"November 1989." Includes bibliographical references. "This manuscript describes an analytical method for the detection land quantitation of polychlorinated biphenyls and polychlorinated terphenyls in spiked sediment samples at ppm levels. Results indicate that microbore columns could be a better alternative to open tubular columns because they can handle a greater loading of analytes. UV-detector has no advantage over the flame ionization detector as far as sensitivity is concerned but can eliminate some interfering analytes that do not absorb at 208 nm"--Management Perspective. gccst Sediments gccst Water pollution Canada.
