Distribution and accumulation of polybrominated diphenyl ethers (PBDEs) in Hong Kong mangrove sediments

Insights into spatially and temporally co-occurring polybrominated diphenyl ethers in sediments of the East China Sea

“…In addition, the sampling locations in this study were farther from the mainland than those previously studied, thus the collected sediments potentially had fewer land-based influences. Compared with other areas, the concentrations of R 8 PBDEs in this study were comparable to the concentrations in sediments from the coast of Korea (0.05-0.90 ng g À1 ) (Moon et al, 2007), and much lower than those of the Pearl River Estuary (0.04-94.7 ng g À1 ) (Mai et al, 2005) and the coast of Hong Kong (0.57-14.4 ng g À1 ) (Zhu et al, 2014). The concentrations of BDE209 were equivalent to those in the Daliao River Estuary (0.11-1.84 ng g À1 ) (Zhao et al, 2011) but were significantly lower than those in the Pearl River Estuary (0.4-7340 ng g À1 ) (Mai et al, 2005).…”

Bioaccumulation and biomagnification of halogenated organic pollutants in mangrove biota from the Pearl River Estuary, South China

“…Mangrove sediments can act as sinks for varieties of man-made pollutants (Vane et al, 2009;Zhang et al, 2014). To date, several studies have been conducted on PCBs, DDTs and PBDEs contamination in mangrove sediments (Zheng et al, 2000;de Souza et al, 2008;Zhu et al, 2014;Zhang et al, 2015), however, little information on bioaccumulation and biomagnification of these HOPs, especially for PBDEs, DP and DBDPE, in mangrove ecosystems, could be found in literature.…”

Particulate Size Distribution and Sources Evaluation of n-Alkanes during Long-Term Haze Episode around Chaohu Lake, Eastern China

“…Fig. 7 shows the Lundgren diagrams (dC/CdlogD p vsD p ) for all samples collected at 11 sites, which is a useful method for comparing the concentrations of coarse and fine particles (Zhu et al, 2014). The n-alkanes in all sampling sites with the exception of ZM and SH revealed a bimodal distribution.…”
