- Abstract:
- ... This review provides a summary of the levels and profiles of PCDD/Fs throughout China, as reported in peer reviewed literatures since 1997. The literature shows that PCDD/Fs are widespread in various environmental media including air, water, sediment, and soil. PCDD/Fs concentrations in air were relatively low in most regions, with only a few areas considered polluted. Many studies reported season ...

- Abstract:
- ... Polychlorinated dibenzo‑p‑dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are highly toxic, carcinogenic and mutagenic to humans. As precursors of PCDD/Fs, dibenzofuran (DF) and dibenzo‑p‑dioxin (DD) have received considerable public and scientific attention. To reduce the emission of PCDD/Fs, it is critical to explore the formation mechanisms of DF and DD. The present study delineated t ...

- Abstract:
- ... Secondary copper smelting production is one of the largest polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) emission sources in the world. However, the formations and emissions of non-2,3,7,8-PCDD/Fs have rarely been studied. Toxicology and metabolism studies have proved that non-2,3,7,8-PCDD/Fs may also be toxic to mammals. To better explore the pathways and mechanisms involved in tr ...

This protocol was carried out under mild reaction condition without any precious catalysts in generally moderate to good yields. Additionally, a plausible mechanism for the transformation was proposed. ...
