Identification of polycyclic aromatic hydrocarbons in sugar cane soot by gas chromatography mass spectrometry
(Vieweg, 1997-12-01)
Fly soot samples collected in the sugar cane fields after the process of burning were extracted in a Soxhlet apparatus (methylene chloride:methanol 4:1). The extracts were fractionated on silica gel Sep-Pak cartridges into ...
Possibilities of reusing sugar cane straw ash in the production of alternative binders
(2016-01-01)
Sugar cane production is increasing in Brazil due the demand in manufacturing sugar and alcohol. During production process, several wastes are generated, such as sugar cane straw. After a burning process of this waste ...
Diurnal and nocturnal measurements of PAH, nitro-PAH, and oxy-PAH compounds in atmospheric particulate matter of a sugar cane burning region
(Elsevier B.V., 2014-02-01)
Polycyclic aromatic hydrocarbons (PAHs), nitro-PAHs, and oxy-PAHs were studied in the atmospheric particulate matter of a subtropical rural region (Sao Paulo State, Brazil) affected by emissions from sugar cane burning. ...
Characterisation of sugar cane combustion particles in the Araraquara region, Southeast Brazil
(Springer, 2004-04-01)
Biomass burning is an important primary and secondary source of aerosol particles. The presence of carbonaceous particles in the respirable size range makes the study of this fraction important in view of possible health ...

Comparative respiratory toxicity of particles produced by traffic and sugar cane burning
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
The impact of particle emissions by biomass burning is increasing throughout the world. We explored the toxicity of particulate matter produced by sugar cane burning and compared these effects with equivalent mass of ...
Influence of sugar cane burning on aerosol soluble ion composition in Southeastern Brazil
(Elsevier B.V., 2004-09-01)
Seasonal variability in the major soluble ion composition of atmospheric particulate matter in the principal sugar cane growing region of central São Paulo State indicates that pre-harvest burning of sugar cane plants is ...

Greenhouse gas emission associated with sugar production in southern Brazil
(2010-06-17)
Background: Since sugarcane areas have increased rapidly in Brazil, the contribution of the sugarcane production, and, especially, of the sugarcane harvest system to the greenhouse gas emissions of the country is an issue ...
