In certain areas of the country where the National Ambient Air Quality Standard for ozone is being exceeded, additional measurements of ambient nonmethane organic compounds (NMOC) are needed to assist the affected states in developing revised ozone control strategies. Because of previous difficulty in obtaining accurate NMOC measurements, the U.S. Environmental Protection Agency (EPA) has provided monitoring and analytical assistance to these states through Radian Corporation. This assistance began in 1984 and continues through the 1988 NMOC Monitoring Program. Between April 18 and October 30, 1988, Radian analyzed 3,497 ambient air samples, collected at 45 sites. These NMOC analyses were performed by the cryogenic preconcentration, direct flame ionization detection (PDFID) method. Based on 1984, 1985, 1986, and 1987 studies, the method was shown to be precise, accurate, and cost effective relative to the capillary column gas chromatographic, flame ionization detection (GC/FID) method. In 1987 Radian Corporation developed a gas chromatographic multidetector (GC/MD) method to determine the concentration of 38 selected toxic compounds in ambient air. In 1988, air toxic analyses were conducted by GC/MD on ambient air samples taken at 13 sites at which NMOC samples were taken. The 1988 Urban Air Toxics Monitoring Program (UATMP) began in October 1987 at 19 urban sites and extended through September 1988.
