“…Coated piezo-electric quartz crystals ( pqc) have also been investigated as an alternative method of measurement of damage to specific materials from volatiles and other environmental factors (Odlyha et al, 2011). It has been observed that A-D (acid-detector) strips give a useful and quick visual guide to expected levels of volatile acids (Fenn, 1995;Hacke et al, 2014).…”

Acid-detector (A-D) strips were originally developed to assess the deterioration of acetate film stock, but they can also be used more generally within enclosures to detect volatile acidic pollution. A hand-held reflectance spectrophotometer was used to record the colour of individual strips in order to make consistent and reproducible readings. Calibration was carried out using the yellow-blue axis b*(D65) value in the CIELAB1976 system to measure the colour of A-D strips suspended in enclosed containers over solutions of acetic acid in combinations with glycerol to control the relative humidity (RH). A-D strips were found to be sensitive to changes in high RH (60-90%) but affected little by changes in lower RH or temperatures in the museum display and storage range. A-D strips can be used to establish the presence of volatile acids, record the indication of acid vapour concentration, explore conditions within a container, and to find sources of volatile acidity. They respond very quickly and several can be placed around an object. They therefore show promise for measuring slowly changing conditions, such as seasonal changes and the gradual accumulation of acidity in poorly ventilated containers and spaces. A-D strips proved useful in assessing air quality in storage and display enclosures. Examples and test results are presented. Wellsealed plywood transit frames and storage cases were found to be most polluted with volatile acids. Storage rooms with air filtration systems but filled with wooden objects had significantly reduced air quality.

“…The cardboard and rubber elements are particularly oxygen-sensitive, and tend to delaminate, crumble, crack, and discolor. Special energy and material intensive storage conditions will retard decomposition (Dyer et al, 2011;Hacke et al, 2014;Shashoua, 1999). Photograph courtesy of the Robert Rauschenberg Foundation.…”

“…Cultural heritage and historic collections frequently contain objects that require insect eradication or long-term storage under anoxic (low oxygen) conditions. Optimal anoxic treatments involve placing the object(s) in sealed, oxygen-impermeable enclosures, reducing the oxygen content to less than 1%, and maintaining the anoxic environment for a given period (Hacke et al, 2014;Shashoua, 1999;Trafford & Allington-Jones, 2017) establish an anoxic environment, preservationists decrease the oxygen concentration within an enclosure (constructed from plastic sheets and PVC tubing) by purging it with nitrogen or argon gas or by adding a scavenging agent that binds with oxygen such as zero-valent iron, which is the main component of the commercial oxygen scavenger Ageless ® . To account for potential enclosure leakage, the anoxic environment is maintained with a flow of the purging gas as needed, or with sufficient oxygen scavenger (Shashoua, 1999).…”

Modeling environmental impacts with care professionals & examining hazardous air pollutants in environmental justice communities in Massachusetts

The climate crisis is one of the primary challenges facing society in the 21st century.Environmental emissions and burdens need to be identified and quantified before they can be effectively reduced or eliminated. One available environmental impact modeling tool is life cycle assessment (LCA). The research in this dissertation builds upon the existing codified LCA framework to improve outcomes for stakeholders by directly including them throughout the entirety of the LCA process.Three case studies in this dissertation implement a collaborative, co-creation research approach through partnerships between LCA researchers and stakeholders in care-oriented fields, specifically cultural heritage and healthcare. LCA provides decision support by comparing the environmental impacts of functionally equivalent alternatives, however, results from standard LCAs can be difficult for stakeholders to use to implement change because the scenarios are not broadly representative or inclusive. Under this collaborative methodology, the majority of project time was invested in co-developing the scenarios and alternatives to address this gap.The final research chapter in this dissertation is also orientated around communities but geographical rather than professional. Historically in the United States, communities across racial and class strata, have not equally nor equitably experienced environmental exposures and harms.Environmental justice (EJ) is an interdisciplinary field, body of research, and social movement working to identify and address inequities and injustices in our built environment. This chapter examines hazardous air pollutants (HAPs) through the lens of Massachusetts-specific EJ designations. Statistical and spatial analyses showed differences in HAP distribution, and proximity to HAP stationary sources that are not fully explained by EJ. In addition to current demographic-iii based EJ designations and policies, there is a need for additional EJ criteria that quantify environmental burdens and benefits to adequately capture and better address inequalities in HAP exposures throughout the state.Environmental assessment tools provide critical information to communities for them to understand current environmental health risks and guide more sustainable actions in the future, but they must be applied in an inclusive manner. The highly collaborative, co-creation approach employed in this dissertation ensures that the research is relevant and broadly applicable to a range of community stakeholders.the Humanities (PR-268771-20). I would also like to express my deepest appreciation to Dr. Jodi Sherman, Sarah Nunberg, Sarah Sutton, and the many cultural heritage professionals and graduate students for allowing me the privilege of working in partnership with them on this research. Special thanks to Dr. Jerry Hajjar and the Civil & Environmental Engineering faculty and staff for all of their support and for fostering such a close-knit community. I would also like to extend my gratitude to Asst. Dean Rachelle Reisberg and Assoc. D...
