Estimating the potential health effects of cleaner air in the initial stages of the COVID-19 pandemic: a study in Malmö, Sweden.

Background: During the initial phase of the COVID-19 pandemic, reductions in air pollution were globally observed owing to decreased human activities, underscoring the potential for cleaner air through shifts in human behaviour.

Objectives: The objective of the present study was to hypothetically estimate the resulting population health impacts in Malmö, Sweden, if these improvements in air quality were to become permanent.

Methods: We utilized air pollution data from two measurement campaigns conducted in the spring of 2019 and the spring of 2020 for our Health Impact Assessment, applying standard methods.

Large-eddy simulation of aerosol concentrations in a realistic urban environment: Model validation and transport mechanism.

Air pollution in urban environments exhibits large spatial and temporal variations due to high heterogeneous air flow and emissions. To address the complexity of local air pollutant dynamics, a comprehensive large-eddy simulation using the PALM model system v6.0 was conducted.

Mandating indoor air quality for public buildings.

If some countries lead by example, standards may increasingly become normalized.

Toxicity of particles derived from combustion of Ethiopian traditional biomass fuels in human bronchial and macrophage-like cells.

The combustion of traditional fuels in low-income countries, including those in sub-Saharan Africa, leads to extensive indoor particle exposure. Yet, the related health consequences in this context are understudied. This study aimed to evaluate the in vitro toxicity of combustion-derived particles relevant for Sub-Saharan household environments.
