Determination of mass concentrations of airborne PET microplastics using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS)
Ubiquitous airborne microplasctics are present in the inhalable fraction of ambient particulate matter. They may induce lesions in the respiratory system dependent on individual susceptibility and particle properties.
Paper
Real-time chemical characterization of primary and aged biomass burning aerosols derived from sub-Saharan African biomass fuels in smoldering fires
The influence of biomass burning (BB)-derived organic aerosol (OA) emissions on solar radiation via absorption and scattering is related to their physicochemical properties and can change upon atmospheric aging.
Paper
Oxidative potential of atmospheric particulate matter collected in low-income urban settlements in South Africa
Higher redox activity was determined for the finest particles for both outdoor and indoor aerosols. DTT redox activity of particulates had strong correlations with organic and inorganic species for outdoor and indoor samples.
Paper
Exploring the influence of physical and chemical factors on new particle formation in a polluted megacity
In polluted environments, the condensation sink, along with relative humidity and aerosol liquid water content, plays a key role in suppressing new particle formation events, which appear largely unaffected by aerosol chemical composition.
Paper
Air pollution (PM2.5) and its meteorology predictors in Kampala and Jinja cities, in Uganda
This study contributes insights into the air quality challenges faced by two rapidly urbanising cities in Uganda and lays the groundwork for informed decision-making to protect public health and promote a sustainable environment.
Paper
Characterization of particulate matter in a multizonal residential apartment: transport, exposure, and mitigation
Spatio-temporal monitoring in a multizonal apartment focussing on inter-zonal transport, multizonal exposure, and characterization of mitigation techniques (portable air cleaner, air conditioners, natural ventilation, and filter sheets).
Paper
Fine particulate air pollution estimation in Ouagadougou using satellite aerosol optical depth and meteorological parameters
Framework for analysis of PM2.5 estimates.
Paper
Variability in air quality, ozone formation potential by VOCs, and associated air pollution attributable health risks for Delhi's inhabitants
The present long-term study has been conducted with dual objectives: firstly, to monitor the spatio-temporal variation of ambient air quality parameters and secondly, to evaluate the impact of air pollutants on the Delhi population.
Paper
Characterization of mercury in atmospheric particulate matter in the state of Rio de Janeiro, Brazil
The study investigates mercury levels in PM2.5 in regions of Rio de Janeiro: urban areas, areas affected by sugar cane burning, and an environmental reserve. It highlights seasonal variations and pollution contributions, both local and transboundary.
About this collection
Understanding the sources and composition of air pollutants in emerging economic regions is essential for implementing effective pollution control measures and mitigating the adverse impacts on human health and the environment. Addressing air quality issues in these regions is important for sustainable development, as poor air quality can impede economic growth and hinder progress towards achieving global environmental goals. This collection highlights the impactful atmospheric science research occurring in these regions.
