Incendios, humo y alerta por "lluvia negra": ¿Cómo afecta a la salud?
Los incendios en Bolivia, la Amazonia y Argentina continúan afectando la calidad del aire. En Buenos Aires, el humo se ha disipado temporalmente debido a un cambio de viento, pero persiste en las provincias del norte, complicando la situación para personas con problemas respiratorios. El Dr. Sergio Zunino, neumonólogo, recomienda mantener las ventanas cerradas y usar barbijos N95 para minimizar la inhalación de partículas dañinas.

00:00...fires in Bolivia, there are still fires in the Amazon, also some in Argentina.
00:04And now, for a little while, the smoke has gone, because the wind changed, the fog came,
00:08but the smoke is there, waiting, waiting, at any time it comes back.
00:11For now, I say, it comes back to Buenos Aires, for now it is in the provinces of the north,
00:16there the matter is also very complicated, because the smoke affects people who have allergy problems.
00:23The smoke that comes from these fires, what it generates is a moment of high environmental pollution,
00:31and I have on a screen Sergio Zunino, a clinical doctor, he is a pneumonologist.
00:35Dr. Zunino, good morning.
00:38What does it generate and how should we take care of the smoke when these moments of pollution come?
00:44Well, good morning, Rolando.
00:46The issue of smoke involves the vehicleization of particles that are inspired,
00:53and are harmful to everything that is the respiratory tree.
00:58Not only that, but also that they attack the eyes, the face, the nose...
01:04Only allergic people or anyone?
01:06They are in the nose, in the eyes and in the throat, right?
01:10Only allergic people or does anyone get this?
01:13No, no, this depends on the sensitivity of each person.
01:16Logically, those who have allergies, which is an exaggerated reaction to certain triggers,
01:23such as substances that are in the environment, not only to smoke, to pollen and others,
01:29make a slightly more important reaction, and logically these people are more susceptible
01:34to the effects of these particles that the smoke vehicles.
01:38Is it advisable to wear a beard, to return to the old beard?
01:42Let's see, let's imagine that these particles have microns, that is, they are very small.
01:47The beard in general, only those that are the thickest, like the N95,
01:52can filter the thickest, but it is not that they will protect us 100%
01:58of being able to inspire these particles.
02:01Taking advantage of the cold, is it convenient to avoid opening the window?
02:05No, no, no, no.
02:07If there is smoke in the environment, it is just the opposite.
02:11It is important to keep the windows closed and keep clean air inside the homes.
02:15That is, keep it closed, that is, do not open the window.
02:18No, no, no, no, no.
02:20In the days that we have the atmosphere saturated with smoke,
02:24those days we have to have the windows closed and try to,
02:27if we go out, we are going to put on a beard and try to avoid,
02:30in those people with chronic diseases, outdoor activities, right?
02:34Ah, that's important, avoid going out for a run and these things,
02:38you end up inhaling the air with the jeans, right?
02:42Because in practice, this is the old jean.
02:44Of course, if I have, let's say, asthma or chronic obstructive pulmonary disease
02:48or heart disease, and the whole atmosphere is not seen by the sun
02:52because everything is, let's say, opaque because of the smoke,
02:56all I do is inspire more with a faster breathing rhythm
03:01when I'm running, I'm going to expose myself much more to these particles.
03:05And logically, I'm going to be predisposed to trigger an asthma attack,
03:09a POG rehabilitation, an associated respiratory infection,
03:13and even all this can generate genetic damage
03:16and can trigger cancer in the long run.
03:19Yes, it must be said that in cities like Buenos Aires,
03:22in general, the cities of the plain, where the winds circulate much more,
03:26we are not used to measuring the environmental pollution index,
03:29but in cities like Chile, like Mexico, like Beijing,
03:34they give you the temperature, the thermal sensation,
03:37and the environmental pollution index.
03:40In this case, it is a situation of high environmental pollution.
03:43Yes, in reality, we, many do not know, but we have in Buenos Aires
03:47five environmental pollution meters distributed in different places.
03:52For example, there is one near the Naval Hospital.
03:55What happens is that they are not updated in terms of their measurements in this program.
03:59Ah, they are not updated.
04:01You have to change the software.
04:05It may be. In reality, yes, we know that all this is harmful to health,
04:10and from the Argentine Association for Respiratory Medicine,
04:13we want to prevent those people who have environmental pollution.
04:16But the applications measure environmental pollution. They give it to you, right?
04:20Yes, yes, exactly. There are some that do.
04:25Doctor, we thank you very much for your contact.
04:27No, well, thank you very much and have a good day.
04:30I have to say, Mimí, that this has eased a little,
04:32because yesterday it was smoke and there was much more concern.
04:36What happened? Did the wind take it away?
04:38Now there is fog, it remained only in the provinces of the north.
04:41Explain to me what happened.
04:42No, Rolo, it is simply a relief, but for the province of Buenos Aires,
04:46because the remaining provinces of the north central area of the country
04:49are still maintained with this smoke effect.
04:53Why? Because the north wind continues to blow,
04:56that smoke that occurs in the province,
04:59that occurs in Brazil, also in Bolivia and Paraguay,
05:03and continues to advance over the northern area of our territory.
05:07The province of Buenos Aires, for now, is already far from this phenomenon.
05:11Why? Because we are having fog and we are also going to have rains today,
05:16particularly in the central area of the province of Buenos Aires,
05:20here in the federal capital and also in the area of La Plata.
05:23Today we have had a relief, a relief that is going to last
05:27at least until tomorrow, Wednesday.
05:29This does not mean that the smoke can return
05:32in the course of the week.
05:34And in the meantime, I am showing you
05:36what is going to happen over time.
05:38I anticipated rains for today.
05:41For now, quite intense fogs in the federal capital,
05:44in the Bonaerense suburb,
05:46which drastically reduce rain visibility.
05:49And in the hours of day and night,
05:52rains and storms that will last until tomorrow,
05:55in the early hours of the morning.
05:57Then the weather will improve.
05:59If the smoke returned, the rain would clean it.
06:01Exactly.
06:03While it is raining,
06:05those possibilities of smoke in suspension exist.
06:08But then, when the conditions improve,
06:11we can have that effect again.
06:14Especially Thursday, Friday and Saturday,
06:17days when it will be sunny,
06:19no rains are forecast,
06:21with temperatures that will increase,
06:23but with a forecast of winds
06:25that may be rotating the northern sector
06:27and the phenomenon may return.
