ABSTRACT

Evaluation of Diperadipic Acid as a Surface Decontaminant for Spore-Forming Biological Agents   [open pdf - 411KB]

"An environmental contamination incident involving an infectious or contagious biological agent may pose significant risks to human health. Currently, there are a limited number of sporicidal chemicals that are approved for use against 'Bacillus anthracis', the causative agent of anthrax. Characterization of potential decontamination options, ahead of a contamination incident, are important to ensure response and remediation operations initiate promptly and are effective. The current laboratory-scale study was undertaken to evaluate the decontamination efficacy of diperadipic acid, under application conditions that were found to be effective for pH-adjusted bleach (a common sporicidal liquid). The results showed that diperadipic acid demonstrated >6 Log Reduction on glass surfaces, but <2 Log Reduction on concrete. Like studies with pH adjusted bleach, viable spores were found in runoff samples, indicating that relocation of contaminants from surfaces may be possible during decontamination."
