Nickel allergy and allergies to mercury and chromium have long been recognised; gold, palladium, and cobalt have gotten attention more recently. [2] [3] There is often cross-sensitization, where a person allergic to one metal may become allergic to another, but monosensitization, reacting to just one metal, is also possible. [4]
Metal fume fever, also known as brass founders' ague, brass shakes, [1] zinc shakes, galvie flu, galvo poisoning, metal dust fever, welding shivers, or Monday morning fever, [2] is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (Al 2 O 3), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are ...
Contact with skin is dangerous and adequate ventilation should be provided when melting this metal. [2] Many thallium compounds are highly soluble in water and are readily absorbed through the skin. [3] Exposure to them should not exceed 0.1 mg per m 2 of skin in an 8 hour time-weighted average (40-hour working week).
Additionally, radium phosphate, radium oxalate, and radium sulfite are probably also insoluble, as they coprecipitate with the corresponding insoluble barium salts. [5] The great insolubility of radium sulfate (at 20 °C, only 2.1 mg will dissolve in 1 kg of water) means that it is one of the less biologically dangerous radium compounds. [6]
Food allergies are on the rise. Here are some of the most common and harmful misconceptions about food allergies, according to allergists. These common myths about food allergies can have ...
The rash appears immediately in irritant contact dermatitis; in allergic contact dermatitis, the rash sometimes does not appear until 24–72 hours after exposure to the allergen. Blisters or wheals: Blisters , wheals (welts), and urticaria (hives) often form in a pattern where skin was directly exposed to the allergen or irritant.
The rash can appear as acute, subacute, or chronic eczema-like skin patches, primarily at the site of contact with the nickel (e.g., earlobe from nickel earrings). From the time of exposure, the rash usually appears within 12–120 hours and can last for 3–4 weeks or for the continued duration of nickel contact/exposure. [9]
Radiendocrinator, designed to be held on the skin over endocrine glands. One jockstrap accessory enabled treatment of the testicles. [12] [13] Uranium sand houses, where patients would sit on benches in a round room that had a floor composed of mildly radioactive sand (usually beach sand with crushed minerals like carnotite). These were popular ...
