The air we breathe is full of invisible dangers. Gases like carbon monoxide, nitrogen dioxide, ozone, and sulfur dioxide are not just unpleasant; they can seriously harm people with lung diseases. These diseases include fibrotic interstitial lung diseases, with idiopathic pulmonary fibrosis being a prime example. The tricky part is figuring out how much these gases affect lung health. Different methods of measuring exposure can give different results.

Three methods were put to the test: nearest neighbor, inverse distance weighting, and Kriging. Each method has its own way of estimating how much of these gases people are breathing in. The goal was to see which method gives the most accurate picture of lung health risks. Kriging came out on top. It had the lowest prediction error for all four gases. This means it was the best at guessing the actual levels of these pollutants in the air.

Kriging also showed the highest accuracy over large areas and long periods. This is important because pollution levels can change a lot from place to place and from day to day. The study looked at a big group of people with lung diseases. It found that higher levels of carbon monoxide, sulfur dioxide, and nitrogen dioxide were linked to worse lung function. The Kriging method gave the most precise measurements for sulfur dioxide and carbon monoxide.

This study shows that Kriging is a reliable way to measure air pollution. It gives a clear picture of how these gases affect lung health. This information is crucial for future studies. It helps scientists understand the true impact of air pollution on people with lung diseases. It's a reminder that the air we breathe can have serious consequences. It's not just about feeling uncomfortable; it's about our health. So, next time you hear about air pollution, think about how it might be affecting your lungs.
