“…This concentration of total PCBs was slightly lower than those reported worldwide in other aquaculture sediments, e.g. the concentration of PCBs in surface sediment of aquaculture areas in New Brunswick, Canada (1.07e10.4 ng g À1 ) (Sather et al, 2006), mariculture area along the coast of Hong Kong and mainland China (5.10e11.0 ng g À1 , mean 7.96 ng g À1 ) (Wang et al, 2011), Xiangshan Bay, China (15.2 mgkg À1 ) (Lin et al, 2020). Finally, in the present work, the PCB levels in mariculture surface sediments of the shrimp farms were relatively low.…”

“…McLeese et al (1980) also reported BSAF value for shrimp exposed to PCB mixed with either a muddy or sandy sediment, ranged from 3.6 to 10.9. A recent research by Lin et al (2020) showed that the BSAF value of the P 7 PCBs for shrimp was 8.84 in Xiangshan Bay, China, indicating that the organism was readily subjected to bioaccumulation of PCBs from sediments. Compared to the result of P 7 PCBs concentration found in this study, the estimated concentration in shrimp will be 19.8 ± 12.7 mg kg À1 and 19.3 ± 11.5 mg kg À1 in Tegal and Pemalang, respectively.…”

“…A worrying concentration found for the most toxic of 7 PCBs, i.e. PCB118, in terms of BASF value, since Lin et al (2020) demonstrated that PCB 118 was more accumulated in organisms, with the value of 111.1. In addition, PCB 118 was detected in all regions, and among PCBs, it presented as the highest detected PCB level in Tegal.…”

Background Fish is one of the main sources of food and income in Tanzania, with 25% of the population depending on fishing activities as a source of food, income, and employment. But fish consumers are vulnerable to exposure to toxic pollutants including PCBs due to the lipophilic nature of the pollutants which accumulate in fish. Results The estimated mean NDL PCBs concentration level was 0.84 ng/g w/w and the mean fish consumption rate among fishermen was 0.4 kg/day. Mean exposure of the fishermen and fish vendors to total PCBs ranged between 9.62 and 36.12 ng/kg bw/day depending on the estimation scenario (lower bound/upper bound) for both normal and higher fish consumers. The general population exposure to total PCBs was 0.4 and 0.8 ng/kg bw/day in lower‐bound and upper‐bound estimation scenarios respectively. The estimated lifetime carcinogenic and non‐carcinogenic hazard indices from intake of estimated total PCBs by fishermen and fish vendors exceeded the recommended tolerable daily intake, TDI, raising serious concerns for adverse health effects to fishermen and fish vendors. However, for the general population, there was no concern for any potential health effects as the estimated hazard indices were far below the recommended levels for intake of total PCBs. Conclusion The exposure levels of fishermen and fish vendors to PCBs via consumption of Rastrelliger kanagutra (Indian mackerel) in Dar es Salaam are high enough to course serious health concerns, especially for high fish consumers and efforts should be taken to encourage diversification of fish species intake.

“…Thus, concerns over the toxicity and persistence of PCBs in the environment led to the usage of PCBs was banned in the 1970s (Dodoo et al, 2013). Nevertheless, PCBs continue to enter nearby waterways in most developing countries through the uncontrolled spillage, stream transport, surface runoff and atmospheric deposition and that accumulated through the food pyramid (Beate and Ralf, 2004;Lin et al, 2020;Xiao et al, 2021). Recent surveys have found that the concentration of PCBs ranges from 15.1 to 57.9 ng/g (mean: 34.5 ng/g) in the sediment of the Minjiang River in southern China (Zhang et al, 2003).…”

Polychlorinated biphenyls (PCBs) are environmentally persistent and highly toxic organochlorine compounds that may cause toxic effects on aquatic animals. In this study we assess the toxic effect of PCBs on a bivalve used in aquaculture, the clam Cyclina sinensis. To this end, individuals of C. sinensis were exposed for 72 h at two PCB concentrations (1 ng/L and 10 ng/L) and control (absence of PCBs). At the end of the exposure, the hemolymph, hepatopancreas, and gills samples of C. sinensis were harvested for analysis of the enzyme activity and histology. The results showed that acute PCBs exposure decreased the survival rate of C. sinensis compared to the control. Acute PCBs exposure up-regulated the enzymatic activity of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) and the content of malondialdehyde (MDA) in the hemolymph of C. sinensis, while down-regulated the non-specific enzymatic activity of alkaline phosphatase (AKP). For the hepatopancreas, 1 ng/L PCBs exposure up-regulated the enzymatic activity of SOD while down-regulated the enzymatic activity of CAT of C. sinensis. In the gill, the enzymatic activity of CAT decreased significantly and the MDA content increased of C. sinensis after 10 ng/L PCBs exposure. Moreover, histological observations showed that acute exposure to PCBs caused loss of gill filaments and lateral cilia and shortening of their length, in the studied organism. The present study will provide valuable reference data for marine shellfish aquaculture and toxicology research.
