On-line analysis of reactive VOCs from urban lawn mowing
Article Abstract:
In the area of Innsbruck, Austria, volatile organic compounds (VOCs) from lawn mowing in July and August 1998 were measured in this study. VOCs have an effect on the formation of atmospheric oxidants such as ozone. VOCs from lawn mowing have the same impact on the atmosphere as unburned hydrocarbons created by mowing by gasoline-powered lawn mowers, and should be considered in urban air-quality programs.

Source appointment of urban particulate aliphatic and polynuclear aromatic hydrocarbons using multivariate methods
Article Abstract:
An activated-charcoal diffusion denuder was utilized on samples of organic aerosol collected in Santiago de Chile in order to strip out organic vapors before particle collection. Gas chromatography/mass spectrometry was used to determine aliphatic hydrocarbons and polynuclear aromatic hydrocarbons (PAHs). PAHs have been focused on for many years because of their mutagenic and carcinogenic properties.

Dynamic mathematical model for the biodegradation of VOCs in a biofilter: biomass accumulation study
Article Abstract:
Mathematical modeling of processes in a packed trickle-bed air biofilter shows that a drop in removal efficiency may be observed when the amount of biomass accumulates in the reactor and causes a drop in the diffusion rate. Three reactor porous medium models were evaluated and results show that spheres and pipes were proven superior over parallel plates in explaining volatile organic compound removal rates and biofilter system performance.
