Mobilization Of The Flame Retardant Antimony Trioxide By Fungal Decomposition Of Fiberglass Ductboard

Abstract:
This research examined the effects of fungal growth on a commonly used fiberglass ductboard insulation that was treated with antimony trioxide flame retardant. We demonstrated that growth of Aspergillus versicolor reduced antimony trioxide levels by 25% to 43% at varying rates over the course of one to 29 weeks. F ...
