“…PAH concentration in sub-surface seawater samples from Alexandria's Mediterranean coast ranged between 13 and 120 ng/l [10]. Similar values (30-50 ng/l) were found in coastal water samples of the Gulf of Gdansk (Southern Baltic) [11], which are higher than the data (2-7 ng/l) obtained between 1992 and 1998, in 313 surface and deep seawater samples collected in the Baltic Sea [12]. There is very little data on the presence of POPs in the Antarctic seas.…”

The most significant findings on the presence of persistent organic pollutants (POPs) in the marine ecosystem at Ross Sea are presented. Seawater samples were collected in many sampling sites located in a large area of the Ross Sea during various Italian expeditions in Antarctica. Two classes of POPs were considered, namely polychlorobiphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs). The results highlighted the presence of these compounds in seawater samples at a total concentration level of about 50 pg/l for PCBs, and 220 pg/l for PAHs. Moreover, seawater samples showed low to high molecular weight PAHs (LMW/HMW) and phenanthrene to anthracene (PHE/ANT) ratios higher than 1 and 5, respectively, which may suggest the predominance of a petrogenic source (i.e. petroleum product contamination). Results were also obtained on the POP depth profile in the water column at Cape Adere, where two water masses converge and mix, i.e. the Modified Circumpolar Deep Water (MCDW) and the High Salinity Shelf Water (HSSW). According to both the PAH and temperature profiles a two-fold higher PAH and PCB concentration was observed for MCDW samples with respect to HSSW. This result represents the first experimental evidence of the external input of pollutants in this area of the Ross Sea coming from the outer oceanic circulation.

“…Residues of all chlorophenol isomers have been found in fresh and marine waters (WHO 1989) including coastal sea waters (Dimou et al 2006;Kot-Wasik et al 2004). The pollution of coastal sea waters by chlorophenols could modify the biota of this environment because these compounds have high toxicity, are recalcitrant, and are accumulated in sediments or at different levels in the trophic chain (Fleming 1995).…”

Removal of p-chlorophenol by the marine microalga Tetraselmis marina

et al. 2007

The ability of Tetraselmis marina, a green coastal microalga, to remove chlorophenols under photoautotrophic conditions was investigated. T.marina was able to grow in the presence of 20 mg L −1 of the phenolic compounds tested. The EC 50 (growth rate) value of p-chlorophenol (p-CP) to T.marina was found to be 25.5 mg L −1 . The microalga was able to remove chlorophenols, showing higher efficiency for p-CP. The effect of photoregime and NaHCO 3 concentration on p-CP removal was investigated. Under continuous illumination with 1 g L −1 NaHCO 3 initial concentration T.marina removed 65% of 20 mg L −1 in a 10-day cultivation period.

“…Rivers also bring residues of chlorinated pesticides into the Gulf of Gdańsk. The organochlorine halides, which are brought into the gulf, are present in suspensions and marine sediment, as well as in organisms living in the Baltic (Falandysz, Strandberg 2004;Kot-Wasik et al 2004;Sapota 2006;HELCOM 2010).…”

The aim of this study was to estimate the residue of chlorinated pesticides in the edible fish caught in the Gulf of Gdańsk and in the Vistula Lagoon. The highest mean concentrations of total DDT were found in the muscles of salmon (331.45 ng g -1 lw.) and sabre carp (306.29 ng g -1 lw.) caught in the Vistula Lagoon, and in the muscles of cod (309.88 ng g -1 lw.) and herring (304.86 ng g -1 lw.) from the Gulf of Gdańsk. Moreover, it was discovered that the following were present in the muscles of fish: DDT metabolites (pp'-DDE and pp'-DDD isomers) as well as hexachlorobenzene and its metabolites and endrin, dieldrin, α-endosulfan isomers and methoxychlor. Pesticides concentrations were higher in the livers of fish than in the muscles, which proves that the removal of toxins from the fish systems dominates over their accumulation. Because no concentration limits for pesticides have been defined, consumer safety assessment of fish caught in the Southern Baltic and in the Vistula Lagoon is not possible. The authors, having
