Residents of Zamboanga are assured of quality air based on studies by conducted by the Department of Environment and Natural Resources (DENR).

The Environmental Management Bureau of the DENR-9 recently released the results of the air quality analysis conducted for the fourth quarter of 2010.

In a letter furnished to Mayor Celso Lobregat, EMB-DENR Regional Director Alan de Gala revealed air quality in the city is still well within the 230 µg/NCum (microgram per normal cubic meter) National Ambient Air Quality Standard for Total Suspended Particulates set by the agency.

To monitor air quality, DENR has set up three air quality monitoring stations in the city to measure the concentration of air particulates in traffic-prone areas.  Twenty-four hours of continuous collection of air samples is conducted at 6-day intervals at each station.  The results are then averaged quarterly and compared against the national standard.

The three stations are distributed in various locations in the city.  One is situated inside the Zamboanga City Medical Center compound, one in Barangay Sto. Niño and another at the Philippine International Development (PHIDCO).

The latest analysis yielded an average of 134 µg/NCum (ZCMC), 120 µg/NCum (Sto. Nino) and 189 µg/NCum (PHIDCO), respectively. — Claudine Uniana/City Hall PIO
