Just sickening. I read briefly of this incident 2 days ago.... and just read this above Eric. I searched also just now and found a CNN article - "After a train derailment, Ohio residents are living the plot of a movie they helped make" - which goes into the movie made their and nearby about - you guessed it - a freight train collides with a tanker truck. Just a year ago. "White Noise" it is called.

Never once mentioned in it are Dioxins from Vinyl Chloride, and that CNN article states only 5 train cars contained vinyl chloride. Butyl acrylate is what the article more focuses on....briefly at that. How many people downwind did it or will it effect? For how long? Did the weather balloon stories in the USA block all other news?

So easily tens of thousands of people were directly exposed by the airborne chemical plume and I daresay that it may well have been even more once future research reveals how truly widespread the plume travelled as it dispersed at lower amounts much farther than initial tracking could determine. Then throw in thousands from water poisoning also likely to become higher too. Here's a plume animation map to get you started: https://aircocalc-www.createlab.org/pardumps/plumeviz/experiments/video/ohio-train-fire/20230206.mp4 I have more maps but it's late and I got to go to bed now..

Would it be possible to access this map more zoomed out and up to date ? Living in Toronto and would like to assess how bad it could affect us up north. Thanks

sorry that's as far as the animation extends both spatially and time span. I haven't seen any other platforms that charted the plume's vectoring besides this one. Given that the last vector was northerly and that the prevailing winds of the jet stream are typically from west to east it is certainly feasible that Toronto may have received a diminished fall-out later from the plume but there really is no way for me to explore that at this time. Nevertheless, Toronto's exposure had to much, much less just because there would have been a lot more dispersion before any smaller fall-out strands reached Toronto. Best.

Update so I did find an image of particulate distribution on Feb 8th two days after the controlled release but I haven't been able to follow-up any further but I wanted to share it with you: https://twitter.com/HallidayJ12/status/1626692130944045071?s=20

It was a reply tweet to a tweet from a person in Guelph Canada who noticed a strange substance ccovering his car here: https://twitter.com/bhohner/status/1626253173299068932?s=20
