Characterization of the dust/smoke aerosol that settled east of the World Trade Center (WTC) in lower Manhattan after the collapse of the WTC 11 September 2001.
The results support the need to have the interior of residences, buildings, and their respective HVAC systems professionally cleaned to reduce long-term residential risks before rehabitation. Expand
This paper develops hypotheses regarding the interactions among stress, immunity, and chemical sensitivities and gives an overview of the questions and hypotheses generated by a working groupExpand
Influence of ambient (outdoor) sources on residential indoor and personal PM2.5 concentrations: Analyses of RIOPA data
The mean of the distribution of ambient contributions across study homes agreed well for themass balance and RCS models, but the distribution was somewhat broader when calculated using the mass balance model with measured air exchange rates. Expand
Polycyclic aromatic hydrocarbons in the indoor and outdoor air of three cities in the U.S.
The indoor and outdoor concentrations of 30 polycyclic aromatic hydrocarbons were measured in 55 nonsmoking residences in three urban areas during June 1999-May 2000 and showed that indoor sources had a significant effect on indoor concentrations of 3-ring PAHs and a smaller effect on 4-rings and that outdoor sources dominated the indoor concentrations.

Relationships of Indoor, Outdoor, and Personal Air (RIOPA). Part I. Collection methods and descriptive analyses.
The results show that indoor sources dominated personal and indoor air concentrations of many measured VOCs and carbonyl compounds, and associations derived from or models based on this data set that may link the influence of outdoor sources with indoorAir toxics and PM2.5 can be relevant to other urban settings.

Percutaneous absorption of trihalomethanes, haloacetic acids, and haloketones.
A direct relationship was found between the permeability of THMs, but not HKs and HAAs, and their octanol/water partition coefficients and dermal absorption is an important route of exposure to THMs andHKs and must be considered in models of risk assessment. Expand

  • 1 December 1990
The mean internal dose due to dermal exposure was found to be approximately equal to that due to the inhalation exposure, and the effect of the showering activities on the concentration of chloroform shower air was examined. Expand
Exposure estimates to disinfection by-products of chlorinated drinking water.
Using water concentration as an exposure estimate can introduce misclassification of exposure for DBPs whose primary route is ingestion due to the great variability in the amount of water ingested across a population. Expand
Simultaneous and sensitive measurement of anabasine, nicotine, and nicotine metabolites in human urine by liquid chromatography-tandem mass spectrometry.
This sensitive LC/MS/MS procedure can be used to determine nicotine metabolism profiles of smokers, people during nicotine replacement therapy, and passively exposed nonsmokers. Expand
Relationship of Indoor, Outdoor and Personal Air (RIOPA) study: study design, methods and quality assurance/control results
The results from the RIOPA study can potentially provide information on the influence of ambient sources on indoor air concentrations and exposure for many air toxics and will furnish an opportunity to evaluate exposure models for these compounds. Expand
