Article Synopsis
- Airborne metal concentrations in fine particulate matter are crucial for understanding health risks and shaping air pollution strategies.
- A study analyzed ~800 PM filter samples from 19 locations (2013-2019), revealing significant metal enrichment (e.g., lead, arsenic) at certain sites, with levels much higher than natural backgrounds.
- Several cities, including Dhaka and Kanpur, surpassed health guidelines for lead and arsenic, highlighting the need for enhanced monitoring and assessment of air quality.
Exposure to ambient fine particulate matter (PM) is a leading risk factor for the global burden of disease. However, uncertainty remains about PM sources. We use a global chemical transport model (GEOS-Chem) simulation for 2014, constrained by satellite-based estimates of PM to interpret globally dispersed PM mass and composition measurements from the ground-based surface particulate matter network (SPARTAN).
View Article and Find Full Text PDFA simple high spectral resolution lidar technique using a multi-longitudinal mode laser is proposed for measuring aerosol extinction and backscattering coefficients. A scanning interferometer having the same free spectral range as the mode spacing of the laser is used to separate Rayleigh from Mie scattering. Scanning the interferometer in the span of one fringe, the lidar signals at the minimum and maximum Mie-scattering transmission are measured.
