Title: Assessment of highway particulate impacts: Phase 1, Tasks B and C -- Field sampling and evaluation program. Final report, 1991--1997

Abstract

Emissions from unpaved roadways were not targeted for sampling and analysis. This document describes the criteria used to select the field sampling sites, as well as the types of analyses that were performed at those sites. In addition, this document describes the results from the field work component of this study. Chemical mass balance analyses of highway particulate sources were conducted at two sites to determine the contributions of road sanding and salting operations to ambient levels at Albany, NY and at Reno, NV. Finally a set of experiments designed to assess diesel emissions were performed in the Ft. McHenry Tunnel (outside of Baltimore, MD) and in mid-town Manhattan. The Ft. McHenry Tunnel experiment produced emission factor estimates for heavy-duty diesel emission sources. Chemical mass balance analyses were performed in mid-town Manhattan to assess the contribution to ambient levels resulting from urban bus traffic. Results from the field work phase showed that paved road resuspension and road sanding and salting operations contribute significantly to the ambient levels, in the absence of other sources, contributing, in some cases, up to 60 percent of the total mass collected on the filters. In mid-town Manhattan, diesel emissions also contribute significantly to ambient levels;more » however, the emission factor results from the Ft. McHenry Tunnel indicated that emission from heavy-duty diesels were lower than published emission factors by approximate 50 percent.« less
