C1-C5 organic acid emissions from an SI engine: influence of fuel and air/fuel equivalence ratio
Article Abstract:
Exhaust emissions from a spark ignition engine run on fuel of various compositions are analyzed for alcohols, aldehydes, and organic acids. Graphs show emissions of acetic acid, formic acid, propionic acid, butyric acid, acrylic acid, and isovaleric acid for each type of gasoline.

Analysis of organic esters of plasticizer in indoor air by GC-MS and GC-FPD
Article Abstract:
Indoor air samples are taken in contemporary Japanese homes using charcoal samples and gas chromatography-mass spectrometer and flame photometric detector methods to determine levels of air pollution from phthalate and phosphate esters. The procedural limits and precision are charted with the results, proving the sampling and detection methods to be valid; and measured levels of the contaminants are high enough to rationalize further tests.

Distributions of indoor and outdoor air pollutants in Rio de Janeiro, Brazil: implications to indoor air quality in bayside offices
Article Abstract:
The use of ethanol and other gasoline blends in Rio de Janeiro, Brazil, has been found to induce a significant increase in the level of formaldehyde in the atmosphere. Results gathered from four office sampling sites further revealed that the indoor level of total volatile organic compounds (TVOC) is relatively high in upper floors. The amount of total suspended particles (TSP) in the atmosphere exceeded the level embodied in the Brazilian Legislation.
