Method comparisons of vehicle emissions measurements in the fort mchenry and Tuscarora mountain tunnels
Gary A. Bishop,Scott E. McLaren,Donald H. Stedman,William R. Pierson,Roy B. Zweidinger,William D. Ray +5 more
TL;DR: In this article, the first reported measurements of individual vehicle exhaust in tunnels by a remote sensing device (RSD) were compared to integrated emission measurements carried out by analysis of concurrent collections of tunnel air into bags, canisters, and adsorbent traps and by conventional Fourier transform infrared (FTIR) spectroscopy.
Journal ArticleDOI
Mutagenic and carcinogenic potency of extracts of diesel and related environmental emissions: Study design, sample generation, collection, and preparation
Joellen Lewtas,Ronald L. Bradow,R.H. Jungers,B.D. Harris,Roy B. Zweidinger,K.M. Cushing,B.E. Gill,R.E. Albert,R.E. Albert +8 more
TL;DR: A major diesel emissions research program has been initiated by the U.S. Environmental Protection Agency to assess the human health risk associated with increased use of diesel automobiles as mentioned in this paper, which is intended to establish the mutagenic and carcinogenic potency of complex organics associated with diesel particles as well as comparative particle-bound organics from other environmental emissions.
Journal ArticleDOI
Apportionment of residential indoor aerosol, VOC, and aldehyde species to indoor and outdoor sources, and their source strengths
TL;DR: The average concentrations of 45 fine-particle aerosol, VOC and aldehyde species measured in 10 Boise, ID, residences in wintertime have been apportioned according to their contributions from all inside sources and all outside sources.
Journal ArticleDOI
The 1999 Fresno Particulate Matter Exposure Studies: Comparison of Community, Outdoor, and Residential PM Mass Measurements
Gary F. Evans,Ross V. Highsmith,Linda Sheldon,Jack C. Suggs,Ronald Williams,Roy B. Zweidinger,John P. Creason,Debra Walsh,Charles Rodes,P.A. Lawless +9 more
TL;DR: Two collaborative studies have been conducted by the U.S. Environmental Protection Agency (EPA) and National Exposure Research Laboratory (NERL) to determine personal exposures and physiological responses to par-ticulate matter (PM) of elderly persons living in a retirement facility in Fresno, CA.
Journal ArticleDOI
Characterization of indoor and outdoor air associated with residences using woodstoves: A pilot study
TL;DR: Particulate, semivolatile organic compound, volatile organic compound (VOC), and aldehyde samples were simultaneously collected during two nighttime 12-hour sampling periods at three Raleigh, NC, residences with operating woodstoves during February 1985 as mentioned in this paper.
