The article discusses the persistent challenges in managing biodeterioration in Portuguese institutions, particularly in archives and libraries. Despite historic efforts towards preventive conservation, the use of chemical products for pest control remained prevalent until the late 20th century.
Concerns over human health and environmental impact led to the discontinuation of harmful fumigation gases like methyl bromide. Challenges such as pest infestations by termites and silverfish underscore the necessity for effective preservation strategies. Oxygen displacement and nitrogen treatment are recognized methods for eradicating pests in cultural heritage objects.
The focus on preventive conservation and raising awareness among archivists and librarians is crucial for the long-term preservation of graphic cultural heritage. The article provides a historic review of different methodologies used to prevent biodeterioration in the Portuguese context and compares them to international trends. It then highlights the need for a shift towards sustainable management practices and increased collaboration between research groups and heritage institutions. It also emphasises the importance of detecting contamination levels, assessing health risks, and developing mitigation methodologies.
The lack of awareness among decision-makers regarding the harmful effects of past chemical product use poses a significant challenge. Overall, the article stresses the urgency of addressing these issues to ensure the preservation of cultural heritage for future generations.
