CAPpings - Corrosion of metals over a long time can cause breakdown and loss of the dental implant as well as health problems for the patient

Metallic ions released as the result of corrosion of dental implants react with other components of the body, leading to sensitivity, inflammation, and, ultimately, autoimmune disease.

Know Galvanic Cell (Battery) set up in Saliva - "Oral Galvanism"

Corrosion of metals over a long time can cause breakdown and loss of the dental implant as well as health problems for the patient.

Titanium implants constantly release metal ions into the mouth. This chronic exposure can trigger hypersensitivity, inflammation and allergies, as well as autoimmune disease in people with high sensitivity. The metal implants can become part of a charged battery. All that is needed to make a battery is two or more different metals and a liquid medium (electrolyte) that can conduct electricity. Metal implants, fillings, crowns, partials, and orthodontic appliances provide the dissimilar metals, and saliva in the mouth serves as the electrolyte. This phenomenon, called “oral galvanism,” creates two major concerns.

First, the electrical currents increase the rate of corrosion (or dissolution) of metal-based dental restorations. Even precious metal alloys continuously release ions into the mouth due to corrosion, a process that gnaws away at the metal’s surface. These ions react with other components of the body, leading to sensitivity, inflammation, and, ultimately, autoimmune disease. Increasing the corrosion rate, therefore, increases the chance of developing immunologic or toxic reactions to the metals.

These electrical potentials, especially those developed by implants, set in a chronic, degenerative and inflamed section of the bone, can disturb local physiology and affect the body’s entire regulatory ability through osseous, lymphatic, immune, vascular, endocrine, autonomic nervous and meridian systems.

A second concern is that some individuals are very susceptible to these internal electrical currents. Dissimilar metals in the mouth can cause unexplained pain, nerve shocks, ulcerations and inflammation. Many people also experience a constant metallic or salty taste, a burning sensation in the mouth, and insomnia.

CAPpings: Corrosion causes contamination of drinking water with sewer leading to Gastroenteritis outbreak in Bangalore

Corrosion causes contamination of drinking water with sewer leading to Gastroenteritis outbreak in Bangalore

A day after 12 patients were admitted to a private hospital with suspected gastroenteritis (GE), health officials on Wednesday insisted the situation was “under control” even as four new cases were reported.

Of these four, two were admitted to K.C. General and two to a private hospital (Lakshmi Nursing Home) in Ramachandrapuram. According to K. Annamalai, Medical Director, Lakshmi Nursing Home, all the 12 patients admitted on Tuesday have been discharged. Two new cases were admitted Wednesday evening, while 11 others were treated as out-patients. The two patients have been put on fluids as they were suffering from dehydration.


R. Surendra, Bruhat Bangalore Mahanagara Palike's (BBMP) Deputy Health Officer (Gandhinagar), told The Hindu two patients were admitted to K.C. General Hospital Tuesday night and discharged on Wednesday. He attributed the rise in GE cases to drinking water being contaminated with sewage.

“The patients were mostly from the Okalipuram slum. The slum-dwellers have drawn illegal [water] connections and the underground drainage system is not sound. As the water pipeline is corroded, the chances of sewage mixing with drinking water are high.”

CAPpings - Corrosion annoys Coastal Homeowner

Corrosion annoys Coastal Homeowner - the coastal environment offered peace, serenity and a place to get away from it all - until corrosion, wind and water created a nightmare in vacation homeownership 

OWNING A home on the coast shouldn't be a lesson in dreams gone wrong.

For Wayne Higson, the coastal environment offered peace, serenity and a place to get away from it all - until corrosion, wind and water created a nightmare in vacation homeownership.

"People don't really know how bad things can get until they own a home in this type of environment," Higson said. "You realize there's no Yellow Brick Road to follow to get help."

Higson, 58, of Greenville, N.C., built his dream vacation home in Emerald Isle, N.C., and soon realized the standard construction materials were not faring well in the weather.

He got tired of replacing exterior lighting every few months, and major costs kept creeping up, including repairing the corroded air-conditioning unit.

CAPpings - Corrosion Awareness - Corrosion spoils canned foods

Cans or glass jars with metal lid can get rusted if not used properly.

Cans could even corrode, if food will chemically react with metal container.


All of us have used canned food once in our life time. Canned foods are the most prominently used packed food all over the world. We can see the canned food in each house hold. People use them because they are easy to be maintained & need less time to be cooked. Moreover they don't loose their natural taste as well. But to keep their taste & quality for long time certain care should be taken while using them. Moreover there are certain limits to how long food quality can be preserved. You must be asking why? It's because several factors limit the shelf-life of canned foods such as:-

Cans or glass jars with metal lid can get rusted if not used properly i.e. touched by wet hands or spoon & when rust will be deep enough, tiny holes open in the can or lid may let spoilage agents in & will spoil the food. That's why we should avoid water contact from can.

Cans could even corrode, if food will chemically react with metal container. Especially highly-acid food like canned tomatoes and fruit juices gets easily corroded. When kept or used for several years causes change in taste and texture. It eventually lowers down the nutritional food value also. So this type of food should not be kept for very long time in home.

Corrosion Awareness for Public - CAPpings Movement is now on Facebook

You know how much energy is available within the scientific community to resolve corrosion issues faced by Public. The situation in industries is totally different. It is driven by the investment capabilities of asset owners to do research and find solutions for complex problems. If the assets are owned by Public, who will extend "Helping" hands for finding answers? Public only. It is purely Public-Public collaboration to resolve our own issues. We need energy to alarm the community through human-powered transmission.

We can ping at this time. Most importantly, CAP is an eco-friendly Movement.

CAPpings - Consumers pay more money for water due to corrosion problems

Corrosion in water supply distribution systems is a very significant concern because it not only affects the aesthetic quality of the water but also it has an economic impact and poses adverse health implications. Corrosion by-products containing materials such as lead and cadmium have been associated with serious risks to the health of consumers of drinking water.

Article Source: National Service Center for Environmental Publications (NSCEP)

Consumers pay more money for water due to corrosion problems. Why?

1. Increased pumping costs due to corrosion products clogging the lines.
2. Holes in the pipes, which cause loss of water and water pressure.
3. Frequent replacement of pipes and fittings
4. Replacement of hot water heaters and washing machines.
5. Consumer complaints of colored water, stains and bad taste
6. Most importantly, your Medical Bill.

Corrosion of pipelines influences contamination of drinking water, a major concern for many Homemakers in Chennai

Tests show Chennai water full of toxins, germs

CHENNAI: Tap water in most parts of the city is full of disease-causing germs, toxic sediments and human and animal faeces. In places like Tondiarpet, Basin Bridge, Nungambakkam and Pulianthope, the water is so contaminated that drinking it straight from the tap could be lethal. Replying to an RTI petition, the Corporation of Chennai said it had conducted repeat tests on water samples in 2010-2011.

Corporation officials said leaky pipelines, overflowing sewage, open defecation and corroded pipelines have led to severe water contamination in the city. The average age of underground pipes is 50 years. Rust has gnawed holes in the pipes that snake through the city's filthy underbelly. Sewage and muck seep into the pipes and the disgusting, and deadly cocktail, is delivered to houses in the city. R Valarmathi, a homemaker residing at Pulianthope, said the water she gets at home often stinks. She stores boiled water, but her two children hate how it tastes. "I'm scared when I see them drinking water straight from the tap." Packaged water provides some people with a relatively safe option to tap water.

India - Corrosion Concern - Hazards of using rusted flatware

Query posted by a Home Maker in India:

We use Stainless Steel Flatware (Spoon, Forks and Knives) for eating while at home. I have been under the impression that by using SS flatware in Dishwasher the former shall be prone to rust. However I have been using the dishwasher since long to clean my flatware. of late I have noticed that many of my spoon forks and knives have rusted. I have confirmed and they are certainly rusted. not have found the pattern we use, we are reluctant to replace these flatware unless we find new flatware with the same pattern. hence my family members and I have been using this flatware for eating. the rust has appeared in places of the flatware which is directly in contact with the food we eat. this has raised fears in my mind that I might be poisoning myself when eating from such rusted flatware.

I would like to be informed whether eating out of such rusted flatware might poison me or lead to any health hazard. if it is so I shall refrain from using such flatware as I would not like to put a few lives at risk. this in mind I have contacted you with the confidence that you shall be of valuable help in this regard. looking forward to your prompt response.

Corrosion - Is it the subject of discussion by Corrosion Researchers and Practicing Engineers only?

Corrosion is considered to be a complex process involving many variables and causes. There is a misconception: Nothing is done about corrosion since this is a part of natural degradation phenomena. Considering the complexity involved in finding solutions for corrosion problems, common people have the feeling that this is the subject of research by field experts.

Corrosion Awareness for Public - What is corrosion?

Corrosion is the gradual destruction of material, usually metal, by chemical reaction with its environment. In the most common use of the word, this means electro-chemical oxidation of metals in reaction with an oxidant such as oxygen. Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal. Corrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term degradation is more common.
