is it safe to drink water thats been frozen in a plastic container?

I just watched a news special recently on nbc re: freezing water bottles.\n\nI found this article that I copied and pasted.  But I have also read on other websites that it does not.\n\n"DIOXINS Carcinogens cause cancer. Especially breast cancer. Don't freeze your plastic water bottles with water as this also releases dioxins in the plastic. Dr. Edward Fujimoto from Castle Hospital was on a TV program explaining this health hazard. He is the manager of the Wellness Program at the hospital. He was talking about dioxins and how bad they are for us. He said that we should not be heating our food in the microwave using plastic containers. This applies to foods that contain fat. He said that the combination of fat, high heat and plastics releases dioxins into the food and ultimately into the cells of the body. Dioxins are carcinogens and highly toxic to the cells of our bodies.\n\nThen I found this article from John Hopkins that says it does not\n\n\nBALTIMORE -- Johns Hopkins researchers have responded to an e-mail warning against freezing water bottles. A recent e-mail hoax claims Hopkins scientists warned people that freezing plastic bottles releases dioxins into the water. But the researchers say that's entirely false -- they said freezing plastic water bottles will not expose people to dangerous chemicals.\n\nResults | Disclaimer \n \nAccording to Dr. Rolf Halden, of the Johns Hopkins Bloomberg School of Public Health, freezing actually works against the release of chemicals and scientists are not even sure plastics contain dioxins. \nHowever, Halden does warn that another group of chemicals that are used to make plastic less brittle can be released if you place them in hot water or heat them in the microwave.\n\nBut Halden stresses that people should not be afraid of drinking water and that "you are more likely to suffer from the adverse effects of dehydration than from the miniscule amounts of chemical contaminants present in your water supply."\n\nHe also said people should be more concerned about the quality of the water they drink more than the bottle from which they drink it. Although people tend to assume bottled water is the safest route, Halden said city water is much more highly regulated and monitored for quality.

Same reason a water bottle will crack(water expands when frozen), the only difference is the carbonated drinks aren't completely frozen so it leaks everywhere.

you'll be fine. just don't spill your vodka into the sample. if you can manage to not do that, then rest assured your liver filtered all that stuff out before you peed into the cup.

Prevents it from boilig or freezing

i would assume it depends on the plastic.  But NaOH pellets are stored in HPDE (high density polyethylene) plastic containers.  So my thinking is if concentrated NaOH is stored in plastic than the liquid should also be able.

Excellent question. It is possible. I assume you mean the solid form of water (ice). It is theoretically possible. At this time finacially impossible. You would lose a percentage of the surface area of the ice by sublimation. How do you propose to freeze the water to begin with? How will you keep it frozen (remove absorbed heat energy)? Where will your source of water be? If you are taking water from Earth, how will you get it into space?

Pure water.  The ice will have to melt before it could boil.  Water doesn't go through sublimation

yes the glass would break because unlike any other liquid water expands when frozen therefore the glass would break regardless of how full it is

Just make sure the large amount you drink is not A COLD GLASS OF WATER. They are now saying that cold water causes what you've eaten to solidify! Warm water is now the way to go!

It will always depend on teh source of fresh water.\n\nContmination is a big factor in answering the harmful part of the question.\n\nRunning water is safer but not 100% safe.\n\nAs long as your using a clean and reused drinking bottle you should be fine on that end.

Yes there is.  If there is any lead in your pipes anywhere, it will leach into hot water to a much higher degree than it would in cold water. (Think of what happens to a tea bag in hot water as opposed to cold.)  Lead is very, very bad for your brain.  Also, if the pipes are plastic, plastic leaches more easily in heat as opposed to cold. (Manufacturers of plastic food wrap/containers tell you to NOT microwave food in plastic!) And, by the way, have you ever drained your water heater and seen what comes out of it?  Yuck!

As long as it is unopened it should be fine.  The only problem that could occur is is something got into the water, otherwise you would be fine.

yes,as long as you dont drink the water

It is true about the temperature and air of the water but these bottles were not meant to be used after opening and when the companies were asked they said it was unsafe to do so.\n\nThe plastic is decomposing and the more use the more it leeches out and becomes deformed.

Yes they can be harmful because plastic is porus and collects and retains bacteria. I don't think it's advisable to resume them. I mean hot? I'd almost have to be boiling hot and you'd have to boil the bottle inside and out. It's not really worth the trouble I don't think. But IDK maybe if you put scalding hot stuff in it, it may kill the bad stuff. Here is an article that may answer your question better than I could.

Yes it is safe to drink.  It is nasty tasting but not bad for you.  It has just been cleaned of all minerals and spirits that are in normal tap water.  Hospitals use it in humidifiers and respiratory machines.  So if it was bad the hospital wouldnt use the stuff.
