DENR checks ambient air quality in Mt. Bulusan

Bulusan, Sorsogon—After a cycle of phreatic explosions of Mt. Bulusan in Sorsogon, resulting to heavy ash fall in adjacent areas, the Department of Environment and Natural Resources through the Environmental Management Bureau conducted a series of ambient air sampling to assess if air quality conforms with DENR standards.

EMB Regional Director Gilbert Gonzales dispatched a technical team on November 22, 2010 to evaluate the current status of air quality in affected areas of the province.

The team headed by Rommel Gapayao, officer-in-charge of the EMB Air Quality Management Section, will test ambient air quality based on the parameters of total suspended particulates (TSP) and sulfur dioxide (SO2). TSP refers to the estimated level of dust, while SO2 indicates the total amount of sulfuric compounds in the air.

Sampling stations were set up at Inlagadian, Casiguran; Añog, Juban and Gulang-gulang, Irosin.

“Laboratory result of the ambient air sampling is expected to be released the soonest possible time,” Gapayao said.

For several weeks, Mt. Bulusan showed signs of restiveness and spewed on several occasions columns of volcanic ashes that resulted to heavy ash fall. Locales fear adverse environment and health effects that the continuing eruption will wrought.
