Nuclear techniques have been used to obtain much of the data concerned with inorganic constituents in coal. The data obtained on concentrations of trace and macroelements in coal and fly ash have been studied by several groups in an effort to understand how inorganics are distributed in coal and how they redistribute themselves upon combustion and later in the environment. Among the questions remaining are the chemical species of elements in the ash and how these elements interact with environmental factors such as soil and water. Briefly, Hs, Cl and Br remain completely in the gas phase when coal is burned; As, Cd, Ga, Pb, Se and Zn are concentrated in the fly ash; and 25 other listed elements are incorporated into the slag. Certain other information on trace elements in various coals is given.

Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.

A study has been conducted to identify nonstandard and novel instrumental analysis techniques and to evaluate their potential for development to provide new types of sensors for on-line analysis of coal and for other fossil energy applications. New methods from basic research, and methods used or considered for use in other industries such as mineral and basic metal industries, in petroleum and other well logging, and in biomedical applications have been examined. Particular fossil energy applications have been identified, and equipment requirements and spoolpiece and window requirements for process stream measurements, development status, obstacles to be overcome in development, and other relevant topics have been investigated. Over 60 distinct nuclear techniques (or variations on techniques) have been identified, most of which can be used to determine element concentrations in bulk materials, many of which have potentially significant applicability to coal analysis. The present paper highlights and summarizes some of the more important substantive content abstracted from an extensive and detailed report of the investigation. 9 references, 6 tables.
