Analysis of Selected Volatile Organic Substances in Ambient Air

摘要

This report is part of the first phase of the State of New Jersey's multi-year investigation into toxic/carcinogenic air contaminants. It reports the development of sampling/analytical methodologies and laboratory techniques in determining the concentrations of selected volatile organic substances in the vapor phase through use of GC/FID and GC/MS/Computer techniques. A total of 330 samples were collected in portions of northern New Jersey using tubes packed with adsorbent materials to preconcentrate the target compounds. Samples were analyzed for benzene, carbon tetrachloride, chloroform, o- and p-dichlorobenzene, 1,2-dichloroethane, nitrobenzene, tetrachloroethylene, 1,1,1-trichloroethane, trichloroethylene, and vinyl chloride. Full data sets for all samples are appended to the report. A summary report discussing general levels and information regarding the selected compounds is also available.
