Particulate matter emission factors for biomass combustion
Emission factor is a relative measure and can be used to estimate emissions from multiple sources of air pollution. For this reason, data from literature on particulate matter emission factors from different types of biomass ...
Effects of the fractal structure and size distribution of flocs on the removal of particulate matter
This study sought to evaluate the effect of form and particle size distribution of formed flocs during flocculation on the removal of particulate matter (PM) by settling. The understanding of the intrinsic processes of ...
An overview of particulate matter measurement instruments
This review article presents an overview of instruments available on the market for measurement of particulate matter. The main instruments and methods of measuring concentration (gravimetric, optical, and microbalance) ...
Evaluation and mathematical modeling of the removal of particulate matter in a real-scale lawn channel
(Assoc Brasileira Recursos Hidricos-abrh, 2016-01-01)
A mathematical model was applied to describe the removal of particulate matter in a real-scale lawn-lined channel. For this purpose different initial concentrations (Co) of particulate matter were investigated, as follows: ...
Vehicular particulate matter emissions in road tunnels in Sao Paulo, Brazil
In the metropolitan area of Sao Paulo, Brazil, ozone and particulate matter ( PM) are the air pollutants that pose the greatest threat to air quality, since the PM and the ozone precursors ( nitrogen oxides and volatile ...
Environmental studies in two communes of Santiago de Chile by the analysis of magnetic properties of particulate matter deposited on leaves of roadside trees
(Elsevier Ltd, 2017)
© 2016 The Authors Emissions from motor vehicles are considered to be one of the main sources of airborne particulate matter in Santiago. International researchers have shown that particulate matter contains metal oxides ...
Ocular Exposure to Particulate Matter and Development of Pterygium: A Case-Control Study
(National Iranian Oil Company Health Organization, 2018)
BACKGROUND: Formation of pterygium has been mainly attributed to exposure to the ultraviolet (UV) radiation. Other factors such as dry weather, wind exposure and microtrauma with dust particles, have been linked to development ...
Toxicogenetic monitoring in urban cities exposed to different airborne contaminants
Microparticles found in the air may be associated with organic matter that contains several compounds, such as Polycyclic Aromatic Hydrocarbons (PAHs) and nitro-PAHs, and may pose a significant risk to human health, possibly ...
Seasonal distribution and modeling of diesel particulate matter in the Southeast US
