Howdy - I don't know if "addressed" is the right word. Commented on, but not given sufficient perspective. Having said that, the problem is incredibly complex, so there should be no expectation that Mr. Oliver's video or any other single thesis on the topic could possibly suffice.

Your "one chemical bond difference" is an appropriate consideration, but with recognition that once we reach on the order of C20-C40 length dispersable or emulsifiable molecules as surfactants / surface energy modifiers, the insoluble polymers come into play, with not 30'ish bonds growing one at a time, but leaping to 20,000 or more. No doubt the pool has already been irreversibly pissed into by the irresponsible producers that convert small molecules into very, very large ones, but with some control, responsibility, and integrity in our industrial process owners (yes, hell just froze over) there is no reason why we could not safely continue to produce the polymeric forms of PFAS. We do so for substantially more toxic chemical conversion processes today.

It's interesting to note the (usual) examples brought forward by others in this post (Teflon cookware), just waiting for someone to mention Gore-Tex, but by far the biggest impact won't be on consumer goods that we all touch regularly and recognize the name brands of, but will be on the industrial / commercial uses of these polymeric families that are pervasive in the systems / processes that we all derive benefit from every day. Ironies exist, that perhaps confuse the "all PFAS are bad" premise ... consider - effectively every seal, gasket and control valve in a water purification plant is most commonly made of a PFAS polymeric compound, PTFE included, all tested to rigorous specifications and compliance by specific agencies that do nothing other than deal with potable water (thankfully not the EPA - it's National Sanitation Foundation (the other NSF), or Water Research Advisory Scheme (WRAS) in the UK etc.) .

So my contention and the view of many in the end user community is that it's not the final form of some of these compounds that are bad, it's the horrendous messes we leave producing them. We can't unwind our Clock of Dumb, but killing the entire crop just to get rid of the long ago seeded weeds doesn't solve the actual problem, it makes it much, much larger.

Thanks for your comments.

According to wikipedia, bearnaise is "a sauce made of clarified butter emulsified in egg yolks and flavored with herbs".
It is not made of bears and mayonnaise.


Someone has obviously tampered with the article.

LIES!

He is saying "propanediol" & propylene glycol...
A quick wiki search tells me that propanediol can be formed by "Conversion from glycerol (a by-product of biodiesel production) using Clostridium diolis bacteria."
...so could bacteria be breaking down components of the oil into propanediol/propylene glycol? ...not necessarily that it had to have come from the Corexit? Just wondering....


"In response to public pressure, the EPA and Nalco released the list of the six ingredients in Corexit 9500, revealing constituents including sorbitan, butanedioic acid, and petroleum distillates.[3] Corexit EC9500A is mainly comprised of hydrotreated light petroleum distillates, propylene glycol and a proprietary organic sulfonate.[16] Environmentalists also pressured Nalco to reveal to the public what concentrations of each chemical are in the product; Nalco considers that information to be a trade secret, but has shared it with the EPA.[17] Propylene glycol is a chemical commonly used as a solvent or moisturizer in pharmaceuticals and cosmetics, and is of relatively low toxicity. An organic sulfonate (or organic sulfonic acid salt) is a synthetic chemical detergent, that acts as a surfactant to emulsify oil and allow its dispersion into water. The identity of the sulfonate used in both forms of Corexit was disclosed to the EPA in June 2010, as dioctyl sodium sulfosuccinate.[18]" wiki

I quit, but before I did I tallied all the time on all my characters that were above level 10. Didn't delete them, but I'm not playing (or paying) anymore.

so.. total

days: 117 + 2 + 5 + 1 + 1 + 2 +1 +16+3+11+1+4+3+13+20 = 200. heh!
hours: 11+3+1+15+20+6+9+9+17+18+10+14+13+15+18+9+2+15+7+13+14 = 239 hours
minutes: 11+5+57+44+59+45+48+59+3+14+20+4+42+29+11+8+19+34+21+15+42 = 590 minutes

590/60 = 9.83, so 9 hours, and 50 minutes

239+9 = 248/24 = 10.333, so 10 days, 8 hours

210 days, 8 hours, 50 minutes.

I think he did propose a solution. He basically said "leave it as a two dimensional problem." The skimming and booming would all be easier to accomplish if all the oil is on the surface, rather than emulsified with the water.

>> ^alizarin:

Oil doesn't evaporate into rainclouds so it can't be "raining" oil unless there was a waterspout (unlikely).


What about if the oil is emulsified with water using dispersants? Don't the dispersants effectively break the surface tension of the oil? What effect does that have on evaporation temperatures?
