Health experts are warning of the dangers of consuming silver, a metal that has been associated with allergies and asthma in many countries.
The National Silver Council released its annual Silver Survey, a survey of the US silver market, which found the industry’s consumption of silver has grown from 9.4 million metric tons in 2000 to more than 20 million metric pounds today.
“Silver is the most popular precious metal in the United States,” said Dr. Matthew Paretta, chief of the National Silver Program at the National Institute of Allergy and Infectious Diseases.
“It’s used in so many things that it’s hard to think about, so there’s a concern.
It’s not a new problem.
It has been around for a long time, and it’s not going away.”
Silver, the silver-containing compound found in many metals, is a by-product of manufacturing and is not a component of jewelry.
Silver allergies are a problem in some countries, such as Russia, China and India, where the metal is used as a decorative metal and has been blamed for causing an increased risk of allergy and asthma.
Silver is used in jewelry and toothpaste, and in some consumer products.
“Silver allergies in the U.S. are becoming more common,” said Paretti.
“We’re not sure how much of an impact silver is having in the US, but we do know it’s a problem that’s getting worse.”
A 2015 study found silver allergy rates in the states rose by 15% between 2010 and 2013.
A 2013 study by the American Heart Association found that more than one-third of adults reported symptoms of an allergy to silver.
In a 2015 study, the FDA approved an inhaler that contains 1,200 milligrams of silver in the first two minutes.
The FDA also approved a nasal spray that contains up to 2,000 milligram silver daily.
A 2012 study by Cornell University found that when the inhaler was given to a patient with a severe allergic reaction to silver, symptoms improved over three weeks.
More recently, a 2013 study found that people with an allergy could experience a decrease in silver levels in their blood if they were given the nasal spray and inhaler.
The FDA said it would not approve an inhalers for people with severe allergies and those who have had a history of anaphylaxis to silver for any time within the last five years.
