Identification and linkage of tarballs from the coasts of vancouver island and northern california using GC/MS and istophic techniques

摘要

During January and February 1996, a significant number of tarball/ patty incidents occurred along the coasts of Vancouver Island, Washington, oregon, and California. Samples of the tarballs wer collected from the affected beaches and analyzed by gas chromatoraphy/mass spectronetry (GC/MS) and gas chromatography/flame ionization detector (GC/FID) using a tiered analytical approach developed for determining the origin of oils. Selected samples wer further analyzed using a carbon siotopic technique.
