Sediments from 22 sites in the Raritan Bay-Lower New York Bay complex showed that extractable hydrocarbons and percent volatiles increased as the silt-clay content of the sediment increased. The hydrocarbons appeared to be concentrated in the deeper center of Raritan Bay and the Raritan Bay muds, heading down the Bay towards Sandy Hook. Extractable hydrocarbons ranged from 2.2-1098.2 micrograms/g of dry sediment and the percent of volatiles ranged from 0.85-11.39. A peak within the n-C23 range and a large 'unresolved complex mixture' were characteristic of gas chromatograms. Mixed isomers of benz-pyrene and benz-anthracence and unidentified 1-6 ring polynuclear aromatic hydrocarbons were present.
