Terneuzen's air quality faces significant challenges as the Zeeland Refinery and Dow Chemical's Terneuzen complex — one of Europe's largest integrated chemical manufacturing sites — generating elevated SO₂, ethylene, and industrial PM2.5 alongside the Ghent-Terneuzen Canal's vessel traffic. The Westerschelde estuary provides ventilation on westerly winds, while the chemical complex's extraordinary scale makes Terneuzen one of the Benelux's most distinctively chemical industry-defined urban environments throughout the year.

Frequently Asked Questions

Is air quality bad in Terneuzen right now?

On 21 July 2026, overall air quality in Terneuzen is fair. O3 is the main pollutant at 26.7/100. Pollution peaks around 6:00 AM (NO2: 43.1/100).

Will air quality be worse tomorrow in Terneuzen?

On 22 July 2026, air quality conditions in Terneuzen will be similar to today, with AQI forecast at fair at 34.0/100. Pollution peaks around 5:00 AM (NO2: 34.0/100).

When is air pollution at its worst in Terneuzen?

Keep an eye on Terneuzen during the birch, oak, and alder pollen peak during spring and the start of summer, and on calm, hot days when traffic and local industry emissions accumulate; the exposed delta setting rarely lets pollutants linger for long. The calmer months in between generally keep Terneuzen close to typical Dutch air quality levels.

Are air quality levels in Terneuzen based on measurements or forecasts?

It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.

Why doesn’t the forecast always reflect wildfire impacts?

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
