Heavy water is only 11% heavier then normal water and a little bit toxic.

Oh, there you go again, Bestonnet_00.
Spoiling a perfectly good scam with the facts. Sheesh!
Okay, I'll only put a 11% markup on the heavy water and throw in a stomach pump.
You drive a hard bargain, but I'm ABSOLUTELY sure (Glory be, don't cha know) that I'll make a believer out of you. After all, accidental death on your part just reflects your lack of FAITH!
(I've also been told I'd make a good palmist and a good terrorist. Now if I can just figure out how to merge the two into Terrorist Palmistry)

Pthalates referes to a group of organic (having C-C or C-H bonds) solvents that are used as plasticizers in plastics. A plasticizer is a substance that is added to plastics or other materials to make or keep them soft or pliable.
By putting water in a plastic bottle, it becomes contaminated with pthalates. Some of these pthalates are suspected carcinogens and are on EPA 8270/625 list as standard monitoring compounds for toxic waste.
Any health benefits that may be touted by any given water are destroyed by putting it in a plastic bottle.
Pure, clean drinking water is a good thing, but organic solvent contaminated water in a plastic bottle is no different than tap water (trihalomethanes up to 50ppm, if your water provider chlorinates your supply).
When I was running HPLCs (high pressure liquid chromatography) and GCMS (Gas Chromatograph Masss Spectrometry) we'd have to take special care not to even touch these plastics as they'd show up as huge comtamination peaks on our runs.
I'm glad I don't do that anymore.

Well, that's a lovely thought. So I guess I'm really screwed, drinking tap water from a plastic bottle! Yeesh...
Thanks for the explanation Bozola.

11% mark up on Heavy Water?
Thats crazy considering it costs a lot more then normal water.
Oh does anyone know where I can get a GCMS for $20?

5890 GCMS
Not $20, but still a great deal for a fantastic piece of analytical equiptment.
Of course it doesn't include capillary columns or roughing pump...and if you want to do water analysis you'll have to purchase the Purge and Trap separately (I've always liked the OIC 4560 concentrator with the DPM-16). That'll cost a bit.

Some plastics like Nalgene poly-carbonate are EXCELLENT! Originally, they were specially designed for the biotech world, but long ago they became a favorite of hikers. Low or no pthalate contamination from these bottles.
It's not that the pthalate contamination is really bad for your immediate health; there's far more serious daily dangers (herbicides, smoking, alcohol, gasoline vapours, car exhaust, taxi cabs, little-kids-who-just-got-back-from-preschool disease vectors, responding to Piper on BABB, George W. Bush, chemtrails, alien abductions, zombies, and Steven Segal).
It's the hypocracy of touting a 'healthy' and 'pure' product that's intentionally (they could have decided to use a glass bottle) contaminated with toxic waste that gets me.

Hi Bozola,
Do have any feel for the economics of a Nalgene polycarbonate bottle over what is in use now for water and soft drinks? Harder to make? More "exotic" ingredients?

I think it can be quite toxic in large enough amounts. The hydrogen bonding, important in many biological activities, is adversely affected. Since water is reasonably acidic, proton transfer to such biomolecules as enzymes is a possibility. Just by putting a neutron on the Hydrogen, the electrostatic interaction betweeen the Hydrogen proton and a lone pair of electrons is somewhat shielded thus reducing H-bonding.
Polycarbonate contains an expensive precurser - Bisphenol A. Those of you who wear glasses may know this, Polycarbonate lenses are among the most expensive to buy. Very good impact resistance & filters out some uv radiation to boot.
Greg.

Aha!! So I'm not the only one who calls the little twerps Vectors.
I usually just get raised eyebrows and puzzled looks when I refer to them that way.
It's much easier than calling them "disease ridden vermin".
That usually elicits violence.

A little disease is good for the health of the population, though.

I can't spend $7000 on a GCMS (remember, exchange rate) so looks like that is out.
As for diesese vectors, thats mostly those who aren't immunisied and spread the disease to those too young to be immunised.
Sadly immunisation is being badmouthed by cranks who have no evidence of it being harmful.

As a membre of the military, I think I've had about every immunization shot ever invented. My shot record in 4 pages long and can't pronounce any of it. Some of those shots really hurt, and sometimes I'd be sick as a dog for a day or two. But I guess that beats dengue fever in the long run, huh?
There was a bit over on Skeptic News a month or so ago about immunizations in children. Some were claiming that they caused autism. This has been debunked, but I don't expect the media to let go of this any time soon. People don't tune in to hear "Whoops! We were wrong. Never mind."

Nonsense: rhinoviruses, for example. You can't immunize against colds. Further, being immunized to a disease doesn't mean you can't be a carrier. Little kids spread disease because they touch everything with hands that are in frequent contact with their bodily fluids. They are a horrific swealtering mass of pathogenic organisms.
