“…This range fits the range of mussels from the Swedish Baltic Sea, in which 7 MeO-PBDEs were detected at concentrations up to 420 ng/g lw (Löfstrand et al, 2011). Also, Mediterranean mullets have similar content of MeO-PBDEs, up to 401 ng/g lw (Ben Ameur et al, 2011). In the present and previous works, 2′-MeO-BDE-68, 6-MeO-BDE-47 and 5-MeO-BDE-47 tend to be the most occurring MeO-PBDEs; the level of the latter being usually the lowest in fish.…”

PBDEs (congeners 28, 47, 99, 100, 153, 154, 183, 209), HBCD (α, β, γ), emerging brominated flame retardants (PBEB, HBB and DBDPE), dechloranes (Dec 602, 603, 604,, TBBPA, 2,4,6-TBP and MeO-PBDEs (8 congeners) were analysed in commercial seafood samples from European countries. Levels were similar to literature and above the environmental quality standards (EQS) limit of the Directive 2013/39/EU for PBDEs.Contaminants were found in 90.5 % of the seafood samples at n. d.-356 ng/g lw (n. d.-41.1 ng/g ww). DBDPE was not detected and 2,4,6-TBP was detected only in mussels, but at levels comparable to those of PBDEs. Mussel and seabream were the most contaminated species and the Mediterranean Sea (FAO Fishing Area 37) was the most contaminated location. The risk assessment revealed that there was no health risk related to the exposure to brominated flame retardants via seafood consumption. However, a refined risk assessment for BDE-99 is of interest in the future. Moreover, the cooking process concentrated PBDEs and HBB.

“…Table 5 provided further information. It was reported that PBDEs and MeO-PBDEs was together present in fish samples at relatively high levels [11][12][13][15][16]. Considering that MeO-PBDEs were a novel class of pollutants, contamination of MeO-PBDEs in these reports was more concerned than that of PBDEs in our opinion.…”

“…MeO-PBDEs were also detected in mullet (Mugil cephalus) and sea bass (Dicentrarchus labrax) from Bizerte Lagoon, Tunisia ranging from 6.46 to 798 ng g -1 lipid weight [12]. Moreover, MeO-PBDEs were also detected in fish from the Bohai Sea and the Donghai Sea, China ranging from less than detection to 3.2 ng g -1 dry weight [13].…”

“…In marine wildlife MeO-PBDEs were first analyzed in the aquatic Baltic environment, e.g., seal and fish from the Baltic Sea in year 1997 [9]. In recent years, MeO-PBDEs have been paid special attention mainly in biotic samples all over the world, and were found in eggs of white-tailed sea eagles breeding in different regions of Sweden [10], in fish and shellfish samples from the Mediterranean Sea [11], in mullet (Mugil cephalus) and sea bass (Dicentrarchus labrax) from Bizerte Lagoon, Tunisia [12], in mollusk and fish from the Bohai Sea and the Donghai Sea, China [13], in blue mussels from the Baltic Sea, Sweden [14], in fish from local supermarket in Catalonia, Spain [15], and in Japanese common squid (Todarodes pacificus) from Korean offshore waters [16]. MeO-PBDEs are major contributors to the persistent organobromine load in sub-Arctic and Arctic marine mammals, covering a time period of more than 20 years [17].…”

“…To our knowledge, there is little information about the degree of MeO-PBDEs and PBDEs contamination in channel catfish, crayfish, fish feeds and fishmeal from the region in China. In addition, there are only few literatures about simultaneous analysis method and contamination of MeO-PBDEs and PBDEs in fish [11][12][13][16][17], especially no literature about analysis method and contamination in crayfish, fish feeds and fishmeal. The analysis of PBDEs and MeO-PBDEs in biological samples is difficult because they are usually present at µg kg -1 levels and the matrices involved are generally complex.…”

PBDEs are widely used brominated flame retardant, which are increasingly reported in the environment.MeO-PBDEs are structural analogs to PBDEs, and reported as natural products and novel pollutants present in the environment. Concentrations of thirteen PBDEs and eight MeO-PBDEs in a large number of channel catfish, crayfish, fish feeds and fishmeal collected from Hubei province of China were investigated in this study. A fast isotopic dilution GC-MS method was firstly developed to simultaneously determine thirteen PBDEs and eight MeO-PBDEs in channel catfish, crayfish, fish feeds and fishmeal in this study, and especially for the first time MeO-PBDEs and PBDEs in crayfish, fish feeds and fishmeal. Pressurized liquid extraction and multi-layer silica gel column chromatography cleanup were used, and some important steps and crucial parameters were modified and intensified compared with other literatures. Besides, the conditions of GC and MS were also optimized. The limits of quantitation values of 0.25-5, 1-5 µg kg -1 wet weight in channel catfish and crayfish were calculated for PBDEs and MeO-PBDEs, respectively; so did 1-20, 4-20 µg kg -1 wet weight in fish feeds and fishmeal. In addition, good repeatability and accuracy of the whole method were achieved. The established methods were therefore suitable for the simultaneous determinations of thirteen PBDEs and eight MeO-PBDEs in these samples at trace contamination levels. Using the established methods, PBDEs or MeO-PBDEs emerged in 2 of 80 channel catfish, 1 of 80 crayfish, 6 of 60 fish feeds and 4 of 40 fishmeal, and in low-µg kg -1 wet weight for these samples.

Environmental micro-organic pollutants accumulate in abiotic parts of the aquatic ecosystems. This study was aimed to make residue, source, and composition profiles of some micro-organic pollutants, consisting 16 polycyclic aromatic hydrocarbons (PAHs), seven polychlorinated biphenyls (PCBs), nine organochlorine pesticides (OCPs), and six polybrominated diphenyl ethers (PBDEs) in water and sediment from Kirmir Stream (Ankara, Turkey) between 2017 and 2018 as seasonal based. In water and sediment samples, total PAHs were determined to be 15.68 and 1216.19 μg/kg, respectively. Among the OCPs, only DDE was detected in sediment samples and its total concentration was 1768.92 μg/kg. Other OCPs, PCBs, and PBDEs were below the limit of quantification. Having molecular structure, found PAHs in water and sediments were originated from pyrolytic and petrogenic. Thus, this study will be very useful to provide background information for further studies on the contamination with environmental micro-organic pollutants in the region.
