Nonmethane Organic Compounds (NMOC) and Speciated Nonmethane Organic Compounds (SNMOC) Monitoring Program, 2001

摘要

This report summarizes and interprets ambient air monitoring data collected during the summer of 2001 as part of the National Nonmethane Organic Compound and Speciated Nonmethane Organic Compound Monitoring Program, which is also called the NMOC/SNMOC Monitoring Program. Designed to characterize levels of air pollution in regions with ground-level ozone problems, the NMOC/SNMOC Monitoring Program measures air concentrations of several groups of pollutants that contribute to the photochemical reactions that form smog. The 2001 NMOC/SNMOC Monitoring Program spanned four months (June to September), during which ambient air samples were collected daily between 6:00 a.m. and 9:00 a.m., local time, at two monitoring locations. These samples were analyzed for NMOC and SNMOC. Overall, over 8,600 ambient air concentrations were measured during the 2001 program.
