Non-Methane Organic Compound (NMOC) and Speciated Non-Methane (SNMOC) sample collection systems were used to collect ambient air in eight areas from June through September where the National Ambient Air Quality Standards (NAAQS) for ozone may by exceeded. The NMOC and SNMOC program generally consists of several activities that include site coordination, equipment certification, installation, sample analysis, data reduction, validation and reporting, statistical analyses and data characterization, and formatting and submittal of the validation data to the Aerometric Information Retrieval System (AIRS). Non-methane hydrocarbons are reported for the base NMOC program. Seventy-eight compounds were targeted for the speciated NMOC base program and the speciated option to the NOC base program; thirty-eight compounds were targeted for the toxics option, and sixteen compounds were targeted for the carbonyls option. Statistical analysis includes number of occurrences, frequency percent, maximum, minimum, median, and mean concentrations. Standard deviation, skewness, and kurtosis are reported for the speciated, toxics, and carbonyl options. Sites in Long Island, New York, Newark and Plainfield, New Jersey, Birmingham, Alabama, and Fort Worth and El Paso, Texas, participated in the various programs and options.
