Abstract

The immense plastic bags (PBs) consumption is the potential threat for environment and public health due to discharging toxic pollutants (i.e., metals and metalloids) throughout its entire life cycle. The purpose of the study was to investigate the heavy metal (HM) contents in PE, HDPE, LDPE and PVC bags with several colors and applications. The HM contents in the PB were analyzed by ICP-OES after acid digestion. Results demonstrated that the HM contents in PB notably disagreed based on the used polymer types, colors and applications. The highest contents of Pb, Cr, Cd, As, Cu and Zn were 66, 75, 16, 28, 96 and 154 in mg/kg unit, respectively in PE bags; 71, 74, 34, 39, 430 and 212 in mg/kg unit, respectively in HDPE bags; 12, 74, 23, 43, 158 and 54 in mg/kg unit, respectively in LDPE bags; and 16, 23, 474, 12, 45 and 90 in mg/kg unit, respectively in PVC bags. Furthermore, 12 out of 36 PB samples were noticed to violate the standards (ISO 8124-3) in terms of Pb, Cr, Cd and As contents. So there is the potentiality of HM and metalloid pollution from discarded PB during treatment, recycling and disposal.
