Occurrence, Production, and Uses

General information regarding occurrence, production and use, and physical-chemical data (table for physical-chemical data)... 

Lithium, the not so rare metal , is reviewed. The discussion covers the occurrence, production, and uses of the metal and its compounds. The metal has considerable potential in the future generation of electrical energy from the fusion reaction ... 

This report is based on recent documents by Brisman (1994) and Kanerva and Brisman (i997) It is focused on immunologically mediated adverse effects of enzymes on the skin. General aspects of enzymes, such as occurrence, production and use, are included.

Exposure data and other information on an agent under consideration are also reviewed. In the sections on chemical and physical properties, on analysis, on production and use and on occurrence, published and unpublished sources of information may be considered. 

The preceding examples and the treatment of the metallurgy of iron are typical of the processes involved in the production of metals of relatively high density. The remaining heavy metals that are used industrially are not considered in detail here. However, Table 11.8 gives a limited selection of information on the mode of occurrence, metallurgy, and uses of these metals. 

More information on the chemical and physical properties of 1,1-dichloroethane can be found in Chapter 3, on its production and uses in Chapter 4, and on its occurrence and fate in the environment in Chapter 5. 

Some of these polycyclic musk fragrances were also found in humans [358-360]. Consumption of fish and other food from aquatic ecosystems contaminated with PMFs can not explain the concentration in human. It is assumed that the occurrence of these lipophilic compounds in human adipose tissue or mother s milk is mainly due to dermal sorption from cosmetics and detergents [349-351]. In the future the production and use of polycyclic musk fragrances will still increase and the nitro musk compounds will be replaced by the PMFs.

In this chapter the chemical and physical properties, production and use, analytical methods, environmental fate and occurrence and the toxicology of PBBs and PBDEs, are discussed. 

This book provides an introduction to the nature and occurrence, properties and uses, and formation and breaking of foams in the petroleum industry. It is aimed at scientists and engineers who may encounter foams or apply foams, whether in process design, petroleum production, or research and development. Primarily the focus is on the introduction and subsequent application of foam principles, and includes attention to practical foam problems. Books available up to now are either principally theoretical (such as the colloid chemistry texts) or focus on foams in general (like Bikerman s classic books). A significant gap in this coverage concerns foams in the petroleum industry, a topic that is not only of great practical importance but also presents many problems of fundamental interest.
