Title: Estimation of urban POP and emerging SVOC levels employing Ligustrum lucidum leaves
Issue Date: 2019
Abstract: Many persistent organic pollutants (POPs) have been banned in many countries including Argentina after enforcing the Stockholm Convention in 2014, while other emerging semi-volatile organic contaminants (SVOCs) are considered to enter the list due to their known environmental persistence and toxicity. However, there is still very little information regarding the distribution of these chemicals in the environment in developing countries. To address this issue, we employed leaves of Ligustrum lucidum Ait. as a passive monitor to estimate urban levels of polychlorinated biphenyls, brominated flame retardants and hexachlorobenzene (PCBs, BFRs, and HCB, respectively) considering three different land use areas in Cordoba city (Argentina). We found higher PCB values in urban and industrial areas, which could be attributed to local emission sources as well as a long-range transport of lightweight compound. BFRs were more abundant in the urban areas indicating that their main emission source is the volatilization from polymeric materials. HCB, on the other hand, was equally distributed at the three sampling areas. Overall, POP and SVOC levels were similar or even lower than some other urban environments and even comparable with remote places elsewhere.
