“…Recently, several POPs have also been implicated as lipid disruptors in humans and rodents 25,26 . In fish and zooplankton, POPs can increase fat deposition and lipogenic gene expression [27][28][29][30][31] . Conversely, exposure to POPs such as dioxins, lindane and OCPs can cause rapid energy reserve depletion, termed 'wasting syndrome' [32][33][34][35] .…”

Persistent organic pollutants (POPs) are toxic, ubiquitous, resist breakdown, bioaccumulate in living tissue and biomagnify in food webs. POPs can also alter energy balance in humans and wildlife. Marine mammals experience high POP concentrations, but consequences for their tissue metabolic characteristics are unknown. We used blubber explants from wild, grey seal (Halichoerus grypus) pups to examine impacts of intrinsic tissue POP burden and acute experimental POP exposure on adipose metabolic characteristics. Glucose use, lactate production and lipolytic rate differed between matched inner and outer blubber explants from the same individuals and between feeding and natural fasting. Glucose use decreased with blubber dioxin-like PCBs (DL-PCB) and increased with acute experimental POP exposure. Lactate production increased with DL-PCBs during feeding, but decreased with DL-PCBs during fasting. Lipolytic rate increased with blubber dichlorodiphenyltrichloroethane (DDT) and its metabolites (DDX) in fasting animals, but declined with DDX when animals were feeding. Our data show that POP burdens are high enough in seal pups to alter adipose function early in life, when fat deposition and mobilisation are vital. Such POP-induced alterations to adipose glucose use may significantly alter energy balance regulation in marine top predators with the potential for long term impacts on fitness and survival.

“…As in the previous results, this supports the notion that the polar features could be very similar to PCBs found in fish tissue. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Moreover, the ice-cold condition was strongly suggested to remove the heat disturbance.…”

“…Aiming at improving the fish and aquatic invertebrates sample pretreatment process, a series of sample preparation techniques are carried out, which were developed by modifying the Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method published in 2003. [5][6][7][8][9][10][11] To overcome the limitation of the QuEChERS method, dispersive solid phase extraction (d-SPE) methods were strongly recommended and widely accepted, and were applied to the detection of PCBs, OCPs or other POPs organic compound multi-residues in animal origin foods, as well as fish and even water samples, shown as Table 1.…”

Optimized Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) pretreatment methods for determination of six polychlorinated biphenyls (PCBs) residues in fish and aquatic invertebrates samples were investigated. Large volume injection (LVI) coupled gas chromatography tandem mass spectrometry (GC-MS/MS) with selected reaction monitoring (SRM) was used to provide a very sensitive and selective means of analyzing PCBs via internal calibration. Three analytical processes were validated and compared, and the florisil Celite ® 545 pretreatment method was selected. Performance characteristics, such as linearity, limit of detection (LOD), limit of quantization (LOQ), recovery and precision (relative standard deviation, RSD) were studied. The method was applied to 233 samples obtained from local markets, which was useful and thus suggested that the method could serve as a screening model for PCB residues analysis.

“…A third channel connects Ganzirri lake to Faro lake, which in turn is connected to the Tyrrhenian and Ionian Sea. This geographic arrangement allows a constant sea water circulation so that both the water and the fishes are not contaminated by inorganic and organic substances (Dugo et al 2010;Lo Turco et al 2013;Di Bella et al 2015;Naccari et al 2015;Maisano et al 2016;Saija et al 2016). Moreover, this channel system allowed the formation of a micro unique ecosystem that consents to certain plant and animal species to live here only (Crescenti et al 2010;Coppari et al 2016).…”

Considering the crucial role of carotenoids exploitable both as nutraceuticals and also as dyes in food industry, there are many efforts in seeking for new sources of these pigments, especially in the marine world. In this study, for the first time, we extracted carotenoids from sea sponges Raspaciona aculeata and Dictyonella marsilii taken from Ganzirri Lake Messina (Italy). The determination and quantification of carotenoids was made by UPLC-PDA-MS. Remarkable results concern renieratene content in R. aculeate found to be over 2570 ppm.
