Whether zinc alloy is toxic or not is related to the type and quality of the alloy. Zinc alloy is an alloy composed of zinc based on the addition of other elements, common alloy elements are aluminum, copper, magnesium, cadmium, lead, titanium and so on. Zinc alloys have different effects on the human body. 1, zinc alloy jewelry: good quality zinc alloy jewelry does not affect people with sensitive skin; people with sensitive skin may develop rashes, itchy skin and other allergic symptoms after wearing it. 2, zinc alloy tableware: zinc alloy tableware of good quality is very hard and corrosion-resistant, which has little effect on human health. Poor quality tableware by die-casting after electroplating antique copper, with a period of time, the plating layer will fall off, such tableware is harmful to the human body. And if the tableware contains too much lead, it will have an effect on all systems of human body. For adults, it will affect the blood system to produce anemia; affect the nervous system to produce weakness, dreaminess, dizziness, headache and other symptoms; affect the digestive system to produce abdominal pain, bloating, nausea, vomiting and so on; affect the circulatory system to produce chest tightness, palpitation, shortness of breath, tachycardia and so on. For children, there can be symptoms such as inattention, hyperactivity and impulsivity, and there may also be language and learning disorders; 3. Industrial zinc alloys: Zinc alloys produce dust during processing, which is hazardous to human health when working in such high concentrations for a long time. Zinc enters the body through the respiratory tract, and the inhaled zinc forms zinc oxide fumes at high temperatures can cause metal fume fever, which can cause symptoms such as metallic taste in the mouth, thirst, chest tightness, dry cough, headache, high fever, chills, etc. Moreover, the dust is irritating to the eyes and irritating to the skin with long-term repeated exposure.
