Rhodium together with ruthenium, palladium, osmium, iridium and platinum form a group of elements referred to as the Platinum Group (PGM) metals. Rhodium is a shiny, white-silver metal and has a higher melting point and lower density than platinum. It has high reflectivity and is tough and durable. Rhodium remains unaffected by air and water and is insoluble in most acids.
Rhodium is mostly used in catalytic converters for cars. The main use of the metal is in platinum and iridium alloys, giving improved resistance to high temperatures and resistance to oxidation. These alloys are used in furnaces, thermoelectric elements and high temperature cables, in aircraft, in jewelry and as a catalyst in a number of industrial processes.
Impact of rhodium on human health
Most people do not come into contact with rhodium. All rhodium compounds should be considered as highly toxic and carcinogenic. The compounds of rhodium "stain" the skin very strongly. Rhodium can be absorbed by the body through inhalation. The health effects of exposure to rhodium have not been fully investigated.
How can one determine if one has been exposed to rhodium?
We can measure rhodium levels in blood and most biological materials.
Determination of metals is done by ICP-MS (Inductively Coupled Plasma Mass Spectrometry, Inductively Coupled Argon Plasma Mass Spectrometry), a method that enables the simultaneous detection of many metals. Its sensitivity and accuracy are significantly better than conventional atomic absorption, with the ability to measure metals at concentrations up to 1 in 1015 (1 in 1 quadrillion, ppq)!
Laboratory test results are the most important parameter for the diagnosis and monitoring of all pathological conditions. 70%-80% of diagnostic decisions are based on laboratory tests. Correct interpretation of laboratory results allows a doctor to distinguish "healthy" from "diseased".
Laboratory test results should not be interpreted from the numerical result of a single analysis. Test results should be interpreted in relation to each individual case and family history, clinical findings and the results of other laboratory tests and information. Your personal physician should explain the importance of your test results.
At Diagnostiki Athinon we answer any questions you may have about the test you perform in our laboratory and we contact your doctor to get the best possible medical care.
