Abstract
Ovim radom istražile su se razine olova, stroncija, kalcija i cinka u 41 bedrenoj kosti smeđeg medvjeda (Ursus arctos Linnaeus, 1758) s područja Like i Gorskog kotara prikupljenih tijekom 2014 i 2015. godine. Metali su izmjereni tehnikom masene spektrometrije induktivno spregnute plazme. Ispitan je utjecaj spola i dobi na razine metala u kosti te nisu pronađene razlike u sadržaju metala između mužjaka i ženki, no uočen je proporcionalan rast dobi i razine elemenata. Istraživanjem razlika u sadržaju metala morfološki različite kompaktne i spužvaste kosti uočena je značajno veća razina u kompaktnom tipu kosti u odnosu na spužvasti tip bedrene kosti. Važan faktor koji utječe na razinu metala je i pozicija na kosti. Spužvasta kost, gdje su oba istraživana metala (olovo i stroncij) pokazala povezanost s esencijalnim elementima kosti (kalcij i cink), pokazala se relevantnijom za istraživanje interakcija između elemenata u bedrenoj kosti za razliku od kompaktne kosti. Izmjerena razina olova bila je istog reda veličine kao i kod divljih životinja u drugim zemljama te u rasponu normalnih razina za domaće životinje.
Abstract (english)
This study investigated the levels of lead, strontium, calcium and zinc in the femoral bone of 41 brown bears (Ursus arctos Linnaeus, 1758) from the area of Lika and Gorski kotar, collected during 2014 and 2015. Metal levels were measured by the inductively coupled plasma-mass spectrometry technique. Influence of gender and age was studied and no differences in metal content between males and females were found, while age was associated with levels of all elements. Differences in metal content in morphologically different compact and spongy bone have shown significantly higher levels of the elements in the compact type of the bone, compared to the spongy bone. Location of bone sampling was also proven to be an important factor for metal levels. It was observed that spongy bone type, where both investigated metals (lead and strontium) were associated with the essential bone elements (calcium and zinc), is more relevant for investigation of interactions between the elements. The measured levels of lead were of the same order of magnitude as in wild animals from other countries and in the range of normal levels for domestic animals.
