The paper addresses the issue of the detrimental elements that may occur in the metallic materials at trace level. The reliability of a metallic implant critical depends on its detrimental elements content. The ISO 10993-18:2020 addresses prerequisite for biological risk evaluation, but ISO 5832-1/2016 refers only to the main chemical composition that ensures the inertness of the implant in a tissue environment whilst the problem of detrimental element is missed. The leakage of detrimental elements as Al, Cd, Co, Hg and Pb into surrounding tissues is a potential risk for the patient. Therefore, this issue is highlighted in the paper and an adequate solution is proposed to estimate the content of detrimental elements into an AISI 316L biomaterial. Thus, the spark discharge in argon optical emission spectrometry (SDAR-OES) is proved to be an effective solution for the bulk concentration measurement of elemental constituents and the detrimental elements occurring into AISI 316L sample using. The main objects of this paper are: to enhance the measurement capability of the SDAR-OES method as to be use at least as the primary step for checking the contents of the detrimental elements into the candidate 316L biomaterial and also to argue for including the SDAR-OES method among the methods recommended by the ISO 10993-18 for measuring the chemical composition of the metallic biomaterials as AAS, ICP, MS. The novelties addressed are the method and technique used for estimating the detrimental elemental contents and providing facts for improving the chemical conformity requirements of the 316L.
