“…There were strong and significant correlations between each POP (t-PAH, t-PCB, t-DDT and t-PBDE) with TOC ( Fig 5). Previous studies have reported similar findings when comparing TOC and POP concentrations [25,34,57,58,59]. Hence, TOC content can be considered as a useful tool to assess or surveil the concentrations of diverse organic contaminants in sediments [25,57,58].…”

Sediment profile and mud shrimp (Austinogebia edulis) from the coastal wetland of central Taiwan in 2017 and 2018 were analyzed for concentration, source, and composition of persistent organic pollutants (POPs) including polycyclic aromatic hydrocarbon (PAHs), polybrominated diphenyl ethers (PBDEs), organochlorine pesticides (OCPs; DDT and HCB), and polychlorinated biphenyls (PCBs). Sediment profiling indicated PAH concentrations reaching 254.38 ng/g dw in areas near industrial areas and PAH concentrations of 41.8 and 58.42 ng/g dw in sampling areas further from industrial areas, suggesting that the determining factor for spatial distribution of POPs might be proximity to contaminant sources in industrial zones. Based on molecular indices, PAHs were substantially of both pyrolytic and petrogenic origins. The main sources for PCBs were Aroclor 1016 and 1260 and the congener BDE-209 was the dominant component among PBDE congeners. While we were unable to obtain live mud shrimp samples from the heavily contaminated areas, in samples from less contaminated areas, the risk assessment on mud shrimp still illustrated a borderline threat, with DDT concentrations almost reaching standardized values of Effects Range-Low (ERL). Bioaccumulation factors for DDTs and PCBs (17.33 and 54.59, respectively) were higher than other POPs in this study. Further study is essential to assess and understand the impact of these chemicals on the wetland ecosystem near this heavily industrialized area.

“…The detection frequency of BDE 209 in all sediments was 98.0%. Concentrations of BDE 209 in the three river sediment samples (0.05 ng g À1 dw in site H1, 1.94 ng g À1 dw in site H2 and 7.82 ng g À1 dw in site H3) were much lower than those reported for the Dongjiang River (3.83e2517 ng g À1 dw) , Shanghai River (n.d. e 189 ng g À1 dw) (Wang et al, 2015b), and Korea' s industrialized bay (2.0e2253 ng g À1 dw) (Moon et al, 2007a). The mean BDE 209 concentration in all the coastal sediments was 0.68 ng g À1 dw in this study, which was lower than the levels found in other marine sediments of China, such as in the Bohai Sea (2.29 ng g À1 dw) , East China Sea (6.4 ng g À1 dw) (Li et al, 2012), PRE (14.2 ng g À1 dw) and Xiamen offshore area (14.94 ng g À1 dw) ; however, the concentration detected in this study was similar to the levels found in the Yangtze River Delta (0.41 ng g À1 dw) .…”

a b s t r a c tThe distribution characteristics and potential sources of polybrominated diphenyl ethers (PBDEs) and alternative brominated flame retardants (aBFRs) were investigated in 54 surface sediment samples from four bays (Taozi Bay, Sishili Bay, Dalian Bay, and Jiaozhou Bay) of North China's Yellow Sea. Of the 54 samples studied, 51 were collected from within the four bays and 3 were from rivers emptying into Jiaozhou Bay. Decabromodiphenylethane (DBDPE) was the predominant flame retardant found, and concentration ranged from 0.16 to 39.7 ng g À1 dw and 1.13e49.9 ng g À1 dw in coastal and riverine sediments, respectively; these levels were followed by those of BDE 209, and its concentrations ranged from n.d. to 10.2 ng g À1 dw and 0.05e7.82 ng g À1 dw in coastal and riverine sediments, respectively. The levels of DBDPE exceeded those of decabromodiphenyl ether (BDE 209) in most of the samples in the study region, whereas the ratio of DBDPE/BDE 209 varied among the four bays. This is indicative of different usage patterns of brominated flame retardants (BFRs) and also different hydrodynamic conditions among these bay areas. The spatial distribution and composition profile analysis indicated that BFRs in Jiaozhou Bay and Dalian Bay were mainly from local sources, whereas transport from Laizhou Bay by coastal currents was the major source of BFRs in Taozi Bay and Sishili Bay. Both the P PBDEs and P aBFRs (sum of pentabromotoluene (PBT), 2,3-diphenylpropyl-2,4,6-tribromophenyl ether (DPTE), pentabromoethylbenzene (PBEB), and hexabromobenzene (HBB)) were at low concentrations in all the sediments. This is probably attributable to a combination of factors such as low regional usage of these products, atmospheric deposition patterns, coastal currents transportation patterns, and degradation processes for higher BDE congeners. This paper is the first study that has investigated the levels of DBDPE in the coastal sediments of China's Yellow Sea.

“…We collected data from the residents of four cities in China including Beijing, Shanghai, Qingdao, and Weifang. These cities were chosen because they had multiple communities that were going through environmental developments based on the homepage of the National Development and Reform Commission and reported to have some environmental issues (e.g., wetland loss and chemical pollution; Mi, Pan, Yu, & Wei, ; Pu & Fu, ; Wang et al, ; Yuan et al, ). The Commission listed Beijing, Shanghai, Qingdao, and Weifang as having 25, 3,437, 1,600, and 1,503 communities, respectively, under developments at the time of data collection.…”

This study drawing concepts from the fields of sociology, organizational behavior, and marketing examines residents' perceptions of justice in relation to environmental development. Although prior research raised issues related to environmental development from the justice perspective, very little is known about how residents perceive justice related to environmental development. Therefore, our study examines residents' perceptions of justice and how those perceptions influence the relationship with the government. More specifically, the study proposes that four types of justice (distributive, procedural, interpersonal, and informational) are related with the residents' trust in the government, which predicts their intentions to support for future projects and the government. To test the proposed model, we collected data from residents of four cities in China that were going through environmental development projects. The results of the study show perceptions of distributive justice and interpersonal justice have a significant positive effect on the residents' trust in the government and the environmental development. The study also finds that trust in the government and trust in the environmental development are positively related with residents' intentions to support the government and additional environmental developments. Our finding, however, does not support that either perceptions of procedural justice or perceptions of informational justice are important in the Chinese context. Implications of the study are presented. KEYWORDS environmental justice, social exchange theory, support intention, sustainable development, trust in the government
