00:00Unhealthy air quality has been recorded in some places in Metro Manila, the BNR.
00:06There is even evidence of the formation of a volcanic smog of Volcang Taal here.
00:12This is what Rod Lagusan reported.
00:15A large part of Batangas was covered by a volcanic smog of Volcang Taal.
00:21According to PhiVox, it is a mixture of water vapor and particulates with sulfur dioxide.
00:26Because of this, many schools suspended classes in the province
00:30which was later followed by a suspension of DepEd classes throughout Calabarzon and NCR.
00:35But how did this happen?
00:37Because there are occasions when a lot of sulfur dioxide flows into Volcang Taal,
00:41but this does not cause a smog.
00:43According to PhiVox Director Teresito Bacolcol, the air is slow.
00:56The air is slow, that's why there was a smog.
00:58It's just a small amount.
01:00Basically, we reached 18,000 on March 28.
01:03On January 25, we reached 15,000.
01:06So, generally, it's low.
01:08But again, because the air is so low, it cannot rise.
01:13It's not moving one meter per second.
01:16It's too slow.
01:18Aside from the Taal area, the wind speed in Metro Manila is low.
01:22How long will this last?
01:24According to the agency, there are a lot of things that are affected,
01:26such as rain or strong winds.
01:28Sulfur dioxide is acidic,
01:30and it can irritate the eyes,
01:32the lungs,
01:34and the respiratory tract.
01:36So, the severity,
01:38the effect of this on us,
01:40depends on the volume,
01:42the gas concentration,
01:44and the duration of exposure.
01:46Those with health conditions are particularly sensitive to smog,
01:49such as cough, lung and heart disease,
01:51elderly, pregnant women, and children.
01:53Meanwhile, when it comes to the situation in Metro Manila,
01:55in Pagasa,
01:57based on their analysis,
01:59it's possible that a volcano came here.
02:01When the wind came last night,
02:03it lasted because
02:05the wind was calm.
02:07And then,
02:09the high-pressure area
02:11was exposed,
02:13where the air is subsidence,
02:15which means the air is low.
02:17So, the part,
02:19the fog,
02:21in the sky,
02:23because it's blocked by
02:25the high-pressure area.
02:27It needs a lot of rain
02:29to remove the fog in a large area.
02:31According to the Environmental Management Bureau of DNR,
02:33Makati City has a very unhealthy air quality index
02:35with 2.5 particulate matter.
02:37While in the monitoring stations
02:39in Caloocan City,
02:41Pateros, and Paranaque City,
02:43the air quality index
02:45is unhealthy for sensitive groups
02:47with 2.5 particulate matter.
02:49According to DNR-EMB,
02:51the current level of air pollution
02:53may be due to the emission of cars,
02:55especially if it's a rush hour,
02:57and the effect of the so-called thermal inversion
02:59where the air pollutants are trapped.
03:01While the haziness and fog
03:03may be due to the fog.
