Cooking with wood may cause lung damage | Instant News

They used two tools to measure the impact. One is a traditional test, such as spirometry, which measures the airflow in the lungs. Researchers conducted this test after measuring the concentration of pollutants in the house. Another test is an advanced CT scan, which allows quantitative measurements. In one case, researchers scanned a person when they breathed in, and then scanned after they breathed out. Then, they learned how the lungs work by measuring the differences between the images.

Compared with people who use LPG, people who cook with wood biomass are exposed to higher concentrations of pollutants and bacterial endotoxins. They also suffer from diseases related to lung disease, which is a significant increase in the level of air retention in the lungs.

Kizhakke Puliyakote said: “Air capture occurs when a part of the lungs cannot effectively exchange air with the environment. Therefore, the next time you breathe, you will not absorb enough oxygen in that area and eliminate carbon dioxide.” “That part of the lungs Damaged exchange.”

The use of CT scans allows researchers to discover information about how smoke affects the lungs, showing a larger range than traditional tests show.

Kizhakke Puliyakote said: “Traditional tests do not reflect the degree of damage caused by the raw material fuel.” “You need more advanced and sensitive technology, such as CT imaging. The main advantage of using imaging is that it is very sensitive, you can Before the disease develops into a complete outbreak, subtle regional changes are detected, and the progress of the disease can be tracked in a short period of time.”

In addition, compared with other smoker studies, some biomass users have higher sensitivity, Kizhakke Puliyakote said.

This is not the first study to examine the risks of wood fires.

In 2014, researchers from Liverpool School of Tropical Medicine and Ohio State University Find About 600 to 800 million families worldwide are at increased risk of diseases, including pneumonia, asthma and lung cancer caused by household air pollution caused by burning wood indoors for cooking.
