Industrial hygiene types

Recently, tubes for higher temperature operation containing some common industrial solvents have been introduced. Some of these are listed in Table 4.7. These permit low concentration standards to be prepared for some industrial hygiene-type analyses.

We have seen that the state-of-the-art methods for spraying or immersing the desulfurization slag in water have the potential to cause difficult air emissions and industrial hygiene problems. Several foundry companies and research groups have evaluated three different basic types of reactors for treatment of calcium carbide desulfurization slag. 

Extensive industrial hygiene surveys have been carried out in many countries, and they have provided information on the types... 

Atomic absorption has become the primary method for determining metal concentrations in industrial hygiene samples. The types of samples that can be analyzed in AAS will be discussed along with acid digestion methods and AAS atomization techniques. No attempt will be made to thoroughly review the theory... 

Multielement analysis will become more important in industrial hygiene analysis as the number of elements per sample and the numbers of samples increases. Additional requirements that will push development of atomic absorption techniques and may encourage the use of new techniques are lower detction and sample speciation. Sample speciation will probably require the use of a chromatographic technique coupled to the spectroscopic instrumentation as an elemental detector. This type of instrumental marriage will not be seen in routine analysis. The use of Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) (17), Zeeman-effect atomic absorption spectroscopy (ZAA) (18), and X-ray fluorescence (XRF) (19) will increase in industrial hygiene laboratories because they each offer advantages or detection that AAS does not. 

Aerosol science plays a key role in many different fields including (a) atmospheric sciences and air pollution, (b) Industrial production of pigments, fillers, and specially metal powders, (c) fabrication of optical fibers, (d) industrial hygiene, and (e) contamination control in the microelectronics and pharmaceuticals industries. Aerosols present in such applications can usually he considered as desirable or undesirable, but the same basic concepts apply to both types. Specialist. in the various applied fields increasingly make use of similar theoretical concepts and experimental techniques in solving aerosol problems. These common approaches are the focus of this book.
