Abstract

Odlagališta otpada predstavljaju globalni problem. Cilj istraživanja bio je provesti fizikalno-kemijska i biološka ispitivanja procjedne i podzemne vode uzorkovane uzvodno i nizvodno od odlagališta neopasnog otpada tijekom različitih godišnjih doba kako bi se utvrdio utjecaj odlagališta otpada na okoliš te procjenio rizik za ekosustav. Rezultati toksikoloških ispitivanja su u skladu s fizikalno-kemijskim analizama kojima je utvrđeno da tijekom ljetnih mjeseci, zbog intenzivnije degradacije i visokih temperatura, u procjednoj vodi su prisutne veće koncentracije različitih štetnih tvari. Podzemna voda uzorkovana uzvodno i nizvodno od odlagališta nije pokazala statistički značajan (geno)toksični učinak. Prema dobivenim rezultatima može se zaključiti da je navedeno odlagalište funkcionalno, trenutno ne predstavlja opasnost za ekosustav, a rezultati analiza mogli bi poslužiti kao referentne vrijednosti za ostala odlagališta u RH.

Abstract (english)

Landfills are a global problem. The present study dealed with physico-chemical and biological evaluation of leachate and groundwater sampled upstream and downstream of the non-hazardous landfills during different seasons in order to determine the impact of landfills on the environment and assess the risk to the ecosystem. The results of toxicological tests are in accordance with the physicochemical analyzes, which revealed that during the summer months, due to more intense degradation and high temperatures, higher concentrations of various harmful substances are present in the leachate. Groundwater sampled upstream and downstream of the landfill did not show a statistically significant (geno) toxic effect. According to the obtained results, it can be concluded that the landfill is functional, does not present any danger to the ecosystem, and the results of the analyzes could serve as benchmarks for other landfills in the Republic of Croatia.
