“…Meanwhile α-HBCD has a longer half-life [ 37 ]. The high α-HBCD contributions to the total HBCD concentrations in our samples may therefore have been caused by the bioisomerization of β- and γ-HBCD into α-HBCD and by α-HBCD being degraded more slowly than γ-HBCD under anaerobic conditions [ 16 , 42 , 43 ]. Isomer transport, accumulation, and transformation processes in the environment may also have contributed to the high contributions of α-HBCD to the total HBCD concentrations [ 12 , 44 ].…”

As one of the most widely used brominated flame retardants, hexabromocyclododecane (HBCD) is found widely in the environmental media. In this study, the content and spatial distribution of HBCD and risk posed by HBCD in surface sediment in the Weihe River Basin in Northwest China were investigated. The HBCD concentration ranged nd–4.04 ng/g dw with the mean was 0.45 ng/g dw. The major source of HBCD in surface sediment was local point discharge. The distribution profiles of α-, β-, γ-HBCD were 24.7–87.9%, 0–42.0%, and 0–67.1%, respectively. Specially, α-HBCD was the dominating isomer in most sample sites. This differed significantly from that in HBCD technical product, which might be attributed to the different degradation rates and inter-transformation of the three HBCD isomers. Risk quotient method was used to assess the potential risk posed by HBCD in sediment. HBCD do not pose strong risks to aquatic algae organisms in the Weihe River Basin.

“…Karena itu, terdapat kekhawatiran tentang tingkat pencemaran lingkungan dan hubungannya dengan risiko kesehatan termasuk dari konsumsi ikan yang tercemar. Sementara itu, area budidaya ikan telah diketahui sebagai salah satu sumber pencemaran ke lingkungan sekitar (6) , termasuk memberikan paparan polutan ke dalam produk ikan budidaya (6,7) , dimana diantaranya polybrominated diphenyl ethers (PBDEs) adalah polutan yang menjadi perhatian (6,7) . Sejalan dengan hal tersebut, maka penelitian untuk menilai risiko dan manfaat konsumsi ikan karena pencemaran juga telah meningkat, termasuk dengan senyawa PBDEs (7,8,9) .…”

In regard to food security and safety, the need for evaluation of the risks and benefits of fishery products due to environmental contamination by polybrominated diphenyl ethers (PBDEs) has become a matter of concern. In this study, PBDEs were determined in farmed and wild groupers obtained from a mariculture area in Lampung to understand the contamination status and its differences between farmed and wild groupers, and to evaluate the proportion of their congeners as well as risks and benefits of consuming contaminated fish. Fourteens PBDE congeners from mono- to deca BDE were analyzed from samples stored in es-Bank using gas chromatography equipped with mass spectrometry detector (GC-MS). PBDEs were detected in all the samples of the present study, with the levels being significantly higher (p<0.01) in farmed (1.1–6.2 ng/g lipid wt) than in wild groupers (0.20–1.1 ng/g lipid wt). Analysis of fish feeds indicated that the higher level of contaminants in farmed groupers most likely came from the commercial fish feed which they consumed. The study confirms relatively high concentrations of these compounds in farmed than wild fish. However, the levels still bellow to those farmed fish reported worldwide but have similar composition pattern of congeners being BDE-47 as predominant congener. The evaluation of PBDEs concentration in groupers showed that the levels were still bellow than fish tissue guideline. Furthermore, the estimated daily intake of PBDEs was also far bellow the reference dose values (RfDs) and/or Minimum Risk Levels (MRL), indicating minimum risk caused by these pollutants to groupers as well as to Indonesian from consuming fish. Keywords: contamination, PBDEs, farmed grouper, wild grouper, health risk. ABSTRAK Berkaitan dengan isu ketahanan dan keamanan pangan, evaluasi terhadap resiko dan manfaat dari produk perikanan terhadap pencemaran lingkungan dari polybrominated diphenyl ethers (PBDEs) telah menjadi perhatian. Pada penelitian ini, PBDEs dideterminasi pada ikan kerapu budidaya dan kerapu liar dari daerah Lampung untuk mengetahui status kontaminasi dan perbedaan diantara dua kelompok kerapu, mengevaluasi proporsi konjener penyusun serta risiko dan manfaat dari mengkonsumsi ikan yang terkontaminasi. Empat belas konjener PBDEs dari mono- sampai ke deka BDE dianalisis dari sampel yang tersimpan di es-BANK menggunakan kromatografi gas yang dilengkapi dengan detektor spektrometri massa (GC-MS). PBDEs terdeteksi di semua sampel kerapu, dengan konsentrasi secara signifikan lebih tinggi (p<0,01) pada kerapu budidaya (1,1–6,2 ng / g lipid wt) daripada di kerapu liar (0,20–1,1 ng / g lipid wt). Analisis pakan ikan menunjukkan bahwa tingkat kontaminan yang lebih tinggi di kelompok kerapu budidaya ini kemungkinan berasal dari pakan ikan komersial yang mereka konsumsi. Studi ini menegaskan bahwa ikan budidaya mempunyai konsentrasi PBDEs yang lebih tinggi daripada ikan liar. Namun demikian, kadar konsentrasi PBDEs pada kerapu budidaya ini masih lebih rendah daripada yang dilaporkan pada beberapa ikan budidaya di seluruh dunia, tetapi memiliki pola komposisi konjener yang sama dimana BDE-47 merupakan konjener yang dominan. Evaluasi konsentrasi PBDEs pada kerapu memperlihatkan bahwa kadarnya masih di bawah standar rujukan untuk konsentrasi pada jaringan ikan. Selanjutnya, perkiraan asupan harian PBDEs juga masih jauh di bawah nilai rujukan dosis referensi (RfDs) dan/atau Tingkat Risiko Minimum (MRL), menunjukkan potensi dampak yang rendah pada jaringan ikan itu sendiri maupun kesehatan orang Indonesia karena mengkonsumsi kerapu. Kata kunci: kontaminasi, PBDEs, kerapu budidaya, kerapu liar, resiko kesehatan

“…It can be found in the market under different varieties, such as general-purpose polystyrene (GPPS), high impact polystyrene (HIPS), expanded polystyrene (EPS), and extruded polystyrene (XPS). Because of its characteristics, PS has been widely used as a packaging material for food and non-food applications, as a building insulator, on the manufacture of household items, on aquaculture, and on the electric, electronic and automobile industries (Begum et al, 2019;Chen et al, 2018;Gausepohl and Nießner, 2001;Gu et al, 2017).…”

Plastic pollution is one of the major issues impacting on the marine environment. Plastic polymers are known to leach industrial chemicals and associated contaminants. In this review, we focused on assessing the global distribution and concentration of two polystyrene-derived contaminants, hexabromocyclododecanes (HBCDs) and styrene oligomers (SOs), in marine sediments and seawater. Overall, most of the studies were carried out in Asia, North America, and Europe. Relatively high concentrations of these contaminants are generally attributed to the proximity of urban cities, plastic industries, polystyrene pollution, and aquaculture. Moreover, the concentrations in sediments are many times higher than in seawater. HBCDs were found to be a negligible risk to marine biota when compared to the ecotoxicological endpoints. However, realistic concentrations of SOs could compromise the wellbeing of certain species in highly polluted sites. The future perspectives and research were discussed.
