Halogenated flame retardants in the sediments of the Chinese Yellow Sea and East China Sea

Abstract

Halogenated flame retardants were investigated in the sediments of Yellow and East China Seas. DBDPE was the predominant contaminant and is one order of magnitude higher than BDE 209. High levels of HFRs were found in the depositional zones of the Yellow Sea. HFRs from the Bohai Sea was the major source of HFRs in the Yellow Sea. Yangtze River contributed less HFRs to the sediments of East China Sea.

Source, fate and budget of Dechlorane Plus (DP) in a typical semi-closed sea, China

“…Hu et al (2009) also reported high DDTs concentrations around the same area of the BS. Furthermore, a previous study found high levels of HFRs distributed in the depositional zones of the Yellow Sea (YS) (Li et al, 2019). Sediments collected from the Longkou coast and west of Laizhou Bay are also belong to fine silts (4.3e5.5 Ф) (Fig.…”

Legacy and novel halogenated flame retardants in seawater and atmosphere of the Bohai Sea: Spatial trends, seasonal variations, and influencing factors

“…1C), where the essential path of the current from the LB was located. In addition, the active coastal resuspension intensify in the shallow water induced by winter monsoon, which are the major factors resulting the long-distance transport of the particulates from the Bohai Sea to the Yellow Sea (Qiao et al, 2016;Li et al, 2019). Thus, for areas not strongly affected by production sources, transportation from highly polluted waters through coastal currents or water masses could further aggravate the risk of contamination and lead to widespread pollution in the marine ecosystem.…”

Effect of different zeolitic imidazolate frameworks nanoparticle‐modified β‐FeOOH rods on flame retardancy and smoke suppression of epoxy resin

“…[6] However, the flame retardants containing halogen will produce smoke and toxic gases in combustion which are harmful to the human body and environment. [7][8][9] In light of this, preparing a simple and efficient flame retardant is still a promising research direction.…”
