Carbon Monoxide: The Silent Killer Lurking Indoors

Sotirios PapathanasiouLeave a comment

Carbon monoxide (CO), often referred to as the “silent killer,” is a colorless, odorless, and tasteless gas that can be deadly when inhaled in high concentrations. While it is often associated with outdoor air pollution, CO can also pose a significant risk within our homes and workplaces.

Furthermore, while carbon monoxide is often associated with acute poisoning, leading to immediate symptoms like headaches, dizziness, and nausea (hence we have CO alarms), it can also have long-term health consequences. Even exposure to low levels of CO over extended periods can cause damage to various organs and systems. Chronic CO exposure has been linked to chronic fatigue, memory problems, work difficulties, sleep disorders, dizziness, neurological disorders, paresthesia, recurrent infections, abdominal pain, and diarrhea 1, 2.

Global Coalition Launches Initiative to Establish Universal Indoor Air Quality Standards: Global Open Air Quality Standards (GO AQS)

Sotirios Papathanasiou2 Comments

A diverse global coalition of scientists, air quality experts, and industry leaders has united to establish the Global Open Air Quality Standards (GO AQS), an unprecedented initiative aimed at creating universal indoor air quality (IAQ) standards. This groundbreaking effort seeks to ensure that everyone, regardless of location or socio-economic status, has access to the knowledge and tools needed to enhance their health and well-being through improved air quality.

GO AQS will serve as an authoritative and comprehensive resource for scientists, engineers, public health officials, businesses, and policymakers worldwide. By providing accessible, consistent and clear, standardised guidelines for IAQ, it empowers people to make informed decisions about their living and working environments, directly impacting health and productivity.

IAQ significantly affects our health, cognitive function, and overall productivity. Poor indoor air can exacerbate respiratory conditions, increase the risk of cardiovascular problems, and contribute to reduced work performance. Establishing universal air quality standards is a critical step in ensuring equitable access to clean and healthy air globally.

The coalition comprises experts from different fields including public health, environmental science, epidemiology, occupational health, engineering, and air quality research. Together, they are dedicated to developing GO AQS standards that are both scientifically robust and practical for implementation across diverse settings. These standards will address a wide range of indoor pollutants, including particulate matter (PM and PCN), carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), and formaldehyde (CH2O), which are known to have significant adverse effects on human health and environment.

GO AQS aims to be a valuable tool for the public, private sector, and academia alike. Organisations that adopt these standards can enhance the health and well-being of their employees and customers, while simultaneously reducing their environmental footprint. This initiative also supports broader sustainability goals by promoting healthier indoor environments. 

While air quality interrogators and manufacturers are supportive of the overall goals of GO AQS, there are areas where the draft version requires further refinement to ensure its practical implementation. We remain committed to working collaboratively with all stakeholders to finalise a version of GO AQS that is both effective and feasible for the industry. Therefore the coalition is currently finalising the GO AQS standards and developing educational materials to facilitate their global implementation. The official launch is anticipated in December 2024, marking a significant milestone in the global effort to prioritise IAQ.

Help Us Breathe Cleaner Air: Citizen Science Project Seeks Donations for Wood Smoke Research

Sotirios PapathanasiouLeave a comment

I won’t write a long introduction because this is of urgent matter for people to understand and support. While wood-burning stoves offer a tempting escape from soaring energy costs, they also release harmful substances into our homes and communities. These include fine particulate matter (PM2.5) and Polycyclic Aromatic Hydrocarbons (PAHs), both of which have been linked to serious health issues, including cancer.

Unveiling the Hidden Danger

Despite the known risks, we still lack sufficient data on PAHs concentrations in residential areas where wood burning is common. The location of investigation will be chosen in the Netherlands or Belgium. This is where your help is crucial.

By supporting this citizen science project, you’ll help us gather vital information about the impact of wood smoke on our air quality. The project will measure PAHs and PM2.5 levels in a residential area heavily reliant on wood burning for heating. This data will be invaluable for raising awareness among policymakers and advocating for stronger air quality regulations.

How Your Donation Makes a Difference

Analyzing air for PAHs is a complex process requiring specialized equipment and laboratory analysis. With your support, the project will:

  • Purchase air pumps and ten (10) absorption tubes to collect air samples.
  • Conduct laboratory analysis to identify and quantify PAHs.
  • Measure PM2.5 levels using advanced sensors.
  • Compare PAHs levels in wood-burning areas to background levels.

Join the Fight for Clean Air

Your donation will directly contribute to a healthier community. Together, we can uncover the hidden dangers of wood smoke and work towards cleaner air for everyone. Finally, I want to thank Dieter Pientka for his passion to investigate this crucial subject.

Help us make a difference. Donate today!

Indoor Environmental Quality and Radiation Exposure

Sotirios Papathanasiou1 Comment

While we often think about indoor pollutants such as particle pollution (PM2.5), Carbon Dioxide (CO2), etc, the quality of the indoor environments (IEQ) can also have a significant impact on our health through various sources of radiation exposure within our homes and workplaces. Radiation is not commonly investigated nor monitored indoors.

Beyond the Usual Suspects:

Let’s explore some unexpected sources:

  • Frequent Flyers: Cosmic radiation exposure increases with altitude. While infrequent flights pose minimal risk, frequent flyers may experience slightly elevated radiation levels.
  • Ground Elements: Radioactive elements like uranium naturally occur in soil and rocks. Depending on the geology of your area, these elements can seep into basements or crawlspaces, releasing radon gas, a known human carcinogen. Radon forms from the breakdown of uranium, radium, and thorium, which are naturally present in rocks, soil, and water. As radon gas seeps into buildings through cracks and gaps in foundations, it can accumulate to dangerous levels.
  • Vintage Timekeepers: Those vintage watches with luminous dials might be harboring a radioactive secret. Radium or tritium, once used for illumination, can pose a health risk.
  • Colorful Contaminants: Certain ceramics and glassware use glazes containing radioactive elements for vibrant colors. While generally “safe” when intact, chipping or breaking these items can release radioactive particles.
  • Food: Bananas, spinach, oranges, beer, etc. all contain potassium K-40 which is a radioactive isotope that emits beta and gamma radiation. The dose of radioactivity they deliver is tiny and does not pose a health risk.
  • Nuclear Power Plants: Nuclear power plants are heavily regulated and emit very low levels of radiation during normal operation. While unlikely, a serious accident at a nuclear power plant could release dangerous amounts of radiation.
  • War Zones: Radiation exposure is a serious danger in a war zone if a nuclear weapon is detonated.

Can an Air Expert Escape Air Pollution? A 2-Month, 6-Month, and Year-Long Experiment in Personal Air Quality

Sotirios Papathanasiou3 Comments

Air pollution is an invisible threat, silently impacting our health. But what if you knew exactly where it lurked, both indoors and outdoors? Could an air quality expert, armed with this knowledge and personal equipment, achieve the World Health Organization’s (WHO) air quality guidelines for extended periods?

This is the question I, Sotirios Papathanasiou, an air quality expert,  will try to figure out over the next year. Starting July 1st, 2024, I embarked on a unique experiment, tracking my personal air quality for a full year. I am monitoring two key air quality metrics: Carbon Dioxide (CO2) and PM2.5 (fine particulate matter). However, PM2.5 data will be excluded when relative humidity surpasses 70% because the limitations of low-cost sensors. I will be carrying an Atmotube Pro and an AIRVALENT everywhere I go.

I am your human guinea pig, carrying these portable air quality monitors everywhere – from my bedroom to my gym, from my kitchen while cooking to the beach on a weekend getaway. This comprehensive data will allow us to see if, despite my expertise in pollution sources and protective measures, I can consistently meet the WHO’s air quality guidelines.

Don’t Be Fooled by Mass: Why Counting Particles Is One Way Street for Sub-micron Air Quality Monitoring

Sotirios PapathanasiouLeave a comment

While monitoring air quality, scientists traditionally relied on mass concentration to measure particulate matter (PM). This metric tells you the total mass of particles per unit volume of air. But for sub-micron particles – those less than one micrometer in diameter – mass concentration falls short. Here’s why measuring particle number by size distribution is a superior approach.

The Small Matter of Small Particles

Sub-micron particles are incredibly tiny. Imagine a human hair – typically around 70 microns thick. A sub-micron particle is hundreds to thousands of times smaller! Due to their miniscule mass, even large numbers of sub-micron particles can register a low mass concentration. This can be misleading, as the health risks they pose aren’t dependent solely on weight.

Penetrating Deep: Size Matters More

Sub-micron particles, especially those in the ultrafine range (less than 100 nanometers), are deeply concerning. Their small size allows them to bypass the body’s natural defenses and infiltrate deep into the lungs. These particles can even enter the bloodstream, potentially causing respiratory and cardiovascular problems.
