Extractable organohalogens (EOX) are organic compounds that contain chlorine, bromine and/or iodine, which can be separated from the matrix by liquid/liquid or liquid/solid extraction. A combination of instrumental neutron activation analysis (INAA) and solvent extraction methods has been developed for the determination of EOX from the shrimp Pandalus borealis. Levels of EOX were evaluated for spatial trends for shrimp caught in several areas off the Labrador coast, off the coast of Nova Scotia, and off the coast of Maine. Muscle contained 1.09-6.05 mu g EOCl/g tissue and 105-498 mu g extractable organochlorine (EOCl)/g lipid; 0.0607-0.288 mu g extractable organobromine (EOB)r/g tissue and 4.74-10.5 mu g EOBr/g lipid; and 0.014-0.048 mu g extractable organoiodine (EOI)/g tissue and 1.03-1.76 mu g EOI/g Lipid, respectively. The levels of EOCl in roe were 1.60-12.34 mu g/g tissue and 39.0-146 mu g/g lipid. In roe, the EOBr levels were 0.707-1.03 mu g/g tissue and 6.96-13.5 mu g/g lipid; and EOI levels were 0.123-0.349 mu g/g tissue and 1.42-4.11 mu g/g lipid. The EOCl, EOBr, and EOI levels in roe increased noticeably from north to south along the coast of Labrador. Samples taken from the coast of Maine and from Canso Hole were typically higher in EOCl levels than those taken from Labrador. The results for EOBr and EOI were in the same range as those from Labrador.
