L'inquinamento in Cina uccide 1,6 milioni di persone all'anno, circa 4'400 al giorno. Lo rivela uno studio della Berkeley Earth, pubblicato dalla rivista Plos One che, per la prima volta, ha mappato le zone del Paese che producono più inquinanti.
Per avere un termine di paragone, le morti legate all'inquinamento sono 7 milioni all'anno a livello mondiale (dato OMS del 2012), 600'000 in Europa (dato 2010).
I ricercatori hanno monitorato 1'500 centraline in Cina e in altri paesi vicini, applicando i parametri OMS che legano le malattie ai livelli di inquinamento: circa il 40% dei cinesi vive con livelli medi di inquinanti superiori ai limiti occidentali e quasi il 17% di tutte le morti in Cina è attribuibile allo smog.
A produrre la maggior parte degli inquinanti, soprattutto polveri sottili, sono le grandi fabbriche che bruciano carbone. "Gran parte dello smog di Pechino arriva dalla provincia di Ebei, distante 400 chilometri. Per ripulire l'aria della capitale, come promesso per le Olimpiadi del 2022, serviranno interventi anche nelle regioni industriali".
