Link? That sounds like a channel I’d be interested in And this got the attention it did because it’s far more severe then one load of tar/bitumen in a river - and far more toxic made potentially worse from the choice to. Burn it off to clear the tracks faster

Youtube has a lot of them. Here's one about a derailment in Nashville. https://www.youtube.com/watch?v=0dZT7TTQqb4 Here's the one I mentioned about a derailment in middle of nowhere Iowa that dumped tar into the creek. https://www.youtube.com/watch?v=-HpL0Xk9jTI Here's one of those local news reports: https://www.youtube.com/watch?v=1_pKVdv-Y6Y

Phosgene also has very low environmental persistence. I think the actual amount of dioxin created from combustion of vinyl chloride monomer at atmospheric pressure is very low. In any event, both were dispersed into the atmosphere at concentrations that pose(d) very little danger to people outside of the temporary evacuation zone.

My friend from East Palestine took a video of the water in a creek that runs outside his house. The water is rainbow like an oil spill. This was yesterday. Whatever they combusted and dispersed, it's very much still there and I sure wouldn't want to be drinking that water.

They burned off the vinyl chloride because the combustion products are relatively benign, it was much safer to remediation personnel to ignite the chemicals in a controlled burn vs having them work around flammable chemicals for weeks, vinyl chloride is quite volatile and acute exposure to high concentrations of vinyl chloride vapor is dangerous, and they wanted to get everyone back in their homes (and yes, get the r…

iron oxidizing bacteria often produce that sheen when disturbed

one way to tell is if the sheen, when itself disturbed, stays broken into pieces (bacteria) or rejoins together (oily)
