Opis:: In this study, the total mercury concentration was determined in the muscles, liver and gills of six fish species (rainbow trout Oncorhynchus mykiss Walb., carp Cyprinus carpio L., bream Abramis brama L., perch Perca fluviatilis L., ide Leuciscus idus L. and flounder Platichthys flesus L.). The fish were acquired from October to November 2012. Mercury was analyzed by atomic absorption spectrometry using thermal decomposition, compounds of mercury and amalgamation. The mercury content in fish organs reached 0.006-0.168 (in mg kgˉ¹ wet weight) in muscles, 0.001-0.027 in gills and 0.003-0.045 in the liver. The muscles of perch and ide had significantly more Hg compared to the other fish’s muscles (P≤0.05). The liver and gills of perch, ide and flounder contained more Hg than the same tissues of the other fish (P≤0.05). Generally, the highest Hg content was determined in muscles (except rainbow trout) (P≤0.05), whereas the lowest Hg content was found in gills (except perch) (P≤0.05). The content of Hg in gills of perch did not differ from the one in the liver (P>0.05). There was a positive correlation between the weight or length of a fish and the Hg concentration in its tissues, except for the length and Hg in the gills of carp. However, a statistically significant positive correlation between the body weight and the Hg levels in fish appeared only in the case of the organs of ide (P≤0.004) and muscles of carp (P≤0.038). The correlation between the factor condition and the content of Hg, albeit positive (0.106 < r < 0.811) except for the organs of flounder, was not statistically significant (P>0.05).

Opis:: The paper evaluates the effect of culture conditions and culture site on levels of certain microelements (Zn, Cu, Fe) and macroelements (Mg, Ca) in three species of freshwater fish: rainbow trout (Oncorhynchus mykiss Walbaum), common carp (Cyprinus carpio L.), and Siberian sturgeon (Acipenser baeri Brandt). The study involved 90 individuals of freshwater fish aged from 6 to 12 months. Samples of blood, liver, kidney, gills, skin and muscles were collected from each fish and subjected to chemical assay of Mg, Ca, Zn, Cu, Fe with inductively coupled plasma-atomic emission spectrometry in a JY-24 Jobin Yvon apparatus. The study revealed that culture site had statistically significant impact on levels of the examined elements among the three fish species. Mg content in kidney and skin was significantly higher in carp than in sturgeon. Similar regularities were observed for Ca content in skin and Zn content in kidney. Liver and kidney levels of Fe and Cu were significantly lower in carp than in rainbow trout. Of all the three examined fish species, rainbow trout had the highest skin levels of Ca and Mg, and the highest blood level of Fe. The results indicate that culture site and culture conditions exerted significant influence on levels of macro- and microelements in freshwater fish.
Celem pracy była ocena wpływu warunków i miejsca prowadzenia hodowli na zawartość mikroelementów (Zn, Cu, Fe) i makroelementów (Mg, Ca) w organizmach ryb słodkowodnych. Ocenie poddano trzy wybrane gatunki ryb: pstrąga tęczowego (Oncorhynchus mykiss Walbaum), karpia (Cyprinus carpio L.) i jesiotra syberyjskiego (Acipenser baeri Brandt). Badaniu poddano 90 ryb słodkowodnych w okresie od 6. do 12. miesiąca życia. Z każdej ryby do analiz chemicznych pobrano próbki: krwi, wątroby, nerek, skrzeli, skóry i mięśni. Próbki poddano analizie na zawartość Mg, Ca, Zn, Cu, Fe, z użyciem emisyjnej spektrometrii atomowej w plazmie indukcyjnie sprzężonej (ICP-AES), w aparacie Jobin Yvon typ JY-24. Wykazano, że miejsce hodowli ma statystycznie istotny wpływ na zawartości badanych pierwiastków u poszczególnych gatunków ryb słodkowodnych. Zawartość Mg w nerce i skórze karpi była istotnie wyższa niż u jesiotra. Podobne spostrzeżenia dotyczyły poziomu Ca w skórze i Zn w nerce. W przypadku Fe i Cu obserwowano niższą zawartość w wątrobie i nerkach karpi niż w tych samych narządach u pstrąga. Badania wykazały, że poziom Zn i Cu we wszystkich narządach przebadanych gatunków kształtował się na najniższym poziomie. Spośród badanych gatunków u pstrąga stwierdzono najwyższą zawartość Ca i Mg w skórze, a Fe we krwi. Otrzymane wyniki pozwalają stwierdził, że miejsce i warunki prowadzenia hodowli mają istotny wpływ na zawartość badanych makro- i mikroelementów w organizmach ryb słodkowodnych.

Opis:: Previous studies in the Gulf of Gdańsk discussed the responses of selected enzymatic biomarkers to the contaminant gradient in fish and mussels. In the present study, flounder muscle and liver tissues were analyzed for polychlorinated biphenyls (PCB congeners: 28, 52, 101, 118, 138, 153 and 180), organochlorine pesticides (HCHs, HCB and DDTs), and trace metals (Pb, Cd, Zn, Cu, Hg, Cr). An attempt was made to identify the relationship between the measured enzymatic biomarker responses (cholinesterases, malic enzyme, isocitrate dehydrogenase, glutathione S-transferase) and contaminant concentrations in selected flounder tissues. The observed differences in enzymatic biomarker levels suggest that chronic exposure to low-concentration mixtures of contaminants may be occurring in the studied area. However, no conclusive evidence was found of a clear link between the biomarker responses and contaminant concentrations in flounder tissues.
