"千萬不要將裝著水的塑料瓶放在冰箱裏冷藏，因為塑料瓶會在此種條件下釋放出二噁英。" I can be sure that here the "二噁英" means dioxin proper, 1,4-dioxin/1,2-dioxin. They are different from 二噁英 (dioxin). "二噁英"(PCDDs and PCDFs) is the product of carbon, oxygen, and chroline at high temperatures(suitable at 400-700°C)under the catalysis of metals such as copper. It is most from waste inceneration (1000°C). The toxicity of Dioxins is totally diffent fro mthe toxicity of 1,4-Dioxin.
