Application of nano-level metal coated textiles are becoming more broad spectrum - socks, toothbrushes, shower curtains, tablecloths, detergents, creams, means to care for wounds, plasters, sanitary products, etc. - although the new material properties at the nano level is not fully investigated, especially the impact of the released very active nanoparticles/ions of heavy metals on the health of operators, users and the environment. At present, in studies of nanoparticles of heavy metals used biological methods - experiments with cells, microbes, embrio of fish, bacteria, etc. Rapidly growing range and volume of use creates a need to develop appropriate testing methods and devices for an in-depth analysis of their impact on humans and the environment with reduced time and lower costs. One of the way to obtain quantitative information about the level of pollution in the early stages of it developement, is testing a liquid with equipment of gas discharge visualization bioelectrography (GDV BEG). This article presents an assessment of the influence of metal ions released from the nano-level metal coatings of textiles in the manufacture and exploitation process. The article addresses the following issues - a selection of samples, development of optimal testing, a technology for processing and interpretation of data with special emphasis on the analysis of parametric studies of the image.
