Dioxin sources and industrial emissions control — a review

摘要: Dioxin, the collective term for polychlorinated dibenzo‐p‐dioxins and dibenzofurans, are generated during various chemical high temperature processes. They have been shown to be toxic humans animals with 2,3,7,8‐tetrachloro‐dibenzo‐p‐dioxin (TCDD) exhibiting greatest toxicity. Dioxin has exhibit immunotoxicity, reproductive developmental toxicity in several animals. Epidemiological studies on groups of prolonged or elevated exposure dioxin indicated increased cancer rates above threshold levels exposure. Conversely, other concluded that is a net anticarcinogen. There much study aimed at quantifying relative contributions identified sources environmental load. Although some data suggests burning vegetation produces measurable amounts it rather industrial process waste streams which emit amounts. Processes implicated include organic synthesi...
