Objective:
To assess inter-community variability of vehicular-related emissions across Southern California, and to potentially link the variability of specific reactive compounds in ambient air to observed patterns of respiratory health in Southern California children, Center investigators have embarked on an ambient polycyclic aromatic hydrocarbons (PAHs)/carbonyls/quinones sampling study. Field operations are being conducted in 12 Southern California communities to collect 24-hour samples, approximately once per week on differing days, to develop seasonal profiles of PAHs, aldehydes, and quinones for the 12 communities participating in the CHS. Center investigators expect that inter-community variability of specific organics, carbonyls, and quinones monitored in the study may help to disentangle previously observed correlated associations between gaseous entities, particle pollutants, and several respiratory health outcomes of California school children.
Progress Summary:
Samplers were deployed in Spring 2001 for actual data collection. Data available for the first sampling cycle (May-July 2001) suggest a regional transitional increase in quinones across the initial sampling sites, with a several-fold increase across communities in two of four quinones and virtually no change regionally in a third quinone (Figures 1a and 1b). Ambient napthalene concentrations varied from 86 to 650 nanograms per cubic meter, with Los Angeles basin (LAB) sites having higher observed levels. Other semivolatile PAHs varied in levels and order across the sites.

Source site – Site where little atmospheric chemistry is anticipated.
Receptor site – Site on eastern side of Los Angeles Basin where chemistry is expected.
Field operations continued at Lompoc, Upland, and Mira Loma from August through October 2001; those data are currently being analyzed. During November and December 2001, sampling was conducted at the initial three sampling sites (Atascadero, San Dimas, and Riverside). In January 2002, samplers were once again re-located to Lompoc, Upland, and Mira Loma and will remain there for the January/February 2002 sampling period.
Future Activities:
Alternating 2-month periods of sampling will continue between these two sets of three Southern California communities through May 2002. Sampling at the remaining six Children’s Health Study (CHS) sites is planned for mid-2002 through 2003. In this manner, we plan to develop seasonal information about inter-community PAH, carbonyls, and quinones in a cost-effective, logistically feasible, and scientifically credible protocol. The data will then be used in ongoing analyses of health outcomes for the CHS study and toxicological endpoints of interest in animal studies planned for several locations across LAB.
