Excerpt. © Reprinted by permission. All rights reserved. ABSTRACT In-vehicle exposures to particulate matter (PM) and black carbon (BC) can be a significant part of personal total exposure. The purpose of this study was to identify determinants of the in-vehicle pollutant level. This study measured in-vehicle exposure to PM number concentrations using an aerosol spectrometer and BC concentration by an aethalometer. The measurement was repeated 3 times a day for 13 consecutive days in May 2007 while a vehicle was driven on a 1-hr predetermined route in Lexington, KY. The vehicle's windows were closed, its fan was operated at the lowest setting, and air conditioning and heating were off. The average speed of all runs was 37 [+ or -] 5.8 km/hr. Arithmetic mean [PM...

Excerpt. © Reprinted by permission. All rights reserved. ABSTRACT An analysis of fine particulate data in eastern North Carolina was conducted to investigate the impact of the hog industry and its emissions of ammonia into the atmosphere. The fine particulate data are simulated using ISORROPIA, an equilibrium thermodynamic model that simulates the gas and aerosol equilibrium of inorganic atmospheric species. The observational data analyses show that the major constituents of fine particulate matter ([PM.sub.2.5]) are organic carbon, elemental carbon, sulfate, nitrate, and ammonium. The observed [PM.sub.2.5] concentration is positively correlated with temperature but anticorrelated with wind speed. The correlation between [PM.sub.2.5] and wind direction at some locations suggests an impact of ammonia emissions from hog facilities on [PM...

Excerpt. © Reprinted by permission. All rights reserved. ABSTRACT A research site for atmospheric chemistry and air pollution measurements was established at Pinnacle State Park in Addison, NY, in 1995. This paper presents an overview of the site characteristics and measurement program, as well as monthly average concentrations for many of the trace gas and aerosol pollutants over the full measurement period. Monthly averaged ozone concentrations range from values as. low as 15 parts per billion (ppb) during cold-season months, to values approaching 50 ppb during some spring and summer months. Sulfur dioxide ([SO.sub.2]), oxides of nitrogen ([NO.sub.x]) and reactive odd nitrogen ([NO.sub.y]) all show distinct seasonal variation, with summertime monthly averages as low as 1-3 ppb, and wintertime monthly averages...

Excerpt. © Reprinted by permission. All rights reserved. ABSTRACT Speciated coarse particulate matter ([PM.sub.10]) data obtained at three air quality monitoring sites in a highly industrialized area in Spain between 2002 and 2007 were analyzed for assessing source contribution of ambient particulate matter (PM). The source apportionment of PM in this area is an especially difficult task. There are industrial mineral dust emissions that need to be separately quantified from the natural sources of mineral PM. On the other hand, the diversity of industrial processes in the area results in a puzzling industrial emissions scenario. To solve this complex problem, a two-step methodology based on the possibilities of the Multilinear Engine was used. Application of positive matrix factorization to the dataset allowed the identification of...
