I want to put in a word for thermal treatments. Both high and low temperatures, of course, are as effective as anoxia, and many conservators, includin some in charge of large ethnographic and natural science collections, have used one or the other on thousands of objects over many years, with excellent results.
It seems to me that high-tech has a great deal of appeal for a wide range of reasons, not all of them scientific! One, unfortunately, is the lack of access to a substantial amount of research carried out at the Canadian Conservation Institute on both heating and cooling, and including RH studies and conditions required for a complete kill. The RH situation is somewhat counter-intuitive, but has to do with what happens when an object takes up almost all of the volume of a countainer, with relatively little air.
The CCI Technical Bulletin no. 29, available at www.cci-icc.gc.ca/bookstore/index-e.cfm is a good place to start. This includes specifications for using ambient outdoor weather condition for both heating and cooling, as well as the more usual sources. Some of the research, however, was published in obscure conference prodeedings, and not all are in AATA . You can find more references to the work on B-CIN (www.bcin.ca). If it's easier to look under authors, try Tom Strang.
