• Description:
  Objective: The purpose of this research was to attempt to determine the effects of fungal growth on the phthalate ester constituents of the plasticized PVC (pPVC) film component of metal building insulation used in a large book warehouse. We also investigated the potential exposure implications on the workers in the building. Methods: Individual 232 cm2 pieces of the pPVC film that were clear of fungal growth and pieces that had fungal growth were collected from the building being investigated. A chemical analysis of the phthalate ester content was then performed on the pieces by solvent extraction followed by analysis of the extract using a GC/MS technique. The mass of phthalate ester content in a sample set of 25 pieces each of the clean pPVC film and pPVC film with fungal growth collected was statistically compared. The results of the chemical analysis were then used to model the potential increased exposure the fungal growth may contribute to the occupants of the building by determining a worst case exposure scenario and comparing that to published exposure data in similar settings. Results: The results of the chemical analysis showed that there is a statistically significant difference between the clean pPVC film and pPVC film with fungal growth for all four phthalate esters investigated. The results also showed that the mean content of all four phthalate esters was lower in the pieces that had fungal growth. The mean content will be used for exposure assessment modeling purposes, which is still being investigated. Conclusion: The presence of fungal growth is related to lower phthalate content in the pPVC film. Our plan for future investigation of this problem is to use the collected data for exposure assessment modeling. [Description provided by NIOSH]
