Abstract: | Objective Explore the consequences of Scanning Electron Microscopy/ Energy Disperse X -ray Assay ( SEM/EDX) and Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) in inducing the metal injury implements. Methods Examined metal particles in 5 wounds made on the skin of little pigs respectively using Zn - Ni - coated spanners, Cu - coated pipes and carbon metal kitchen knife by SEM/EDX . 5 samples from the body and blade were analysised separately in the contents and varieties of elements by PSC. Result In the wounds by Zn - Ni - coated spanners, Cu - coated pipes,the particles only contained Zn,Ni or Cu, Zn, no other elements. In the wounds by carbon metal kitchen knives, the particles containing Fe, Cr, Si or Fe, Mn, Si were found. Except number 3 for non - coated kitchen implements , the differences of contents of elements between the body and blade were not significant, and the significant differences of contents of elements exited in Cr, Mn, Si, Cu, Mo, among the stainless kitchen knifes, Mn, Si among the carbon metal kitchen knives and for the blade of No. 3 knife, RSD were significant different in Mn,Si, Mo,Ti,S,P,Ni (P<0. 001). Conclusion Using EDX to examine the particles in wounds can induce the varieties of metal injury implements, and we can still induce the different implements in the same class by ICP - AES. |
