Evaluation Report on Aluminum Drinking Water Bottles: Report on Trace Substance Residues
Aluminum drinking water bottles are a popular alternative to disposable beverage bottles. However, the shells of some water bottles actually dissolve in beverages. The effect on the health of people is of concern. In the testing process, only one manufacturer did not produce such products. Metal ion precipitation problem.
In 1845, three well-equipped ships led by British explorer John Franklin left London to explore new sea routes. This is a mysterious and legendary trip to the northwest, but he and 128 of his accompanying crew members have not survived.
For more than 100 years, this unfortunate incident has led to people's various imaginations and speculations. The tragic and mysterious ending has been unpredictable. With the development of science and technology, it was not until 1985 that people unraveled the mystery of this adventure. The reason is "lead." The tins of canned food that Franklin carries with her are all sealed by "lead," and lead in cans contaminates the food. In just a few months, "lead" has chronically destroyed the health of all crew members. Although this problem has now been solved, the use of lead on cans has continued for a long time. Today, although there are no lead in the jars on the market, they have not completely avoided similar pollution problems.
In order to be accountable to consumers and clearly evaluate the safety of food containers, we tested the beer cans in 1996 when Brewery was discovered, which is considered to be a carcinogenic substance. It was coated on the inside of the jars. Composite material precipitated material. A year ago, it was because of the large amount of this substance found in canned fish that the product was banned from selling on the Swiss market.
Aluminum drinking water bottles are usually coated on the inside with a coating of synthetic material, but there are also manufacturers who have only anodized aluminum by covering the exposed metal aluminum with an artificial oxide film. Hikers, cyclists, climbers and students have chosen lightweight, shock-resistant metal aluminum water bottles as alternatives to disposable beverage bottles. Andre Keller, of MCTREK Leisure Equipment in Frankfurt, Germany, said: "These water bottles are much better than the synthetic plastic water bottles we used before, because synthetic plastic water bottles are not absolutely guaranteed to be leakproof, and drinking water has a plastic taste. Harmful to health?"
In order to find out if the metal aluminum will contaminate the beverage, or if the metal aluminum has an inner coating, whether the synthetic material inner coating in the water bottle has BADGE or other synthetic substances decomposes and precipitates. At the same time our laboratory also tested the water bottle coating, screen printing and caps containing PVC. PVC, namely polyvinyl chloride, is a plastic made from formaldehyde-containing resin material and is not environmentally friendly.
To this end, we chose to test the 10 water bottles used by SIGG Sieg and VAUDE brands that are the most used on the market. As a result of the test, BADGE was not detected in any of the 10 bottles tested, but in the 8 bottles with synthetic undercoats, 6 were found to contain bisphenol A (this substance has a stimulatory effect on the skin. It is also produced from synthetic materials.) The aluminum ion content of beverages in the other two water bottles without inner coating exceeded the drinking water regulations. Only the two test bottles of the most famous SIGG water bottles in Switzerland and Germany did not measure aluminum ion content. However, the PVC imprint on the SIGG Shige bottle hinders it from becoming the perfect product. (Note: The above question SIGG Sigg was completely resolved in 1998)
Prior to the measurement, we added a mixed drink of apple juice and carbonated mineral water to 10 water bottles. For the two water bottles that had too much aluminum ions, we denied its quality. VAUDE's large and small water bottles have exceeded the EU limit and the drinking water regulations of not more than 0.2 mg of aluminum ions per liter. The actual measurement result is 1.13 ml in the first bottle and 0.91 ml in the second bottle. "Maybe this "What's wrong with the anodic treatment of batches of products," explains Reno Fiska, head of the VAUDE company, "After proper anodizing, water bottles should be acid-resistant." However, the test results of the next two bottles are even higher than those of the previous two. In the apple juice and mineral water mixed drink, the aluminum ion content in our laboratory was 3.2 mg and 1.6 mg, respectively. Fiskar's companion Stephen Engels promised: "We will immediately analyze and improve the production process in order to comply with drinking water regulations."
Some people suspect that aluminum can cause Alzheimer's disease, but it has not been reliably confirmed. Dr. Luz Froley, secretary general of the Alzheimer's Foundation in Frankfurt, said: "As a risk factor, if we say that aluminum may have this effect, then , at least it can be said that its role is insignificant." He pointed out that the increase in brain aluminum content in Alzheimer's patients may be the result of measurement errors. Professor Herman Dieter of the Federal Agency for the Environment also holds the same view: "The relationship between aluminum and Alzheimer's has not been confirmed, and there is actually more evidence that there is no relationship between them."
In terms of the effects of aluminum on human health, scientists have a series of other viewpoints. New trials have shown that excessive aluminum ions in foods may cause arteriosclerosis and hinder the metabolism of the body's phosphate. Experiments on animals have shown that: Aluminum is a neurotoxin.
Even so, Dr. Alley of the Federal Association of Consumer Protection in Berlin still explained that "From the health point of view, the above aluminum content detected from apple juice and mineral mixed drinks is still negligible, and the drinking water regulations have a limit of It must not exceed the World Health Organization's daily intake of 1 mg per kilogram of body weight. A cyclist weighing 70 kilograms will need to drink 20 to 77 liters of water to drink if it uses a water bottle without an inner coating. Numerical value."
Dr. Luz Flori of the Alzheimer’s Fund Association disagreed with his view: “Aluminum is potentially dangerous to human health. Unnecessary intake should be avoided.†Al deposition during drinking can actually be Avoiding, according to the results of the test, the synthetic coating can prevent the dissolution of the metal into the drink, but the synthetic coating itself is also a problem. The LEFO organization in Allenburg has found that in most water bottles there is bisphenol A (a kind of In the case of synthetic material production, Dr. Ulin N. Lin, the product packaging expert for the organization, was not surprised to see that the test results showed that there was a material precipitate in the coating. In the process of producing synthetic materials, all chemical reaction processes have raw materials that do not react completely with each other. According to Jodo Kaiser, a chemical expert from LEFO, "There will always be some useless deposits."
Bisphenol A can irritate the skin, but scientists believe this substance is not as dangerous as BADGE. Experiments on animals show that it has no carcinogenic or genetically modified effects. The bisphenol A content in aluminum bottles will gradually decrease with the use of water bottles, and the excess synthetic material in the coating will eventually disappear completely. This is why the manufacturer always advises the customer to rinse the water bottle before each use. Our tester, Jodo Cather, thinks this is a very reasonable idea, but still thinks that this test result cannot be completely accepted. Because food and consumer goods regulations point out: Unless technically unavoidable, these substances should not be allowed to dissolve in food. The manufacturer, SIGG Sieg, proved that it is entirely possible to avoid deposits from synthetic coatings. When it comes to why it can be avoided, Rogge Krad, the head of SIGG's Siegel water bottle, explained that his company completely changed the production process two years ago and now uses a water-based interior coating.
In fact, other companies are also busy with other options in the inner coating of containers. Since 1996, we have learned that some substances such as BADGE and bisphenol A can be resolved from synthetic coatings. For example, the sales manager of the German cannery at Wick Fein explained: "We have been producing various kinds of food packaging containers for the food industry in Cuxhaven since April 1996. We have been experimenting with improved products in factories there. Coating material,"
For bottle caps, some improvements can also be made. Some caps are made of polyoxymethylene, although it can be made very precise. "However, this synthetic material contains formaldehyde," our technical adviser on Udlands The doctor explained: "Formaldehyde is a kind of material that may cause a variety of allergies, and it is suspected to be carcinogenic. If formaldehyde is in direct contact with liquids, it will dissolve slightly - and the water bottle cap is in direct contact with the drinks." BASF Spokesman Kelvinville demonstrated: "In our tests, polyformaldehyde could not resist 10% citric acid at temperatures between 60°C and 80°C." However, water bottles are not required to bear this burden in normal everyday use. risk. Because pure lemon juice has only 7% acidity, this means that you can use PET bottle caps to hold hot tea and lemon without any danger.
But SIGG Seeg is looking for another option without formaldehyde. The new material is planned to be adopted within 5 months. Because SIGG's caps can be purchased individually, it can be used to replace the bottle stoppers that have been sold in the market.
Dr. Dieter Udran said: "The laboratory also tested the outside of water bottles. Some water bottles have a PVC stamp, and one of them has a PVC adhesive. Although this ecologically harmful PVC material is rare, it is very Small amounts should also be avoided.†There is another reason why there should be no use of PVC in aluminum drinking water bottles. That is when aluminum and PVC are burned together, they release a large amount of dioxin, which is a cancer causing or causing Ternary heterocyclic hydrocarbons. (Note: The above question SIGG Sigg was completely resolved in 1998)
From an environmental point of view, I sincerely recommend aluminum bottles, because it is very durable, and SIGG's Rove Kress says: "As long as the coating is not damaged, they can use it all the time." Nature and Environmental Protection Association The person in charge, Olafur Band, also agreed to use aluminum drinking water bottles. He said: "If you can replace many disposable water bottles with one aluminum water bottle, it is very reasonable from an environmental point of view.
How long will the disposable cans and drinking bottles affect the environment? In this regard, we have been able to trace back to Franklin's expedition. Until now, those empty boxes and empty bottles have been abandoned on the islands of northern Canada.

It is also called a choking collar, which is recommended by almost all dog trainers. Its principle is that as soon as the dog leash is pulled, the collar will be temporarily tightened, which will make the dog`s neck feel oppressive, and at the same time this collar will make a jingle that dogs don`t like. This is an effective way to correct the dog's wrong behavior.
