Why does pollution increase in cold weather?

 With the onset of winter each year, air pollution begins to increase. The amount of air pollution has started increasing this year as the weather is getting colder. On Wednesday, air pollution in five places outside the Kathmandu Valley exceeded the danger mark.

According to the Air Pollution Measurement Center, the PM10 indicator measuring 112.99 micrograms / cubic meter was measured on Wednesday. The PM2.5 was measured at 106.09 micrograms / cubic meters, measuring the number of harmful gases such as carbon monoxide, sulfur, and nitrogen oxides in the air.

According to the Center, the level of air pollution in Bharatpur and Janakpur has not exceeded the danger level.

Why does pollution increase in winter?

The air is cold in winter too. The density of cold air is so high that it cannot fly away as easily as hot air. The upper bouts featured two cutaways, for easier access to the higher frets. Thus the layer of cold and hot air creates pollution within this atmosphere. Due to which pollution is more in the winter season.

Thus, when there is more pollution in cold weather, lung cancer also increases in non-smokers. Niraj explains the bomb. Pollution not only causes allergies in people but also causes heart attacks and diabetes. The bomb says.

How much does pollution affect health?

More than 20 percent of deaths from heart disease are caused by air pollution. According to doctors, pollution contributes to 43 percent of all lung deaths.

Various studies have shown that the effects of pollution are even more alarming. According to the State of Global Air Report-2020, pollution is also the cause of 42,100 deaths in Nepal every year.

Studies have shown that most people die of COPD (lung-related disease) due to pollution. Sixty-six percent of deaths from lung problems have been attributed to pollution.

Experts also say that 24 percent of deaths from heart disease are due to air pollution. According to experts, the biggest impact of air pollution is on the lungs. Contaminated airborne particles initially reach the lungs through respiration. So it seems to have more effect. In the end, it also affects the limbs. But if we look at death, most of the deaths are due to pollution.

How does pollution affect health?

When it comes to air pollution, invisible PM 10 and PM 2.5 are mentioned. Of these, PM10 is associated with dust particles in the air, and PM2.5 is associated with harmful gases such as carbon monoxide, sulfur, and nitrogen oxides.

Tribhuvan University Teaching Hospital, Maharajgunj Senior Chest Specialist Dr. According to the bomb, these gases in the polluted air enter the lungs through the trachea and reach the blood through the trachea and ducts.

Oxygen from the trachea and ducts coming out of the air reaches the blood and the process of expelling the harmful substance carbon dioxide from the ducts to the trachea of ​​the lungs continues in the circulatory system.

PM2.5 gas particles are bad for health. It also contains carcinogens such as nicotine, catechism, nitrogen dioxide, ozone, and sulfur dioxide.

These gases enter through the trachea. These harmful substances reach the bloodstream through various organs and harden the blood vessels. Which raises our blood pressure.

Electric stove to reduce kitchen costs

Rising prices of petroleum products and gas have made Nepali kitchens more expensive. A few days ago, the Nepal Oil Corporation suddenly increased the price of gas by Rs 75 per cylinder. Which has made the Nepali kitchen even more expensive.

On the one hand, the price of imported gas is increasing and on the other hand, the electricity produced in Nepal is looking for a market. For this, the Electricity Authority has also reduced the basic electricity tariff from Wednesday. But now what to do to avoid the impact of rising gas prices? Experts suggest that the kitchen be electrified to control rising prices.

Prakash Sharma Dhakal, who works in the Ministry of Energy, Water Resources and Irrigation, emphasizes the need to promote the concept of an electric kitchen to control the use of gas. He says that it is necessary to encourage the use of electric stoves to increase the internal consumption of electricity.

According to a government study, displacing cooking gas and using an electric stove alone can reduce total carbon emissions by 11 percent. Therefore, experts believe that electric stoves will help control inflation and reduce carbon emissions.
