Since ingestion of foods is considered a major source of pollutant intake by man, the knowledge of detailed food consumption patterns is necessary to determine health risks and compliance with regulatory standards. As currently-available literature lacks data necessary for complete evaluation of aquatic foods via human consumption of fish and shellfish, a review of recent surveys of fish consumption in the U.S. was performed. The data in these surveys were subjected to statistical analysis to determine percentage distributions of individuals eating different quantities of marine and freshwater fish and shellfish. Included are surveys on consumption of sportfish from the Columbia River (Ho71) and Lake Michigan areas (Hu78) and a comprehensive study of fish consumption in the nine census regions of the U.S. . The results of these studies indicate that the quantity, as reported, of each type of fish eaten increases as a function of the age of consumers. Regional differences are most apparent in the use of shellfish and freshwater fish. About 94% of children and %lo% of adults eat some kind of fish with a per capifa average of 4.97 kglyr. Since this quantity is on an actual consumption basis. as opposed to "as purchased", the per capita consumption rate is lower than usually reported in the literature.

For the first time, plutonium retention in human upper airways was investigated based on the dosimetric structure of the human respiratory tract proposed by the International Commission on Radiological Protection (ICRP). This paper describes analytical work methodology, case selection criteria, and summarizes findings on soluble (ICRP 68 Type M material) plutonium distribution in the lungs of a former nuclear worker occupationally exposed to plutonium nitrate [Pu(NO)]. Thirty-eight years post-intake, plutonium was found to be uniformly distributed between bronchial (BB), bronchiolar (bb) and alveolar-interstitial (AI) dosimetric compartments as well as between the left and right lungs. Pu andPu total body activity was estimated to be 2333 ± 23 and 42.1 ± 0.7 Bq, respectively. The results of this work provide key information on the extent of plutonium binding in the upper airways of the human respiratory tract.

Furfuryl chloride has been isolated in a pure state, analyzed and its physical properties have been determined. It is a relatively unstable substance but of sufficient stability to be distilled in a vacuum and used in a variety of reactions. It seems obviously more stable than the corresponding bromide and iodide. This is the first time the parent -halogen methyl ftiran has been obtained in a pure, free condition, having previously been known only in solution.2. The chlorine atom possesses a high order of reactivity, comparable to that of the chlorine in benzyl chloride. Eight ethers have been prepared from the -furfuryl chloride and their physical properties determined.The allyl-a-furfuryl ether has been prepared by the direct reaction between the chloride and allyl alcohol.3. The synthesis of this reactive chloride has opened up new possibilities in the furan series and investigations of other reactions using -furfuryl chloride are being continued.
