GenericOverusedName posted:A lot of chemical names are basically just german compound words that describe the structure, if it follows standard naming conventions. Hardest part for that compound is the first part on the right, isowurtzitane. It is describing the shape of the weird carbon cage, but that's not something you run into often like an propyl group or whatever so it's a weird word for a weird cage. After that you have hexa (6) aza (aromatic nitrogen stuff), so six nitrogens in that cage structure replacing some of the carbons, and then hexa (6) nitro groups attached to it. I always remember isowurtzitane because one of my Ochem teachers was a dick and put it on the first test.

I've done a little bit of computational chemistry in my life and I can't think how the gently caress that thing works. "Bond Angles", they're just a theory dude.

Rigged Death Trap posted:Its mainly intesting for the above reason. It's also a pain in the rear end to get dry, we had to run two separate distillations over sodium, with all the fun of having to switch the boiler flasks from under the drying apparatuses when we needed to refill the pre-dry one. And the fact that it's perfecly mixable with water can mess with extractions.

SLOSifl posted:It sounds perfectly safe...they said there is at least two feet of sludge on top to prevent fires. I don't know but that sounds like plenty of sludge, right? It sounds like the sludge is the White Phosphorous. So it's water and plastic balls on top of the sludge. I put this here since I am the furthest thing from a chemist. I am inclined to believe the potential worst case possibility. I am also open to possibility that this stuff has been sitting out in the weather for so long that it's contaminated with enough dirt and whatnot that it might just be a toxic hellhole and not a flammable toxic hellhole.

The whole town is a giant Superfund site, and most of the bodies of standing water have to have bird deterents because it's not unusual for a flock of migrating geese or whatever to dissolve en masse in the Berkeley Pit every few seasons. But don't worry if you visit. They pump the drinking water in from an aquifer on the other side of the mountains. Also, get the fried pork chop sandwich. Just trust me on that. Goddamn, now I wanna go to Butte, and I totally could have last week. Missed opportunity for a casually racist fried meat sammich and some quality OSHA.txt pics for my Instagram.

https://en.m.wikipedia.org/wiki/Berkeley_Pit It's an old open pit mine that was shuttered, but the water is so acidic that it is very not good for anything living around it. There are actually such high levels of dissolved metals that they can mine the water for copper. It is still a couple decades before the water in the pit gets high enough to hit groundwater, but it will be there soon if it doesn't get treated somehow.

The Berkeley Pit is filled with highly acidic water that also contains high concentrations of heavy metals and other unpleasant chemicals such as arsenic and sulfuric acid. It continues to get worse naturally because the water in the pit is slowly dissolving the rock around it, leeching more terrible things into the water. The chemicals kill the geese. The water just dissolves the corpses.

I shouldn't be surprised, considering what thread this is, but I guess there's a big mental difference between "yeah don't touch this if you like your limbs, but don't be a dumbass and nothing bad will happen" and "this is currently and actively causing living things to dissolve out there in the real world." Thanks!

I posted a bit about the Pit, and Butte in general, in the Montana thread a while back: https://forums.somethingawful.com/showthread.php?threadid=3822630#post473013024 With bonus pictures! Yes, it's that color. It's much more intense if you fly over, because you get a real sense of how deep it is. Literally looks like a gash in the earth that's full of blood.  The most recent geese-kill was last winter. Something like 10,000 birds were killed, and there was a state-wide warning not to eat any wild goose-flesh and to deliver any carcasses to the state for necropsies. A goose was taken to a veterinarian in reasonably good health, but died a few days later. Whatever's in the water is generally fatal to most living things, never mind that it's so acidic that it ate the last boat ramp a while back and they haven't been able to put anything on the water since. Made collecting the goose caracasses a loving chore. If I remember right, they had to swap boats out after a few hours anyway, otherwise the hulls would get eaten through. Oh, but there are nematodes that thrive in that toxic slop! Last I heard, they're being researched for potential cancer fighting agents. Life finds a way...

Turns out, mining is bad. There's a mine in Queensland, lead/zinc/silver, that closed down in 2015 as it was played out. I was chatting with one of the enviro engineers at that company a few weeks ago and the rehab they're scheduled to do under Australian law is going to cost them basically as much money as they made by working the mine for the six~ years they owned it. They bought it in 2009 with the understanding that they could expand it quite a bit. Then a Native Title claim turned up and put an end to those plans. It's probably going to drive them bankrupt.

The site I'm working on at the moment has hectic environmental stuff. Like if there's a chemical spill (we only really use diesel and hydraulic oil on site being roadworks) on the alignment or any part of the site they have to stop work, remove the dirt until they find clean earth in all directions, go a bit further, then refill with clean earth. It can be painful like when there was a 200L oil spill the other week it cost us half a day all because a hose blew on a scraper

Now that just makes me want to go back and find the review paper I did on those types of extremophiles in undergrad. Friggin' bacteria in heavy metal mining waste that could make armor (proteinaceous shell) out of things like gold, lead, even a case where it happened with uranium. EDIT: from a post I did last year actually: RedneckwithGuns posted:This is in response to the poster asking about ways microbes deal with environmental contaminants like heavy metals a bit ago, but I finally found this paper I cited a few years ago about a strain of B. sphaericus that uses heavy metals to literally make armor for itself RedneckwithGuns has a new favorite as of 23:43 on Jun 21, 2017 |

Turns out that if that happens to you, a Really Good Idea is to keep quiet about it and soak it up yourself with kitty litter, because if you call in the pros it turns out that they have to do this same thing. In my friends' case they had to excavate about a 10-foot-square chunk of their basement floor down to 6 feet, haul all the earth out in buckets, and treat it as toxic waste. Cost something like $20,000 all-up.
