Comparisons are made of C (sub2)-C (sub12) volatile organic compounds (VOCs) concentrations measured at two Houston air monitoring sites in 1978 and 2000. In 1978 ambient air was collected in Tedlar bags during the 0600-0900 and 1300-1600 time periods at the Mae Drive and Crawford Road sites as part of a large study to collect data for ozone model development. In 2000 ambient air samples were collected in Summa canisters at the same two sites during the same 3-h periods in conjunction with another large study with similar goals. VOC concentrations and compositions are compared to examine similarities and differences between 1978 and 2000.
