Global Air Quality Initiatives: IQAir's Impactful Partnerships and Advocacy Efforts

At the core of IQAir's mission lies a powerful belief: every local effort to enhance air quality can set off a chain reaction of benefits across the globe. It's a mission that drives us to forge transformative partnerships with air quality advocates worldwide, uniting in a common quest for cleaner air. 

Our partnerships span continents, bringing together a diverse coalition of stakeholders — from grassroots activists in bustling cities to innovators in quiet communities. These diverse collaborations enable us to extend our reach far beyond individual efforts. 

The 2023 IQAir World Air Quality Report: A Call to Broaden Global Air Quality Monitoring

The 2023 IQAir World Air Quality Report reveals a disparity in access to crucial air quality data, particularly in developing countries, where the scarcity of monitoring infrastructure leaves populations vulnerable to the unseen dangers of polluted air. 

Leveraging data from low-cost sensors alongside traditional air quality monitoring stations, the report not only highlights these severe disparities in air pollution exposure and data but also serves as a call to action for the international community to expand and enhance air quality monitoring networks.

Can we set performance targets for low cost sensors?

Presented byJohn Saffell, Alphasesne Ltd.

Summary: Air quality (AQ) networks and personal monitors using low cost sensors are generating results at a rapidly expanding rate. But can these results be accepted as valid measurements? We can rephrase this question: do air quality sensors and sensor systems meet their performance targets?

Air quality data analysis: life after r2

Presented byJohn Saffell, Alphasesne Ltd.

Summary: Air quality (AQ) is increasingly being measured using high density, low cost sensor networks, rather than low density, equivalent or transfer standard monitoring stations.  The next step for these AQ networks is improving sensor performance so that data analysis is more robust.   

Source characterisation and emission indices estimation using hyperlocal measurements from a low-cost sensor network - London Heathrow airport

Presented ByLekan Popoola, University of Cambridge

Description: Low cost sensors are becoming increasingly available for studying urban air quality. By making hyperlocal air quality measurements at high time resolution, this technique can be used in identifying pollution sources. When coupled with CO2 measurements, real world emission indices can be estimated. 

Public Institutions and Trust: Developing Community Data Assets

Presented ByAngela Eaton, Safecast

Summary: Safecast believes that people make better health and living decisions when individuals self-generate and publicly share environmental data. As a community-contributed data platform, Safecast emphasizes raw data, transparent collection, air quality standards that allow data sets to be used in combination, and free data access to provide the greatest relevance to communities and individuals. 

Web Tools for Sensor Data

Presented byGraeme Carvlin, Puget Sound Clean Air Agency

Summary: At the Puget Sound Clean Air Agency, one of our main goals is to characterize and communicate air quality with the active participation of the public. Lower cost air sensors are now a large part of that discussion and we are interested in communicating their benefits, drawbacks, and how to use them to get meaningful data.

World Air Quality Report 2022 finds only six countries met WHO guidelines for PM2.5

Following the 5th annual IQAir report, only Australia, Estonia, Finland, Grenada, Iceland, and New Zealand have met WHO's guideline for PM2.5. This is concerning as 126 other countries failed to meet this guideline, making one wonder what can be done to combat this.

Poor spread of air quality monitoring stations could suggest why information is not equally distributed. Despite there being 30,000 stations, 

Kitchen air pollution tackled in University of Surrey’s Global Centre for Clean Air Research

Recent studies have shown that the fumes from cooking meals causes poor indoor air quality, increasing associated health risks. However, the University of Surrey's Global Centre for Clean Air Research (GCARE) has come up some simple but effective solutions.

For example, opening a window, steaming rather than frying, and keeping those who aren’t actively cooking out of the kitchen can protect people from inhaling harmful toxins."

Air pollution hospitalises 200,000 in one week as fumes, emissions and smoke descend on Thailand

The air quality of Thailand's major cities has reached a point that more people are dying from air pollution than obesity or smoking. In fact, 

According to the WHO’s State of Global Air report, air pollution accounted for nearly 8% of all deaths (more than 41,000 cases) in Thailand in 2019, with PM2.5 ranked as the top risk for such deaths.

Upcoming Conferences

ASIC, Ghana

Air quality monitoring using smaller low cost sensors is continuously growing around the world. With support from the Clean Air Fund, the ASIC International Connection Hub Series has supported the connections of researchers and communities around the world. Bringing ASIC to Bangalore, India in August 2022 in partnership with CSTEP and the India Clean Air Summit was an wonderful opportunity that allowed us to build an in-person discussion between 100 researchers, regulators and community members about low cost sensor use within the country.

Applying Research Internationally

Reviewing ASIC, Pasadena Presentations

This Fall we are hosting a series of webinars that are focused on in-depth discussions of presentations offered at the 2022 ASIC, Pasadena event in May. We have invited the authors and lead speakers of the presentations to join us for a longer 45-minute question-and-answer session. Our aim is to highlight discussions that will aid in further developing upon the conversations hosted in Bangalore, India this past August.

Better Data for Cleaner Air – A New Paradigm in Air Quality Monitoring

For decades, air quality measurements have been synonymous with measuring PM2.5 and PM10, combined weight of particles of size 2.5 and 10 microns, driven by the US EPA and other governmental bodies around the world. While PM2.5 and PM10 do an adequate job of representing outdoor air quality, it paints a woefully incomplete picture when measuring indoor air quality.

Air Pollution and SARS Mortality

How Air Pollution May Affect SARS Mortality

Reviewing publicly available data, researchers assessed SARS morbidity and mortality in relation to air pollution through air pollution index (API). Through this data, researchers analyzed the relationship between air quality and SARS mortality rate. 

Ecologic analysis conducted among 5 regions with 100 or more SARS cases showed that case fatality rate increased with the increment of API (case fatality = - 0.063 + 0.001 * API).

How Long-term Exposure to Air Pollution Increases Risk of Dementia

Long-term Exposure to Air Pollution Increases Risk of Dementia

Recently published research in the journal JAMA of Neurology has found that long-term exposure to air pollution results in an increased risk of dementia. 

Following 364 individuals for 11 years, aged 74 and older, living in central Stockholm Sweden, the research suggests that dementia may become a major issue as more of the population moves to highly polluted areas,

ASIC Virtual Series coming to your livingroom!

While COVID-19 has everyone all over the world staying home to shelter in place, quarantine and avoid possibly contracting the virus or spreading the virus, the air quality has been improving with people driving less and some factories shutting down. However, with loosening regulations at the US EPA and around the world due to the stay at home orders, the ASIC Technical Program Committee wants to make sure people can still monitor the air quality in their region armed with the most up to date information and knowledge from our ASIC presenters.
