Chloroform (CHCl3) is used in industry and laboratory settings as a solvent for adhesives, pesticides, fats, oils and rubbers. It is also used as a chemical intermediate in the synthesis of fluorocarbon 22, dyes, pesticides, and tribromomethane. Chloroform is produced as a byproduct of water, sewage, and wood pulp chlorination (HSDB, 1995). In 1996, the latest year tabulated, the statewide mean...

Air toxic emissions from on-road mobile sources are significant contributors to the degradation of air quality in urban and dense population centers. Research led by United States Environmental Protection Agency (EPA) identified more than 1162 hazardous pollutants (HAPs) exhaust evaporative sources. However, less 70 monitored regulatory agencies. HAPs emitted Mobile Sources known as Source Toxi...

To explore intra-ethnic diversity in patterns of environmental health injustice inMiami (Florida), we relatedmodeled estimates of cancer risks from on-road pollutants from the 2005 National-scale Air Toxics Assessment with 2005–2009 American Community Survey tract-level sociodemographic data. Neighborhoods with lower incomes and higher proportions of Hispanics were at risk.When disaggregating ‘...

The current requirements and status of air quality modeling of hazardous pollutants are reviewed. Many applications require the ability to predict the local impacts from industrial sources or large roadways as needed for community health characterization and evaluating environmental justice concerns. Such local-scale modeling assessments can be performed by using Gaussian dispersion models. How...

The Benzene and other Toxics Exposure (BEE-TEX) field study was an experimental campaign designed to demonstrate novel methods for measuring ambient concentrations of hazardous air pollutants (HAPs) in real time and to attribute these concentrations to quantified releases from specific emission points in industrial facilities while operating outside facility fence lines. BEE-TEX was conducted i...
