ChatGPT的回答来了, 哈哈 No, it is not fair to say that the combustion of liquid chloroethene in the open air will not form dioxin solely based on the fact that chloroethene is a monomer with fewer carbon atoms than dioxins. The formation of dioxins is a complex process that involves the interaction of multiple factors, including the presence of other chemicals, the temperature, and the duration of the combustion process. Incomplete combustion, where there is a lack of oxygen or the temperature is not high enough, can lead to the formation of various byproducts, including dioxins, even from compounds with fewer carbon atoms. Therefore, a more detailed analysis of the combustion process and the potential for dioxin formation would be needed to make a definitive statement about its safety. Benzene can be formed via the combustion of linear molecule like ethylene, although the conditions required for its formation are generally not those typically found in standard combustion processes. Under normal combustion conditions, the reaction of ethylene with oxygen typically produces carbon dioxide and water. However, if the combustion conditions are such that the temperature is very high and the oxygen concentration is very low, then it is possible for some of the ethylene to undergo pyrolysis, which can lead to the formation of benzene and other aromatic compounds. This process is known as thermal cracking, and it is typically used to produce benzene and other aromatic compounds from crude oil or other hydrocarbons. Therefore, while it is possible for benzene to be formed via the combustion of ethylene, the conditions required for its formation are not typically found in most combustion processes.

EPA lists additional chemicals released in East Palestine train derailment https://www.wesa.fm/environment-energy/2023-02-13/epa-lists-additional-chemicals-released-in-east-palestine-train-derailment The Environmental Protection Agency sent a letter to the railroad company, Norfolk Southern, Friday, documenting contaminants that could have been released into the environment, including three that had not previously been reported. The agency also notified the company that it is potentially liable for the cleanup costs under the federal Superfund program. Of the roughly 50 train cars that derailed on Friday, Feb. 3, about 20 were listed as carrying hazardous materials. On its website, EPA posted a list, provided by Norfolk Southern, of the chemicals in the cars involved in the derailment. Two chemicals, butyl acrylate and vinyl chloride, have previously been disclosed, with vinyl chloride leading to a mandatory evacuation last Monday. In its letter to the company, EPA listed the three other chemicals involved in the derailment: ethylhexyl acrylate, which can cause burning on the skin and in the eyes, coughing and shortness of breath; isobutylene, which can make people dizzy and drowsy; and ethylene glycol monobutyl ether which can cause coughing, dizziness, drowsiness, headaches, nausea, and weakness if inhaled. EPA stated that “materials released during the incident were observed and detected in samples from Sulphur Run, Leslie Run, Bull Creek, North Fork Little Beaver Creek, Little Beaver Creek, and the Ohio River.” The letter also stated that materials were observed entering storm drains.
回复 264楼helloterran3的帖子 你别逗了好吗， 你把如此先进的处理法规发出来供我们学习一下好吗。 中国这些专业机构大概还是比你靠谱点。知道倒土里大部分也会挥发掉。 再给你引用一段， 这种化工原料的降解机制不知道研究多少年了, Sediment and Soil. Most vinyl chloride present on soil surfaces will volatilize to the atmosphere. Vinyl chloride is also mobile in soil and susceptible to leaching (Lyman et al. 1982). Because vinyl chloride is soluble in organic solvents (Cowfer and Gorensek 2006), the presence of other organic solvents, such as those found at hazardous waste sites, may affect the mobility of the substance in the soil. Photodegradation on the surface of soils is possible since sensitized photodegradation in water occurs; however, this is not expected to be an important environmental fate process for vinyl chloride in most soils and sediment
有机化学其实是最微妙的, 你引用的都是论文, 论文和真正的化工反应还差的很远. 二恶英主要的不是氯而是苯环(benzene, 就是那个dibenzodioxins中的benz, 化学命名中会缩写) , 对于直链碳有机物来说是没有苯环的, 合成不出来二恶英.
厉害，mark

已经有不适了，还问啥？ 赶紧离开啊。如果能wfh，就去外州找个地方住一两个月。到时候污染的情况会更清楚。至少空气中的污染物也会基本消散。
这怎么是人类作？只是一些不把人命当命的人在作吧。前面有人说政府不可能故意隐瞒消息的否则被告死，但现实中很多人不是一下子生病啊，东北部其它地区，如如果几年后居民开始生病，或者有人搬走了才开始生病去，律师才开始告，取证诉讼又花几年，那这十年八年的，大家怎么办？真的是，很好笑啊，唉。
环境的AP好多在研究这个的。PFAS溶于水且不容易被现有自来水处理工艺去除，所以是个大问题。二恶英不溶于水，从国内水厂发表的文章看，国内的自来水处理工艺已经能处理掉二恶英。再加上华人家庭经常装净水系统出水是纯净水。 很多年前东北有一次大规模有毒有机物泄漏与河流中，大家很恐慌，清华水处理的教授去了说 投放大量活性炭 解决了有毒物质进入饮用水。pfas这种溶于水的有机物在饮用水处理要难得多。

这种老的实验室论文，做的是封闭反应体系的单体燃烧，就这样dioxin都产生的很少。 这次是把泄漏出来的氯乙烯在户外燃烧 和封闭体系的不完全燃烧没有可比性。 其实这次主要就是盐酸了，2，300吨的盐酸进入当地水域和土壤，以后需要大力的治理恢复。 农产品也没啥好担心的，土壤酸度没调过来前，哪里长得出来。。。

这才是正确的解读
化工不是化学系。化工系的三传一反，对化学反应的理解都是基于反应器特定条件下简化的简化。而现实生活中，氯乙烯的不完全燃烧会产生众多化合物。而其中，很多毒性都很大。
这件事，一不能草率说没事，也不要觉得天真的塌下来了。还是要科学的对待，理性的应对
我化学本硕，化工博士。当然也只略懂化学和化工，疫情疫苗经济政治军事那是都没啥懂的。 By the way, 这次处理是把泄漏出来的引出来在自然空间燃烧，不是密闭的垃圾反应炉那种烧法。
唉 我觉得美帝大概率不会认真修复了 反正地方大人少
so...
就事论事，氯乙烯爆炸泄露后的影响，是个复杂的连锁反应。二恶英是否会出现？科学上说是可能的 二恶英是不是主要致毒致病物，大概率不是。 但是泄露的危害是确实的，实在的，很大的。
朋友是有机化学博士，他的说法跟你基本一致。不烧的话泄漏毒性更大，且不好清除。烧了主要是盐酸污染，相对好治理一些，也容易监控
泄露了，除非不计成本先富集，不然怎么烧啊？
大概率就是泄露到土壤河流里了。方圆百里（虚词），人畜都应该撤离。
他这个解读要么是选择性或者自己不理解。 就以其中一篇文章为例 https://www.sciencedirect.com/science/article/abs/pii/S0957582000708445
文章的结论是燃烧单体产生活化的active chlorine 会和 含苯化合物反应产生二噁英 。实验中是额外加了了苯环类化合物去反应。 但现在这种情况就是单体燃烧为主，一是 周围能接触的苯环化合物并不会很多， 没有大量的苯环化合物供应，二是开放空间供氧充足， 燃烧产生的温度很高 。 所以二噁英产生不会多， 不会多于直接大量焚烧塑料垃圾和生活垃圾一点不奇怪。
当然， 要是这公司也混着运苯环类物质那就另说。 但这种事估计没有哪个公司会干。
新闻里不是说了吗，引流到坑里然后人为点火烧了。
怎么到美国就突然转性变成切尔诺贝利事件了？焚烧变成毁灭罪证了？ LOL 怎么同样的氯乙烯啊奥密克戎啊到了美国没有正确思想指导就变成了洪水猛兽，到了中国就变成了人畜无害？厉害啊！
你这话几乎等于没说什么 2，300吨盐酸进入当地水土，当然是很大的环境伤害
现在讨论的焦点被转移到‘二恶英’这个比较出名的毒物上了 很多PHD就在纠结二恶英有多少，而忽略了真正的危害是氯乙烯泄露和其不完全燃烧产生的大量有毒物质。
我们不可因为‘二恶英’生成多少而判断这次事件危害的轻重。Just FYI
有没有发现有些人是不看新闻里面处理细节的？ 然后热火朝天的讨论二噁英
能引多少，能烧多少？btw，有机物易挥发
引流燃烧是没有办法的办法。但是要是相信媒体，认为这就是保全之法，那就是个joke了
我同意现在热火朝天讨论二恶英是无意义的转移焦点。
新闻里说五个车厢。现在不是在讨论燃烧这一处理方法对不对吗？
不然你觉得怎么处理更好？
你点赞那个帖子里面两遍文章都是关于二恶英的。 至于其他有害物， 不完全燃烧的产物也早就有研究了， 结论还是主要危害来自产生的盐酸。 你觉得还有啥其他大量的有害物质
不燃烧危害大多了，也更难控制扩散
氯乙烯本身释放到土壤里用紫外线分解反而没那么毒,影响范围也小得
这一烧，各种不完全燃烧的毒气扩散出来，那就没有上限了
但是氯乙烯倒进土壤那就成了固定的证据，以后要被人打官司赔死
点火烧光，虽然总污染增加几百倍，但是气体污染物扩散到全美国全世界，你就很难抓到确切的证据。打个官司还得battle好几年，多半就混过去了
的确如此
容易让人告 VS 不容易让人告
傻子都知道怎么选
至于真实伤害什么的，who the fk care?

为什么把ohio的泄漏说得这么严重 而把张家口的泄漏说得那么轻巧？

专家， 能不能别出来现了 还紫外分解呢， 分解你个毛线，本来就是单体， 又不是聚合体PVC。 你前面还说张家口烧的氯乙烯是气体， 咋现在这么快就忘了？ 都是气体还烧个毛线来销毁证据， 直接倒出来挥发掉不就完了吗?
用脑子想一想，气体和液体密度一样，这符合常识么？
一立方米重达一吨，这是什么神奇的气体？
所以，你的意思是整个火车里都没有铜零件？电线里也不会有？
中国早在2013年就修改了氯乙烯的MSDS文件了，处置方法是物理吸附和紫外照射，用人话说就是能吸附多少吸附多少，剩下的交给太阳。
让阳光完成聚合和脱卤，这是目前为止人类科技水平能做出的最优解，当然当地土壤，空气和水质基本全完蛋了。
要是氯乙烯稳定得很，那一开始就不该点火。但是我记得前面有人给放火洗地的理由恰恰是，氯乙烯在露天本来就容易分解自燃。
不顾自己安危，拼命给恶行洗地。这是什么精神？
你有脸谈脑子， 液化气是加压条件下才能以液体存在， 你倒出来还能是液体吗、 要不要去中学玩一下液氮
听说不得不点燃是因为不点燃就要爆炸了。。。
气体氯乙烯密度 0.9106 g/cm3 at 20°C (gas) 液态氯乙烯密度 0.983 g/cm3 at -20°C (liquid) 都是要压缩储存的 所以密度高 液态只不过要冷冻 在冷战状态下存储运输 减少挥发
vinyl chloride density: 0.9106 g/cm3 at 20°C (gas), 0.983 g/cm3 at -20°C (liquid)
1800吨这个是算错了的，用的密度和体积不是一个压强条件。大概是5-10吨。1800吨的话半个河北都没了。
thanks for sharing bless
从罐车里泄漏出来，然后引流到一个沟里面引燃，你还要怎么富集？再装回到罐子里？
你终于说到点子上了，这个事件的关键就是燃烧是否充分。基于目前公开的信息，燃烧应该是充分的。而且，烧氯乙烯和烧聚氯乙烯差别很大。烧聚氯乙烯确实容易燃烧不充分，产生大量二恶英。
你和pastoris两位说的是在行的。泄漏之后燃烧是两害相权取其轻的做法，燃烧这个处置本身是在已知条件下最优的办法。但是泄漏当时可能已经有（相对少量）的逃逸了，燃烧当时产生的其他毒物难以完全预料，也肯定是有毒的只是毒性（相对比较而言的）大小。即使只看颗粒物与污染，也不是可以忽略的（虽然要追踪其后续危害很难），还有看上去似乎都不那么可怕然而实际也不是小问题的盐酸污染。 现在的科技水平不足以完全衡量危害，而机构们比如EPA完全不像一般人想象的那样有权力和有责任。诉讼也完全不像一般人以为的那样有用。 这个问题的源头，是为什么会脱轨会泄漏呢？这个才是问题的开始。
你查查维基资料 vinyl chloride density
那你觉得怎么样处理才是好的呢？指手画脚是容易的，解决问题可不是打嘴炮就行的。
从一开始就不泄漏呀。泄漏肯定就是会产生危害的，燃烧只不过是做能做的。
对的 看看氯乙烯的性质： Flammability: highly flammable and explosive gas; flammability range is 3.6% to 33% (concentration in air)
因为张家口这事儿根本就没有发生过，没有发生过，没有发生过。有不同意见的同志请举手。
IL 水质都被污染了? why?
我认为Athenils和pastoris两位已经很客观了。这个事情上面，韭菜在哪里都是悲惨的和承担污染的。中国和美国，只要这种事情能发生，都是狗屎国。你要argue说美国相对臭得少点，也许吧，这个比衡量污染的后续还难量化。
跟这位专家别太较真， 人天文地理疫苗病毒都涉猎， 之前力证中国封城是最好的抗疫情措施， 可惜中国政府不听他的，直接180度转身，在大冬天选择躺平

在使用石化产品的情况下：认真遵守安全规范，及时检查铁路状况，带有良心考虑普通居民 －如果这些是然并卵，那不是狗屎国是什么，天堂？
只要能完全燃烧，产生的副作用应该是最小的。我搜的很多篇文章，教授，专家的顾虑都是担心其中的不完全燃烧，外行也完全不懂这个引到沟里烧的操作是不是能够保证完全燃烧。能不能share一下你看到的新闻？
这的确是美国做得烂的地方
估计以为伊利诺伊在Ohio 东边
起码转移到空旷无人居住处，但那个成本太高，政府不会为了民众浪费钱
你怎么知道燃烧充分？
你别逗了好吗， 你把如此先进的处理法规发出来供我们学习一下好吗。 中国这些专业机构大概还是比你靠谱点。知道倒土里大部分也会挥发掉。
