NO2 pollution, mainly from traffic, has serious consequences for children's health, such as asthma, allergies, and cardiorespiratory or cognitive problems. School areas near high-traffic roads in València and Torrent show excessive levels of this pollutant, despite local mitigation measures.
According to data from the Clean Cities citizen science campaign, six of the nine schools in València and two of the two municipalities in l'Horta Sud that participated in the measurements exceed 25 μg/m3, the daily limit established by the WHO. In Torrent, two of the five schools measured also exceed this limit.
The centers in València that exceed the daily and annual NO2 limit are CEIP Cervantes (Extramurs neighborhood), CEIP San Juan de Ribera (L'Eixample neighborhood), CEIP Juan Manuel Montoya (Natzaret neighborhood), IES Baleares (Camins al Grau neighborhood), CEIP Antonio Machado (Rascanya neighborhood), and Centro Educativo Misericordia (L'Olivereta neighborhood). All are near ring roads or arterial roads with intense traffic. CEIP Juan Manuel Montoya is also adjacent to the Port of València, a significant source of emissions.
In Torrent, CEIP El Molí and Juan XXIII show the highest values, located near roads with high intensity of combustion vehicles. CEIP El Molí is close to the Ronda del Safranar, a high-traffic road connecting Torrent, Alaquàs, and Picanya.
The study proposes solutions such as pacifying 100% of school environments, limiting speed to 20 km/h, naturalizing spaces, creating safe school paths, and prioritizing public transport. It also highlights the importance of Low Emission Zones (LEZ) as an effective instrument to reduce traffic, especially in sensitive environments like schools. Both València and Torrent have halted their LEZ projects, which has negative repercussions on air quality.
