Influence of Intensive Agriculture on Dry Deposition of Aerosol Nutrients
(Soc Brasileira Quimica, 2014)
Source apportionment of PM10 and PM2.5 at Tocopilla, Chile (22A degrees 05' S, 70A degrees 12' W)
(SPRINGER, 2009)
Tocopilla is located on the coast of Northern Chile, within an arid region that extends from 30A degrees S to the border with PerA(o). The major industrial activities are related to the copper mining industry. A measurement ...
Source apportionment of ambient PM2.5 in Santiago, Chile: 1999 and 2004 results
(ELSEVIER SCIENCE BV, 2012)
A receptor model analysis has been applied to ambient PM2.5 measurements taken at Santiago, Chile (33.5 degrees S, 70.7 degrees W) in 2004 (117 samples) and in 1999 (95 samples) on a receptor site on the eastern side of ...
Structural signatures of water-soluble organic aerosols in contrasting environments in South America and Western Europe
(Elsevier, 2017-08)
This study describes and compares the key structural units present in water-soluble organic carbon (WSOC) fraction of atmospheric aerosols collected in different South American (Colombia – Medellín and Bogotá, Peru – Lima, ...
Differences in the composition of organic aerosols between winter and summer in Beijing: a study by direct-infusion ultrahigh-resolution mass spectrometry
(Copernicus gesellschaft MBH, 2020)
This study investigates the chemical composition of PM2.5 collected at a central location in Beijing, China, during winter 2016 and summer 2017. The samples were characterised using direct-infusion negative-nano-electros ...
Local and NON-LOCAL source apportionment of black carbon and combustion generated PM2.5
(Elsevier Ltd, 2024)
Current methods for measuring black carbon aerosol (BC) by optical methods apportion BC to fossil fuel and wood combustion. However, these results are aggregated: local and non-local combustion sources are lumped together. ...
