The aim of this study was to assess the accumulation and seasonal variations of 20 toxic and trace elements in the abdominal and dorsal muscle (DM), liver and gut contents (GCs) of Cyprinus carpio, and in the sediments and zooplankton from semi-intensive aquaculture ponds during a six-month production season (from May to October). Sediments showed the highest concentrations of the measured elements, followed by zooplankton, fish GCs and livers, while the lowest levels were present in fish muscles. Correspondence analysis revealed that the elemental composition of the fish GCs was mostly similar to that of the sediment and zooplankton. The element concentrations of carp liver and muscles were more similar to each other. Overall, the results indicate that fish liver was the main target organ accumulating Cu, Se and Zn, regardless of their initial amounts in the environment. A seasonal decrease of a range of elements in fish liver (Al, Co, Fe, Li, Mn, Ni, Pb and Sr) was evident towards the end of the investigation period. In addition, the fish DM showed a seasonal accumulation of Sr and Li. However, toxic elements i.e. As, B, Ba Hg and V did not show such a seasonal variation, and were evenly distributed between fish liver and muscles. The concentrations of some elements, such as As, in fish tissues were similar or even higher than in literature data from polluted sites, but none of them exceeded the maximum acceptable concentrations prescribed by Serbian legislation or by FAO or EU regulation.

1 Seasonality of poisonings was studied among 28 692 cases reported during the years 1980-1982 in Finland with special reference to recurring peak months over years. Poisonings predominated in the summer. For all age-groups peaks of envenomations, plant poisonings and pesticide poisonings recurred between June and September. 2 Among children aged 0-6 years, there were in addition recurrent peaks in poisonings by tobacco between June and August, by corrosive agents in September and by vitamins, trace elements and external medicines in October. Among children aged 7-15 years, fertilizer poisonings peaked recurrently in August. Among adults, poisonings by petroleum products peaked recurrently in July and December, psychopharmacologic drugs in July and October, paints, glues and plastics in November, alcohols in December and antimicrobial drugs in August and October. 3 Of all poisonings, 33% occurred in July, August or September in contrast to the expected 25%. Preventive efforts should thus be intensified during the summer.
