Polybrominated diphenyl ether concentrations in sediments from the Northern Arabian Gulf: Spatial and temporal trends

Histopathology and contaminant concentrations in fish from Kuwait’s marine environment

“…While BDE 28 was not detected in the current study it is interesting to note that BDE 47 (59-74%) and BDE 99 (3-20%) and BDE 100 (11-20%) were also the dominant congers in the study by Gevao et al (2011). Studies of PBDE sediment contamination indicated that BDE 153, 154, 183 and 209 were most dominant forms of PBDEs detected (Gevao et al, 2014;Lyons et al, this issue). The study by Lyons et al (this issue) analysed sediments collected from the same sites as used this current study and found all PBDEs analysed in A. thalassinus to be below the analytical limits of detection.…”

Historic and contemporary contamination in the marine environment of Kuwait: An overview

“…Values of PBDEs ranged from 0.1 to 4 ng g À1 dw. Studies conducted on a wider spatial scale, covering offshore sediment samples along with those within Kuwait Bay reported a generally lower level of PBDE contamination although the composition of PBDE differed with BDE 209 the dominant conger (Gevao et al, 2014;. While the mix of congeners analysed differed between all the studies, the overall levels were similar with P PBDEs ranging from 0.1 to 0.5 ng g À1 (Gevao et al, 2014) and <0.02 to 0.35 ng g À1 dw (Lyons et al, this issue-a).…”

The analysis of core samples taken at the entrance to Kuwait Bay demonstrated that detectable levels of PBDE first appeared above background concentrations in the mid-1950s with peak inputs associated with periods of military conflict (Gevao et al, 2014).…”

“…The data available in Kuwait are mainly restricted to a handful of studies (Gevao et al, 2006a;Gevao et al, 2009;Gevao et al, 2014;. These compounds are of environmental concern due to their persistence, high lipophilicity and resistance to degradation (Allchin et al, 1999;Gevao et al, 2009).…”

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

“…This result suggested that deca-BDE has been used as the dominant PBDE product in this area (Chen et al, 2006;Zou et al, 2007). Similar to the Northern Arabian Gulf (Gevao et al, 2014), the BDE183 concentrations were under the detection limits in most of the sediment samples. BDE183 is a primary component of commercial octa-BDE mixture and has been prohibited for use due to its high toxicity (Darnerud et al, 2001).…”
