A procedure for estimating total organochlorine pesticide and PCB residue in seal blubber at concentrations of greater than 1μg g-1 of lipid is described. Lipid is cleaned up by alumina column chromatography, and the halogen concentration of the resulting hexane eluace is determined by combustion and microcoulometry. Results are similar to those obtained by gas chromatographic analysis and can be used to interpolate between results so obtained when data on specific organochlorine compounds is not required for each sample. The organochlorine residues recovered in this manner did not constitute all the halogen determined by combustion and microcoulometry of seal lipid. Analysis by the total halogen procedure was 2.5 tunes faster than the rate achieved with a combination of liquid and gas chromatography operated manually; the requirements for laboratory equipment and space for sample preparation are reduced.
