Be careful, the cadmium content exceeds the standard by 7310 times, there are so many tricks in silver jewelry!

Have you ever felt or heard of something like this:

You bought a beautiful silver jewellery with great expectations, but when you put it on, you experienced redness, itching, allergies, and even the skin at the place where you wore it turned dark?

Many times, you think it is "your own problem". But the truth may be that there is something fishy about the silver jewelry you bought!

In order to help fans distinguish "real and fake silver jewelry", we have previously launched free identification activities for fans on platforms such as official accounts, Xiaohongshu, Weibo, and Zhihu.

In 2021, Laodabapingche.com identified 878 pieces of silver jewelry for fans, of which 45 were fake, accounting for 5.12%.

What is regrettable is that according to the data, some silver jewellery has a high lead content, with 42 pieces containing lead content exceeding 300mg/kg, accounting for 4.78%.

Some time ago, technicians even identified a fake silver jewelry with a cadmium content of 73.1%. In other words, the cadmium content exceeded the standard by 7310 times!

I was shocked. What is this concept? What is the standard of real silver jewelry? What are the hazards of excessive cadmium? What should I do if I want to identify silver jewelry? Let's read on.

Silver jewelry is one of the precious metals. According to the national standard for the purity and naming of precious metals, the purity range of silver and its alloys should be as follows:

However, some silver jewelry on the market not only does not meet the purity standards, but unscrupulous manufacturers also use nickel, copper and other alloy metals in the inner layer and counterfeit it by plating the surface with silver.

We have previously reported that there are very few people who are truly allergic to silver, and that many people's "allergies" are caused by these heavy metals.

For example, nickel is a heavy metal element that can easily cause skin contact allergies, while lead intake can also lead to cardiovascular disease and high blood pressure.

So, what will happen if cadmium exceeds the standard seriously?

First, let’s take a look at the total cadmium content test report of this adult silver jewelry sample.

The test result was 731088 mg/kg, with a cadmium content of 73.1%.

However, according to GB 28482-2012 "Regulations on the Limits of Harmful Elements in Jewelry", the cadmium content of adult jewelry should be less than or equal to 100 mg/kg.

OMG, what exactly is this cadmium that exceeds the standard by 7310 times?

Cadmium is a non-ferrous heavy metal element that is carcinogenic to humans and other animals. It is also cumulative, with a half-life in the human body of 16 to 30 years.

The United Nations Environment Programme (DNFP) and the International Commission on Heavy Metals in Occupational Hygiene have listed cadmium as the sixth toxic substance that is harmful to human health.

Silver jewelry is a favorite accessory for many women, such as necklaces, earrings, bracelets, anklets, etc. However, excessive cadmium is particularly unfriendly to women's health.

Many parents also like to dress their newborn babies in silver jewelry, hoping that their babies can grow up healthy and happy. However, if they encounter this kind of "fake silver jewelry", how uncomfortable the baby will be and how guilty the parents will feel!

We don’t want any of the above situations to happen to any family, woman or child.

I say this not to create anxiety or panic, but to hope that everyone will face up to this hidden but potentially harmful risk.
