A study focused on creating a dust emission inventory in a new city in China to help control air pollution. They checked how much dust came from soil, roads, and construction sites using high-tech methods. The findings showed that most of the dust came from roads and construction, with roads making three times more dust. Big construction projects caused a lot of the dusty air pollution. Dust from roads was a big issue, and how much dust ends up in the air can change a lot throughout the year. When it's dry, there's more dust. The study suggests that controlling dust from different sources is important, especially during bad weather, to tackle air pollution.
