Particle concentrations in inner-city homes of children with asthma: the effect of smoking, cooking, and outdoor pollutionLance A Wallace
U S Environmental Protection Agency, Reston, Virginia 20191 4471, USA
Environ Health Perspect 111:1265-72. 2003....
Use of personal-indoor-outdoor sulfur concentrations to estimate the infiltration factor and outdoor exposure factor for individual homes and personsLance Wallace
National Exposure Research Laboratory, US EPA, Research Triangle Park, North Carolina, USA
Environ Sci Technol 39:1707-14. 2005..The regressions had R2 values ranging from 0.19 to 0.88 (median = 0.73). These values provide an indication of the extent of misclassification error in epidemiological estimates of the effect of outdoor particles on health...
Continuous monitoring of ultrafine, fine, and coarse particles in a residence for 18 months in 1999-2000Lance Wallace
National Exposure Research Laboratory, U S Environmental Protection Agency, Reston, Virginia 20192, USA
J Air Waste Manag Assoc 52:828-44. 2002..8 air changes per hour (hr(-1))], particle concentrations were either elevated (when no source was present) or depressed (when an indoor source was operating) by factors of up to 2 compared with low air change rates...
Source strengths of ultrafine and fine particles due to cooking with a gas stoveLance A Wallace
U S Environmental Protection Agency, 11568 Woodhollow Court, Reston, Virginia 20191, USA
Environ Sci Technol 38:2304-11. 2004....
The effect of opening windows on air change rates in two homesCynthia Howard-Reed
National Exposure Research Laboratory, U S Environmental Protection Agency, Reston, Virginia, USA
J Air Waste Manag Assoc 52:147-59. 2002..Results of this study indicate the importance of occupant window-opening behavior on a home's air change rate and the consequent need to incorporate this factor when estimating human exposure to indoor air pollutants...
Monitoring and reducing exposure of infants to pollutants in house dustJohn W Roberts
US Environmental Protection Agency, Reston, VA 22091, USA
Rev Environ Contam Toxicol 201:1-39. 2009..We believe that proven intervention methods can reduce the exposure of infants to pollutants in house dust, while recognizing that much remains to be learned about improving the effectiveness of such methods...
Volatile organic compounds as breath biomarkers for active and passive smokingSydney M Gordon
Battelle Memorial Institute, Columbus, Ohio 43201, USA
Environ Health Perspect 110:689-98. 2002..5 (1,3-butadiene) to 0.9 min (benzene) for tau1 and were essentially constant (14 min) for tau2. These findings will be useful in models of environmental tobacco smoke exposure and risk...
Real-time indoor and outdoor measurements of black carbon in an occupied house: an examination of sourcesLaura E LaRosa
Johns Hopkins University Bloomberg School of Public Health, Division of Environmental Health Engineering, Baltimore, Maryland, USA
J Air Waste Manag Assoc 52:41-9. 2002..An artifact associated with the tape advance was noted for the aethalometer, but a correction factor was developed that reduced the associated error by a factor of 2...
Validation of a method for estimating long-term exposures based on short-term measurementsLance Wallace
National Exposure Research Laboratory, U S Environmental Protection Agency, Research Triangle Park, NC 27711, USA
Risk Anal 25:687-94. 2005..Although the method assumes a log-normal distribution, most of the distributions tested failed the chi-square test for log-normality. Therefore, the method appears suitable for application to distributions that depart from log-normality...
