Environmental consideration reference information

The foUowing references are useful for information on environmental considerations and recycling. PVC s Environmental Profile Fallay vs. Fact, The Vinyl Institute, a Division of The Society of the Plastics Industry, Inc., Mordstown, N.J., July 1995. 

To demonstrate the preselection procedure that is based on the aforementioned selection guides, two examples will be presented in Tables 11.2 and 11.3. The evaluations are based on the rankings in Fig. 11.6, and for the elaboration of these examples, the numbers reflecting certain important factors are taken without any adjustment to particular conditions of the two projects. As mentioned before, additional factors could be defined and ranked which take into consideration the special projects and, based on published information or experience, the numbers, indicating responses of different agglomeration methods to these factors, could be modified. Contrary to what has been done in the following, referring to Tab. 11.1, in most cases, the influences of site, supply, and environmental conditions as well as infrastructure considerations should be included. 

For the most part, studies in classical solution photochemistry have been conducted under conditions where experimental variables are limited to as few as possible in order to obtain the most unambiguous information from the experiment. Operationally, the experimentalist sets the conditions which are best suited to the particular problem. This approach certainly has its place in marine photochemistry when one attempts to elucidate a particular process, but caution must be used in extrapolating the results of studies where considerable deviation from prevailing natural conditions have heen employed. Extensive liberties have been taken with regard to this point, with the result that the literature now contains many references which were done under the guise of environmental photochemistry, which probably have little or no relevance with regard to the natural environment. It is probably not of value to belabor this point further instead some aspects of seawater which make it a unique photochemical reaction medium will be considered. 

The foUowing examples are provided to iUustrate some of the considerations, not to exhaustively explore this compHcated issue. A model of the whole body is typically needed even for a relatively local stimulus, especiaUy when the heat input represents a significant fraction of the whole body heat load. The reader is referred to extensive handbook entries on environmental response for more information [43,44]. Whole body models of the thermoregulatory system are discussed in Wissler [45].
