1, jewelry dermatitis.
Some women wearing rings and necklaces can cause contact dermatitis of the neck and fingers, with itchy skin, erythema, desquamation and papules, and even asthma or systemic urticaria in severe cases.
2. Local infection.
When piercing ear holes, tongue holes or nostrils, it may cause infection due to lax local disinfection or improper nursing afterwards, and it may also cause organ damage due to friction and hanging of jewelry, resulting in secondary infection.
3, causing deformity.
The most common is finger or toe ring deformity. Some people wear the ring for a long time, even if they don't take it off at night, it will cause local blood supply deficiency, cause tissue hyperplasia at the lower part of the ring or local persistent infection, and eventually lead to finger or toe deformity.
Extended data:
Four textures: Cooked gold is gold after smelting and purification of raw gold, which is generally high in purity and fine in density, and some of it can be directly used in industrial production.
Common are gold bars, nuggets, ingots, various ornaments, utensils, gold coins, industrial gold wires, sheets and plates.
Because of different uses, the required fineness is different, or because there is no purification equipment, only unpurified gold is melted, or the purity is not enough to form gold with different fineness. It is customary to divide mature gold into pure gold, red gold and colored gold according to its fineness.
Gold with a fairly high purity after purification is called pure gold, and gold generally refers to pure gold with a purity of over 99.6%.
1. Red gold and pure gold have similar meanings, but the standard of red gold varies with time and place. Gold with a purity of 99.6% sold in the international market is called red gold. Domestic red gold is generally between 99.2% and 99.6%.
