Monitoring Stations

DENR-EMB maintains five (5) monitoring stations in

the Region. Three (3) of these stations have TSP high

volume samplers, two (2) stations have PM10

high volumesamplers and one (1) station with OPSIS Telemetry.

The method of sampling for TSP and PM10 are

measured by the high volume samplers. The sampler

consists of a vacuum system and filter housed in a shelter

and operates on the same principle as a vacuum cleaner.

The particulate matter in the atmosphere is collected by

drawing a known volume of air through a pre-weighed filter

for a 24-hour period every sixth day according to the EMB-7field monitoring schedule. The filter is then re-weighed to

determine the mass of the particles collected.

OPSIS Telemetry measures in real time in a 24-hour

period from Monday to Sunday. The results will directly be

transmitted to the computer for data management system.

i. DENR-7 Station

The DENR-7 is located in Greenplains Subdivision,

Banilad, Mandaue City with geographical coordinates of

1020'31"N 12354'51"E. The DENR-7 compound is about 50

meters from A.S. Fortuna St. and about 200 meters from

Banilad Street connecting Banilad and Talamban flyover.

The monitoring equipment installed in this station is a

Total Suspended Particulates (TSP) high volume sampler.

Previously, the equipment was set-up at the roof top of the

DENR grounds near the main gate but since there is a

building construction going on at present, it is currently

situated at the roof of the DENR-7 Motor pool (see photo A).

The station is surrounded by mixed commercial and

residential establishments. Major air pollution contributor in

this station could be attributed to the movement of

government and private vehicles passing by the entrance

gate and vying within the subdivision as well as the

vehicular emissions passing the Ban-Tal Flyover.

Nasipit, Talamban, Cebu City with geographical coordinates

of1021'5"N 12354'48"E.

USC-TC is a secluded part of the city, simulating the

conditions of a suburban setting and accessible by a single

road, which is congested even during off-peak hours of the

day . Mobile source is the major air pollution contributor

vying to and from the area (see photo E).

Climatological Data

The weather plays a significant role in air quality, it

can either help increase or decrease the amount of pollution

in the air. For the following figures below, it show the

monthly recorded temperatures from the three provinces in

the Region by the Philippine Atmospheric Geophysical and

Astronomical Services Administration (PAG-ASA) for the year

2011.
