Heavy-duty vehicles (HDVs) disproportionately contribute to the creation of air pollutants
and emission of greenhouse gases—with marginalized populations unequally burdened by …

Air pollution, characterized by high levels of particulate matter (PM), poses the greatest
environmental threat to human health, causing an estimated 7 million deaths annually and …

Disparity in air pollution exposure arises from variation at multiple spatial scales: along
urban-to-rural gradients, between individual cities within a metropolitan region, within …

There is growing evidence that ultrafine particles (UFP; particles smaller than 100 nm) are
likely more toxic than larger particles. However, the health effects of UFP remain uncertain …

Chromatin is now regarded as a heterogeneous and dynamic structure occupying a non-
random position within the cell nucleus, where it plays a key role in regulating various …

Ambient particulate matter (PM) pollution is a major environmental health risk in urban
areas. Dense networks of low-cost air quality sensors are emerging to characterize the …

Mobile sampling studies have revealed enhanced levels of secondary organic aerosol
(SOA) in source-rich urban environments. While these enhancements can be from rapidly …

Low-cost air pollution monitors are increasingly being deployed to enrich knowledge about
ambient air-pollution at high spatial and temporal resolutions. However, unlike regulatory …

Diverse urban air pollution sources contribute to spatially variable atmospheric
concentrations, with important public health implications. Mobile monitoring shows promise …

To investigate the chemical compositions, sources, and aging processes of submicron
particles (PM1), a comprehensive field campaign was conducted in Guangzhou urban area …
