Kathmandu, February 16: Kathmandu, the capital of Nepal, has become the most polluted city in the world. According to IQ Air, a Swiss company that measures air quality, the Kathmandu Valley became the most polluted city in the world on Saturday evening.

Here, the air quality is measured as Kathmandu Valley (Kathmandu, Lalitpur, and Bhaktapur). On Saturday, the air quality index (AQI) of Kathmandu reached 175, which is an unhealthy situation. The AQI of Jawalakhel in Lalitpur has reached 213, which is very unhealthy.

Kinshasa, the capital of the Democratic Republic of Congo, is the second most polluted city in the world after Kathmandu. It is followed by China’s Wuhan, China’s Shanghai, Uzbekistan’s Tashkent, Myanmar’s Yangon, Vietnam’s Hanoi, India’s Delhi, Bangladesh’s Dhaka and China’s Guangzhou in the top 10.

When the monsoon winds, which bring rain to the Kathmandu Valley, return to the Bay of Bengal, a layer of pollution is formed in the atmosphere due to polluting vehicles, wind-blown dust and western cold dry air.

From the first week after the departure of the monsoon, the rainfall also decreases as the westerly wind becomes active and cools down. The nature of cold air is always flowing clinging to the ground.

After cooling it becomes dense and it also collects the small particles of fog present in the atmosphere and brings them to the lower level. Particles of haze from the Earth’s surface also accumulate in the same deep cold western air at the lower levels of the atmosphere.

During the hot and dry summer season, which lasts from Fagun to Jeth, air quality in Nepal’s federal capital Kathmandu has repeatedly reached the world’s most polluted level in the past year. The air quality of Nepal’s cities has been unhealthy since the first week of the winter season.

When the west wind is active, there is some rain in the first seven days of the month. At other times, even if it rains sporadically, it does not fall as often as the level of pollution in the atmosphere.

Although the temperature starts increasing from Magh, due to less rainfall, the layer of smoke and dust does not disappear immediately from the sky of the valley, low-altitude river banks and lowland areas.

According to experts, air pollution affects the respiratory system the most. On being unwell because of this pollution cold attacks different parts of the body together. The pollution-ridden winters cause problems ranging from swelling of the hands to the eyes. Living in an air-polluted area increases the risk of a heart attack.

That’s why doctors have recommended the mandatory use of masks to prevent toxic haze particles from entering the lungs in the polluted cold air of winter.
