That absolutely does not support your point.

At best , it says the covalently bonded form is sometimes called cyanide, but it does not assert that the negative ion is EVER referred to as "nitrile."

My argument is than plenty of untrained people exist who might not know that the covalent of bonding with transition metals is not equivalent to the ionic bonding in NaCN, even though both types of compounds are referred to as "cyanides."

Yours is (apparently) that a trained chemist should be incapable of distinguishing the sigma bond formed with an alkyl group from the bonding with a transition metal (including pi backbonding with d orbitals), even when one is called "nitrile" and the other is called "cyanide" or "cyano."

You are absolutely right and I believe yours is the best nitrile and cyanides chemistry answer in this whole thread.

Delving in, if I may just add a few things you might have missed, as a retired organometallic chemistry professor myself at the renowned university of Antemortem Cornucopia, Michigan (founded in 1666, making it the oldest US university).

NaCN with its C≡N cyano group makes a really great cake topping. We actually use it at our annual university parties all of the time, plus it goes great with any pizza. It's been proven by the Boondoggle Beer University's biochem department in '69 ^[1] that the C≡N cyano group, whenever coupled with NaCl‑rich and spicy or sugary foods (due to its covalent bonding to all of these), activates several taste bud natrium channels at once, crucially and significantly overstimulating the sensory taste inputs of the human brain.

Without doubt, such research results raise some important and significant potential for NaCN use as a novel food additive, one that would crucially both be safe and able to increase both the taste and health benefits of any highly processed foods considered unhealthy.

The weird "pro-lead" lobby frightens me even more than the tobacco lobby and their current obsession with once again getting a whole generation hooked on, this time, vaping.

And I say that as someone who works with leaded solder, but, and this is key, I'm very careful with it, wash my hands after working with it, and always make sure whatever joints I'm soldering are tucked away securely inside the devices I work on where they won't cause any harm (that, and making sure my joints aren't cold which risks a break and a loose bit rattling around in there).

And, I hope, using proper ventilation while running hot lead.

Have you met the DDT zealots? They're a bunch of fun.

 

[Edgar Allan Esquire]

Have you met the DDT zealots? They're a bunch of fun.

I remember reading the pro DDT rant in Make room, make room and thinking it probably hadn't aged well. Although, with scifi in particular, I have a hard time telling when a character is the author's soapbox proxy or not.

 

[Dark Jaguar]

And, I hope, using proper ventilation while running hot lead.

That's a bit of a misconception. At the temp that solder melts, lead isn't getting vaporized at all. There's no danger of inhaling it. That said, I absolutely use proper ventilation, because the OTHER elements of solder, like resin, DO smoke at that point and they're bad for your health too. Also another misconception. Touching lead isn't dangerous like it is for mercury, ingesting it is, so the key is to make sure that all work surfaces are cleaned after solder work, as well as your hands of course, to prevent accidentally ingesting any of it. It's only toxic under those circumstances, but if that's met, even the tiniest flake can do long term damage, so yes, I take it seriously.

They're all like "If we'd kept DDT we wouldn't have malaria!!!!!"
No joke.

There are people nostalgic for kids chasing behind the DDT wagon spilling out poison through the neighborhood? That's the description I remember a stand-up comedian giving for it, along with the nightmare that was "lawn darts" as a game, for kids, on purpose.

If malaria becomes a bigger problem in the US, I'd much rather have to invest in mosquito nets and empty out standing water after storms than deal with poison clouds.

Your premise is false, so your conclusion is worthless.

The opposition is largely driven by large-scale events such as happened at Chornobyl, Three Mile Island, Fukushima. Before each of these events, the public was assured that the existing technology was safe. This leads to the view that even if the specific problems encountered at any such event are addressed, the ability of "experts" to predict the range of possible incidents is insufficient.

As an example, at Three Mile Island it became clear that a nuclear plant losing power could lead to problems, since some of the safety systems were active. This led to new regulations, such as the requirement for an emergency generator at all sites with similar technology. Fukushima had an emergency generator. But the generator, along with its fuel, was stored in a basement where it was flooded out by the tsunami which triggered the incident.

Add to this the fact that there is no available means at the moment to dispose of high level nuclear waste, and the fact that nuclear is the most expensive source of power there is when you factor in cost overruns and delays. Radiation emission from a properly functioning nuclear plant has never been an issue, except for the most lunatic fringe.

It's weird, they call it Antarctica, but it's cold too! It's not the opposite at all. If Antarctica and Arctica touch, do they annihilate?

 

[Faceless Man]

I think if Antarctica and the Arctic touch, we have bigger problems than wondering if they'll annihilate each other.

Well, maybe not bigger as such, but I don't think we'll be worrying much about it at the time.

I just looked up a Wikipedia article on this person. Sounds like she did some amazing conservation awareness work. It's weird they found someone to blame for ALL of conservation I guess. It's like how flat earthers, who actually do believe what they say, seem to blame "NASA" for perpetuating the round earth "lie", as if NASA has that power, or as if the idea of a round earth didn't precede NASA by millennia.

She became a lightning rod specifically because Silent Spring was the book that started the movement to ban DDT, which was, at the time, the leading weapon in fighting malaria. Except that, as I noted above, many species of Anopheles were already showing signs of resistance, and the problem, apart from the general toxicity, was that it was being used in excessive amounts in agriculture, was poisoning groundwater, killing off all insects, not just crop pests, and that was causing a severe decline in bird populations that fed on them. (Hence the "Silent" part of the title.)

Year by year, one less species of bird song can be found in the spring chorus.

Only if Morlocks like living in a hellishly hot uninhabitable desert...

Or a hellishly cold frozen supercontinent. Depends on the scenario and global climate prediction 250 million years into the future ain't exactly exact.


Personally, I am rooting for Pangea Ultima – that one looks at least somewhat liveable with that nice inland sea, unlike the other three...

There's no such thing as zero radiation exposure. The Sun pumps out gamma rays and x rays, the Earth is bombarded by cosmic rays from the rest of universe and radioactive decay of elements in the environment. There's enough Potassium 40 in 1kg of soil to produce 300-400 Bq

The comments section of this article are a good example of how chemophobia and radiation phobias have taken hold of our collective minds and society. Lots of quips about glowing in the dark, and growing new appendages, and feats of miniscule "exposures" to substances that CAN be toxic if taken into the body in sufficient quantity, but " generally safe" at small exposures.

How many of you remember the panic that occurred when the law was passed that required the removal of any product that a child might access, and which might contain lead? There was a panic because books printed before about 1985 might have ink that contained lead. I haven't looked to see if it was subse

But the generator, along with its fuel, was stored in a basement where it was flooded out by the tsunami which triggered the incident.

The way that you describe these accidents indicates that you have no background in nuclear power. First, the TMI accident did not occur because of "a nuclear plant losing power". It was caused by a loss of feedwater, which led to an orderly shutdown of the plant, which was complicated by a stuck open safety-relief valve for the pressurizer. The stuck-open valve was not identified for 2 hours, and the operators turned off the safety injection system, which had properly started to deal with the stuck open valve. It had NOTHING to do with a loss of power, of any sort.

There was no "requirement for an emergency generator at all sites with similar technology". All nuclear plants in the USA have emergency diesel generators to supply power if offsite is lost. I believe that this is even true at ALL other commercial, and even military reactors, around the world. There was a publication by the NRC that describes all of the "lessons learned" from the accident - "NUREG-0737". It is available online. go read it, if you want to be educated about TMI.

The emergency generators and their fuel at Fukushima were not "stored in the basement". They were permanently installed these. The electrical switchgear for those generators were also installed in the basement, below the level of the flooding from the tsunami. The DC batteries for control systems were located above the flooding, and continued to operate for about a day, until they were exhausted, even though the operators tried to install replacement car batteries. It is not clear why TEPCO did not bring in small temporary generators to recharge the batteries. I have not seen any analysis of that part of the event. In any case, the accident at Fukushima was a "cultural accident". This was the assessment of the Japanese Diet, which published a report on the matter. https://inis.iaea.org/search/search.aspx?orig_q=RN:44017394. You should read it and try to understand what it says.

The flooding of nuclear plants is something that has been considered since the very first ones were built. However, with time, many sites were discovered to be more susceptible to flooding than was originally imagined. The last 2 (of 6) reactors at Fukishima were built at a higher elevation, and did not suffer any flooding from the tsunami.

Interestingly enough, there was a significant flooding even in France, in 1999, at the Blayais plant near Bordeaux. most people have never heard about this, but the nuclear regulators were all told about it, and most of them required revisions to flooding protection civil works around plants, as well as preparations for complete loss of power in case of flooding. I know that the USA and other countries did this, but evidently the Japanese did not consider it to be important for Fukushima 1-4. (See the report about "cultural issues" above.) So, when the tsunami occurred, they lost all power. (unlike TMI, where they NEVER lost power)

So, since you have no background in nuclear energy, I would suggest that your first sentence is just bluster. You are also probably young, and did not experience all the demonstrations and protests against nuclear during the 1980s, after TMI. You should also go read some newspaper articles from that time, and history books.

While any ONE source, like these plates, is unlikely to cause cancer, an aggregate of them, like say if they put that "coloring agent" in everything the light touches (like plastic is today), could certainly raise doses to worrying levels. So, it's good to nip these things in the bud every time they appear, because it's simply a fact that when it comes to the market, what isn't forbidden is compulsory.

Almost all big industrial accidents of yore are "cultural accidents". As are most of the cyber accidents like CrowdStrike most recently.

Turns out that your own common engineering culture of 'ignoring the human factor' might not be the very best idea when the result can be so catastrophic, because Humans are not Vulcans...

But what do I know, being just a poor human sciences major schmuck, frankly not quite experienced enough to critique your glorious engineering that always works, at least until some poor tired human fucks it up in the Swiss cheese hole manner... /s

Oh, and what do all the aviation safety regulators know, which are among the very few who do worry about the human factors like fatigue and confusion and instead of downplaying them, are actively trying to deal with or around them? Maybe ask them first.

You totally ignoring all the obvious cultural or human design issues, I wouldn't trust you to build a bridge over a two metre stream if you were an engineer. Let alone a NPP.

 

[The Wonderful Wizard]

Important to remember--they did not know these things were poisonous in the 1800s . Heck, we didn't even remove lead from gas until the 1970s and lead from paint until 1978. These chemicals are in guiding, and in every paint prior because they made the colors brighter and adhere better without flaking or peeling. You are likely to have them in any pottery prior to 1980 that you might have; since it was in the glazes and paints in use.

Lead paint works better to preserve wood than modern exterior paints, because it soaks in and doesn’t crack and hold water behind the paint.

Copper chromium arsenate was still commonly used in developed countries to tanalise (which I only just discovered was a trademark for pressure treatment in general) exterior wood into this century - that distinctive green is still sometimes seen.
