Retention of particulate organic matter in a tropical headstream
(Springer, 2002-08-01)
Retention of particulate organic matter was investigated over a range of water discharges in pool and riffle zones of a tropical stream (Itauna Stream, São Paulo, Brazil). A closed-system leaf release and capture method ...
Downward fluxes of particulate organic matter in coastal and oceanic areas off Chile: The role of the OMZ and functional groups of the plankton
(Universidad de Concepción.Facultad de Ciencias Naturales y Oceanográficas., 2006)
Forest Fires in the Brazilian Amazon and their Effects on Particulate Matter Concentration, Size Distribution, and Chemical Composition
(2022-01-01)
The number of fires in the Brazilian Amazon rainforest has increased in recent years. Particulate matter emitted from these fires can affect different locations, depending on air mass trajectories. Characterization of such ...
Ocular Exposure to Particulate Matter and Development of Pterygium: A Case-Control Study
(NIOC 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 ...
Co-accumulation of microbial residues and particulate organic matter in the surface layer of a no-till Oxisol under different crops
(Pergamon-Elsevier B.V. Ltd, 2012-07-01)
In the absence of significant mechanical disturbance such as under permanent no-till (NT), crop type should be a prominent factor controlling soil organic C (SOC) pools. Microbial cell residues have been shown to be ...

Vehicular particulate matter emissions in road tunnels in Sao Paulo, Brazil
(Springer, 2009-02)
In the metropolitan area of São 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 ...
Electrochemical characterization of mangrove sediments: A proposal of new proxies for organic matter oxidation
(Elsevier, 2019)
The voltammetric response of microparticulate deposits resulting from solvent evaporation of ethanolic extracts of mangrove sediments in contact with aqueous acetate buffer is hereby described. Dated sediment cores sampled ...
Vehicular particulate matter emissions in road tunnels in Sao Paulo, Brazil
(SPRINGER, 2009)
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 ...
Toxicogenetic monitoring in urban cities exposed to different airborne contaminants
(2013-04-01)
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 ...
