Highlights

PM10 and some elements in PM10 were measured in a WEEE recycling factory in Greece.
8 h PM10 were lower than international standards but increased during working hours.
Some elements were enriched in PM10 indicating sources other than dust resuspension.
PCA for some elements enabled distinction between CRTs and other WEEE.
Risk assessment for some metals of toxicological concern shows non-acceptable risk.


Abstract

Processing of Waste of Electrical and Electronic Equipment (WEEE) causes serious environmental problems, especially when WEEE is processed in uncontrolled conditions. WEEE recycling under controlled conditions, consists of the following major steps: disassembly, upgrading and refining. Disassembly is usually done manually and, at this stage, certain components [cases, external cables, cathode ray tubes (CRTs), printed circuit boards (PCBs), batteries etc.] are separated. This activity releases coarse and fine particles into the atmosphere which may also contain additional noxious substances. The current study determines the concentration of indoor PM10 in a WEEE dismantling and temporary storage plant in Greece, based on a short-term sampling campaign. Elemental concentrations in PM10 have also been determined. Results show that the indoor PM10 concentration in the disassembly area did not exceed the time – weighted average (TWA) for total particles set by Greek legislation or the 8-h TWA for total particles set by Occupational Safety and Health Administration (OSHA). Nevertheless, these concentrations were higher than those measured in the ambient air of Greek cities. Regarding the measured elements, Zn, As, Br, Pb and Cd were quite enriched in PM10 indicating significant indoor sources. Factor analysis for elements of possible anthropogenic origin showed clear distinction between cathode ray tubes (CRT) and other possible sources. Finally, risk assessment for metals of toxicological concern showed non-negligible lifetime risk for 8h-workers. This is the first report of WEEE indoor air pollution in Greece and on the associated origins and effects.
