Research paper thumbnail of Persistent Organic Pollutants (POP in) in Southern Ocean seabirds: spatial and accumulation patterns among POP families and species

Several studies have demonstrated the presence of Persistent Organic Pollutants (POPs) in Antarct... more Several studies have demonstrated the presence of Persistent Organic Pollutants (POPs) in Antarctic wildlife and in some cases some adverse effects due to POP exposure have been described1. In spite of the efforts made during the last two decades to address the presence of POPs in Antarctic predators, data arescarce, especially in the case of emerging POPs.Moststudies are limited toa few sampling pointsandspeciesand mostly to legacy POPs2.Accordingly, the influence of key factors driving the exposure to POPs and related compoundsin Antarctic predators, i.e. trophic relationships and geographic distribution or movements, remains unclear1,2. In this study we aimed toevaluate the relative influence of spatialdistributionand trophic ecologyof Antarctic wildlife in their exposure to POPs and related compounds. For that, 45 chemicals were analyzed in plasmaof 206 seabirds belonging to 8species. Organochlorinated pesticides (6 DDTs and HCB), chlorinated and brominated flame retardants (2 DPs and 15 PBDEs, respectively), polychlorinated biphenyls (7 indicator PCBs) and perfluoralkylated substances (15 PFASs: Five perfluoroalkanesulfonates (PFSAs, C4-12), ten perfluoroalkyl carboxylic acids (PFCAs, C4-13) and perfluorooctane sulfonamide (FOSA)were studied. Moreover, stable isotope ratios of C and N (δ13Cand δ15N) were also determined in plasma and used to infer the potentiallatitude offoraging areas and trophic position, respectively2

Research paper thumbnail of Suitability of several carbon sorbents for the fractionation of various sub-groups of toxic polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans

Journal of Chromatography A, May 1, 2001

Feasibility of several sorbents, Amoco PX-21, Carbosphere, Carbopack B and C and 2-(1-pyrenyl) et... more Feasibility of several sorbents, Amoco PX-21, Carbosphere, Carbopack B and C and 2-(1-pyrenyl) ethyldimethylsilylated silica gel (PYE), for the fractionation of polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins and furans was investigated. Selection was based on their suitability for quantitative isolation of the target compounds with special attention for the most toxic mono- and non-ortho-CBs to prevent coelution with other congeners during the final determination by gas chromatography. Cost-effectiveness in terms of solvent and time consumption as well as feasibility for routine analysis and automation were considered additional merits of the methods compared. Final evaluation of the procedures providing the best results was done by comparison of the results obtained from the analysis of real-life samples. The results showed that, among the sorbents tested, Carbopack B and PYE were the most suitable for routine analysis. In particular, these sorbents allowed a more reliable determination of the toxic congeners and, consequently, of the toxic equivalents of 2,3,7,8-tetrachlorodibenzo-p-dioxin content in environmental samples.
