ventilation system was installed in the classroom, and measurements were performed during 8 school weeks, in alternating 2-week periods with and without the filter in the ventilation system under otherwise identical ventilation conditions. Indoor/outdoor ratios measured during the weeks with filter were
compared with those measured without filter to evaluate the ability of the F8 filter to improve indoor air quality. During teaching hours, the filter reduced BC exposure by, on average, 36%. For PM10 and PM2.5, a reduction of 34% and 30% was found, respectively. This implies that application of a fine filter can reduce the exposure of schoolchildren to traffic exhaust at hot spot locations by
about one-third.

Join us for an interview with Dr. Peter Rowe, Professor of Pediatrics and Director of the Children's Centre Chronic Fatigue Clinic at Johns Hopkins University as he gives us new hope for the treatment of Long COVID in Children. He explains that because of the parallels between ME/CFS and Long COVID in children, his 30 years of researched treatments for ME/CFS can be used to help children with Long COVID now while we are waiting for RCT ( randomized clinical trials) to occur.
Please join us for the POP BC live briefing on Long COVID: A Mass Disabling Event on Wednesday, October 30th at 1 pm as we discuss the important topic of Long COVID with Kayli Jamieson and Connie Chan, Long COVID survivors, and Dr. Ric Arseneau, Internal Medicine Specialist and Long COVID Physician and Director of one of the clinics treating Long COVID in BC.
As we start a new school year, clean air in schools is a vital issue not only because of the health effects from the ongoing COVID-19 pandemic and air pollution, but because of the direct link to the ability of children to learn. Hear about the new recommendations for Indoor Air Quality in Schools and Childcare Facilities from Vancouver Coastal Health and Fraser Health.
