Ozone formation potentials of volatile organic compounds and ozone sensitivity to their emission in the megacity of Sao Paulo, Brazil
(SPRINGER, 2008)
In the present study, a three-dimensional Eulerian photochemical model was employed to estimate the impact that organic compounds have on tropospheric ozone formation in the Metropolitan Area of Sao Paulo (MASP). In the ...
Photochemical ozone pollution in the Valparaiso Region, Chile
(Springer Science and Business Media Netherlands, 2014)
The Valparaiso Region is characterized by the presence of air sheds that modulate the general atmospheric circulation with local winds. The ozone concentration in the region increases from the west coast toward the mountainous ...
Development of a sensitive passive sampler using indigotrisulfonate for the determination of tropospheric ozone
(Royal Soc Chemistry, 2010-01-01)
A new sampling and analytical design for measurement of ambient ozone is presented. The procedure is based on ozone absorption and decoloration (at 600 nm) of indigotrisulfonate dye, where ozone adds itself across the ...

Ozone weekend effect in Santiago, Chile
(Elsevier Ltd., 2011-10-12)
The study examined weekdayeweekend differences in ozone, NOx (NO and NO2) and VOC concentrations
in Santiago, Chile, from 1999 to 2007. The results provide evidence for the occurrence of an
atmospheric phenomenon that ...
CeO(2)-catalyzed ozonation of phenol
(SPRINGER, 2010)
Three different cerium citrate-based precursors were used for synthesizing CeO(2) through thermal treatment. Three morphological types of CeO(2) were obtained. Characterization of these oxides was carried out by XRD patterns, ...
