Abstract

Environmentally persistent free radicals (EPFRs) are a class of long-lived environmental risk substances that exist in air fine particulate matter (PM_2.5). In the present study, different sample pre-treatment conditions were optimized. The developed method was successfully used to determine the contamination levels of EPFRs in PM_2.5 collected from Zhengzhou in winter. The results will be useful for extensive research on the sources, concentrations, formation mechanisms, physical-chemical characteristics and biological toxicity of EPFRs in the atmosphere.
