Qualitative and Quantitative Aspects of

This chapter has adopted a broad perspective on data collection and incident analysis methods. Both qualitative and quantitative aspects of data collection have been addressed, and data collection approaches have been described for use with large numbers of relatively low-cost incidents or infrequently occurring major accidents. 

The production of polymers by emulsion polymerization has been important since at least World War II. For example, the production of SBR, polybutadiene, and nitrile rubbers was 1.2 million metric tons in 1986 in the U. S. alone (1). Emulsion copolymers are becoming increasingly important from an industrial viewpoint because their unique mix of properties over homopolymers can open up new market opportunities. A review of the qualitative and quantitative aspects of emulsion polymerization can be found in reviews by Min and Ray (2) and more recently by Penlidis et al. (2), and Gilbert and Napper (A).

The pattern and efficiency of hydrolysis of [Leu5]enkephalin, like that of any peptide, depends to a large extent on its compartmentalization. In other words, the qualitative and quantitative aspects of its degradation vary considerably as a function of species, tissue, and concentration profile. Thus, hydrolysis of [Leu5] enkephalin in rat brain is catalyzed mainly by aminopeptidase, ACE, and neprilysin, in rat lungs by aminopeptidase and ACE, and in rat plasma by aminopeptidase, dipeptidyl peptidase III, and ACE [171][172],... 

An interesting extension of enantioselective chromatography on protein based CSPs in LC has been made15-17 using proteins to show qualitative and quantitative aspects of ligand-biopolymer interactions this includes chiral aspects. 

In Steps 1 through 6 the chemist has evaluated batch QC check results and came to a conclusion on the acceptability of the whole batch. In Step 6 the chemist focuses on individual sample QC checks and on remaining qualitative and quantitative aspects of analysis. The chemist reviews the data for each individual sample in order to evaluate the following issues ... 

Qualitative and quantitative aspects of the Lewis theory of acids and bases, and practical applications of Lewis acids, are discussed in a series of monographs [1,4-6,30-46] and reviews [47-49], The following aspects are taken into account (a) electronic configuration of acceptors (A = M MX are generally metal and boron salts), (b) nature of anions (usually halides), (c) peculiarities of thin structure of donors (B are generally the compounds containing N, P, As, Sb O, S, Se, Te F, Cl, Br, I atoms) their electronic structure, spatial accessibility, and mutual position of donor centers. Moreover, the nature of X, order of binding of A and B in formation of adducts of type AB , nature of solvents, and evaluation of AH or AG of the processes (1.1)—(1.5) [31,48] should also be considered. 

Describe the assumptions and uncertainty factors used for the qualitative and quantitative aspects of the assessment, including the impact of extrapolation from the observed data to environmental exposures. 

The concepts underlying these methods can be extended to permit identification of both individual vapors and the components of vapor mixtures from the sensor response patterns [271]. A useful feature of this extended disjoint principal components regression (EDPCR) method is the integration of the qualitative and quantitative aspects of the sensor responses. Implementation of EDPCR has been demonstrated for arrays of polymer-coated SAW sensors exposed to a range of vapors and vapor mixtures [92a,92c,271]. Accurate identification and quantification of individual vapors and vapor-mixture components was achieved.

The history of atomic emission spectrometry (AES) goes back to Bunsen and Kirchhoff, who reported in 1860 on spectroscopic investigations of the alkali and alkali earth elements with the aid of their spectroscope [1], The elements cesium and rubidium and later on thorium and indium were also discovered on the basis of their atomic emission spectra. From these early beginnings qualitative and quantitative aspects of atomic spectrometry were considered. The occurrence of atomic spectral lines was understood as uniequivocal proof of the presence of these elements in a mixture. Bunsen and Kirchhoff in addition, however, also estimated the amounts of sodium that had to be brought into the flame to give a detectable line emission and therewith gave the basis for quantitative analyses and trace determinations with atomic spectrometry.

Organic compounds can generate the initiators of free radical sequences through the primary photochemical processes homolytic dissociation into radicals, hydrogen-atom abstraction, photoionization, and electron transfer reactions. The homolytic dissociation reactions are limited to compounds containing relatively weak bonds (<98 kcal), such as sulfides, peroxides, and some halides and ethers. Representatives of all of these classes of compounds are certainly present in seawater, but the limited information on the qualitative and quantitative aspects of their occurrence does not allow for an estimate of their importance in the promotion of free radical reactions. The same is true for electron transfer reactions, which may be an important photochemical process for organic transition metal complexes.
