Chemical and morpho-structural characterization of atmospheric aerosol (PM and PM) in a city of São Paulo state, Brazil.

To access the sources of air pollutants is crucial to control atmospheric pollution in urban areas, minimizing human exposure. Particulate matter is a pollutant of great concern making its chemical and morpho-structural characterization of enormous importance. The present work aims at the characterization of atmospheric PM and PM.

Characterization of atmospheric aerosol (PM and PM) from a medium sized city in São Paulo state, Brazil.

Air pollution causes deleterious effects on human health with aerosols being among the most polluting agents. The objective of this work is the characterization of the PM and PM aerosol mass in the atmosphere. The methods of analysis include WD-XRF and EDS.

PARAFAC HPLC-DAD metabolomic fingerprint investigation of reference and crossed coffees.

In this study two cultivars of Coffea arabica L., Bourbon (reference) and IPR101 (crossing) were analyzed. The extracts were prepared according to a simplex centroid design with four components, ethanol, ethyl acetate, dichloromethane, and hexane.
