| Abstract | Cilj istraživanja: Ispitati koncentraciju metala i metaloida Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Hg, Li, Mg, Ni, Pb, Sb, Sr, U, V, Zn u tlu, vodi i maslačku, te mišićima, jetri i bubregu divljih životinja s područja Parka prirode Papuk, kao i serumu, urinu i kosi stanovnika rubnih dijelova Parka. Materijali i metode: Metodom ICP - MS ispitati po 31 uzorak tla i maslačka, 21 uzorak vode, po 52 uzorka mišića, jetre i bubrega divljih životinja, te po 101 uzorak urina, seruma i kose ispitanika. Rezultati: U uzorcima tla, vode i maslačka nisu ustanovljene povišene vrijednosti istraživanih elemenata, osim Zn u tlu, te Cd i Pb kod maslačka na južnoj strani Parka. Uzorci mišića divljači pokazali su povišene vrijednosti za Cd i Pb, a bubrega za Cu na cijelom području. As i Cd bili su povišeni i u mišićima, odnosno bubrezima jedinki iz Voćina i Čačinaca, dok su vrijednosti za jetru svugdje bile unutar maksimalno dopuštenih koncentracija. Povišene vrijednosti bile su u uzorcima urina ispitanika sa svih područja za Ba, Fe, U i Zn, još i za Cu i Sb sa sjevernog i južnog područja Parka, te za Cd s područja Humljana. Uzorci seruma sa svih područja pokazali su povišene vrijednosti za Ba, Cd, Co, Mg, U i V, dok su na području Voćina, Čačinaca i Velike bile povišene vrijednosti za Zn, na području Voćina, Humljana i Velike za Ni, te na području Humljana i Čačinaca za Fe. Uzorci kose svih ispitanika za sve elemente bili su unutar referentnih vrijednosti, osim za Fe s područja Čačinaca. Nisu ustanovljene statistički značajne razlike u opterećenju teškim metalima humanih uzoraka s obzirom na lokaciju, kao niti između onih koji konzumiraju divljač i onih koji to ne rade, odnosno između onih koji su učestalo u kontaktu s oružjem i streljivom u odnosu na one koji to nisu. Utvrđene vrijednosti ukazuju na potrebu dodatnih sveobuhvatnijih, kao i sličnih istraživanja na nekim drugim identičnim područjima. Zaključak: Konzumacija divljači, kao i kontakt s oružjem prilikom lova ne predstavlja izraziti rizični čimbenik za opterećenje teškim metalima, za razliku od ratnih aktivnosti. |
| Abstract (english) | Research goal: To examine the concentration of metal and metalloids Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Hg, Li, Mg, Ni, Pb, Sb, Sr, U, V and Zn in soil, water and dandelion from the entire Nature Park Papuk area, muscle, liver and kidney in wild animals from the same area, as well as serum, urine and hair of the population bordering the Nature Park Papuk area. Materials and methods: To examine with the ICP – MS method 31 soil and dandelion samples, 21 water samples, 52 muscle, liver and kidney samples from wild animals, as well as 101 urine, serum and hair samples from the population. Results: In soil, water and dandelion samples there mostly have not been established increased amounts in the studied elements, except Zn in soil and Cd and Pb in dandelion in the southern section in the examined area. Muscle samples in wild game have shown increased amounts of Cd and Pb, as well as Cu in the kidneys in the entire area. As and Cd were found increased in muscles and kidneys in the units in the Voćin and Čačinci area, while everywhere amounts in liver were within the maximum allowed concentration. Increased amounts were found in urine samples from the population in all areas with regards to Ba, Fe, U and Zn, as well as Cu and Sb from the northern and southern areas in the Nature Park, and also Cd from the Humljani. Serum samples from the population in all areas showcased increased amounts of Ba, Cd, Co, Mg, U and V, while in the Voćin, Čačinci and Velika there was an increase in Fe. Hair samples from the entire population for all elements were within the referent amounts, except Fe in the Čačinci. No statistically valuable differences have been established for heavy metal overload in human samples with regards to location, same as between those who consume wild game and those who do not, same as those who are frequently in contact with weapons and ammunition and those who are not. However, established amounts point to a need for further studies which would be more encompassing, as well as the need for similar studies in some other identical areas. Conclusion: According to the results, wild game consumption as well as contact with weapons during hunts do not showcase a risk factor for heavy metal overload as opposed to war activities. |
