Concentrations and Size Distributions of Particle Lung-deposited Surface Area (LDSA) in an Underground Mine

Aerosol and Air Quality Research, 2021
Ultrafine particles produced by diesel-powered vehicles in underground mines are largely unaccounted for in mass-based air quality metrics. The Lung Deposited Surface Area concentration (LDSA) is an alternative to describe the harmfulness of particles ...

Aerosolized Antibiotics [PDF]

Respiratory Care, 2015
Administration of medications via aerosolization is potentially an ideal strategy to treat airway diseases. This delivery method ensures high concentrations of the medication in the targeted tissues, the airways, with generally lower systemic absorption and systemic adverse effects.

A novel in-situ method to determine the respiratory tract deposition of carbonaceous particles reveals dangers of public commuting in highly polluted megacity

Particle and Fibre Toxicology, 2022
Background Exposure to air pollutants is one of the major environmental health risks faced by populations globally. Information about inhaled particle deposition dose is crucial in establishing the dose–response function for assessing health-related ...

An online monitor of the oxidative capacity of aerosols (o-MOCA) [PDF]

Atmospheric Measurement Techniques, 2017
The capacity of airborne particulate matter to generate reactive oxygen species (ROS) has been correlated with the generation of oxidative stress both in vitro and in vivo.

Active aerosols

Optics Express, 2022
We report the dynamics and control of the orientational and positional order of ensembles of gold nanorods suspended in air at standard temperature and pressure using externally applied electric fields, demonstrating an active aerosol. Light filter, valve and gradient responses are shown, establishing active aerosols as a unique type of optical element

Aerosol emissions and gravity waves of Taal volcano

Scientific Reports, 2022
The Taal volcano (14.0 N, 121.0 E) in Philippines erupted in January–February 2020, with a part of aerosols drifted northward and detected by a lidar system at Kaohsiung city (22.37 N, 120.15 E), Taiwan.

Characterization of aerosol properties at Cyprus, focusing on cloud condensation nuclei and ice-nucleating particles [PDF]

Atmospheric Chemistry and Physics, 2019
As part of the A-LIFE (Absorbing aerosol layers in a changing climate: aging, LIFEtime and dynamics) campaign, ground-based measurements were carried out in Paphos, Cyprus, to characterize the abundance, properties, and sources of aerosol particles in ...

Evaluation of Multiangle Absorption Photometry for Measuring Aerosol Light Absorption [PDF]

, 2005
A new multiangle absorption photometer for the measurement of aerosol light absorption was recently introduced that builds on the simultaneous measurement of radiation transmitted through and scattered back from a particle-loaded fiber filter at multiple
