Istraživanje sadržaja teških metala u opekarskim proizvodima na bazi glina i sekundarnih sirovina

Abstract

Teški metali spadaju u najopasnije zagađujuće supstance životne sredine. Usled razvoja industrije dolazi do nekontrolisane emisije metala u atmosferu i hidorsferu, kao i kasnije akumulacije u sedimentima i zemljištu. Cilj ovog istraživanja je utvrđivanje ukupnog sadržaja teških metala u laboratorijskim uzorcima sa dodatkom sekundarnih sirovina i u proizvodima iz 12 ciglana u Srbiji. Određivan je ukupni sadržaj Cr, Cu, Ni, Mo, Zn, Co, Cd, Sb, Hg, As i Pb, kao indikator mogućnosti izluživanja u okolinu dejstvom atmosferilija.

Heavy metals are one of the most harmful substances to the environment. Industry revolution caused uncontrolled emission of metals to the atmosphere and hydrosphere with later accumulation in sediments and soil. The aim of this research was to determine heavy metals total content in laboratory samples with the addition of secondary raw materials as well as in clay brick products sampled from 12 masonry factories in Serbia. Total content of Cr, Cu, Ni, Mo, Zn, Co, Cd, Sb, Hg, As and Pb is estimated, as an useful potential leaching possibility indicator under atmospheric effect.
