Releases of Fire-Derived Contaminants from Water Pipes Made of Polyvinyl Chloride Polymer

Abstract: In order to assess the human exposure risks from the release of contaminants from water pipes made of polyvinyl chloride (PVC), experiments were carried out by subjecting the PVC pipe material to burning and leaching conditions followed by analysis of the emission and leachate samples. The emissions of burning pipes were analyzed by both
