One of the stories that resonated - "I was able to venture out for an ice cream cone with a friend this day. I don't feel comfortable eating in restaurants or going to bars like most people my age. Spring and summer are nice beaches they give me more options to spend time outdoors with fewer people around - which means I get to see the people I love more often. Even short moments like this help me feel a little more like a "normal" 24 year old again

“children have returned again to overcrowded, under-ventilated classrooms amid yet another coronavirus wave with hand sanitiser & Calpol as their only protections.

Covid is not benign in children.

In January, a review highlighted the wide-ranging impact of long-Covid on children and adolescents”

I just had the opportunity to spk to WorkSafe BC as part of their public feedback forum on the CSA Z94.4 highlighting the call for N95s in healthcare settings, and asking their support in legislation & implementation. We ALL deserve #SafeHealthCare! #MaskUp #CovidIsAirborne 🖤🤘

Should people have to wear face masks in medical facilities? Violet Affleck, the daughter of Jennifer Garner and Ben Affleck, has now advocated for the return of mask mandates to help protect the vulnerable, during a speech at a UN event in New York.

Effect of Indoor Air Quality on Respiratory Health of Children: An MPPD Model Approach - Aerosol Science and Engineering Indoor air quality (IAQ) in classrooms is a crucial factor in the growing health of children as they spend significant amounts of time in school. The present work examines indoor air quality in school classrooms, the relationship between indoor air and outdoor air, and a possible risk to children’s learning. Four IAQ parameters, particulate matter (PM2.5 and PM10), carbon dioxide (CO2), temperature, and relative humidity, are assessed using a sensor-based device. Measurements were taken inside classrooms with windows open for non-air conditioner rooms, closed for air-conditioner rooms, and on the street outside the school boundary. Results indicate the exceedance of particulate matter concentrations beyond the thresholds set by the World Health Organization (WHO). Furthermore, the mean concentration of CO2 is high for the air conditioner room, and relative humidity was identified as slightly higher for one school classroom. Employing the International Commission on Radiological Protection (ICRP) model, the research analyzes the respiratory deposition dose (RDD) of PM2.5. It evaluates associated non-carcinogenic risks using the hazard quotient (HQ). Notably, the study reveals that the HQ in all classrooms surpassed the critical value of 1, indicating an elevated risk of bronchial diseases among students. Additionally, the Multiple Path Particle Dosimetry analysis suggests a higher deposition of PM in the lungs, with a predominant occurrence within the respiratory tract, particularly notable in younger children than adolescents. It concludes that urgent interventions are needed to improve school IAQ conditions, particularly in traffic-congested areas.

TLDR?
Clean Air Has No Downside
AND
Respirable Air is Good for Everyone Who Respires

A numerical study on the optimal placement of two air purifiers for simultaneous operation in a school classroom - International Journal of Air-Conditioning and Refrigeration In educational environments such as school classrooms, indoor air quality has a significant impact on the health and learning ability of children and adolescents. This study investigates how to optimally place and operate two air purifiers in a national standard-size classroom to improve air quality uniformly and effectively. Ten cases were analyzed using computational fluid dynamics (CFD) simulations, considering various placements and airflow directions of air purifiers. The air purification performance was evaluated by monitoring changes in the concentrations of major pollutants in the classroom, including PM2.5 and CO2, and the airflow distribution and average air age index were applied to evaluate the airflow circulation. The results showed that when the air purifiers were placed symmetrically to minimize mutual discharge airflow interference, pollutant removal and airflow uniformity were maximized. Case 3, where the air purifiers were placed at opposite corners of the classroom to circulate air throughout the classroom, showed the best performance. This study provides a systematic approach and analysis results to optimize indoor air quality in classrooms and contribute to student health and learning environments.

Good to know!

AQI to Cigarettes Converter How many cigarettes did you smoke because of air pollution?

Want to compare your air quality to smoking?

Search up the AQHI (or AQI) in your area and put that number into this handy calculator 🤩

jasminedevv.github.io/AQI2cigarett...

A study by Berkeley Earth found that breathing air with a PM2.5 concentration of 22 µg/m³ for 24 hours has the same negative health effects as smoking one cigarette.

Hard to make an exact/direct comparison, but this generally holds up well. berkeleyearth.org/air-pollutio...

Do you smoke?? 👉 are you sure?...

Current air quality in many places in BC has millions of people basically smoking the equivalent to multiple cigarettes a day.
