Abstract

U ovom radu dan je prikaz oneĉišćenja tla teškim metalima uzrokovanog privremenim
odlaganjem čeličnog otpada na nezaštićenim zemljanim površinama. Čelični otpad se koristi
kao sirovina za proizvodnju čelika. Kao primjer ovakve vrste onečišćenja tla, dan je osvrt na
ispitivanje tla provedenog na podruĉju tzv. lomare u sisaĉkoj čeličani. Na tom području se
čelični otpad odlagao dugi niz godina te je bio izloţen utjecaju atmosferilija što je dovelo do
onečišćenja tla. U navedenom ispitivanju, analizirane su koncentracije teških metala u tlu (Cd,
Cr, Cu, Hg, Ni, Pb i Zn). Dobiveni rezultati analize uzoraka tla sa područja lomare uspoređeni
su s rezultatima referentnog uzorka tla, kao i s preporučenim graničnim vrijednostima teških
metala u tlu namijenjenog u industrijske i komercijalne svrhe prema Programu trajnog
motrenja tala Hrvatske i graničnim vrijednostima teških metala u tlu propisanih Pravilnikom o
zaštiti poljoprivrednog zemljišta od onečišćenja.

Abstract (english)

This paper reviews soil contamination with heavy metals caused by the temporary
disposal of steel scrap on unprotected earthen surfaces. Steel scrap is used as a raw material
for steel production. As an example of this type of soil pollution, a survey of soil testing
carried out in the area of scrap yard at Sisak melt shop is given. In this area, steel scrap was
disposed of for many years and was exposed to the influence of atmospheric conditions
leading to soil contamination. Heavy metal concentrations in soil were investigat ed (Cd, Cr,
Cu, Hg, Ni, Pb and Zn). The results of the analysis of soil samples from the area of scrap yard
are compared with the results of the reference soil sample as well as with the recommended
heavy metals limit values in the soil intended for industrial and commercial purposes
according to the Croatian Soil Monitoring Program and with the heavy metals limit values in
the soil intended for agricultural purposes as well.
