| Abstract | Morska riba je vrijedan izvor energije, visoko kvalitetnih proteina, vitamina, omega-3 masnih kiselina i esencijalnih elemenata. Ipak, konzumacijom ribe može se povećati i unos različitih toksikanata koje nakuplja iz okoliša, uključujući živu. Cilj ovog rada bio je ispitati navike konzumacije morske ribe u Hrvatskoj, odrediti sadržaj elemenata u mišićju najčešće konzumiranih pridnenih vrsta iz Jadranskog mora, te procjeniti korist i moguće rizike konzumacije ribe s obzirom na njen elementni sastav. Utvrđeno je da se najviše konzumira svježa riba iz divljeg ulova u Jadranskom moru, 1,4 puta tjedno. Prema vrstama, prosječni raspon koncentracija elemenata (mg/kg) bio je: K: 4523 - 4685; Mg: 335 - 342; Zn: 2,6 - 3,9; Fe: 0,89 - 2,3; Cu: 0,12 - 0,20; Se:0,19 - 0,45; Hg: 0,07 - 1,2. Arbuni su imali koncentracije žive veće od 1,0 mg/kg. Jedan obrok (150 g) brancina, orade, oslića i/ili trlje blatarice dobar je izvor selena (cca. 75 % DRV), a njegova tjedna konzumacija ne predstavlja rizik od štetnih učinka žive za zdravlje potrošača. |
| Abstract (english) | Marine fish is a valuable source of energy, high-quality proteins, vitamins, omega-3 fatty acids and essential elements. However, consumption of fish can increase the intake of various toxicants that are accumulated from the environment, including mercury. The aim of this work was to examine the consumption habits of sea fish in Croatia, to determine the content of elements in the muscles of the most commonly consumed demersal species from the Adriatic Sea, and to assess the benefits and possible risks of fish consumption with regard to its elemental composition. It was established that the most consumed was fresh fish from the wild catch in the Adriatic Sea, 1,4 times a week. According to species, the average range of element concentrations (mg/kg) was K: 4523 - 4685; Mg: 335 - 342; Zn: 2.6 - 3.9; Fe: 0.89 - 2.3; Cu: 0.12 - 0.20; Se: 0.19 - 0.45; Hg: 0.07 - 1.2. Arbuns had mercury concentrations higher than 1.0 mg/kg. One serving (150 g) of sea bass, sea bream, hake and/or red mullet is a good source of selenium (ca. 75 % DRV), and its weekly consumption does not pose a risk of harmful effects of mercury for the health of the consumer. |
