Abstract

Miliardi di persone sono esposte a livelli di inquinamento cittadino eccedenti gli standard normativi per la protezione della salute. Il verde urbano può certamente aiutare ad abbassare le concentrazioni dei principali inquinanti atmosferici quali particolato (PM), biossido d’azoto (NO2) ed ozono (O3) anche se la scelta delle specie arborea risulta basilare. Il modello FlorTree ha permesso di classificare 221 specie considerando l’assorbimento stomatico di NO2 ed O3, la deposizione del PM e l’O3-formazione dovuta all’emissione di composti organici volatili. Una web APP è stata sviluppata per individuare le specie migliori per la qualità dell’aria cittadina. In base a questi risultati, è stato piantato all’interno del Comune di Firenze un piccolo bosco urbano con tigli, olmi, aceri e cipressi per quantificare, tramite apposita sensoristica, la rimozione effettiva degli inquinanti da parte della vegetazione. Il monitoraggio biennale ha evidenziato una riduzione sotto chioma per NO2, O3 e PM. Inoltre, si è verificato il rispetto della regola 3-30-300 (3 alberi visibili dalla propria abitazione, 30% di copertura arborea nelle vicinanze, 300 metri di distanza da spazi verdi) a Firenze.  I risultati hanno mostrato come il 37% degli edifici non rispetti nessun criterio, dimostrando chiaramente come il rinverdimento urbano sia necessario per migliorare la qualità dell’aria e la salute delle persone. A Firenze la copertura arborea è circa il 17% (se consideriamo gli alberi più alti di 3 m) o 30% (se consideriamo anche arbusti e prati), ed è in grado di rimuovere dall’atmosfera inquinanti pericolosi. Se Firenze raggiungesse il 30% di copertura arborea, si potrebbero prevenire 57 morti premature per inquinamento atmosferico all’anno rispetto al 2019.
