Always bear in mind that tungsten is a metallic element extracted from scheelite or wolframite ores. It has the highest melting point of any metal and considered strong which makes it suitable for high-temperature structural materials.
Tungsten is utilized as one of the metals in various alloys or combination of metals such as tungsten-nickel and tungsten-carbide. These and other alloys are utilized to produce high-density filaments, electrodes and wire as well as jewelry valued for durability. Even though allergies or sensitivities are considered rare, there are reported cases.
What happens during an allergy to tungsten?
An allergic reaction occurs once the body reacts to a substance that the immune system identifies as a threat. As a defense mechanism, the immune system generates antibodies that fight off the perceived threat.
Always bear in mind that these antibodies known as immunoglobulin E antibodies (IgE) are specific to a certain allergen such as tungsten. A severe reaction can trigger a life-threatening reaction known as anaphylaxis which involves difficulty breathing, severe swelling and an abrupt drop in the blood pressure that can cause the individual to faint or go into a state of shock.
What are the allergy symptoms?
The IgE antibodies travel to the cells all over the body and trigger symptoms such as the following:
- Eczema
- Hives
- Runny nose
- Itchiness
- Sneezing episodes
- Asthma attack
When it comes to contact dermatitis, it involves a localized area of itchy skin and reddening that can progress to patches of scaly, dry skin. In severe cases, the skin can weep and blister.
Contact dermatitis due to jewelry that contains the element is not considered as an allergy to the metal. Take note that nickel allergy from tungsten-nickel allergy is the most prevalent cause of contact dermatitis from metal jewelry.
Even though rare, individuals in the metal industry especially those who are readily and constantly exposed to the metal dust can eventually end up with allergy.
Considerations to bear in mind
Always bear in mind that tungsten is one of the metals that are capable of triggering an allergic reaction especially skin irritation. When it comes to tungsten allergy, it is considered uncommon and more likely due to another metal that has been alloyed with tungsten.
If an individual is suspected to have an allergy to the metal, a doctor should be consulted especially if there are symptoms such as breathing issues, hives or facial swelling after being exposed.
