“…Still coal operations were one of the top two (along with crude oil operations) activities influencing contaminant loadings in our study (Table 3). On the other hand, the overall range of ΣPCBs in surface sediments in this study was greater than that from Port Elizabeth Harbor, South Africa at 0.56-2.35 mg kg −1 (Kampire et al, 2015). The ΣPCBs levels in surface sediment of Port Elizabeth Harbor were much lower than any sediment quality guidelines but led to high accumulation in fresh tissues of blue mussels (Mytilus galloprovincialis), suggesting that greater sedimentary ΣPCBs level in Port Ningbo might pose a health risk to benthic organisms.…”

“…International and intergovernmental cooperation in monitoring the spatial and temporal trends of POPs is therefore essential in tracing the source and fate of these contaminants, especially for developing countries such as South Africa (SA), where certain legacy POPs continue to be detected at concentrations that are among the highest globally (e.g., dichlorodiphenyltrichloroethane (DDT) and hexachlorocyclohexanes (HCHs)) and where new POPs (e.g., PFOS, dechlorane, PBDEs, etc.) have emerged due to recent industrialization. − Although there are indications that the concentrations of PCBs, DDTs, and HCHs in the SA environment have decreased or been constant since the mid-1980s, , the high POP levels found in the SA human population − and other biota − still raise serious concerns.…”

The continuous disposal of persistent organic pollutants (POPs) in South Africa (SA) warrants concern about their detrimental effects on humans and wildlife. We surveyed six dolphin species (n = 90) incidentally captured in shark net installations or stranded off the SA east and south coast from 2005 to 2009 to study the POP exposure. Sousa plumbea, an inshore and estuarine species, was found to be the most contaminated by total POPs (21 100 ng g(-1) lw) of all the dolphins off SA, followed by Tursiops aduncus (19 800 ng g(-1) lw), Lagenodelphis hosei (13 600 ng g(-1) lw), and Delphinus capensis (5500 ng g(-1) lw), whereas POP levels in the offshore or pelagic delphinids were much lower. In all delphinids, dominant pollutants were dichlorodiphenyltrichloroethanes (DDTs), which represented more than 60% of the total concentration of total POPs, followed by polychlorinated biphenyls (PCBs, 30%). Concentrations of DDTs in S. plumbea and T. aduncus off SA were among the highest levels reported in delphinids globally. Approximately half of the adult T. aduncus had PCB concentrations above the effect threshold for impairment of immune functions. The concentrations of Mirex and Dieldrin in SA delphinids were higher than those found in species from other regions of the Southern Hemisphere.

“…In comparison with other studies on different mussel species (Table 4), levels of PCBs in Mytilus galloprovincialis detected by Kampire et al (2015) Published under a Creative Commons Attribution Licence congeners in mussels from the Istanbul Strait, Turkey. However, other studies revealed higher levels than this study.…”

This study investigated the effect of freshwater as a point source of PCBs contributing to a marine outfall region. Inflowing and outflowing water from the North End Lake, Port Elizabeth, was collected to determine the contamination levels of polychlorinated biphenyls (PCBs). Mussels at the outflow to the sea were also sampled. The samples were analysed by an internal standard method for 6 indicator PCB congeners using gas chromatography/mass spectrometry (GC/MS) in selected ion monitoring (SIM) mode. The total PCB concentrations in the water (dissolved plus particulate phases) ranged from 0.180 to 0.355 ng•L -1 and from 20.84 to 31.34 ng•g -1 wet weight (ww) in mussels. Lighter PCB congeners exhibited highest concentrations in the water samples while heavier PCBs were dominant in mussels. PCB-52 was the most abundant in the water samples while PCB-153 was abundant in mussels. To protect human health from the possible effects of eating fish and shellfish contaminated with PCBs, the Environmental Protection Agency regulates that the level of PCBs in water be no greater than 0.17 ng•L -1 of water. The levels of PCBs in water from the North End Lake were found to be high (0.180 -0.355 ng•L -1 ) compared to the levels recommended by EPA.
