The Pueblo Chemical Depot, located east of Pueblo, CO, is typical of a number of U.S. facilities that were involved in weapons manufacturing, training and testing, or demilitarization in which the soil and groundwater became highly contaminated with

In this study, atomic force microscopy (AFM) was evaluated as an alternative to electron microscopy for analysis of nano- to micron-sized environmental particles, such as atmospheric aerosols. The wide range of conditions under which AFM can be condu

A new approach to the measurement of the size distribution of atmospheric particles as a function of chemical reactivity is demonstrated. In this method, particles are collected on an atomically flat mica substrate and imaged using atomic force micro

The derivatizing reagent 2,4,6-trichlorophenylhydrazine (TCPH) was applied for the first time to the determination of atmospheric aldehydes and ketones using gas chromatography (GC) with electron-capture detection. TCPH is volatile enough to be used

Peroxyoxalate chemiluminescence, the most efficient nonenzymatic chemiluminescence reaction known, is used to demonstrate mechanistic features of analogous ester hydrolysis reactions. The effect of the leaving group pKa and a comparison between nucle
