2. Dihydrogen Monoxide (DHMO) is a colorless and odorless chemical compound, also referred to by some as Hydric acid. Its basis is the highly reactive hydroxyl radical, a species shown to mutate DNA, denature proteins, disrupt cell membranes, and chemically alter critical neurotransmitters. The atomic components of DHMO are found in a number of caustic, explosive and poisonous compounds such as Sulfuric Acid, Nitroglycerine and Ethyl Alcohol.

3. Dihydrogen monoxide (also known as has no color, odor, or taste, but it kills thousands of people every year. Many people die from inhaling DHMO by accident, but the dangers do not end there. Exposure of the skin to solid DHMO can cause serious damage. If too much DHMO is swallowed, it can cause symptoms such as sweating, nausea, vomiting, and an electrolyte imbalance in the body.

4. What are some of the dangers associated with DHMO? Death due to accidental inhalation of DHMO, even in small quantities. Prolonged exposure to solid DHMO causes severe tissue damage. Excessive ingestion produces a number of unpleasant though not typically life- threatening side-effects. DHMO is a major component of acid rain. DHMO can cause severe burns. Leads to corrosion and rust of many metals. Contamination of electrical systems often causes short-circuits. Exposure decreases effectiveness of automobile brakes. Found in biopsies of pre-cancerous tumors and lesions. Thermal variations in DHMO are a suspected contributor to the El Nino weather effect. Is a major component in acid rain.

5. Despite the known dangers of DMHO, it continues to be used daily by industry, government, and even in private homes! as an industrial solvent and coolant. in nuclear power plants. in the production of Styrofoam. in biological and chemical weapons manufacture. in the development of genetically engineering crops and animals. as a fire suppressant and retardant. as a major ingredient in many household cleaners. as a byproduct of hydrocarbon combustion in furnaces and air conditioning compressor operation. in DAYCARE CENTERS, purportedly for sanitary purposes. in the distribution of pesticides. Even after washing, produce remains contaminated by this chemical.

8. Drinking water: Consumer Product or Public Utility? Every year millions of Americans drink bottled water instead of tap water. Bottled water sales have skyrocketed in the past 20 years. Why do people drink bottled water?

9. Unclear Terms One major difference between bottled and tap water is tap water has been chlorinated. Until 1993 water was labeled “spring”, “artesian”, “well”, ”distilled”, or “purified” without clear standards. Basically if 10% of the water came from that source, they could label it.

10. Could you distinguish bottled spring water, tap water, and store-bought distilled water? Distilled water-Water is heated to boiling. Water vapor is collected and turns back into liquid when cooled. The dissolved solvents and most contaminates do not vaporize and are left. Spring Water- water is obtained from an underground source that flows naturally beneath the earths surface
