Sažetak
It is well known that heavy metals represent a big environmental problem in textile industry (waste water), as well as a potential danger to the human health when present in/on textile materials. Because heavy metals are often used as oxidizing agents, in metal complex dyes, dye stripping agents, fastness improvers, and finishers (water repellents, flame retardants, anti-fungal and odor-preventive agents) they act as sources of throughout the entire textile processing. Heavy metals can be very dangerous to the human population and their toxic effects are today subject of many scientific studies. Damages of organs, disorders in the respiratory tract and lung diseases, dysfunction of the heart, the blood and the blood producing organs, disorders in the nervous system, skin diseases, and abnormalities in fertility and pregnancy are reported. It was proven that accumulation of heavy metals in body tissues and their binding to enzymes disrupt the functioning of cells, which also leads to tumors or cancers. For this reason it is important to monitor heavy metals in and on textile materials. Today different standards are in use which prescribe the analysis of textile materials and indicate maximum permissible values, such as MST (Markenzeichen schadstoffgeprüfter Textilien), Öko Tex Standard (Internationale Gemeinschaft für Forschung und Prüfung auf dem Gebiet der Textilökologie), Clean fashion, Steilman, Commitextile, EC Approach, EPG (The European Product Guarantee) and Ecomarc Scheme. According to these regulations heavy metals should be extracted from textile materials and afterwards determined both qualitatively and quantitatively. Several analytical procedures for the determination of heavy metals were tested for their application on textile materials. The findings obtained were then compared. The advantages and disadvantages of TLC, UV-VIS, GF-AAS, ICP-OES and ICP-MS for the given purpose are reported. Recommendations for the sampling procedure as well as for the sample preparation steps for different natural and man-made textile materials are presented.
