analysis of traces of product shots
Quality Analysis of Background Microparticles Characteristic of the Product Shot |
The paper deals with the content of chemical elements in the background, typical for product shots. The propagation problems of those elements and particles in the city environment were investigated. The typical elements and particles only for product shots were defined. Methodology of the study. Samples were taken at different sites and with different terrain surfaces. Samples were collected only in a solid form. Collection sites related to the frequency of finding the people around them and the probability of detection of substances similar shot products. The study was conducted by electron microscopy. Experimental part. Morphology images and chemical elemental composition of collected samples were obtained. It was found possible to detect product shots by: a) the difference in the qualitative composition of chemical elements shot and ambient background; b) in the absence of background particles from a circular shape having a certain size and the elemental composition of the characteristic shot. Discussion of the results. There was a dependence of the content of the background space Sampling. In this regard, the necessity of withdrawal of samples for studies not only the scene, but also environmental accident situation. Appearance and chemical composition of the particles typical for shot products were determined. |
