3号晚上derail,六号开始烧,那两天东北风,瞄准的是多伦多和五大湖区。。
Neil Donahue, a professor chemistry at Carnegie Mellon University in nearby Pittsburgh, said he worries that the burning could have formed dioxins, which are created from burning chlorinated carbon materials.

而且氯化物烧可以直接产生dioxin,充分燃烧也可以产生dioxin的前驱物。。这玩意就是在大气里飘来飘去的,化学性质稳定。。看现场浓烟,非充分燃烧。。
Dr. Lynn Goldman, dean of George Washington University’s School of Public Health, agrees this is a possible risk, but is more concerned about uncombusted vinyl chloride vapors that could be lurking in the immediate vicinity.-baidu 1point3acres
“Until there has been a thorough assessment, the soot as well as any other materials should in my opinion be treated as contaminated by vinyl chloride and/or dioxins or other contaminants until proven otherwise,” she said.
而且当地的人观察到很多动物都死了?。。这可能是直接泄露造成的不是dioxin造成的吧。。基本中部那个river basin水系影响就比较大了。。五大湖区可能是dioxin影响大。。 |
