Determination of toxic metals in discarded Liquid Crystal Displays (LCDs)Determination of toxic metals in discarded Liquid Crystal Displays (LCDs) Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-162014enThis study focused on the determination of the toxic metal content of Liquid Crystal Displays (LCDs) present in various Waste Electrical and Electronic Equipment (WEEE). The main objective was the identification and quantification of toxic metals detected in LCD panels. An experimental procedure which involved dismantling, shredding, pulverization, digestion and chemical analysis was followed for the sorting, separation and analysis of LCD monitors from various electronic devices that are currently on the market. Nine selected devices were examined, originated from four different types of e-waste (WEEE); TVs, computers, mobile phones and tablets. Eleven metals were measured in all examined samples. In addition, concentration values of chromium (Cr), cadmium (Cd), lead (Pb) and mercury (Hg) were compared with the respective limits set by the RoHS 2002/95/EC Directive that was recently renewed by the 2012/19/EU recast. The comparison revealed that the examined toxic metals on LCD panels did not exceed the limits set by the European Union (EU). Furthermore, when results were compared to the TTLC regulatory limits it was revealed that in three samples As concentrations were higher than the limit. Finally, when the TCLP test was implemented the aforementioned samples did not exhibit proportionally elevated values in their leachates.http://creativecommons.org/licenses/by/4.0/Resources, Conservation and Recycling92108-115 Savvilotidou Vasiliki Σαββιλωτιδου Βασιλικη Chachladakis Ioannis Χαχλαδακης Ιωαννης Gidarakos Evaggelos Γιδαρακος Ευαγγελος Elsevier WEEE Waste LCDs Toxic metals Arsenic 2012/19/EU Directive
