00:00Has the air quality in Malaysia been a bit off lately?
00:02The air was gray when I opened the window.
00:04My nose is stuffy and I keep sneezing.
00:06Even cough
00:06Why does Malaysia seem unable to escape haze every year?
00:09Today, we'll answer five major questions about haze all at once.
00:12Question 1
00:12Where does the haze come from?
00:14Let's start with the most common story, isn't it the Indonesian forest burning?
00:17The answer is
00:18Transboundary haze is indeed one of the important sources.
00:20But not all the haze comes from Indonesia.
00:22Sumatra during the dry season
00:23Forest and peatland fires in regions such as Kalimantan can produce large amounts of fire.
00:27Amount of smoke
00:27If the wind direction is favorable, the smoke may drift to Malaysia.
00:30Of course, local open burning
00:32Traffic and industrial emissions can also affect air quality.
00:34Question 2
00:35Why does the air suddenly become fresh after a rain?
00:38Because rainwater is like giving the air a bath.
00:40Some particulate matter in the air will settle down with the rain.
00:42Therefore, the air quality usually improves significantly after heavy rain.
00:45Conversely, if the weather is hot, dry, and with little rain...
00:48Pollutants tend to accumulate in the air more easily.
00:50So what is the most feared thing about haze?
00:52It was a serious downpour.
00:53Question 3
00:54Why can haze persist for several weeks?
00:56Many people think that forest fires are
00:58Once it started burning, the firefighters extinguished it, and the smoke disappeared.
01:00It's not that simple.
01:02Especially peatland fires
01:03Peat contains a large amount of plant organic matter that accumulates after drying.
01:06It can burn continuously
01:07It might even burn slowly underground.
01:09Therefore, the fire may have been extinguished by the surface smoke.
01:10But you can still keep taking risks.
01:11Question 4
01:12Why does haze appear?
01:13My nose and throat are particularly uncomfortable.
01:15Because haze contains many very fine particulate matter.
01:18For example, PM2.5
01:20They are so thin that they can enter the respiratory system.
01:22Therefore, some people may experience [symptoms] during haze.
01:24Nasal discomfort and throat irritation
01:26Coughing or dry, stinging eyes
01:28Especially for people who are particularly sensitive to air pollution
01:31It might be more noticeable
01:32So when we see the API rise
01:34It's not as simple as just enduring it.
01:36Question 5
01:37Why does Malaysia experience haze every year?
01:39Because this is not actually a problem of a single country.
01:42Forest fires, peatlands, land management, weather, wind direction, and transboundary pollution
01:46wait
01:46All of them could be involved.
01:48The haze problem in Southeast Asia has persisted for decades.
01:51The risk of haze could return if the dry season comes again.
01:54So when you see the sky is gray
01:56Remember to check the API Air Pollution Index.
01:58Reduce prolonged outdoor activities
02:00Wear a suitable mask when necessary.
02:02After all, we can't control where the wind blows.
02:04But you can control how you deal with the haze.
02:07Cannot be performed
