Overview
- Ecologistas en Acción’s CleanCities campaign measured nitrogen dioxide around schools in several Spanish localities and found many sites above the WHO health guideline.
- Murcia posted the worst readings in the campaign, which the group links to nearby road traffic at common school drop‑off routes.
- In Cantabria, 32 centers in Santander and Torrelavega were flagged, with 16 in Santander above the WHO level yet under Spain’s legal cap of 40 micrograms per cubic meter.
- In the Basque Country, environmental groups warned about poor air at 75 school environments, fueling calls for traffic‑calming and low‑emission zones to cut exposure.
- A separate Tarragona survey by local groups found WHO exceedances at 25 of 26 schools, with peaks of 32.9 and 31.8 micrograms per cubic meter near Saavedra in Tarragona and Verge Maria del Lledó in la Pobla de Mafumet.
