“…The Sava River flows through agricultural areas, and the burden accumulated on its course has resulted in contamination of the Sava River fish with DDT, HCH, lindane, endrin and heptachlor with epoxide. This is also expected in countries with highly developed agriculture, as demonstrated by the analyses performed not only in edible fish tissue but also in some specific fish organs (9,(23)(24)(25). These reports, although occasionally exceeding the values recorded in our study, clearly confirm the existence of organochlorine pesticide accumulation in fish tissue.…”

Organochlorine Pesticides in Freshwater Fish from the Zagreb AreaThe aim of this study was to determine the level of organochlorine pesticides in freshwater fish from the Zagreb area, Croatia. The study included 215 freshwater fish samples from three sites: the Sava River, Lake Jarun, and five fishponds from the Zagreb surroundings. Organochlorine pesticides DDT and derivates, HCH, HCB, lindane, aldrin, dieldrin, endrin, heptachlor with epoxide, and methoxychlor were determined using the GC-ECD method. The determined amounts of organochlorine pesticides were within allowed concentration limits in all analysed fish samples. Median values ranged from below the detection limit of 0.01 μg kg-1 for dieldrin and metoxychlor to 2.00 μg kg-1 for DDT in the Cyprinidae fish family from the Sava River, Zagreb sampling site (group 1).This study has confirmed pesticide persistence in the overall ecosystem in our country despite the ban of some thirty years ago, like in many other parts of the world.

“…Aqueous flora accumulates pesticides in an attempt to eliminate them from the water, thus initiating the first step of bioaccumulation (9). The grade of bioaccumulation can be expressed as a factor of bioaccumulation representing the ratio of a substance concentration in a living organism and its concentration in the medium or food.…”

“…The increase of lipid soluble and persistent compounds with trophic level and comparable levels of more water soluble compounds, is in accordance with earlier studies of bioaccumulation in aquatic organisms with low trophic positions (e.g. JoaquimJusto et al 1995, Kaag et al 1997, Zaranko et al 1997, Russell et al 1999.…”

Concentration and transport of organic pollutants by Arctic sea ice may expose iceassociated fauna to high contaminant concentrations relative to pelagic organisms. Zooplankton and ice-associated amphipods were collected in the marginal ice zone near Svalbard to investigate whether habitat, diet and geographic sampling site influenced their organochlorine burden. Organochlorine concentrations were low in both zooplankton (Calanus hyperboreus, Thysanoessa inermis, Parathemisto libellula, Chaetognatha) and ice-associated amphipods (Apherusa glacialis, Gammarus wilkitzkii, Onisimus spp.), from 0.3 ng g -1 lipid weight trans-chlordane in A. glacialis to 36.9 ng g -1 lipid weight hexachlorobenzene (HCB) in G. wilkitzkii. Diet accounted for most of the explained organochlorine variance, followed by habitat and geographic sampling site. The concentrations were higher in carnivores (P. libellula, Chaetognatha, G. wilkitzkii, Onisimus spp.) than in herbivores (C. hyperboreus, T. inermis, A. glacialis). In comparison with zooplankton, ice fauna had high levels of organochlorines with high residence time in surface layers (hexachlorocyclohexane [HCH] and HCB), whereas compounds with higher particle affinity did not differ between habitats. This was attributed to the sea ice serving as a habitat that keeps ice fauna in the surface layer, rather than to the release of contaminants from the sea ice itself. HCHs were the only compounds that differed geographically. Higher α-/γ-HCH ratios in C. hyperboreus and A. glacialis from the Greenland Sea relative to North of Svalbard, are consistent with the geographic patterns in HCH levels reported for air, water, ringed seals Phoca hispida and polar bears Ursus maritimus.

“…The studies on biomagnification and food chain bioaccumulation of POPs in aquatic environments have predominantly been focused on predatory pelagic fish or mammals in lakes and marine environments. Benthic food webs including the base and lower trophic levels, and in particular those in lotic environments, have thus far been largely neglected, with a few exceptions (Galassi et al 1994;Hill and Napolitano 1997;Zaranko et al 1997).…”

Abstract:We investigated how the degree of autotrophy/heterotrophy and organism trophic position influenced the bioaccumulation of polychlorinated biphenyls (PCBs) in 10 benthic river food webs consisting of terrestrial detritus, periphyton, invertebrates, and age-0 brown trout (Salmo trutta) in southern Sweden. Concentrations of PCBs increased with trophic position, estimated from δ 15 N and δ 13 C, on a dry weight basis (ng·g -1 dry weight) but not on a lipid weight basis (ng·g -1 lipid). PCB biomagnification factors between the first and second trophic levels (invertebrates/ periphyton and invertebrates/detritus) ranged between 0.3 and 2.3 and between the second and third levels (trout/invertebrates) between 0.3 and 2.0 on a lipid weight basis. The mean proportion of carbon ultimately derived from terrestrial sources, α, was 0.82 ± 0.19 for invertebrates and 0.67 ± 0.28 for trout. Contrary to our hypothesis, PCB concentrations in trout were positively related to α (r 2 = 0.58-0.77, p < 0.05). As α and the periphyton density (g Cqm -2 ) in the rivers was positively related (r 2 = 0.88, p < 0.01), we propose that this relationship was due to an increased retention and exposure of PCBs to trout in rivers with low grazing pressure and high periphyton density.
