Accurate assessment of human exposures is an important part of environmental health effects research. However, most air pollution epidemiology studies rely upon imperfect surrogates of personal exposures, such as information based on available central-site outdoor concentration monitoring or modeling data. In this paper, we examine the limitations of using(More)
Modeling of inhalation exposure and risks resulting from exposure to mobile source air toxics can be used to evaluate impacts of reductions from control programs on overall risk, as well as changes in relative contributions of different source sectors to risk, changes in contributions of different pollutants to overall risk, and changes in geographic(More)
Projecting a hazardous air pollutant (HAP) emission inventory to future years can provide valuable information for air quality management activities such as prediction of program successes and helping to assess future priorities. We have projected the 1999 National Emission Inventory for HAPs to numerous future years up to 2020 using the following tools and(More)
Previously it was shown that the acute administration of ethanol to the rat significantly alters the metabolism of the dopamine (DA) in liver but not in brain tissue. To extend this finding to the primate, two push-pull perfusion cannulae were implanted in the regions of the left and right caudate nucleus of a Macaca nemistrina. After 14C-DA was injected(More)
A hybrid air quality model has been developed and applied to estimate annual concentrations of 40 hazardous air pollutants (HAPs) across the continental United States (CONUS) to support the 2011 calendar year National Air Toxics Assessment (NATA). By combining a chemical transport model (CTM) with a Gaussian dispersion model, both reactive and nonreactive(More)
A large body of literature published in recent years suggests increased health risk due to exposure of people to air pollution in close proximity to roadways. As a result, there is a need to more accurately represent the spatial concentration gradients near roadways to develop mitigation strategies. In this paper, we present a practical, readily adaptable(More)
The effect of tetraethylthiuramdisulfide (disulfiram) on the catabolism of dopamine within discrete regions of the brain was investigated in the unrestrained rat. After a guide cannula had been implanted stereotaxically, a given subcortical site was radiolabeled with 14C-dopamine (DA) by microinjecting 2.0 mu Ci in 2.0 microliters. Successive push-pull(More)
Based on previous studies of heavy orographic precipitation events which have occurred over the US (e.g. Maddox et al. 1978; Pontrelli et al. 1999) and southern Alps (e.g. Buzzi and Foschini 2000; Massacand et al. 1998), Lin et al. (2001) summarized that the synoptic and mesoscale environments conducive to heavy orographic rainfall in the Alps are: (1) a(More)
