People often wear metal necklaces, many of which are K-gold jewelry. In the production process, a small amount of other metals such as chromium, nickel and copper are mixed into these metals in proportion. When the weather is hot, human sweat increases, and the moisture in the sweat can dissolve a small amount of nickel sulfate on the surface of simulated jewelry, which will cause allergic reactions after skin absorption, thus inducing skin diseases.
Some people with allergies react more strongly. Some people are allergic because of the metal head on the belt and the metal frame on the glasses. The allergic symptoms of these people are manifested in the parts where jewelry comes into contact with the skin, such as ears, neck, wrists and fingers. Some people will have a systemic allergic reaction. First, the skin is red and swollen, and then small papules and blisters begin to appear, and the whole body itches and feels uncomfortable.
Zhang Likui, Standardization Technical Committee of China Jewelry and Jade Jewelry Industry Association, said that at present, there is no unified jewelry industry standard in China. There is no scientific definition of the material and function of jewelry. Generally speaking, the performance of pure gold, pure silver or jewelry is stable. When consumers choose jewelry, the most important thing is to compare materials and techniques, and try to choose pure gold or sterling silver jewelry. If you want to wear other jewelry, first of all, you should know whether your skin has allergic reactions according to your own physique, and try to avoid wearing jewelry that is most likely to cause dermatitis, such as gold-plated, silver-plated and nickel-plated. If you feel unwell, stop wearing it immediately and go to the hospital in time.
2. Pregnant women, patients with hypertension, bronchitis, diabetes and psoriasis can't wear gold, platinum and diamonds, and pharmaceutical factory employees are strictly prohibited from wearing gold and silver.
Gold is a heavy metal. In ancient times, there was a saying that "people swallow gold and die". The main reason why pregnant women and lying-in women can't wear gold ornaments is that it affects the fetus and young children. The light emitted by gold jewelry is particularly irritating to the baby's eyes, which causes the baby to cry more and sleep badly, which affects the development. Silver jewelry may contain too many harmful elements such as lead and chromium, which is more harmful to children if worn for a long time.
Psoriasis patients had better not choose jewelry with alloy. In addition to pure gold, there is a certain amount of chromium, nickel, copper and so on. Generally, it is added to various metal ornaments in the production process, and its composition is extremely complicated, so it is easy to hurt the skin when wearing such ornaments.
If pharmaceutical factory workers wear gold and silver, once they make mistakes, they may make mistakes in drugs, which will seriously endanger people's lives.
