Re: Vapona or DDVP resins strips

[Sharon Niscak <camscare@xxxxxxxx>]

Hello Elizabeth,

Thank you ever so much and it appears that my thesis seems to be one of the most indepth studies on the effects of DDVP on wool (& textiles & materials).  The only other well publized study was the concurrent study by S. Stephens and Walsh at the Carnegie Museum.

 

I am looking for ancedotal evidence for a request that was forwarded to me by Dr. Kerr and CCI.   Nancy has been extremely helpful and gracious in forwarding the title of another paper that we wrote and slides.

 

Apparently Pest Control applicators are still using DDVP and Vapona resin strips in private collections.  

 

Kindest regards,

Sharon Hammick Niscak

There was a master's thesis done at the University of Alberta (in the 1990's or a bit earlier)about the use of Vapona.  Part of the Collection that it had been used with was very badly damaged- discolored and degradtion of textile artifacts.  This happened because well meaning volunteers didn't know how to use Vapona and there wasn't a conservator with the Collection.

 

I can't remember the name of the thesis but you could contact Dr. Nancy Kerr nancy.kerr@xxxxxxxxxxx  as she was the Master's supervisor.  You could contact her about the thesis.  It would be available on inter-library loan.  Also I think there was a Textile Conservation Newsletter (Canadian) supplement reporting the thesis research.  Nancy can give you the full name of the author. 

 

I'm not in Edmonton or I could do this myself, but I'm sure Nancy will be more than willing to help.  The research was quite interesting. The thesis is quite long and involved so it may be easier to read the condensed version in the TCNewsletter.

Hello All TexConsLers,

Do you know of damage to objects and textiles in the collections in situ from using DDVP (Vapona, SWAT etc) resin strips or dichlorvos for fumigation? 

 

Thanks Margaret I have the Conserve O Gram and S. Williams and Walsh abstracts from the Carnegie Museum.   

 

With appreciation,

Sharon Niscak

Hi fellow TexConsLers ? The National Park Service Conserve O Gram series (available for free download via: http://www.cr.nps.gov/museum/publications/conserveogram/cons_toc.html)

has one (Number 2/4,  dated 1993) specifically outlining the health hazards for humans as well as collections by dichlorvos.

The Conserve O Gram includes references. And states ?Because of its reactivity with museum objects and health dangers, dichlorvos should only be

used in controlled conditions and only when there is no other acceptable material.?

Hello All,

 Looking for reports and information on damage to objects and materials from fumigation with Dichlorvos,  DDVP resin strips, known by names such as SWAP, No Pest Strips or Vapona.

Any experiences related to the use of DDVP as a fumigant are appreciated.

With appreciation,

Sharon Niscak
