“…The total PBDE concentrations of liver, muscle, and adipose tissues ranged from 29.1-252.2, 10.5-48.9 and 4.36-106.4 ng/g lw, respectively. The average ΣPBDEs concentration in muscle samples of short-tailed mamushi (23.1 ng/g lw) was close to those of red-backed rat snake analyzed in the present study (33.2 ng/g lw) and our previous report (28.3 ng/g lw)(Zhou et al, 2016b), but was 1-2 orders of magnitude lower than of water snakes sampled from e-waste sites(Liu et al, 2018;Wu et al, 2013;Wu et al, 2020). Additionally, a signi cant positive correlation was observed between body weight of snakes and muscle concentrations of PBDEs in all samples (r 2 = 0.56, p < 0.01; data not shown).…”

In many developing regions, the rapid development in industrialization and urbanization has caused adverse impact on the aqueous ecology and environment. However, there is limited information available on the tissue-specific burden and biomagnification of polybrominated diphenyl ethers (PBDEs) in biota. In the present study, the tissue concentration and distribution of tri- to deca-BDEs were analyzed in terrestrial short-tailed mamushi (Gloydius Brevicaudus) and semi-aquatic red-backed rat snake (Elaphe Rufodorsata) from the Yangtze River (ChangJiang) Delta, Southeastern China. The total PBDE concentrations of liver, muscle and adipose tissues in two snakes ranged from 29.1-252.2, 10.5-48.9 and 4.36-106.4 ng/g lw, respectively. The congener patterns of PBDEs exhibited the significant difference between two snakes, which may be attributed to different feeding habits and dermal exposure. Tissue-specific burdens in snakes suggested that adipose tissue served as a dominant storage and sink for PBDEs (85.1% for red-backed rat snake and 80.0% for short-tailed mamushi, respectively) compared to liver (8.1% and 12.5%, respectively) and muscle (6.9% and 7.5%, respectively) tissues. Biomagnification potential of PBDEs was investigated via black spotted frogs-red-backed rat snake food chain. The biomagnification factors (BMFs) of tri- to deca-BDEs were in a range of 0.74 to 4.30. Tetra- to octa-BDEs generally exhibited biomagnification potentials through the frog-snake food chain. Moreover, parabolic relationship was observed between BMFs and log Kow of PBDE congeners, and it may be resulted from the combined effects of chemical’s hydrophobicity and molecular size. This research, thereby provides data support for biological monitoring being concerned about liver, muscle and adipose tissues of animals.

“…This region had been heavily polluted by e-waste-associated chemicals after a large amount of unwanted e-waste was carelessly discarded. Details of the sampling site and sampling methods were provided in our previous study. , Insects including mantis ( Tenodera sinensls ), dragonfly (dragonfly 1: Aeshnidae rambur , dragonfly 2: Libellulidae rambur ), grasshopper ( Oxya chinensis ), cricket ( Gryllulus chinensis ), mole cricket ( Gryllotalpa orientalis ), and beetle ( Anomala corpulenta ) were collected between September 2015 and November 2016. The reasons why not we collected samples on once were as follows: (1) different insects and the terrestrial biota samples have different life-circles; (2) we cannot collected enough sample in one sampling campaigns considering small sampling area.…”

Studies on the biomagnification of short-and medium-chain chlorinated paraffins (SCCPs and MCCPs) in terrestrial ecosystems and their bioamplification during metamorphosis in insects and amphibians are scarce. Therefore, this study sought to characterize the occurrence and trophic dynamics of SCCPs and MCCPs in an insect-dominated terrestrial food web in an e-waste recycling site in South China. Median ∑SCCPs and ∑MCCPs concentrations in the organisms ranged from 2200 to 34 000 ng/g lipid weight and from 990 to 19 000 ng/g lipid weight, respectively. The homologue profiles of CPs in the predators were distinct from those in insects, presenting more short chain-high chlorinated congeners (C 10−12 Cl 8−10 ). The trophic magnification factors (TMFs) of ∑SCCPs and ∑MCCPs were 2.08 and 2.45, respectively, indicating biomagnification in the terrestrial food web. A significant positive relationship between the TMFs and octanol-air partition coefficients was observed. TMFs were also positively correlated with chlorination degree but did not correlate with carbon chain length. Nonlinear correlations between metamorphosis-associated bioamplification and the octanol−water partition coefficients of SCCPs and MCCPs were observed for insects, whereas negative linear correlations were observed for amphibians, which suggested species-specific alterations to the chemicals during metamorphosis.

“…Additionally, the presence of Al, Cr, Ni, Cu, Zn, and Sn as main elements in MBs components (i.e., capacitors, processors, etc.) has been recently reported [ 18 , 21 , 22 ]. Although different types of organic chemical substances were not measured, the high levels of TOC could depict the presence of organic toxicants, mainly released during the PCMB leaching process.…”

“…In all cases, their entrance into the environment is considered inevitable through leaching and transport with water, air and soil, thus contaminating both surface and groundwater bodies, as well as coastal basins [ 8 , 11 ]. For instance, several monitoring studies performed near e-waste treatment and workshop sites in developing countries revealed air, soil, and surface waters contamination with e-waste leaching components, mainly heavy metals ([ 12 , 13 , 14 , 15 , 16 , 17 ], as well as other toxic substances such as dioxins, polyaromatic hydrocarbons (PAHs), polychlorinated biphenyl (PCBs), brominated flame retardants (BFRs), polybrominated diphenyl ethers (PBDEs), and polychlorinated dibenzo-p-dioxin furans (PCDD/Fs) [ 18 ].…”

Considering that electronic wastes (e-wastes) have been recently recognized as a potent environmental and human threat, the present study aimed to assess the potential risk of personal computer motherboards (PCMBs) leaching into aquatic media, following a real-life scenario. Specifically, PCMBs were submerged for 30 days in both distilled water (DW) and artificial seawater (ASW). Afterwards, PCMBs leachates were chemically characterized (i.e., total organic carbon, ions, and trace elements) and finally used (a) for culturing freshwater (Chlorococcum sp. and Scenedesmus rubescens) and saltwater (Dunaliella tertiolecta and Tisochrysis lutea) microalgae for 10 days (240 h), (b) as the exposure medium for mussel Mytilus galloprovincialis (96 h exposure), and (c) for performing the Cytokinesis Block Micronucleus (CBMN) assay in human lymphocytes cultures. According to the results, PCMBs could mediate both fresh- and marine algae growth rates over time, thus enhancing the cytotoxic, oxidative, and genotoxic effects in the hemocytes of mussels (in terms of lysosomal membrane impairment, lipid peroxidation, and NO content and micronuclei formation, respectively), as well as human lymphocytes (in terms of MN formation and CBPI values, respectively). The current findings clearly revealed that PCMBs leaching into the aquatic media could pose detrimental effects on both aquatic organisms and human cells.
