PM2.5 IN BANGKOK

Bangkok Post - - FRONT PAGE -

Weather

PM 2.5 has been a prob­lem for over a decade and in­ten­si­fies dur­ing the cool sea­son. Cur­rently, high pres­sure from China cov­er­ing Bangkok from De­cem­ber to early Fe­bru­ary pre­vents PM2.5 from ris­ing up and be­ing dis­persed at a higher al­ti­tude.

Ve­hi­cles

The ma­jor source of PM2.5 in Bangkok is from trans­porta­tion and burn­ing, ac­cord­ing to the Pol­lu­tion Con­trol De­part­ment.

Con­struc­tion

Dust par­ti­cles from con­struc­tion sites are big­ger than PM2.5 but still cause pol­lu­tion. Ma­jor in­fra­struc­ture projects in­clud­ing the Sky­train and sub­way sys­tems are paralysing traf­fic across the city, which does worsen PM2.5 lev­els.
