In this study, PCBs contamination and sources of ambient air, road dust, and sediments in the most polluted city in India, Raipur, has been measured over the period 2008–2015. The seasonal variations of particulate matter (PM), elemental carbon (EC), organic carbon (OC), and carbonate carbon (CC) were studied, and maximum concentrations were detected in the December–January period each year. Total PCBs concentrations in the ambient air (associated with PM), road dust, and sediments samples during 2008 were in the 186–645 pg m−3, 102–537, and 241–538 ng g−1 range, respectively. 2-chlorobiphenyl (PCB-1) and 4-chlorobiphenyl (PCB-3) were the dominant chemical compounds identified. A substantial vertical migration of the PCBs in the sediments was observed. Concentration variations (spatial and temporal), correlations, and sources of PCB are discussed. In particular, an average increment rate of 6.2%, 4.9%, and 5.4% of PCBs concentration in the particulate matter (PM10), road dust, and sediments, respectively, was observed over the 2008–2015 period. The reported data points to India's low degree of accomplishment of the Stockholm Convention's requirement to phase out the use of PCBs in equipment by 2025 and ensure elimination of PCBs by 2028. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.415 2021 Chemical Engineering (miscellaneous) 2021 Q2 Environmental Chemistry 2021 Q2 Water Science and Technology 2021 Q2 Waste Management and Disposal 2021 Q2 Geotechnical Engineering and Engineering Geology 2021 Q2 2.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion Kumar Sahu, Yamar Patel, Khageshwar Singh Sharma, Saroj Hung, Chin-Chang Martín Ramos, Pablo Universidad de Zaragoza (orcid)0000-0003-2713-2786 Yurdakul, Sema 5011 500 Universidad de Zaragoza Dpto.
