“…The literature reports adequate desorption at temperatures as low as 300 °C' and incomplete desorption for temperatures as high as 450 °C 2 (this same paper then presents a figure that appears to have adequate desorption at 400 °C ). Other reports use desorption temperatures ranging from 500 to 800 OQ 3,5,6 Not all the mercury is desorbed during the first reading of the flash heating step. A significant amount of mercury is detected during the second and often the third Jerome readings of a single thermal flash vaporization of a mercurycontaining sample tube.…”

A field screening method for the determination of elemental mercury in environmental soil samples involves the thermal desorption of the mercury from the sample onto gold and then the thermal desorption from the gold to a goldfilm mercury vapor analyzer. This field screening method contains a large number of conditions that could be optimized for the various types of soils encountered. In this study, the conditions were optimized for the determination *To whom correspondence should be addressed. 1665This document is a U.S. government work and is not subject to copyright in the United States. EASTERLING, HOVANITZ, AND STREETof mercury in silty clay materials, and the results were comparable to the coldvapor atomic absorption spectrophotometric method of determination. This paper discusses the benefits and disadvantages of employing the field screening method and provides the sequence of conditions that must be optimized to employ this method of determination on other soil types.

“…The inorganic mercury content was determined by reduction with SnCl2 alone as the release of organic mercury (from methylmercury) was slow. Anderson, Evans, Murphy, and White (5) burnt the sample in a stream of air and collected the mercury in a gold-impregnated fritted glass disk and the mercury was determined by placing the disk in a portable atomic-absorption spectrophotometer.…”

This review follows the previous one (189) and covers the literature and information received by the authors from October 1971 to November 1973. As in the past, it surveys the developments in the determination of the elements in organic materials.Since the commercial CHN analyzers have been on the market for some ten years (186), time is come for an overall evaluation of these automated machines. At the International Symposium on Microtechniques held in University Park, Pa. in August 1973, several practicing microanalysts reported on the performance of the respective apparatus which they had used for long periods. The findings are favorable. At the same time, it is noted that the number of commercial instruments (187, 188) has diminished. Research activities on automation, however, have been vigorous, as evidenced by the papers on coulometric methods, use of ion-selective electrodes, and other elec-
