With the arrival of summer, many women began to buy a variety of simulation jewelry. These styles are fashionable and inexpensive, and are popular among young ladies. At the same time, due to the lack of regulation of toxic and hazardous substances, the “jewelry disease†brought by simulated jewelry has received more and more attention. In addition, there are no names and product certificates for the simulation jewelry, and there are still no problems such as the component identification and the manufacturer name address. On May 1, 2013, the national mandatory standard GB 28480-2012 made a limited regulation on the harmful elements such as lead, cadmium and nickel in the jewelry, and the harmful substances in the simulated jewelry became a hot topic.
The simulated metal jewelry is mainly made of titanium steel, copper-zinc alloy or plastic materials. Generally, metals such as lead, nickel and cadmium are used for plating the jewelry to increase the color of the jewelry. With the improvement of processing technology and the increase of supervision, the problem of lead and cadmium exceeding the standard of simulated metal jewelry on the market is rare. The most problematic is the excessive metal nickel. Most of the silver-free metal jewelry is made of nickel-copper-zinc alloy, but the surface is plated with different colors. In summer, the temperature is high and sweating, which will accelerate the release rate of metallic nickel and cause symptoms such as contact dermatitis. If not treated in time, skin cells are prone to malignant lesions.
Experts remind consumers: First, we should try to purchase product certification, material name and manufacturer name and address, and other complete information on simulated metal jewelry. Second, carefully choose earrings and other puncture-like simulation accessories. Such accessories are sensitive to the reaction of harmful substances in the body due to their special wearing manner. The GB release of GB 28480-2012 stipulates that the nickel release amount of the puncture jewelry is 0.2 mg per square centimeter. The limit of other jewelry directly in contact with the skin is 0.5 mg per square centimeter. Therefore, consumers should try to buy puncture jewelry such as pure gold, silver and other precious metals or natural gemstones. The third is to buy necklaces, bracelets and other accessories that are in direct contact with the skin. Try to choose accessories that are too bright and have too bright appearance. In addition, in swimming, bathing or a lot of sweating, it is best not to wear close to the body, less contact with chemical products such as cosmetics or hand cream, consumers with allergic and scarred physique is best not to wear artificial metal jewelry.
