Weather warning as air pollution in Karachi increases dangerously
KARACHI: The city witnessed “very unhealthy” air pollution levels on Saturday, which the weather service said could continue for another day or two, prompting health experts to warn that such weather conditions could lead to several infections and that people should avoid exposing themselves to. to such an atmosphere to avoid “lasting effects”.
The U.S. Consulate Karachi’s Air Quality Monitoring Stream posted several tweets on its social media platform and in the latest tweet the air quality was rated at 204 U.S. AQIs. . [air quality index] at 6 p.m. in town.
Amateur meteorologists and officials said it was the second worst air quality on record in the entire country after Bahawalpur, where the air quality was recorded at 180 US AQI. Weather experts and officials called it the impact of the change in wind direction and seemed confident that although it was unhealthy, it was not a new or abnormal phenomenon.
“This often happens whenever the wind changes direction,” Sardar Sarfaraz told the Met office while explaining the reasons for the cool weather experience for the Karachiites.
Health expert urges citizens to avoid exposure to dusty air
“You can call it foggy or dusty weather and there is a very obvious reason for such a trend. There is strong wind pressure from the Afghanistan and Central Asian side which has led to the northwesterly wind direction. Since this particular side has a desert area of the Chaghi of Balochistan, we see that there are dust particles that make it hazy and unhealthy.
Not the smog seen in Lahore
Responding to a question on any comparison between the current weather conditions of Karachi and Lahore, which have often witnessed unhealthy levels of air pollution mainly during the winter season, Mr Sarfaraz ruled out any parallels between the weather conditions of Karachi and Lahore. two cities calling the current trend in the port city “temporary”.
“In Lahore, it is in fact the smog which affects the air quality index and the situation often worsens”, he added.
“This smog basically comes in the form of a combination of smoke and fog which ultimately creates that atmosphere that lasts for several days and that we often see in winter in Lahore. But here it is nothing new every time that “There is a change in wind direction, the city is witnessing weather conditions such as dust or fog. This is a temporary thing and we hope it will be over within a day or two.”
Lahore in winter often witnesses the worst air quality that normally remains from October to February in the capital of the Punjab, when farmers are accused of setting the remains of their crops on fire, producing smoke that adds to smog.
The situation worsened in November 2019 when Lahore was ranked second after Delhi as the most polluted city in the world on several major and globally recognized air quality ranking sites.
While the Met Office’s forecast of current weather conditions may bring a sigh of relief to the Karachi people, health experts have warned that even a temporary phenomenon of “very unhealthy” air quality could have a lasting effect.
“So the best thing to do is to avoid exposure to such air,” said Dr Qaiser Sajjad of the Pakistan Medical Association (PMA). “We have already started to see an increase in the number of patients with colds and flu. For those who have to go out for different reasons, mainly bikers, should protect themselves and keep their face covered. These weather conditions can lead to nasopharyngitis, throat infection, bronchitis, and lung infection. Those who suffer from nasal allergy should also take care of themselves in these weather conditions. “
