The emissions of burning pipes were analyzed by both infrared spectrometry and gas chromatography-mass spectrometry (GC-MS). The emission test results indicate the presence of chlorinated components including chlorine dioxide, methyl chloride, methylene chloride, allyl chloride, vinyl chloride, ethyl chloride, 1-chlorobutane, tetrachloroethylene, chlorobenzene, and hydrogen chloride were detected in the emissions of burning PVC pipes. Furthermore, the concentrations of benzene, 1,3-butadiene, methyl methacrylate, carbon monoxide, acrolein, and formaldehyde were found at levels capable of affecting human health adversely. The analysis of PVC pipe leachates using GC-MS shows that there are 40\u201360 tentatively identified compounds, mostly long-chain hydrocarbons such as tetradecane, hexadecane, octadecane, and docosane, were released when the burned PVC materials were soaked in deionized water for one week. Quantitative analysis shows that 2-butoxyethanol, 2-ethyl-1-hexanol, and diethyl phthalate were found in the burned PVC polymer at the average levels of 2.7, 14.0, and 3.1 micrograms per gram (\u03bcg\/g) of pipe material. This study has significant implications for understanding the benzene contamination of drinking water in the aftermath of wildfires that burned polymer pipes in California.<\/jats:p>","DOI":"10.3390\/toxics7040057","type":"journal-article","created":{"date-parts":[[2019,11,12]],"date-time":"2019-11-12T04:07:07Z","timestamp":1573531627000},"page":"57","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Releases of Fire-Derived Contaminants from Polymer Pipes Made of Polyvinyl Chloride"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7845-6492","authenticated-orcid":false,"given":"Ngee Sing","family":"Chong","sequence":"first","affiliation":[{"name":"Department of Chemistry, Middle Tennessee State University, Murfreesboro, TN 37132, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saidi","family":"Abdulramoni","sequence":"additional","affiliation":[{"name":"Dow Chemical, Indianapolis, IN 46268, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dwight","family":"Patterson","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Middle Tennessee State University, Murfreesboro, TN 37132, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heather","family":"Brown","sequence":"additional","affiliation":[{"name":"School of Concrete and Industry Management, Middle Tennessee State University, Murfreesboro, TN 37132, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"701","DOI":"10.1016\/j.proenv.2016.07.069","article-title":"Toxic Pollutants from Plastic Waste\u2014A Review","volume":"35","author":"Verma","year":"2016","journal-title":"Procedia Environ.
