“…There is a significant lack of current atmospheric PCB data in Africa, with the most recent studies still reporting concentrations from air sampling campaigns performed approximately 10 years ago. 28,29 At the time, PCB concentrations varied widely across the continent (∑PCB of 2−2000 pg/m 3 ). 9,28−31 Atmospheric concentrations at MONET sites as of 2019 fall at the lower end of those in these previous studies, consistent with the decreasing trends over the past 10 years.…”

The Global Monitoring Plan of the Stockholm Convention on Persistent Organic Pollutants (POPs) was established to generate long-term data necessary for evaluating the effectiveness of regulatory measures at a global scale. After a decade of passive air monitoring (2008−2019), MONET is the first network to produce sufficient data for the analysis of longterm temporal trends of POPs in the African atmosphere.

“…Although PBDEs and NFRs were extensively investigated in the indoor dust and the ambient air worldwide, only few studies investigated their concentrations in the indoor dust (Abdallah and Covaci, 2014;Hassan and Shoeib, 2015) and ambient air (Arinaitwe et al, 2014;Pozo et al, 2009) collected from Africa. Additionally, none of the studies investigated their levels in the elevated fine dust (EFD), outdoor dust and/or their gaseous levels in the indoor and outdoor environments.…”

There is scant information on the presence of the polybrominated diphenyl ethers (PBDEs) and other alternative flame-retardants (NFRs) in Africa. Hence, to investigate their levels, sources, and human exposure scenarios, elevated fine dust (EFD) samples from apartments (n = 12), working places (n = 9) and cars (n = 12), floor dust (FD) samples (n = 5) and outdoor dust samples (n = 21) were collected from Alexandria, Egypt, during 2014. Gaseous concentrations were estimated using low density polyethylene sheets (n = 33 and 21 for indoor and outdoor sites, respectively). Indoor gaseous and dust PBDE (7.0-300 pg/m; 4.0-770 ng/g), and NFR (0.40-48 pg/m; 0.50-8.5 ng/g) concentrations were significantly higher (p = 0.004-0.02) than outdoor concentrations (PBDEs: 3.0-41 pg/m, 1.5-195 ng/g; NFRs: 0.20-13 pg/m, 0.50-4.0 ng/g). Median PBDE concentration in cars (210 ng/g) was higher than in apartments and working places (130  ng/g respectively). PBDE concentrations in FD were 7.0-14-folds lower than EFD concentrations. Outdoor PBDE concentrations were significantly higher (p < 0.01) at residential-industrial places with older buildings. All samples were dominated by BDE-47 and 99. HBB, BTBPE and DDC-CO were the most abundant NFRs in EFD samples. Profiles of PBDE and NFR in FD closely matched those of outdoor dust, indicating a possible carryover from the outdoor environment. Although factors such as number of electronics, construction year and floor type significantly correlated with the majority of PBDE congeners and some NFRs in apartments and working places, sources were not clearly identified for NFRs. Significant log-linear relationships were obtained between theoretical and calculated dust-air partitioning coefficients for all samples indicating an equilibrium state between dust and vapor. Low possibility of occurrence of adverse health effects was concluded, with the inhalation pathway (for adults) and dust ingestion (for children) acting as the most important exposure routes.

“…A comparison with PCBs environmental contamination in various sites around the world is presented in Table 5. Total PCBs concentrations in the ambient air and particulate phase reported for Atlantic Ocean, India coastal area, East Africa, Turkey, France, Pohang (Korea), Karachi and Lahore, Panjab (Pakistan), Kanpur (India), London, and Yokohama (Japan) were found to be in the range: 4-220, 216-1,077, 65.6-244 pg m −3 , 52-293 ng m −3 , 10-270, 15-166, 48-61, 34-389, 254-432, 1,000-2,000 and 62-250 pg m −3 , respectively (Arinaitwe et al 2018;Goel et al 2016;Sakin and Tasdemir 2016;Nasir et al 2014;Syed et al 2013;Baek et al 2010;Gioia et al 2008;Zhang et al 2008;Blanchard et al 2006;Kim and Masunaga 2005). Hence, the values reported herein would be among the highest (comparable to those from India and Pakistan).…”

Persistent organic pollutants, such as polychlorinated biphenyls (PCBs), pose a serious risk for human health and the environment. 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 to particulate matter), 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 sediment 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 (PM 10), 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.
