I am very allergic to nickel, and I have 3 tattoos. I had no problems with them. Go to a reliable, certified shop. Ask your artist about their ink, and what the ingredients are.
Skin reactions to jewelry are most commonly caused by a nickel allergy.
YES, only if you eat dairy before you put it on
Nickel allergy is one of the most frequent metal allergies and in some countries 1 in 3 women are affected. But nickel is mostly present in "cheap" jewellery and wedding bands more often contain silver, gold or platinum. Allergy to these metals is less common and has probably developed due to metal exposure through dental metal fillings such as amalgam (silver fillings) or gold crowns. If metal fillings are removed and replaced by metal-free fillings, the allergy can disappear and jewellery can be tolerated again (however this may take years). Unfortunately there is no real treatment for nickel allergy apart from completely removing the allergen (ie nickel). If your wedding band contains nickel then you could consider getting it rhodium plated - however this will wear off and need to be replated.
nickel and zinc chloride
Yes, there are implants available that are Nickel Free, Zimmer and Smith & Nephew both produce one.
Try to avoid anything with even a tiny bit of nickel in it... Also what helps is if you put clear nail polish on the inside of your rings, it helps prevent skin allergy.
By the color, obviously. NIckel plated flutes are slightly golden and well, silver plated, they have silver color.
It is allergy to nickel. No one knows the reasons (just like some people are very allergic to bee sting, and can die, while others are unaffected).
This is a single displacement reaction, also known as a replacement reaction or a substitution reaction. In this reaction, aluminum (Al) replaces nickel (Ni) in nickel(II) bromide (NiBr2) to form aluminum bromide (AlBr3) and nickel (Ni).
Nickel can cause skin irritation and allergic reactions in some people when it comes into contact with the skin, leading to redness, itching, and rashes. It is not recommended to have nickel on a necklace, especially if you have sensitive skin or a known nickel allergy. Opt for nickel-free jewelry to avoid potential skin reactions.
In a single replacement reaction, iron (Fe) can replace nickel (Ni) in nickel(II) chloride (NiCl₂) because iron is more reactive than nickel. The reaction can be represented as: [ \text{NiCl}_2 + \text{Fe} \rightarrow \text{FeCl}_2 + \text{Ni} ] This produces ferrous chloride (FeCl₂) and solid nickel (Ni) as products.
