“…Notably, several POPs have been shown to disrupt thyroid hormones, affect liver and kidney morphology, neurobehavioural development and reproductive function, and have fetal toxicity/teratogenicity in lab animals and wildlife [ 24 ]. Based on our earlier toxicology studies, different POPs have been accumulated and biomagnified in several passerines and waterbirds [ 17 , 25 ], and the level of PBDEs is dependent on bird dietary or trophic position (carnivore > insectivore > frugivore) [ 26 – 28 ]. Now that e-waste pollution persisted for more than three decades in South China, it is urgent to know how population abundance and species diversity of farmland birds changed compared with reference sites, and which species-specific or guild-dependent traits are functionally important in determining the susceptibility to e-waste pollution.…”

Indirect effects of electronic waste (e-waste) have been proposed as a causal factor in the decline of bird populations, but analyses of the severity impacts on community assembly are currently lacking. To explore how population abundance/species diversity are influenced, and which functional traits are important in determining e-waste susceptibility, here we surveyed breeding and overwintering birds with a hierarchically nested sampling design, and used linear mixed models to analyze changes in bird assemblages along an exposure gradient in South China. Total bird abundance and species diversity decreased with e-waste severity (exposed < surrounding < reference), reflecting the decreasing discharge and consequent side effects. Twenty-five breeding species exclusively used natural farmland, and nine species decreased significantly in relative abundance at e-waste polluted sites. A high pairwise similarity between exposed and surrounding sites indicates a diffuse effect of pollutants on the species assembly at local scale. We show that sensitivity to e-waste severity varies substantially across functional guild, with the prevalence of woodland insectivorous and grassland specialists declining, while some open farmland generalists such as arboreal frugivores, and terrestrial granivores were also rare. By contrast, the response of waterbirds, omnivorous and non-breeding visitors seem to be tolerable to a wide range of pollution so far. These findings underscore that improper e-waste dismantling results in a severe decline of bird diversity, and the different bird assemblages on polluted and natural farmlands imply species- and guild-dependent susceptibility with functional traits. Moreover, a better understanding of the impact of e-waste with different pollution levels, combined multiple pollutants, and in a food-web context on bird is required in future.

“…Concentrations of PCBs, DDTs, and HCHs were quantified using the gas chromatograph-mass spectrometer described above with a capillary column (J&W DB-5MS, 60 m long with internal diameter at 0.25 mm and film thickness at 0.25 μm) following the running conditions described by Sun et al (2014). Sixty-five PCB congeners, DDT and its metabolites (DDD, DDM, DDMU, and DDE), and HCHs (α-, β-, γ-, and δ-isomers) were detected in the sediment samples, respectively.…”

“…Also in Sishili Bay are Mytilus edulis, Chlamys farreri, Argopectens irradians, Crassostrea gigas and Ostrea plicatula. In recent years, environmental pollution has become a major concern, and numerous studies have focused on typical pollutants such as heavy metals, for instance, Fe, Mn, Zn, Cu, Pb, Ni, Cr, and Cd (Youssef, 2015), and persistent organic pollutants (POPs) including PAHs, PCBs, DDTs, OCPs or OCP chemicals and so on (Eremina et al, 2016;Ilyina et al, 2008;Sun et al, 2014;Mumtaz et al, 2015), but the study of SEM as an ocean pollutant has been neglected here worldwide. The function as the marine environment, especially as a pollutant sink, is important for socioeconomic development and human health (Moore, 2008;Keeling, 2007).…”

• An ultra performance liquid chromatography-tandem mass spectrometry was developed for determining Semicarbazide, with short time, high sensitivity and accurate characterization.• The temporal and spatial distribution of Semicarbazide in seawater was measured and the highly polluted areas identified and traced.• The distribution of Semicarbazide in sediment and shellfish was also analyzed.• An early warning value 0.05 μg/L in seawater was deduced. A verified method for measuring Semicarbazide (SEM) in seawater, sediments, and shellfish was developed based on ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). A total of 30 stations were radially distributed in Jincheng and Sishili Bays in the Bohai and Yellow Seas, and 1025 monitoring data were collected in 41 voyages, 615 seawater samples, 320 sediment samples and 90 shellfish samples. The concentration ranged from 0.011 μg/L to 0.093 μg/L and 0 to 0.75 μg/kg in seawater and shellfish respectively, but SEM in sediment was all below the limit of detection. Temporal and spatial distribution of SEM was investigated using multivariate analysis to estimate the degree of SEM pollution. Based on the SEM concentration in the three sample types, together with our previous findings, early warning values were deduced for SEM in seawater, and the developed method overcame shortcomings with existing technologies. The results may be helpful to draft national baseline values for SEM in seawater and sediments, and provide a scientific basis for assessing the impacts of SEM on marine ecology and human health.
