Journal ArticleDOI
Sugars--dominant water-soluble organic compounds in soils and characterization as tracers in atmospheric particulate matter.
Bernd R.T. Simoneit,Vladimir O. Elias,Minoru Kobayashi,Kimitaka Kawamura,Ahmed I. Rushdi,Patricia M. Medeiros,Wolfgang F. Rogge,Borys M. Didyk +7 more
TL;DR: It is proposed that resuspension of soil (also unpaved road dust) from agricultural activities as a major component of aerosol particles and the saccharides are the source specific tracers.
Journal ArticleDOI
Combustion Products of Plastics as Indicators for Refuse Burning in the Atmosphere
TL;DR: 1,3,5-Triphenylbenzene and tris(2,4-di-tert-butylphenyl)- phosphate were found in detectable amounts in atmospheric samples where plastics and refuse were burned in open fires, and thus it is proposed these two compounds as specific tracers for the open-burning of plastics.
Journal ArticleDOI
Degradation of terrestrially derived macromolecules in the Amazon River
Nicholas D. Ward,Richard G. Keil,Patricia M. Medeiros,Daímio Chaves Brito,Alan Cavalcanti da Cunha,Thorsten Dittmar,Patricia L. Yager,Alex V. Krusche,Jeffrey E. Richey +8 more
TL;DR: In this article, organic matter measurements in the Amazon River suggest that terrestrial macromolecules contribute significantly to this outgassing in tropical and temperate and tropical rivers serve as a substantial source of carbon dioxide to the atmosphere.
Journal ArticleDOI
Analysis of sugars in environmental samples by gas chromatography-mass spectrometry.
TL;DR: The analytical method presented here demonstrated its usefulness for a better understanding of sources and transport of various organic compounds in different environmental compartments and demonstrated its feasibility in detecting several important environmental sugars.
Journal ArticleDOI
Chemical dispersants can suppress the activity of natural oil-degrading microorganisms
Sara Kleindienst,Michael Seidel,Kai Ziervogel,Sharon L. Grim,Kathy M. Loftis,Sarah Harrison,Sairah Y. Malkin,Matthew J. Perkins,Jennifer A. Field,Mitchell L. Sogin,Thorsten Dittmar,Uta Passow,Patricia M. Medeiros,Samantha B. Joye +13 more
TL;DR: Evidence that chemical dispersants applied to either deep water or surface water from the Gulf of Mexico did not stimulate oil biodegradation is provided and it is highlighted that dispersants can exert a negative effect on microbial hydrocarbon degradation rates.
