“…In the Neretva River delta, situated at the shore part of Croatia, there is intensive agricultural production, possibly explaining the offshore source and transport of contaminants from the past presumably when OC pesticides were still in use. Similarly, the Kaštela Bay (Split) in the middle Adriatic included a chlor‐alkali industrial unit up until the 1990s Picer (). Thus this might be responsible for the HCB, heptachlor and heptachlor epoxide, detected in industrial OC concentrations.…”

SummaryThis work examines the bioaccumulated organochlorine compounds in Muraena helena to draw attention to this species as a potential bioindicator organism. The morays were caught in the East Adriatic Sea, Elaphite Islands, near Dubrovnik, Croatia (lat: 42°45′38.8″; long: 17°45′53.6″) at the same location in summer (August, 2009) and winter (January, 2010), at depths from 5 to 10 m. Nine fish were caught by longline hooks per each field trip (total in summer and winter, N = 18). No single fish was free of organochlorines (OC), but not all pesticides were present in every fish. The concentration level was: Endrin > ppDDE > Heptachlor epoxide > Heptachlor > Aldrine > Lindane > bHCH > dHCH > Endrin aldehyde). Endrin was the only pesticide approaching the maximum concentrations proposed by the European Union and Croatia (summer max. concentration = 14.75 lg kg À1 ; winter max. concentration = 8.35 lg kg À1). All other pesticides ranged from 0.1 to 0.7 lg kg À1. Heptachlor was absent in winter and d-HCH and Endrin aldehyde in summer, while Lindane and pp-DDE had higher (P ≤ 0.05) concentrations in summer. Other residues had similar seasonal concentration levels. The p-DDT was similar as in other biota from the Adriatic or Mediterranean. HCH concentrations corresponded to those found in organisms from the Italian area of the Adriatic. The endocrine and reproductive disrupting potential of the detected OCs are bases for future studies. Results show that morays are a good bioindicator model, with slight interspecies and seasonal variability in OC bioaccumulation as a consequence of diverse food consumption.

Contaminated soil was taken from the area around the damaged capacitor of an electrical transformer station in Zadar (Croatia) and a phytoremediation experimental field was constructed with lysimeters. The levels of PCBs in the leachate water samples were measured nearly 3 years. The experiment was conducted under natural climatic conditions, through hot summers and mild winters. Although the amounts of leachated PCBs from the polluted soil were relatively small, their concentrations in leachate water samples from 1,500 to 29,000 ng L(-1) substantially exceeded the maximum allowed concentration of the total PCBs in the fishponds of Croatia (1 ng L(-1)).

“…Some compounds have a strong tendency to bind to suspended particles; marine sediments have often been considered as the ultimate sink for nonpolar compounds (Salomons and Förstner, 1984). The relatively high lipophilic characteristic of OCs induces their accumulation in organisms and adsorption on suspended particles.…”
