Ethylene Oxide Residues in Fumigated Books - a First Result of the Project Men and Books

: EU grant 2012-0920/001-001

Patricia Engel & Katja Sterflinger

In every archive/library in Europe we find - microorganisms - acidic paper - ink corrosion - vegetabil tanned leather Horn I conference 2011 confirmed the need for research in these subjects and defined even more urgent research subjects

Mould on paper, leather, siels, etc.

Reasons

 

New infestation

  

Environment not clean enough Environment too wet Environment too warm



Microclimate Old infestation

Recommendation for the museum/library/archive

    

Good, i.e. individual house keeping policy Stop sorce: Renovation of building / wet areas etc.

Cleaning of books by conservators or staff advised by conservators (health and safety measures!) Repacking Regular control in future climate monitoring etc.

Active measures

   

Dry cleaning (HEPA Filter) Alcohol Gamma rays

 Energy

Ethylene oxide

   But ethylene oxide treatment of paper is

not allowed anymore in the EU

since 1st September 2006.

from 1st September 2013 on EO may only be used according to Article 56 of the BPR (

research and development

) If the use of EO as book fumigant on a regular basis is intended, ethylene oxide has to be included in. Annex I of the BPD and authorised as biocidal product first .

I Questions in this project



Does EO stay in the books, if so how long?



Does off fuming dose pose a risk in readers?



Did EO kill the mold?



Did EO damage the material?

   April – Aug. 1994 346,2 meter in total (261,2 m, 85 m in foulders, 13m notes) The following measures were taken:  1. sources of damage were analysed,     The books were stored in wet/very humid conditions The books were dusty, there are spores in the dust, a risk for human health 10 years ago (1984) the books were brought to dry rooms, but due to tight packing they dryed slowly Humidiy and temperature were measured in 50 books in Junly 1994, the rH was between 59 and 71 and the Temp. Between 19,5 and 23,4^C    The humidity of the air in the room was between 57-62 % and the temperatureat 22,6 Centigrades 2. 9 books and 15 groups of archival documents were selected according to various criteria (sort of damage, ,aterial composition, content) and model restoration was made, 3. Microorganisms were analysed by microscopic observation directly on the books or in complicated cases on growth medium. The following species were found: Streptomyces, Geotrichum, Chaetomium, Acremoniella, Stachybotrys, Epicoccum, Stemphylium, Botrytis. Streptomyces and Geotrichum were found more often.

     4. the entire collection plus the 9 books and 15 groups of archival material was packed and prepared for desinfection  Chamber for 20 m3, 10 kg Petrox, 5 days fumigation, then airwashing until EO detector did not show EO any more  The rooms were desinfected with 2% Aseptin M solution and treatment repeated after 10 days 5. Fumigation with 90% EO and 10% CO2 (Petrox gas) 6. books were air washed and climatized,  In Swidnica 7. dust and microorganism spores were removed from the books in Sept. 1994 (after the report was written) 8. the effectivity of the desinfection was evaluated (report Nov. 1994)

15 years later

 2009 in Ossolineum alle alten Drucke (Signaturgruppe SD) und Handschriften (Signaturgruppe R) begast worden.

 „2010 durch Adam Wilga, der eine solche Begasungskammer erfunden hat, die übrigen Bücher begast (Signaturen 1,2,8000 ).“  „Wenn es um die Signaturen geht, nach denen Sie gefragt haben, handelt es sich um fortlaufende Signaturen (gemäß Katalog Dr. Górski).“  Waiting for data from Ossolineum

MEN AND BOOKS - 2012 For the selection of books several parameters were relevant:

(1) moment of fumigation (17 fumigated in 2009, 11 fumigated in 2010) (2) material composition (11 printed books, 7 ms iron gall ink, 10 modern dye ink, 15 leather involved, 3 parchment involved, 11 textile involved, all book blocks paper of their time) (3) age of the book (2 18 th cent., 12 from 19 th cent. Rest 20 th (4) size of book (folio to octav) cent.) The books for ethylene oxide measurement were chosen aiming to get a representative average of all these features. This is especially important when it comes to transfer data into

application Europe-wide

and on an “average archive” at the end of the project.

28 volumes bound in leather, parchment, paper and textiles, dating from the 18 th , 19 th and 20 th century

, thus representing also different sorts of paper as book block, ranging from folio to quart were selected by the Parish in Swidnica and brought to the European Research Centre for Book and Paper Conservation-Restoration in Horn. There these books were put into a chamber of inert synthetic material of 1 qm volume and stored under closed conditions for 60 days at 20 ° C and 50%rel. H.

Books brought to Horn off gasing measured

Two different analysis methods were chosen to detect the off gassing ethylene oxide

, a

digital handheld device, Dräger X-am 5000

, which turned out to be too rough (measuring range 0 - 200 ppm, resolution 0.5 ppm, smallest possible detection 1 ppm; expected concentration below) and a

GC/FID

. For the later the measurement was passive with ORSA-tubes filled with activated carbon. The measurement lasted for 336 hours. Then the tubes were taken out, closed and sent to gas chromatography. The analysis was made with GC/FID with retention time catalogues and quantification via external calibration function. This standard working instruction is a modified NIOSH 1612. Working conditions: Gaschromatograph “Doppelsäulengerät Sichromat 1-4”; Injektion: split/splitless; 2.5µL splitted auf 2 wide-bore colums, 250 ° C, Colums: 30 m OPTIMA-WAX; 0.53 mm * 1.0 µm and 30 m OPTIMA 1; 0.53 mm *1.0 µm, Both detectors FID (250 ° C), Carrier gas Nitrogen: 2.5 mL/min, burning gas synth. air: 300 mL/min, Hydrogen: 25 mL/min, stove temperature 45 ° C isotherm 10 min, 45 ° C to 180 ° C in 5 ° C/min; 180 ° C isotherm 13 min, 180 ° C to 200 ° C in 10 ° C/min, 200 ° C isotherm 13 min.

The method is based on the international method NIOSH 1612 ( http://www.cdc.gov/n iosh/docs/2003-154/pdfs/1612.pdf

About Material

I suggest to add several book blocks to the fumigation of dummies, as to have more substance to catch the EO gas possibly and get more realistic and controlled measurement for our conclusions.
