Water-Soluble Anions in PM10 Samples Collected in the Metropolitan Area of Costa Rica: Temporal and Spatial Variations
(MDPI journals, 2021-09-28)
The concentrations of water-soluble anions present in PM10 collected from ambient air in
four sites of Costa Rica’s greater metropolitan area (GAM) were analyzed. Samples were collected
over a 24-h period for three days ...
Concentration of PM10 in the Metropolitan Area of Costa Rica, Central America: chemical composition and potential sources
(Universidad Nacional, Costa Rica, 2010)
Measurements of metals and inorganic ions were carried out on PM10. Sampling was made in five sites distributed in San José, Heredia and Belén cities. Samples were collected using Thermo Andersen PM10 high volume samplers ...
Determination of carbonyls and their sources in three sites of the metropolitan area of Costa Rica, Central America
(Springer Science+Business Media B.V, 2011-03-02)
Ambient levels of carbonyl compounds
and their possible sources were studied at three
places in the metropolitan area of Costa Rica,
including a residential, an industrial, and a com mercial downtown area with high ...
Chemical characterization of filterable PM2.5 emissions generated from regulated stationary sources in the Metropolitan Area of Costa Rica
(Elsevier, 2017-01-14)
Filterable PM2.5 concentrations and their chemical characterizations were analyzed for 67 boilers and 25 indirect furnaces located in the Metropolitan Area of Costa Rica from February 2014 to November 2015. The PM2.5 samples ...
Polycyclic aromatic hydrocarbons in PM2.5 and PM10 atmospheric particles in the Metropolitan Area of Costa Rica: Sources, temporal and spatial variations
(Elsevier, 2017-03)
Polycyclic aromatic hydrocarbons (PAHs) concentrations in PM10 and PM2.5 particles were measured at 14 monitoring sites (12 for PM10 and 2 for PM2.5), located in the Metropolitan Area of Costa Rica, from January to November ...
Polycyclic aromatic hydrocarbons in filterable PM2.5 emissions generated from regulated stationary sources in the metropolitan area of Costa Rica
(Elsevier, 2017-09)
This study analyzed the profiles of polycyclic aromatic hydrocarbons (PAHs) in filterable PM2.5 particles collected from a total of 71 boilers and 22 indirect type furnaces that burn liquid and biomass fuels in the ...
