Pekanbaru, Riau (ANTARA) - Forest fire-induced smog, enveloping Pekanbaru, Riau Province, has lowered visibility and polluted the air, according to the Pekanbaru meteorology station.

Haze from forest fires blanketed Pekanbaru in the morning, although on Friday afternoon, the air quality had improved, and the air was relatively clear, he pointed out.
The concentration of coarse particulate matter (PM10) in the air had risen and considered unhealthy, as it had exceeded 150 micrograms per cubic meters, he remarked. The city's air quality has continued to deteriorate since Saturday at 2 a.m. local time.
"At 8 this morning, the PM10 is at 160," he stated.
The visibility rate dropped to two kilometers in Pekanbaru and Dumai, three kilometers in Pelalawan, and six kilometers in Rengat.
The haze, shrouding Pekanbaru, came from forest fires in the neighboring districts of Siak and Pelalawan.
