“…It is interesting to note that despite the prevalence of PCB‐180 in settled dust samples, it appeared to be depleted in Durban air (Batterman et al., ). The generally high prevalence of PCB‐180 and PCB‐153 in this study is akin to high levels of these congeners in wild bird eggs reported recently in South Africa (Quinn et al., ), and in fish tissues quantified as Aroclor 1254 in the Isipingo Estuary (Grobler et al., ).…”

Polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) were measured in indoor dust of three microenvironments in Durban, South Africa. The sum of eight PBDEs and three PCBs were quantified by gas chromatography with mass spectral detection. The mean concentrations of ∑n = 8 PBDEs and ∑n = 3 PCBs in 10 homes, 11 offices, and 13 university students' computer laboratories were 1710, 1520, and 818 ng/g, and 891, 923, and 1880 ng/g for PBDEs and PCBs, respectively. The concentration of PCBs found in homes was independent (P = 0.0625) of building construction year. Similarly, no relationship was observed between PCB concentrations and floor type. The concentrations of PBDEs correlated (r = 0.60) with PCB concentrations in homes, thus assuming similar sources. The elevated concentrations of PBDEs and PCBs may have significant implications for human exposure.

“…Previous studies have shown a higher prevalence of PCB153 and 180 in human breast milk from South Africa (Darnerud et al 2011). Similarly, PCB 153 and 180 were two of the three dominant congeners reported in wild bird eggs in South Africa (Quinn et al 2013), hence the need to monitor these two congeners in the indoor environment. Also, it is assumed that levels of PCBs that are skewed to higher chlorinated PCB congeners are linked to historic applications, whereas the presence of the lower chlorinated PCB congeners are more likely from recent or current releases (Quinn et al 2013), hence the choice of PCB 28 to be monitored indoors.…”

Workplace exposure to persistent organic pollutants is a concern for human health. This study examined the presence of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) in the indoor dust from two major e-waste recycling sites and a university electronic equipment repair workshop in Durban, South Africa, in order to evaluate the implication of dust for occupational exposure. The mean ∑(n = 8)PBDEs and ∑(n = 3)PCBs were 20,094 and 235 ng g(-1), respectively. The levels of PBDEs and PCBs obtained in one of the recycling sites (123-27,530 and 161-593 ng g(-1)) were significantly higher than the levels obtained (91-7686 and

“…The prevalence of high levels of PCBs 138 and 153 detected in the present study is in keeping with other findings reflecting the high persistence among the indicator PCB congeners commonly present in various sample matrices (Carro et al, 2000;EFSA, 2010). The higher congeners were generally more prevalent and it is well known that the biodegradability of PCBs decreases as the number of chlorine atoms increases (Correa et al, 2010;Quinn et al, 2013;Zhang et al, 2015). Further, the highly chlorinated PCB congeners are more likely to be adsorbed to particulate material resulting in accumulation and deposition in the sediment.…”

The distribution and concentrations of 6 indicator polychlorinated biphenyl (PCB) congeners, nos. 28, 52, 101, 138, 153 and 180, were determined in surface sediments from the North End Lake in Port Elizabeth, South Africa. Forty-two surficial sediment samples were collected from different locations covering the region that receives the majority of the industrial waste, urban effluents and runoff and thus expected to be contaminated with different degrees of contamination. The analysis was achieved by gas chromatography-mass spectrometry (GC/MS) using the internal standard method. The total PCB concentrations in the samples ranged from 1.60 to 3.06 ng·g -1 dry weight (dw). The concentrations of congener profiles showed significant differences. Generally, the highest PCB concentrations were associated with high organic matter contents and small grain size. The highly chlorinated PCBs dominated with regards to the levels in sediments. PCB 138 was the major contributor to the total PCBs and was detected at 100% of sites. This study provided a snapshot of the PCB contamination status in the North End Lake sediments, and allowed for a comparison between the investigated system and other systems worldwide.
