Pekanbaru – Haze returned on Thursday to the skies of Pekanbaru, raising concern over new breathing problems spreading in the city.

Pekanbaru Deputy Mayor Erwandy Saleh said that the quality of the air in the city was poor.

Pekanbaru Meteorological and Geophysics Agency recorded on Thursday the haze density at 120 particulate matters per 10 micron, considerably higher than the minimum threshold of 100 particulate matters per 10 micron. Erwandy blamed the forest fires for the return of haze to the city.
