Measurements of Atmospheric Radicals
… and environmentally persistent free radicals (EPFR). Many PAH are photoactive and oxidize in the atmosphere into derivatives that can cause more oxidative damage than the parent compounds (oxPAH). Both PAH and EPFR are formed during the combustion process, and both have been suggested as the …

Formation and Stabilization of Combustion-Generated Environmentally Persistent Free Radicals on Transition Metal Oxides Supported on Silica
… This manuscript reports the formation of EPFRs on silica particles containing 5% Fe(III)2O3, Ni(II)O, and Zn(II)O. The EPFRs are formed by the chemisorption of substituted aromatic molecular adsorbates on the metal cation center followed by electron transfer from the adsorbate to the metal …

Formation of Environmentally Persistent Free Radicals on the Surface of Iron Oxide and Interior of Montmorillonite Clay
<p>Environmentally persistent free radicals (EPFRs) are a new class of pollutants known to damage the lungs and heart, as well as catalyze the formation of toxic compounds such as dioxins and furans. EPFRs are known to form on metal oxide nanoparticles’ surface, including iron (III) oxide, and …
