  11. 11. Results to Date<br />Low variation found in a wide range of repositories => Aldehydes may be removed faster by oxidation or surface removal than by forced removal<br />Acetic acid the most abundant pollutant inside archival boxes, and the one which has the greatest degrading effect<br />Personnel exposure levels below even the most stringent health and safety limits<br />Introduction<br />Experimental<br />Investigations<br />Case Study<br />Conclusions<br />
  12. 12. Future Work<br />Investigate the effect the pollutants have on archival material<br />Investigate the interaction of pollutant concentration, RH and temperature together and with archival material<br />Possibility of a Review of Environmental Guidelines<br />Introduction<br />Experimental<br />Investigations<br />Case Study<br />Conclusions<br />
