This is a now known consequence of good weather, when the weather turns to high pressure, atmospheric pollution returns to Ile de France. And this is the case this Tuesday: no or little wind, fine particles will have difficulty circulating in height. Airparif, the organization that monitors air pollution in the region, predicts an overrun of the information threshold, which is the first threshold for raising public awareness. Despite the drop in car traffic in these times of health crisis, the level of fine particles in the atmosphere will be high, and likely to bother vulnerable people.
Consequently, it is recommended to keep your car in the garage, for those who can. Telecommuting, carpooling and use of public transport are also recommended. Recommendations that could still be valid on Wednesday, Airparif will refine its forecasts on Tuesday.
