Is titanium harmful to the body?

No substance in this world is absolutely harmless. Many substances are not harmful to the human body in themselves, but when the amount of the substance in the human body reaches the amount that the body can bear, it will cause some harm to the body. For example, titanium is the only metal among all metals that will not cause an immune response when combined with the human body. Now let’s talk about whether titanium is harmful to the body.

1. Health Hazards

Routes of entry: Inhalation, ingestion.

Health hazards: Irritating to the upper respiratory tract after inhalation, causing coughing, chest tightness or pain.

2. Toxicological Information and Environmental Behavior

Hazardous characteristics: Titanium metal dust is explosive and will burn and explode when exposed to heat, open flame or chemical reactions. Its powder is highly chemically active and can spontaneously combust in the air. Metal titanium can burn not only in air, but also in carbon dioxide or nitrogen. It easily combines with halogens, oxygen, sulfur and nitrogen at high temperatures.

3. First aid measures

Skin contact: Take off contaminated clothing and rinse skin thoroughly with soap and water.

Eye contact: Lift eyelids and rinse with running water or saline. Seek medical attention.

Inhalation: Move quickly away from the scene to fresh air. Keep the airways open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.

Ingestion: Drink plenty of warm water, induce vomiting, and seek medical attention.

4. Utilization of Titanium

Titanium is biophilic. In the human body, it is resistant to corrosion from secretions and is non-toxic, making it adaptable to any sterilization method. Therefore, it is widely used in the manufacture of medical devices, artificial hip joints, knee joints, shoulder joints, rib joints, skulls, active heart valves, and bone fixation clamps. When new muscle fiber rings are wrapped around these "titanium bones", these titanium bones begin to maintain the normal activities of the human body.

Titanium is widely distributed in the human body, with the content in a normal human body not exceeding 15 mg per 70 kg of body weight, and its role is still unclear. However, it has been confirmed that titanium can stimulate phagocytes and enhance immunity.
