During the New Years period, many cities in the Netherlands experienced a short period of smog caused by fine particulate matter. This is based on measurement data collected by the RIVM. The smog was caused by the large amount of fireworks set off during the New Years celebrations, resulting in very poor air quality in several locations for a short time.

The highest concentration of fine particulate matter measured at city stations of the national air quality monitoring network was in Utrecht (1848 micrograms of fine particulate matter per cubic meter of air). These are preliminary measurement values. The RIVM checks the quality of the measurements afterwards. Changes in the measurement values may occur as a result. 

The peak concentrations are higher than the previous New Years period. The wind was less strong, resulting in a higher concentration of fine particulate matter in the air. Furthermore, more fireworks were sold, which may also contribute to higher concentrations. 

Due to the wind, concentrations quickly dropped to the levels before the fireworks.

Fine particulate matter can lead to health complaints

Fireworks can cause a high concentration of fine particulate matter in the air. Together with other pollutants, this can lead to a decrease in lung function. Respiratory complaints such as wheezing, coughing, and shortness of breath may increase. Especially people with lung diseases such as asthma, chronic bronchitis, or emphysema, and people with cardiovascular diseases may be affected.

Samen Meten

Many citizens measure fine particulate matter themselves and share the results with the RIVM. The RIVM also collected these measurements around the New Years period this year. The first results will soon be available on the Samen Meten (external link) website.
