The EPA, the Centers for Disease Control, and 30 major industrial countries all think this is much better for the environment than the oil.
The environmentalist whackos say otherwise, as does apparently the Russian minister of energy or something like that.
In my opinion, these people are not "experts", they don't seem to know how this stuff actually works, or what it's properties are. The people we pay to make these decisions certainly have come to a different conclusion.
And before you tell me that I can't trust the EPA, when is the last time you remember the EPA saying something that was dangerous is actually SAFE? They are known for telling us that safe things are dangerous.
And when is the last time the CDC told people things were safe when they were not? Isn't the CDC the group that had us all worked up over the swine flu?
Government doesn't underplay things, they are paid to overregulate.
What I've read indicates we have all the ingredients, what we don't have is the relative concentrations. I posted the ingredients above this post in a table format, along with a list of household items that use them.
“I posted the ingredients above this post “
Thank you very much for doing this. This is far more useful than listening to some Green’s babble. Get the numbers. Get the ingredients. It’s the start of moving towards an answer.
Never look diretly at “Corexit” ....
But seriously, I think this is all bad news ....
There are many freepers here from big pharma and big agra that carry water for their masters, I’m sure they are a few who will carry water on this issue here too, they are easy to spot as well.
It couldn’t be that they actually believe in what they do for a living, and are trying to provide their expertise?
No, you’re right, that could be it, it’s just that they’re wrong and in large part brainwashed/uneducated ...
Which will be about to be ignored...
However, the Corexit is separating the oil into its constituent parts, harming both the ocean and the air.
1,250 barrels of Corexit treating 1.6 million barrels of crude oil is doing all of this, rather than the 8,000 psi wellhead pressure, the 40% methane concentration, the mile long transit from release point to surface... So if they cease to treat the oil at the wellhead with Corexit, then everything will be just fine, and we can use all the great traditional clean up methods.
Sorry, I've run out of suspension of physics for this week.
I was at Pensacola Beach yesterday and ate supper at a beachfront restaurant while witnessing the giant photo op of a clean up.
Funny that the only beaches that were closed were the only beaches that would support the caravans of buses and media trucks. Just a half mile away the beaches were open and people swimming.

Personally, I wouldn’t want prolonged exposure to Skin cream, body shampoo, Baby bath, mouth wash, face lotion, Body/Face lotion, tanning lotions, Wetting agent in cosmetic products, Household cleaning products, Air freshener, or cleaners.
And I certainly wouldn’t want it in my eyes and I wouldn’t want to be inhaling it all day long. Unfortunately for our fish and other wildlife, they have no choice.
There are some dispersants that are as safe as drinking a cup of coffee (I know this for an absolute fact). I don’t recommend you drink Corexit 9500. Some of these would be cheaper too.
Yeah, it might be okay to touch skin cream, body shampoo, cleaners, household cleaning products, etc., but I wouldn’t recommend ingesting it or prolonged exposure.
“I think this is all bad news ....”
Well, of course it’s not good news. It’s difficult to paint an ecological disaster as an Ivory Snow commercial. The situation is what it is. Pols will fight it with sound bites and photo ops, as they have neither expertise or capabilities to solve the problem.
Practitioners, on the other hand, tend to actually DO something about the problem. As yet, there is no perfect solution to the problem facing them. However, they know more than most about what will help the situation. Given the environmental problems we’ll be facing in the short term, I’m not willing to go “all wobbly” when it comes to taking constructive action.
Now, there are those that will go into hysterics simply from what their friends tell them. Others, will forgo parroting the PC mantra and actually expend the time and do some research. It’s not that hard with the internet. What is disheartening is listening to the number of folks that clearly don’t have a clue about what they are talking about. I’m specifically referencing the enviros, and their fellow travelers of the day, the press.
Neither is particularly well educated about the particular subject they are holding forth upon, yet that does not stop them from turning their amp volume up to 11. To listen to them, one might think they were politicians themselves. In truth they are minions of the same, which gets into agendas, and dark alleys that I’m not really not comfortable walking down.
I can’t emphasize this enough. Do your own research, if you are really interested in the problem. Don’t rely on others to do it for you. Most people are quite happy to be led, which accounts for why the country’s in such a pickle of late. There’s no reason you have to make the same mistake.
Thank you.
It's the argument of deceit, to put words in the mouth of one's adversary, then to diecredit them.
Choose your sides wisely.
Or, in this case, if you really wish to, keep arguing that the dispersant they are using is ineffective, therefore they should keep using it. I think I might find more challenging arguments at DU or HuffPo.
BTW, have you seen the video of the jets they are spraying into the petroleum, at its point of entry? BTW2, are you an expert in this field? I have communicated with one. Maybe you would like to be introduced. (Don't worry, this last paragraph is rhetorical.)
They didn't. The EPA asked them about this, and BP responded, and the EPA agreed with the response.
The statement is correct.

Thank you for the ping.
Your argument: the dispersant is harming the environment and will be a significant toxic source, and should be ceased immediately, and other methods used to clean up the crude oil spill. No words put in your mouth, that is your argument. Please correct me if I am not summarizing it to your satisfaction.
My argument: This isn't a crude oil spill in any conventional manner. What reaches the surface is a separated petrochemical spill that can be broken down into four major groups:
Use of underwater or surface dispersant is immaterial to the component parts I listed - that's what reaches the surface anyway. But using the dispersant helps reduce the damage done by that medium oil.
Now what about the toxic concerns of the dispersant itself? Bleach is a toxic substance. You absolutely don't want to drink the stuff. But put a few drops into contaminated water, or into water that will be stored for long time, you make it drinkable. The source material is deadly - you drink that bleach straight up, you could easily suffer severe health effects. But diluted, it serves as a very helpful substance.
The same can be said for the dispersant. Toxic alone, but so diluted by the volume of water that you're dealing with that it the beneficial effects of breaking apart that medium oil into smaller droplets outweighs any toxic effects.
I know this is completely against the propaganda you've been posting on here, and digs hard into the conspiracy theories, but if you've a credible source that disputes anything I've said in here, I'd love to read it.
The only component material in the dispersant that is not contained in larger quantities in the spill itself or the ocean environment is sulfur, and the sulfur content, according to material safety sheets, is about 6%, or when put into context of release amount including the spill itself, about 4 ppm. Enough that it would create an odor if the spill was on land, but mixed with the trillions of gallons of water in the gulf, unmeasurable by any scientific devices I know of.
To summarize: This isn't a conventional crude oil spill which we can use all the tricks and toys that we've designed over the years. The toxicity of the dispersant is diluted enough to pose no major health risk. Not using the dispersant leaves pools of medium oil which is difficult to clean up due to the surrounding tar solids, and poses a significant risk of damage to the ocean environment.

I guess i don’t understand the chart you posted. IT looks like the Corexit has the lowest “toxicity number” in your chart for both 24 and 48-hour. But I have no idea what that number means, or if smaller is better.
