Sarin (Nasty.)

I wonder if wearing that outfit eliminates the normal urge to pet the fuzzy animal and say something either obvious or nonsensical in the babytalk voice.

On the more serious side, I for one am very glad that Germany decided that using nerve agents during the second world war wasn't worth the risk of reprisals. One can hardly say that the war went well; but had the available tabun and sarin been used...

It's interesting how sarin figures into one of the untold arms races of World War II -- from what I've read (caveat Wikipedior) Sarin and a chemical relative, Tabun, were part of Nazi Germany's research during WWII into organophosphate weapons. They were evidently working on it quite urgently as well, as they took it for granted that the Allies were doing the same research as they were (it was true for the atom bomb, right?). But when it came right down to it, they never got around to using it... and the Allies had never even broached the question.

There is a story somewhere about a German chemical weapons factory worker who got two liters of tabun dumped down the back of his hazmat suit. He was dead before anyone could even open the zipper.

There has been research into making sarin last longer. In theory, you could incorporate it into a binary weapon so it wouldn't get mixed into a single compound until actually deployed. The shelf life could be as long as five years that way. Such is ingenuity.

In my organic chemistry course we went over the use of binary munitions which allows for long term, ready-for-immediate-use storage for this chemical munition. A faulty memory was refreshed with the help of wikipedia: Isopropanol, isopropyl amine and methylphosphonyl difluoride.

Weaponized US nerve agents were typically stabilized with 1-3% diisopropyl or dicyclohexyl carbodiimide. Over time the muck Officially gelled, rendering munitions notably difficult to neutralize. The charges might have been purposely thickened for adherence and sustained contamination vs. evaporation. War agents seek to disable, wound, and mutilate not kill. Corpses are disregarded. Casualties bog down immense infrastructure, financial, and personnel resources. Hiroshima and Nagasaki were historic not for burning and crushing but for radiation effects later.

In 1918 German corporal Adolf Hitler was temporarily blinded by a British mustard gas attack in Flanders. Steep learning curve. Bush the Lesser will be historic less for spending the NSF's annual budget each week annoying Muslims than for creating some 80,000 chronically disabled veterans. That alone will be a $billion/year in expenses, forever.

I can verify that Brian X. I can't remember where I read it, but IG Farben was doing a lot of work on organophosphates before, during, and after WWII. They are used as insecticides as well as chemical weapons.

Considering the extreme toxicity and speed of tabun, I suspect no one bothered to try and open his zipper.

I remember that 15 years ago DIC was an inexpensive peptide coupling reagent, almost as cheap as DCC.

It turns out it was the sarin stockpiling that made for diisopropyl carbodiimide to be a cheap chemical - DIC was manufactured for army as a Sarin stabiliser additive, to eat the acid and moisture traces that ruin sarin over time! Unfortunately, it was later found that the formed diisopropyl urea produced over time in the sarin ammunition ...congealed. The sarin in the US legacy chemical ammunition is perfectly viable but it turned into a jam - which makes it very hard to dispose of as it cannot be simply drained out.

Now Sarin is no longer stockpiled the DIC became pretty expensive again.

Back when my dad was in the Army, he was part of the Chemical Corps, and over the years I've heard all sorts of interesting stuff about the various chemical weapons, including just how nasty and deadly sarin is.

Flash forward to around 1995 or so -- I'm off in a remote corner of Bulgaria teaching conversational English to highschoolers, when one of my students tells me of what was on the news the prior evening -- the Aum Shinrikyo sarin attack on the Tokyo subway. The conversation went something like this:

"Did you hear about the nerve gas on the Tokyo subway last night?"
"Wait, what??"
"Yes, some cult used sarin. 10 people died."

"They used sarin, and ONLY killed 10 people? Someone f***ed up...."

It's a good thing, then, that we only have a little over a half-million pounds of the stuff down here (and, that's only about 1.7 percent of the country's stockpile!).

When I was a child we lived about 2 kilometers from the biggest chemical weapons storage in Russia (http://www.globalsecurity.org/wmd/world/russia/kambarka.htm).

The scary fact: we didn't even know about it.

Drug Testing is the best way to deter your children from using illegal drugs.

Should you drug test your teen? Will this cause your teens to feel like you are disrespecting them on their �home� turf? Are you ignoring the fact that your teens can get drugs even easier today then ever before?

It�s time as a parent to step up to the plate and confront your teens!!!

Drug use and prevention is one of the most frightening discussions you will ever have as a parent with your teen. According to one recent study, teenagers whose parents talk to them on a regular basis about the dangers of drug use are 42 percent less likely to use drugs than those whose parents don�t. As difficult as it is to bring up the issue of drug use with your teen, simply talking about drug use may not be enough to fully protect your child from experimenting with and using drugs.

How can this be solved? The answer is simple. In-home drug testing! If your teen knows you have the ability to perform a drug test at home on a moments notice, they are going to be even less likely to experiment with drugs. In-home drug testing can be an extremely powerful deterrent tool in preventing drug use! It becomes an �easy out� to peer pressure as well. Your teen can tell their friends, �No, my parents may drug test me when I get home and I have to be clean or they will ground me� take away my car� wont let me go out�� Isn�t this worth providing piece of mind as a parent knowing that your teen is held accountable for their actions?

DrugFreeNetwork.org is a great resource to buy in-home drug testing kits. The drug test kits come with a 10 panel urine drug test, an alcohol test, and a nicotine detection test. These tests are affordable, simple to use, and give accurate results within 5 minutes! One of the best tools in the kit is the contract that parents and the teens sign stating that they live in a �Drug Free� household. Also included in the kit are lists of local resources for counseling and treatment centers as well as a guide to parents which discusses the signs and symptoms of drug use, the many types of illegal drugs, and dangers associated with them.

In addition to using these simple to use drug tests as a deterrent, you could actually save your child�s life by identifying a problem with drugs before law enforcement or school personnel intervention or even death!

Not completely true--the Nazi's did use nerve agents against the Warsaw uprising.

To comment on what Uncle Al said regarding sustained contamination vs evaporation: I am a Chemical Corps soldier and over the course of training we covered nerve agents of course. there are basically two types, persistent and non-persistent. Sarin is classified as non-persistent in the G series of nerve agents. The G series is used to rapidly produce casualties in an area to later be occupied, usually preceding an infantry assault. V series nerve agents however, are oily and do not evaporate very quickly at all, normally used for complete terrain denial. So, the thickening of Sarin actually wouldn't make much sense when other agents, such as VX are already available.
