“…Concentrations of OCPs in eggs were much higher than that in dropping-amended soils. This is consistent with the results from Wrichbrodt and Vetter [31] and demonstrates that POP can be transferred through the eggs to the offspring. …”

“…In the eggs of giant petrel, concentrations of ΣPCB ranged from 48.1 to 81.7 ng/g, ΣDDT 12.7 to 53.7 ng/g, ΣHCB 4.2 to 8.8 ng/g and ΣHCH 0.5 to 1.5 ng/g. Results from this study agreed well with those from the similar study by Weichbrodt for the average accumulation levels of ΣHCH, ΣDDT, and ΣPCB in Antarctic skua eggs [31] . Compared with aforementioned results, ΣPCB increased slightly.…”

Persistent organochlorine pollutants (POPs) are analyzed for the dropping-amended soils from the habitats of Antarctic seabirds and seals in Fildes Peninsula and ArdleyIsland. The concentration ranges are 0.21 to 3.85 ng/g for polychlorinated biphenyls (ΣPCBs), 0.09 to 2.01 ng/g for organochlorine pesticides (ΣDDT), and 0.06 to 0.76 ng/g for hexachlorocyclohexanes (HCHs). Among these, hepatachlorobiphenyls, hexachlorobiphenyls, p,p′-DDE and α-HCH compounds are dominant. The concentration ranges of ΣPCB, DDT and HCH in the eggs of skuas were 91.9-515.5 ng/g, 56.6-304.4 ng/g and 0.5-2.0 ng/g respectively; those in the eggs of penguins were 0.4-0.9 ng/g, 2.4-10.3 ng/g and 0.1-0.4 ng/g; and those in the eggs of giant petrel were 38.1-81.7 ng/g, 12.7-53.7 ng/g and 0.5-1.5 ng/g respectively. The dominant POP compounds in the eggs are PCB180, PCB153, p,p′-DDE and hexachlorobenzene (HCB). The present study shows that the concentration of POPs in the seabird-inhabited-dropping-amended soil varies with the extent of predation and nest occupancy of different seabird populations. Statistical analysis on the POP concentrations from the different seabird eggs implies that the difference in the bio-concentration levels of the birds depends on the bio-habits of the species, such as the range of activity, distance of immigration, feeding pattern, and nest occupation. Among these, the most important factor is the location of the seabirds in the food chain and their feeding pattern. This shows that POPs accumulated in the seabirds resulted from the bio-concentration through the food chain. In addtion, 210 Pb dating for the dropping-amended soils (AD1-a and AD2) was performed, which provided the POP accumulation rate and the historic record for the soil profile. It indicates that POP will continuously affect the Antarctic ecosystem for a long time.

“…1,2 High levels of Q1 (up to 120 mg/kg fresh weight) were also determined in eggs of Antarctic birds. 3 Furthermore, Q1 was highly abundant in human milk samples of women from the Faeroe Islands who had regularly consumed whale. 4 Q1 was detected in a fish sample from the Mediterranean sea, as well as harbor porpoises from Iceland.…”

Q1, a heptachloro component of unknown structure and origin, was recently identified as a major organochlorine contaminant in samples from Africa and the Antarctic. Gas chromatography in combination with low resolution mass spectrometry (LRMS) was applied to establish a molecular weight of m/z 384 including seven chlorine atoms. Three possible molecular formulae (C(11)H(7)Cl(7), C(10)H(3)Cl(7)O, and C(9)H(3)Cl(7)N(2)) were proposed which could not be distinguished by LRMS. In this presentation the molecular composition of Q1 was studied using gas chromatography in combination with high resolution electron impact ionization mass spectrometry. With the option of further heteroatoms (P, S, N, O, F, and Br), 17 molecular formulae were obtained for the molecular weight of 384 u. In the selected ion monitoring (SIM) mode, performed with a resolution of 16,000, highest response was found at 383.812 or C(9)H(3)Cl(7)N(2). 11 fragment ions detected in the low resolution full scan mass spectrum of Q1 were also investigated in the high resolution SIM mode. In every case, the nitrogen-variant showed highest abundance while the other 16 structural variants could be definitely excluded. These investigations revealed that the molecular formula of Q1 is C(9)H(3)Cl(7)N(2). No stable component with this molecular formula has ever been reported in the literature, to our knowledge.

“…These dark gull-like seabirds are predatory seabirds, which in the investigated area extensively feed on fish. The weights of the eggs were 93 g (sample 46x) and 85 g (sample 10b), and lipid contents were 7.0 and 5.8%, respectively [17]. Aliquots of the freeze-dried samples were extracted using focused-open vessel microwave-assisted extraction followed by gel-permeation chromatography, adsorption chromatography on deactivated silica [17].…”
