Abstract

U tkivima kitova zubana iz Jadranskoga mora (mišićno tkivo, jetra, bubreg, pluća, slezena, masno tkivo i koža) određene su koncentracije arsena, kadmija, olova, žive i selena. Obrađeno je 186 dupina, od toga 25 plavobijelih, 6 glavatih i 155 dobrih dupina. Koncentracije metala određivane su grafitnom tehnikom na atomskom apsorpcijskom spektrometru, tehnikom stvaranja hidrida na atomskom apsorpcijskom spektrometru i induktivno spregnutoj plazmi-optičkoj emisijskoj spektrometriji. Budući da mnoge vrste morskih sisavaca dijele obalno okruženje s ljudima i konzumiraju istu morsku hranu (ribe i glavonošce), oni mogu poslužiti kao učinkoviti indikatori za javnozdravstvene probleme. Ovaj pristup osigurava novi put za bolje razumijevanje povezanosti ekosustava i zdravlja ljudi.

Abstract (english)

In tissues of toothed whales from the Adriatic Sea (muscle, liver, kidney, lung, spleen, adipose tissue and skin) the concentrations of arsenic, cadmium, lead, mercury and selenium were analyzed. A number of processed dolphins were 186, 25 of which are striped, 6 Risso's and 155 bottlenose dolphins. Concentrations of heavy metals were determined by graphite furnace atomic absorption spectrometer, flow injection mercury system and inductively coupled plasma atomic emission spectroscopy. Since many species of marine mammals share the coastal environment with humans and consume the same seafood (fish and cephalopods), they can serve as effective indicators of public health issues. This approach provides a new way for better understanding of the relationship between ecosystems and human health.
