Particulate matter approach for greater health gains
Exposure to particulate matter can have serious consequences, including respiratory diseases and the aggravation of cardiovascular diseases. In the Netherlands, 9,000 people die prematurely every year due to exposure to particulate matter. If we want to win the battle against particulate matter and permanently improve air quality in the Netherlands, a different approach is needed. Based on a new view, which assumes that one particulate has more impact on health than another, we have developed a 5-step plan.

Current particulate matter approach and the clean air agreement
In the Clean Air Agreement, the national government, provinces, and a large number of municipalities strive for health gains of at least 50% by 2030 compared to 2016. The particulate matter standard and the measurements we use in the Netherlands and Europe only focus on particulate matter mass: all particulate matter smaller than 10 micron in a cubic metre of air.
Standard achieved, problem unsolved
Successful policies have reduced the concentration of particulate matter, but in recent years the reduction has stagnated, and we are achieving fewer and fewer health gains. Moreover, the composition of the particulate matter mixture is gradually changing. Policies aimed at health gains require a different, even more effective, approach.
The variables that really matter for further health gains are not included at the moment. If the particulate matter standard is met, this does not eliminate the health risks. Meeting the standard does not necessarily mean being safe.
Better differentiation leads to more heath gains
Not all particulates have the same health impact. We should also look at:
- Ultrafine particulate matter: the very small light particles that penetrate deeper into the lungs.
- Their shape and chemical reactivity; because the composition of particulate matter, and therefore its harmfulness, is not always the same.
- The source of the particulates: For example, inhaling sea salt particles while walking on the beach has a different effect than cycling behind a diesel car.
New vision for dealing with particulate matter in the Netherlands
In the fight against health damage caused by particulate matter, it makes little sense to measure only particulate matter mass, as is currently the case. At TNO, we are therefore arguing for a new particulate matter approach that is better addresses the health risks: a source-specific approach to particulate matter.
We will achieve the greatest health gains if we base our policies on the size of the particulates, their shape, and chemical reactivity. It is important to know where these particulates are; there is no single approach that works everywhere. To make the right policy choices, we have developed a 5-step plan.

Particulate matter measurements, modelling and advice
At TNO, we are developing technology that provides insight into the harmfulness, sources, and related composition of particulate matter, helping companies and governments to take well-considered, effective measures to limit emissions.
To this end, we use the following research techniques:
- We are developing sensor technology to measure at the local level and in real time.
- We apply mathematical models to make predictions about dispersion and exposure.
In addition, we are developing a real-time, health-relevant indicator of particulate matter in European cities. Currently, we already share the source (activity and origin) of particulate matter on our TOPAS website. Our high resolution dispersion modelling helps stakeholders to choose the healthiest option, such as the healthiest cycling route to a destination.

What is nitrogen and can we control it?
At present, knowledge of nitrogen still contains many uncertainties. We can improve this by measuring more often and with new technologies. Learn more.

Measuring air quality for a healthy environment
Poor air quality causes around 80% of diseases due to environmental factors. For a healthier future, we research and measure the air quality.

Reducing air pollution and climate change is a major challenge. TNO helps companies and governments to take effective measures.
How CCU can shape the carbon transition
Carbon capture and utilisation, or CCU, is a technology that involves capturing CO2 emitted from (industrial) processes and using it to make new products. It therefore doesn’t only reduce CO2 emissions, it creates new market potential. Government and industry alike see the necessity of understanding which CCU value chains are future-proof and economically, environmentally and politically viable. The Province of Zuid-Holland wanted to know what role CCU has in the future for the province.
