Abstract
Akvatični organizmi predstavljaju vrlo značajan izvor bjelančevina i esencijalnih masnih kiselina u ljudskoj prehrani. Teški metali su veliki problem kao okolišna onečišćivala obzirom na njihova toksična, mutagena i karcinogena svojstva. Među najznačajnijima su: kadmij, olovo, živa, arsen. Hranidbena mreža predstavlja glavni put bioakumulacije teških metala u vodenim organizmima i rizik za zdravlje ljudi. U ovom radu ispitni materijal je škamp, dekapodni rak Nephrops norvegicus (Linnaeus,1758) izlovljen u tri različite ribolovne zone Europe (FAO 37.2, FAO 27, FAO 34). Arsen nije predmet Zakona o kontaminantima (NN 39/13) ali su njegove visoke koncentracije utvrđene u svim uzorcima. Usporedba dobivenih razina ostalih ispitivanih elemenata sugerira na zdrastvenu ispravnost uzoraka osim za živu u uzorku jedne lokacije FAO 37.2 (Jadransko more) gdje medijan (0,83 mg/kg) prelazi najveću dopuštenu količinu reguliranu europskom legislativom (EC/1881,2006). Prema preporuci Svijetske zdravstvene organizacie (WHO) dozvoljeni tjedni unos žive u ljudski organizam (PTWI) iznosi 0,05 mg/kg. Dobivenim podacima za živu konzumacijom unosimo 0,31 mg žive što je unutar dozvoljenih vrijednosti i ne predstavlja rizik za zdravlje ljudi.
Abstract (english)
Aquatic organisms are a very important source of protein and esential fatty acids in the human diet. Heavy metals are a major problem as environmental pollutants due to their toxic, mutagenic and carcinogenic properties. Among the most significant are: cadmium, lead, mercury, arsenic. The food chain is the main pathway for bioaccumulation of heavy metals in aquatic organisms but it also poses a risk to human health. In this experiment, the test material is the decapod crustacean Nephrops norvegicus (Linnaeus, 1758) fished in three different fishing zones in Europe (FAO 37.2, FAO 27, FAO 34). Arsenic is not subject to the Contaminants Act in Croatia (NN 39/13) but its high concentrations are found in all shrimp samples. Comparison of the obtained levels of the other elements tested suggests a health standard other than mercury in sample of FAO 37.2 (Adriatic sea) site whose median (0.83 mg/kg) exceeds the maximum permitted amount regulated by European legislation (EC/1881,2006). According to the World Health Organization recommendation (WHO) the allowable weekly intake of mercury into the human body (PTWI) is 0.05 mg/kg. According to the data obtained for live consumption, 0.31 mg of mercury is ingested, which is below the permitted levels. It does not pose a risk to human health.
