The Role of AirNodes in Groundbreaking eDNA Research

AirScape’s AirNode sensors, primarily designed to measure air pollution, were used in a groundbreaking study that has significantly broadened their application. This research demonstrated that environmental DNA (eDNA), the genetic material shed by organisms into their surrounding environment, is not just found in water or soil – it’s also in the air around us.

In the study, “Detection of airborne vertebrate eDNA: Applications for aerobiology and monitoring”, researchers including our CSO, Matthew Johnson, found atmospheric eDNA from various animal species, reshaping our understanding of ecological monitoring. Traditionally, studying biodiversity often requires labour-intensive surveys and, sometimes, invasive physical trapping of species. However, this study shows that eDNA research can provide a non-invasive, efficient, and comprehensive alternative.

AirNode sensors were used to collect, filter, and analyse airborne eDNA. By capturing microscopic particles from sources like skin cells, hair, and pollen, the researchers could match the resulting genetic codes to an extensive database of known sequences from different species. This process identified a wide range of local vertebrate taxa without visual confirmation or physical trapping, offering a non-invasive and efficient way to monitor biodiversity.

And the story doesn’t end there. Our AirNode sensors could detect hard-to-find species, such as those living in dry environments, burrows, caves, or flying beyond the range of wildlife cameras. This dramatically expands the reach of ecological studies and shows that our AirNode sensors can provide insights beyond just air pollution.

Challenges remain, such as understanding the travel distance of eDNA, deciphering how animals shed DNA, and preventing contamination. However, looking back at this revolutionary study, we’re excited about the future of biodiversity monitoring. It’s clear that the potential of AirNode sensors extends far beyond measuring air pollution – the secrets of biodiversity are literally in the air!

Our latest report analyses the air quality in Camden, London, during June 2023. This comprehensive study, which involved data from 80 sensor nodes, underscores concerns about PM2.5, O3, and NO2 pollution levels in the borough.

Perhaps the most striking revelation in this report is the persistent breach of the World Health Organization’s guidelines for NO2, especially in areas with heavy traffic. The data demonstrate a direct correlation between heightened NO2 levels and increased temperatures, indicating a pressing need for the implementation of effective pollution control measures.

The report also indicates a surge in O3 concentrations during June, indicating the link to prolonged periods of sunshine and higher temperatures. Notably, between the 10th and 18th June, O3 levels noticeably increased and triggered a city-wide high pollution alert.

Additionally, PM2.5 levels elicited concerns, with the report noting significant surges on specific days in June. Localised pollution hotspots were observed in High Holborn, Fitzjohn’s Ave, and North End Way.

Given the overall rise in Camden’s Air Quality Index (AQI) during June, AirScape’s street-level air quality data in real time empowers immediate and strategic action to improve the area’s air quality.

Clean air, like clean water and uncontaminated food, is a fundamental human necessity. But how often do we pause to consider the quality of the air we breathe? According to the World Health Organization, nine out of ten of us breathe air that exceeds their safety guidelines. This invisible threat poses severe risks to our health and the environment.

Understanding Air Pollution

Air pollution is the presence of substances in the air that can cause harm or discomfort to humans, animals, or the environment. These pollutants can be either natural (like volcanic ash or pollen) or man-made (like vehicle emissions or industrial waste).

The main types of air pollution include particulate matter, ground-level ozone, and nitrogen dioxide. Our latest AirNodeTM can measure up to seven pollutants:

PM2.5 (Fine Particulate Matter): These are extremely small particles, often described as fine dust, with a diameter of 2.5 µm or smaller. Because of their small size, PM2.5 particles can travel deep into the human respiratory system, reaching the lungs and even entering the bloodstream. Long-term exposure can lead to serious health issues like heart disease, respiratory problems, and even premature death.

PM10 (Coarse Particulate Matter): PM10 refers to particles with a diameter of up to 10 µm. While larger than PM2.5, these particles can still be inhaled and cause health problems. PM10 often originates from sources like road dust, crushing and grinding operations, and certain agricultural activities.

NO2 (Nitrogen Dioxide): This is a reddish-brown gas with a sharp, acrid smell. Nitrogen dioxide primarily gets in the air from burning fossil fuels. It contributes to the formation of smog and can exacerbate respiratory conditions, particularly asthma.

O3 (Ozone): In the upper atmosphere, ozone is beneficial by protecting us from harmful sun rays. However, ground-level ozone (tropospheric ozone) is a harmful pollutant. It is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds in the presence of sunlight. Breathing ozone can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as asthma.

CO (Carbon Monoxide): This is a colourless, odourless gas that is harmful when inhaled in large amounts. The greatest sources of CO to outdoor air are cars, trucks, and other vehicles or machinery that burn fossil fuels. High levels of carbon monoxide can be fatal.

SO2 (Sulphur Dioxide): Another colourless gas with a strong, unpleasant smell. It is produced from burning fossil fuels, especially in power plants and industrial processes that use coal or oil. SO2 can harm the human respiratory system and make breathing difficult. It’s also a contributor to the formation of acid rain.

HC (HydroCarbons): These are organic compounds consisting entirely of hydrogen and carbon. They can be emitted naturally (e.g., from plant life) and due to human activities (e.g., burning fossil fuels). Some hydrocarbons are volatile organic compounds (VOCs), which can react with NOx and sunlight to form ground-level ozone, a key component of smog.

Each of these pollutants poses a unique threat to our health and environment. By tracking these pollutants, AirScape provides valuable data for individuals, businesses, and governments to make informed decisions, promoting cleaner, healthier, and more sustainable urban environments.

The impacts of air pollution are wide-ranging and significant.

On a health level, pollutants can cause or exacerbate conditions like asthma, lung disease, and heart disease. Long-term exposure can even lead to premature death. Vulnerable people such as the elderly, children, and those with pre-existing health conditions are particularly at risk.

The environment is also severely affected by air pollution. Acid rain, caused by sulphur dioxide and nitrogen dioxide, can harm vegetation and aquatic ecosystems. Ground-level ozone can damage crops and other vegetation, reducing agricultural productivity. Air pollution also plays a significant role in climate change.

You can’t manage what you can’t measure.

The invisible threat of air pollution is a shared responsibility, one that demands our immediate attention and action.

Street-level, air quality data in real time, enables everyone to understand, manage, and ultimately reduce air pollution. AirScape brings visibility to the invisible, allowing you to identify problem areas, deploy targeted interventions, and measure their effectiveness. This detailed insight supports informed decision-making and empowers you to improve the air quality in your community.

We believe that clean air is a human right, and a vital aspect of community health and wellbeing. Every breath of fresh air counts towards a healthier and more sustainable planet.

In the continual pursuit of improving urban air quality, our most recent Pollution Events Report provides an in-depth analysis of pollution patterns in Camden, London, during April 2023. The report, authored by Szymon Kwiatkowski, uses data gathered from a network of AirNodes sensors distributed throughout the city, shedding light on the dynamics of key pollutants, PM2.5, O3, and NO2, in correlation with various weather conditions.

A Consistent Portrait: NO2

The examination of NO2 data reveals a consistent daily pattern of pollutant formation with minimal variation in average monthly concentrations. A key finding is the direct correlation between rising NO2 levels and declining temperatures as well as slower wind speeds. It also indicates that the highest NO2 concentrations are closely linked to lower temperatures.

The average NO2 concentration in April significantly exceeded the World Health Organization’s guidelines for a 24-hour NO2 average. This pattern, persisting since the start of the year, underlines the urgent need for strategies to further reduce NO2 emissions in Camden.

The Ozone Story

The O3 concentrations in April showed a more pronounced change compared to NO2. The report shows a progressive increase in average O3 concentrations over the period from February to April, likely due to extended periods of sunshine. Interestingly, O3 concentration is shown to decrease during periods of low wind speeds and winds from the north, pointing to the significant influence of wind conditions on O3 concentrations.

Spikes in PM2.5

The PM2.5 data unveils an overall increase in its average concentration in April as compared to March, albeit still lower than those recorded in winter months. Particularly interesting are the localised spikes seen around Drury Lane and High Holborn, which experienced more frequent incidents of elevated PM pollution. These observations emphasise the significance of hyper-local monitoring to inform targeted mitigation efforts.

Air Quality Index (AQI): A Measure of Progress

The AQI levels in April, reflective of the overall pollution load, were higher. This aligns with the sequential monthly increases observed across all the pollutants, underlining the necessity of sustained and proactive measures for improving air quality.

Conclusion: Informed Actions for Sustainable Cities

As the latest in a series of monthly reports, the Camden Pollution Events Report underscores the power of consistent, detailed monitoring in understanding and addressing urban air pollution. The clear correlations established between pollutant concentrations, hyper-local events, regional pollution and weather conditions offer a data-driven path towards effective interventions.

With this level of granular data, air quality city officials are equipped to make informed decisions and strategies. This highlights the invaluable role of technology and meticulous data analysis in our shared journey towards cleaner, healthier, and more sustainable urban spaces.

As Singapore is set to host talks from June 7 to 8 with Asean members Brunei, Indonesia, Malaysia and Thailand, environmental experts are planning a second roadmap focussing on strategies towards attaining a haze-free South-east Asia.

This comes at a critical time, given the expected drier weather conditions and the potential onset of the warmer El Nino weather phenomenon in the coming months.

Associate Professor Helena Varkkey from the Department of International and Strategic Studies at Universiti Malaya, believes that creating a common air quality index is a significant step forward. This will allow for a uniform measure of air quality across the region, eliminating discrepancies and confusion resulting from various countries using different indices.

Currently, different nations in the region use unique air quality index systems. Singapore uses the Pollutant Standards Index (PSI), Malaysia uses the Air Pollution Index (API), and Thailand uses the Air Quality Index (AQI). These variations make it challenging to compare air quality data effectively across the region.

The proposed second roadmap for transboundary haze cooperation aims to address this issue and further emphasises the need for coordinated efforts and measurable indicators of progress.

At, we understand the critical need for real-time, street-level air quality data for truly actionable insights. We stand in solidarity with these efforts to standardise the method of tracking air quality across South-East Asia. It’s essential for the implementation of effective measures and policies to mitigate air pollution and promote a healthier living environment for all inhabitants of the region.
