Porazdelitev kemičnih prvin v bivanjskem prahu, cestnem sedimentu in tleh na območju Celja : diplomsko delo = distribution of chemical elements in dwelling dust, street dust and soil in Celje : diploma thesisVrabič, KatjaDiplomska naloga je bila opravljena na Geološkem zavodu Slovenije (Oddelek za geokemijo in geologijo okolja) v okviru raziskovalnega projekta Monitoring lokalnega onesnaženja zraka v Celju v letu ... 2005. Namen diplomske naloge je bila določitev koncentracije težkih kovin v različnih prahovih in tleh. Vzorčila sem na območju Celja in v bližnji okolici Cinkarne Celje ter Železarne Štore. Vzorce sem pobrala na E in W strani vsakega onesnaževalca glede na smer vetra. Vključena so bila območja Delavske, Teharske ulice, Bukovžlaka, Štor, Lave in Nove Cerkve. Odvzetih je bilo 31 vzorcev različnih sedimentov (podstrešni prah, hišni prah, cestni sediment, zgornji in spodnji sloj tal). V preiskovanih vzorčnih medijih so bile ugotovljene vsebnosti 36 kemičnih prvin (Al, Ca, Fe, K, Mg, Na, P, S, Ti, Ag, As, Au, B, Ba, Bi, Cd, Co, Cr, Cu, Hg, Ga, La, Mn, Mo, Ni, Pb, Sb, Sc, Se, Sr, Th, TI, U, V, W in Zn). V nalogi sem se osredotočila na določitev recentne emisije težkih kovin v zrak, zaradi delovanja kemične industrije ter železarske dejavnosti na območju Celja in Štor. Na podlagi kemijske analitike sem ugotovila onesnaženost okolja s težkimi kovinami. Na območju Delavske in Bukovžlaka sem v tleh in prahovih zabeležila največjo onesnaženost s težkimi kovinami, kot so As, Cd, Pb in Zn. Najnižje koncentracije težkih kovin pa so bile zabeležene v Novi Cerkvi. S faktorjem obogatitve, smo ugotovili naraven ali antropogen izvor kemične prvine med prahovi in tlemi ter med referenčno točko in ostalimi vzorčnimi točkami. Kot referenčno prvino sem si izbrala Al. Geokemične lastnosti prahov in tal na onesnaženih lokacijah (Delavska, Teharska ulica, Lava, Bukovžlak in Štore), sem primerjala s prahovi in tlemi na referenčni točki Nova Cerkev, ki dokazano leži izven vpliva celjskih onesnaževalcev. Ugotovila sem, da so porazdelitve Al, Ca, K, La, Mg, Sc, Th in Na, odvisne predvsem od naravne geološke porazdelitve. Za kemične prvine Cd, Pb, Zn, As, Fe, Co, Cr, Ni, Mn, Ti in Hg pa sem ugotovila, da je njihov izvor predvsem posledica delovanja Cinkarne Celje in Železarne Štore.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [K.
