Environmental studies

A few studies to monitor our environment with ESR are included in this section. The ESR dating of marine terraces using shells and corals determined the age of the high sea levels and the tectonic uplift of islands.1 The variation of S03 indicated global environmental effect of volcanic eruption.1 ESR spectra of frozen rains, snow and frost as well as ground and river water indicated some 

The origin of Aeolian dust from Chinese desert to Japanese islands was studied with ESR of dust, mostly fine grains of quartz.132 Suspended particulate matter (SPM) collected by environmental protection agency was measured with ESR.133 Dust soot of automobiles was also measured to check the motor combustion rate. Adsorption of NO, Mn2+ and Gd3 on clay minerals, bentonite and se-piolite134 has been studied using paramagnetic ions as tracers for radioactive elements. And studies have been carried out on how divalent and trivalent cations diffuse and blocked by surrounding clay minerals, in the context of their leak from nuclear waste repository to the environment.135

Chromatography is a technique for separating and quantifying the constituents of a mixture. Separation techniques are essential for the characterization of the mixtures that result from most chemical processes. Chromatographic analysis is used in many areas of science and engineering in environmental studies, in the analysis of art objects, in industrial quahty control (qv), in analysis of biological materials, and in forensics (see Biopolymers, analytical TECHNIQUES FiNE ART EXAMINATION AND CONSERVATION FoRENSic CHEMISTRY). Most chemical laboratories employ one or more chromatographs for routine analysis (1).

Element-selective detectors. Many samples, e.g. those originating from environmental studies, contain so many constituent compounds that the gas chromatogram obtained is a complex array of peaks. For the analytical chemist, who may be interested in only a few of the compounds present, the replacement of the essentially non-selective type of detector (i.e. thermal conductivity, flame ionisation, etc.) by a system which responds selectively to some property of certain of the eluted species may overcome this problem. 

One very important group of infrared instruments consists of spectrometers used for quantitative measurements either as part of a continuous industrial monitoring process or for environmental studies. These instruments are normally purpose-made, dedicated machines designed to run virtually automatically, and are normally intended only to measure a single compound or family of compounds. 

The nature of electrochemical instruments makes them very attractive for decentralized testing. For example, compact, battery-operated voltammetric analyzers, developed for on-site measurements of metals (9,10), readily address the growing needs for field-based environmental studies. Similarly, portable (hand-held) instruments are being designed for decentralized clinical testing (11). 

The electrical conductivity detector is probably the second most commonly used in LC. By its nature, it can only detect those substances that ionize and, consequently, is used frequently in the analysis of inorganic acids, bases and salts. It has also found particular use in the detection of those ionic materials that are frequently required in environmental studies and in biotechnology applications. The detection system is the simplest of all the detectors and consists only of two electrodes situated in a suitable detector cell. An example of an electrical conductivity detector sensing cell is shown in figure 13. 

A system is a convenient concept that is used to describe how the individual parts of anything (a system) are perceived to interact. System concepts are used by many disciplines and may form a common framework to support global environmental studies. A system definition must start with the identification of the boundaries of the system of interest. Next, the inputs and outputs to that system must be identified. The inputs and outputs of subsystems are the conventional linkages to other subsystems and facilitate the integration of any part of the system into the whole. As discussed previously, it is important that a common and consistent set of units be selected to describe these inputs and outputs. Once the inputs and outputs... 

The global system studies described by NASA (4) were presented to illustrate the variation in inputs and outputs, temporal and spatial scales, processes, and boundary interfaces associated with different aspects of global environmental studies. The reader should attempt to define these same characteristics for each paper in this volume. I will try to suggest important connections that may be of interest in these papers. How do each of these papers contribute to the understanding of global environmental chemistry What piece of the overall puzzle is provided by each of these papers Can the finding of each paper be tailored to form a piece in a different puzzle ...

Identity. There is considerable variation in the use of terms like, "environmentalist," "environmental sdence program," "environmental studies program," etc., such that no particular background is guaranteed by the use of these terms.
