Safety Warning: Dihydrogen Monoxide (DHMO)
Forwarded email warns of serious health hazards associated with the chemical substance dihydrogen monoxide, also known as DHMO.
Description: Email joke / Hoax
Circulating since: 1990
Status: True (nudge, wink!)
Email example contributed by S. Keeton, Apr. 16, 2001:
Dihydrogen monoxide is colorless, odorless, tasteless, and kills uncounted thousands of people every year. Most of these deaths are caused by accidental inhalation of DHMO, but the dangers of dihydrogen monoxide do not end there.
Prolonged exposure to its solid form causes severe tissue damage. Symptoms of DHMO ingestion can include excessive sweating and urination, and possibly a bloated feeling, nausea, vomiting and body electrolyte imbalance. For those who have become dependent, DHMO withdrawal means certain death.
· is also known as hydroxl acid, and is the major component of acid rain.
Contamination is reaching epidemic proportions!
Quantities of dihydrogen monoxide have been found in almost every stream, lake, and reservoir in America today. But the pollution is global, and the contaminant has even been found in Antarctic ice. DHMO has caused millions of dollars of property damage in the midwest, and recently California.
Despite the danger, dihydrogen monoxide is often used:
· as an industrial solvent and coolant.
Even after washing, produce remains contaminated by this chemical.
Companies dump waste DHMO into rivers and the ocean, and nothing can be done to stop them because this practice is still legal. The impact on wildlife is extreme, and we cannot afford to ignore it any longer!
The American government has refused to ban the production, distribution, or use of this damaging chemical due to its "importance to the economic health of this nation." In fact, the navy and other military organizations are conducting experiments with DHMO, and designing multi-billion dollar devices to control and utilize it during warfare situations. Hundreds of military research facilities receive tons of it through a highly sophisticated underground distribution network. Many store large quantities for later use.
Analysis: "DHMO" is a synonym for "H2O" -- the scientific name for water. Replace every instance of "DHMO" and "dihydrogen monoxide" in the message above with the word "water," and you'll get the joke (if you didn't already).
The DHMO warning is a parody of exaggerated health alerts of the type we find circulating on the Internet every day, warnings that spread needless fear by taking advantage of scientific ignorance and consumer gullibility. It's actually quite instructive, if taken as an exercise in critical thinking. By presenting a series of essentially true statements in a grossly misleading way, even something as harmless as water can be made to sound like a dire threat to human health and environmental safety.
The text itself dates back to 1988, two years before it was first posted on the Internet by one of its authors, a U.C. Santa Cruz student named Eric Lechner. Lechner and his cohorts subsequently created a tongue-in-cheek Coalition to Ban DHMO. Thankfully, the Coalition's efforts were, uh, somewhat less than successful.
