“…A number of experimental methods exist in spectroscopic practice whereby differentiation of signal amplitude with respect to wavelength may be obtained (5,6). These may be classified into three broad categories, namely, digital storage of the zero-order spectrum followed by computation of the nth order derivative, analogue differentiation of the spectrum, and techniques which employ some form of wavelength modulation to produce differential spectra directly.…”

“…Since the early reports of successful inductively coupled plasma (ICP) analysis (1,2) the technique has rapidly become established as a trace analysis tool in the geological, metallurgical, agricultural, biological, and environmental sciences. The basic work on parametric optimization and instruments development has been thoroughly reviewed (3)(4)(5)(6)(7)(8) as have the available applications data (9)(10)(11)(12)(13). It is clear that the ICP offers benefits over other methods for trace analysis of various metals in environmental and biological samples.…”

“…Recent development of the technique has been reviewed (10). The advantages as well as the limitations of this method have been the topic of several reports (11,12). One of the goals of this study was to evaluate the capabilities as well as the limitations of the SL method practically and realistically by analyzing a complex environmental sample.…”

A technique for Inductively coupled plasma (ICP) sample introduction Is presented by which certain metals are converted to volatile /3-dlketonales and the resulting metal-chelate vapor Is carried by argon Into a stabilized Inductively coupled argon plasma. The feasibility of directly reacting /3-diketone ligands and certain metals with minimal sample preparation Is discussed with qualitative data supporting the direct chelation reaction of Fe, Zn, Co, Mn, and Cr In various matrices (l.e., pure metal, National Bureau of Standards (NBS) bovine liver, human blood serum). Quantitative data for the determinations of Fe, Zn, and Cr In bovine liver and In blood serum are presented and compared with values obtained by alternative analytical methods. Advantages and limitations of this technique over existing means of ICP sample introduction are discussed.

We encountered three patients with chronic interstitial pneumonia with many bullae in the lower lung fields whose lifetime occupation was teaching school. Pathological examination of autopsy lungs of these patients revealed interstitial pneumonia and multiple bullae throughout the lungs, including the lower lobe. Since blackboard chalk has been used as a popular writing material among teachers in Japan, the mineral contents in the lungs of two of the three cases and four control cases with idiopathic interstitial pneumonia (IIP) (whose occupations were not teaching) were analyzed. The amount of deposition of total dust, inorganic dust, non-SiO2 inorganic dust, and calcium was significantly higher in the lungs of two schoolteachers compared with those of the control lungs. The amount of free silica in case 1 and alpha-quartz in case 3 were also significantly higher than in the controls. Two thirds of the chalk produced in Japan is still made from gypsum and involves small amounts of silica and other minerals, in addition to calcium. These findings indicated the deposition of chalk in the lungs of these patients with interstitial pneumonia and multiple bullae.
