Lindaas et al. measured the influence of transported biomass burning smoke on atmospheric composition in the Colorado Front Range. Their study included measurements for an impressive range of compounds, including VOCs, reactive nitrogen, and ozone; the field work seems to have been carefully performed. The authors assessed several meteorological variables and determined that they were not the c...

The troposphere, the region of the Earth’s atmosphere in which we live and breath, is composed of many different kinds of gases. These components range from the abundant two-atom molecules O2 and N2, to larger and more reactive chemicals, which include vast numbers of different volatile organic compounds (VOCs). Concentrations of VOCs can be as high as one part per million by volume (10 , or pp...

The use of polymer coated surface acoustic wave (SAW) sensor arrays is a very promising technique for highly sensitive and selective detection of volatile organic compounds (VOCs). We present new developments to achieve a low cost sensor setup with a sampling method enabling the highly reproducible detection of volatiles even in the ppb range. Since the VOCs of coffee are well known by gas chro...

This study evaluated exposures among vehicle repair technicians to hexane, acetone, toluene, and total volatile organic compounds (VOCs). On randomly selected workdays, we observed a characteristic pattern of solvent use among 36 technicians employed in 10 repair shops, each of which used an aerosol solvent product. We obtained quantitative exposure measurements from a subset of nine technician...

Lung cancer is a leading cause of deaths in cancer. Hence, developing early-stage diagnostic tests that are non-invasive, highly sensitive, and specific is crucial. In this study, we investigated to determine whether biomarkers derived from urinary volatile organic compounds (VOCs) can be used to discriminate between lung cancer patients and normal control patients. The VOCs were extracted from...

A total of 130 volatile organic compounds (VOCs) and 14 carbonyls were measured at the Jasso (JAS) Tepeji (TEP) sites during warm-dry season 2006 in Tula, Hidalgo, Mexico, a highly industrialized area with more than 120 industries. These data compared those obtained Mexico City 2012 an urban center (Merced, MER) site southwest residential (Pedregal, PED) site. Average VOC concentrations Tula do...

15 We analyze a photochemical smog episode to understand the oxidative capacity and radical chemistry of the polluted atmosphere in Hong Kong and the Pearl River Delta (PRD) region. A photochemical box model based on the Master Chemical Mechanism (MCM v3.2) is constrained by an intensive set of field observations to elucidate the budgets of ROX (ROX=OH+HO2+RO2) and NO3 radicals. Highly abundant...

Volatile organic compounds (VOCs) are major pollutants that are found in contaminated sites, particularly in developed countries such as Japan. Various microorganisms that degrade individual VOCs have been reported, and genomic information related to their phylogenetic classification and VOC-degrading enzymes is available. However, the biodegradation of multiple VOCs remains a challenging issue...
