1. The main components of chrome plating additives are fluoride, bromide, iodide, etc. ,
2. Danger:
It has irritating and burning effects on human adhesive molds and skin, and can cause injuries and contact dermatitis. These compounds enter the human body in the form of vapor or dust, which can cause perforation of the nasal septum, gastrointestinal disorders, decreased white blood cells, and lung lesions similar to asthma. Skin contact with chromium compounds can cause "chromic sores" that heal very slowly. When the concentration of chromic anhydride in the air reaches 0.15-0.31 mg/cubic meter, the nasal septum can be perforated. Chromium is a skin allergen and can cause allergic dermatitis or eczema, which has a long course and will not heal over time.
. The toxicity of chromium to the human body includes systemic poisoning, irritation to the skin and mucous membranes, and causes dermatitis, eczema, tracheitis, rhinitis and allergic reactions.
