Smog warning issued for entire Netherlands

There is a good chance of smog in the entire Netherlands on Tuesday, public health institute RIVM warns. Those sensitive to dirty air, for example people with respiratory problems, are advised to stay inside, especially during the afternoon and early evening, RTL Nieuws reports.

"For the entire country, air quality can be bad, but the highest concentrations are expected in the east", the RIVM said. The smog will be at its worst during the afternoon and early evening.

Smog caused by ozone occurs when air pollution accumulates on sunny days with little wind. It can worsen asthma symptoms, and lead to coughing and shortness of breath. Smog can also irritate the eyes, nose and throat.
