Sources and recommended reading

A final note of cantion the toxicity information provided on indi-vidnal chemicals is hy no means complete. Data have been selected to illnstrate certain principles no attempt is made to provide anything close to a thorongh toxicological evaluation of any of the chemicals discussed. The Sources and recommended reading section, appearing after the final chapter, lists several authoritative sources of toxicity information on individual chemicals. 

First, the procedure now used by the EPA for inhalation data differs from what we have described above, in that the ten-fold factor for interspecies extrapolation (animal-to-human) is dropped in favor of a specific model that describes the well-known physiological differences between animals and humans that affect the relative rates of movement of a given administered dose of a chemical in the respiratory tracts of animals and humans. These physiological models provide fairly accurate predictions of the relative doses of chemicals delivered into the respiratory regions of animals and humans who have received identical administered (inhaled) doses. The estimate of delivered dose offers a well-accepted scientific approach to at least part of the problem of interspecies differences. Details of the delivered dose calculations are beyond the scope of this book (see references in Sources and recommended reading). 

See text for discussion of how these PK and PD factors can be used. The Sources and recommended reading section provides citation to the basis of these figures in the work of A. Renwick. 

Desk research consists mainly of reading as much as possible about other people s experiences and recommendations. Read industry publications to find out what is currently in demand and what looks promising for the future, as well as what price ranges are available for various products. If there are one or two people who have published material of particular relevance, then if possible go and speak to them in person. They may say more in person than they will write, or their work may prove to have been derivative, in which case find the original source. Market research reports and trade publications can be obtained from most local libraries. Most broadsheet national and local newspapers report occasionally on the organic food industry, and sometimes it is possible to identify a gap in the market. 

A selection of sources and recommended further reading must include the pro-alternatitive medicine lobby as well as the ant-alternatitive medicine lobby so that the intersted reader can draw an independent conclusion. Note that the prestigious Mayo... 

Heating a flask. Since they are cold-blooded creatures, flasks show more of their unusual behavior while being heated. The behavior is usually unpleasant if certain precautions are not taken. In addition to star cracks, various states of disrepair can occur, leaving you with a benchtop to clean. Both humane and cruel heat treatment of flasks will be covered in (see Chapter 13, Sources of Heat ), which is on the SPCG (Society for the Prevention of Cruelty to Glassware) recommended readings list. 

The encyclopedia is meant to give relatively succinct overviews of sometimes very complex subjects. Formal references and footnotes were dispensed with because these seemed less relevant to the encyclopedia s goals than a simple list of recommended readings designed to lead the reader to more detailed information on a particular subject entry. The entry on Information Resources leads readers to print and electronic sources of information in toxicology. 

The AATCC system is a very detailed dye class identification system. The brief description of some basic tests in this chapter is only for the purpose of introduction. Readers are recommended to obtain thebook Analytical Methods for a Textile Laboratory by the AATCC in order to comprehend the complexity of the dye analysis. Of course the other books and journal articles listed in the references are also excellent information sources. Whenever possible, reading these materials would definitely help develop a better understanding of colour chemistry, which will ultimately ensure that the dye analysis is performed more effectively and efficiently. 

This section gives a brief summary of the most critical aspects of surfaces, interfaces and grain bormdaries. Numerous books have been written on this subject. For a single source on the physics of surfaces the reader is referred to Desjonqueres or Zangwill in the recommended readings.
