In-Mine Measurement of Reactive Diesel Exhaust Contaminants

摘要

This report documents laboratory and in-mine analyses of diesel exhaust pollutants carried out to assess the fate of potentially reactive species in a mine environment. Specifically, the concentration of stable compounds including carbon monoxide and carbon dioxide, and potentially reactive compounds including nitric oxide, nitrogen dioxide, sulfur dioxide, aldehydes, formaldehyde, acrolein, formic acid, odorants, particulates, soluble sulfates, and polynuclear aromatic hydrocarbons were determined. The concentration and mass emission rates of these compounds were measured in the laboratory under three engine speed and load conditions and with three exhaust control conditions; that is, none, catalyst, and water conditioner.
