“…On the whole, the mass PCDD/F congener profiles of the sediment samples in the fishponds and coastal areas were dominated by more highly chlorinated PCDD/F congeners such as OCDD and OCDF, and similar results were found in the soil samples in the vicinity of an industrial complex and the Antarctic coastal environment (Kuo et al, 2015;Mwangi et al, 2016). The WHO2005-TEQ PCDD/F congener profiles were dominated by the less chlorinated PCDD/F congeners such as 1,2,3,7,3,4,7,.…”

“…Lin et al [2011] demonstrated that origins of PAHs in the surface sediment of the BS and YS were similar to those of the PAHs in PM 2.5 aerosols from the upwind area, highlighting the significant influence of atmospheric deposition of PAHs in the ECMSs. As for outputs, nearly 88.4% (494 t) of the input PAHs were buried in the bottom sediments, indicating that [Adhikari et al, 2015], NW Mediterranean [Tolosa et al, 1996], Gulf of Lions [Bouloubassi et al, 2012], Mediterranean [Lipiatou et al, 1997], SW Black Sea [Parinos et al, 2013], Gulf of Thailand [Hu et al, 2016b], Beibu Gulf, China , Pearl Estuary [S.

This study conducted the first extensive and comprehensive investigation of the regional‐scale sedimentary polycyclic aromatic hydrocarbons (PAHs) concentration, flux, and budget in the continental shelves of the Eastern China Marginal Seas (ECMSs). Surface sediment samples from multiple sites were collected and assessed, and the latest data from current research were assessed. The spatial distribution pattern of PAHs in the ECMSs was significantly influenced by the regional hydrodynamics, sediment properties (grain‐size, total organic carbon [TOC] content, and sedimentation rate), and anthropogenic impacts. Relatively higher PAHs concentrations occurred in areas with fine‐grained sediment. Results of source apportionment found that the relative proportions of PAHs showed significant regional variation, mainly influenced by socioeconomic differences between north and south China. The PAHs burial flux in the study area ranged from 11.2 to 1308 ng cm−2 yr−1 with an average value of 101 ± 104 ng cm−2 yr−1. The area‐integrated sedimentary PAHs burial flux across the ECMSs was 494 t yr−1. A mass budget calculation revealed that riverine input and atmospheric deposition were the most significant sources contributing, 28.4% and 71.6%, respectively. The study demonstrated that net PAHs transportation occurs between the Bohai Sea (BS) and Yellow Sea (YS), with a flux of approximately 10.2 t yr−1. PAHs were also transported from YS to the East China Sea (ECS), due to water exchange between the YS and ECS. Additionally, substantial amounts of PAHs in the inner shelf of the ECS were transported out of the shelf area due to cross‐shelf plume.

“…PCDD/Fs are lipophilic persistent organic compounds, which bioaccumulate in the fatty tissues and biomagnify within the food chain (Rolff et al, 1993;Henny et al, 2003). PCDD/Fs also exhibit long range transport properties and have been shown to be present in pristine environments, e.g., Antarctica (Mwangi et al, 2016). This overview will discuss the major PCDD/F sources as compiled in previous inventory studies (Bawden et al, 2004;Quaß et al, 2004;US EPA, 2006;Taiwan EPA, 2008;Fiedler, 2016).…”

This overview attempts to outline what we currently know about the PCDD/F emission inventories and the source categories therein. Besides the best available control techniques, suggestions are offered on how to reduce the PCDD/F emission factors and emission quantity of some important PCDD/F emission sources. The PCDD/F combustion sources can be classified as either stationary or mobile or minimally/uncontrolled combustion sources. The major stationary sources of PCDD/Fs are metal production processes, waste incineration, heat and power plants, and fly ash treatment plant. Crematories, vehicles, residential boilers and stoves are of key concern due to their proximity to residential areas and their relatively lower lying stacks and exhaust gases, which may result in great impact to their surrounding environment.Moreover, we offered our perspectives on how to improve the quality and representative of the PCDD/F emission factors to attain PCDD/F inventories which correspond more to reality. These points of view include: (1) PCDD/F contributions during start-up procedures of MSWIs should be considered, (2) the sampling times of stack flue gases for EAFs and secondary metal smelters should correspond to whole smelting process stages, (3) longer flue gas sampling time should be executed for power plants, (4) direct exhaust samplings from tailpipes for mobile sources, (5) development of an open burn testing facility that can reflect the real open burning conditions, and (6) long-term sampling techniques like AMESA are suggested to used exclusively for the most contributed PCDD/F stationary sources.
