| Sažetak | Područje Labina bilo je više od dva stoljeća središte hrvatskog rudarstva, metaloprerađivačke industrije i proizvodnje električne energije na ugljen. Lokalni sumporom bogati Raški ugljen jedinstven je u svjetskim razmjerima u usporedbi s drugim vrstama ugljena zbog iznimno visokih vrijednosti organskog sumpora, do 11%. On je korišten u termoelektrani Plomin tijekom razdoblja 1970.-2000. Nakon toga je zamijenjen uvoznim niskosumpornim ugljenom. U ovom radu prikazane su razine S, Se, V, U, Hg, Sr, Cd, Cr, Pb, Cu i Zn u dva tipa ugljena, njihovih pepela, morske vode i biljnih (djetelina, gljive i lišće) uzoraka prikupljenih s područja grada Labina, dok su sulfat izmjeren u površinskoj vodi. Njihove su razine uspoređene s relevantnim zakonodavnim i objavljenim podacima s različitih svjetskih lokaliteta. Analiza podataka protumačena je u kontekstu prošlih i nedavnih aktivnosti izgaranja ugljena. |
| Sažetak (engleski) | The Labin city area has represented the major Croatian coal mining, metal industry, and coal-fired electricity centre for more than two centuries. The domestic superhigh-organic-sulphur (SHOS) Raša coal is a unique variety compared to other coal types worldwide, based on its highest organic sulphur values, up to 11%. It was utilised in the Plomin coal-fired power plant during the period 1970–2000.. Afterwards, it was replaced by an imported low-S coal. This thesis elaborates levels of S, Se, V, U, Hg, Sr, Cd, Cr, Pb, Cu, and Zn in two coal types, their bottom ash, seawater, and plant (clover, mushroom, and foliage) samples collected from the Labin City area, while the sulphate was measured in surface stream water. Their levels are compared with relevant legislative as well as the published data from different world localities. Data analysis was interpreted in the context of past and recent coal combustion activities. |
