Among the different air pollutants, particulate matter (PM) is of great concern due to its
abundant presence in the atmosphere, which results in adverse effects on the environment …

Vehicle emissions are identified as a major source of air pollution in metropolitan areas.
Emission control programs in many cities have been implemented as part of larger scale …

In this study, the temporal variations of sources of black carbon (BC) concentrations were
evaluated in the metropolitan area of Milan, Italy, during three distinct seasons over 2017 …

Abstract The Indian national capital, Delhi, routinely experiences some of the world's highest
urban particulate matter concentrations. While fine particulate matter (PM 2.5) mass …

While commuting, individuals are exposed to high concentrations of urban air pollutants that
can lead to adverse health effects. This study aims to assess commuters' exposure to …

To characterize the features of particle pollution, continuous measurements of particle
number size distributions and chemical compositions were performed at an urban site in …

Kerbside concentrations of NOx, black carbon (BC), total number of particles (diameter> 4
nm) and number size distribution (28–410 nm) were measured at a busy street canyon in …

Black carbon is a primary aerosol tracer for high-temperature combustion emissions and can
be used to characterize the time evolution of its sources. It is correlated with a decrease in …

Black carbon (BC) and particle number (PN) concentrations are usually high in cities due to
traffic emissions. European mitigation policies, including Euro emission standards, have …

In this study, we evaluated the spatial and temporal trends of black carbon (BC) in the Los
Angeles Basin between 2012–2013 and 2016–2017. BC concentrations were measured in …
