The impact of short-term exposure to criteria air pollutants on sleep disturbance among young adults: A nationwide analysis in 261 Chinese cities.

Backgrounds: Evidence concerning the short-term acute effect of air pollution on sleep health is quite limited. This study aims to examine the association between short-term exposure to ambient criteria air pollutants (CAPs) and sleep disturbance among young adults.

Methods: A nationwide retrospective study was conducted across 261 Chinese cities from 2023 to 2024.

A novel approach for large-scale characterization of residential cooking-generated PM with computer vision and low-cost sensors.

Cooking is one of the major sources of indoor particulate matter (PM), which poses significant health risks and is a severe health hazard. Current studies lack an economical and effective analytical framework for quantifying inhalable particles (PM) and fine particulate matter (PM) from residential cooking activities on a large scale under real-world scenarios. This study bridges this gap by employing computer vision (CV) technology and readily available sensors.
