Abstract	U ovom radu je procijenjena kvaliteta otpadne vode jezera „Robule“ nastalog akumulacijom voda iz površinskog kopa rudnika bakra prije i nakon pročišćavanja kombiniranim elektrokemijskim postupcima. Toksični i genotoksični učinci procjedne vode istraženi su na dva testna organizma, voden buhi (Daphnia magna Straus.) i vodenoj leći (Lemna minor L.), putem Daphnia-, Lemna- i komet- testa. Parametri praćeni u Daphnia-testu su bili postotak inhibicije pokretljivosti vodenbuha nakon 24 i 48h izlaganja dok su pokazatelji toksičnosti praćeni u vodenoj leći bili sadržaj fotosintetskih pigmenata, malondialdehida (ukazuje na peroksidaciju membranskih lipida), neproteinskih tiola i ukupnih proteina te aktivnosti peroksidaza i katalaze nakon 24 sata i tjedan dana izlaganja. Otpadne vode su izazvale oštećenje molekule DNA, inhibiciju rasta, smanjenje omjera broja listića i broja kolonija, sadržaja pigmenata, neproteinskih tiola i ukupnih proteina te povećanje sadržaja malondialdehida i aktivnosti peroksidaza i katalaze. EC50 dafnija izloženih otpadnoj vodi otpadnoj vodi iznosila je 0,21% odnosno 0,06% nakon 24 odnosno 48h izlaganja. Vrijednosti gotovo svih parametara mjerenih u vodenoj leći izloženoj pročišćenoj vodi bile su slične vrijednostima kontrolnih biljaka, dok je mortalitet vodenbuha u nerazrijeđenoj pročišćenoj vodi bio vrlo nizak.
Abstract (english)	In the present study the quality of wastewater from the „Robule“ Lake, originated by the accumulation of wastewaters leaching from surface copper mine, prior to and following electrochemical purification was evaluated. Toxic and genotoxic effects of wastewater were evaluated with two test organisms, Lemna minor L. and Daphnia magna Straus., using Lemna, Daphnia and comet test. The percentage of mortality was evaluated as an indicator of toxicity in Daphnia test following 24 and 48h-exposure period. Photosynthetic pigments, malondialdehyde (indicates damage to membrane lipids), nonprotein thiols, total proteins and antioxidant enzymes peroxidase and catalase were evaluated as indicators of toxicity in duckweed following 24h- and 7-day exposure period. When exposed to wastewater, growth rate, N frond/N colony ratio, photosynthetic pigments, nonprotein thiols and total protein decreased while antioxidant enzymes, malondialdehyde content and DNA damage increased. EC50 for Daphnia magna was 0,21% and 0,06% following 24 and 48h-period of exposure, respectively. The values of almost all parameters observed in duckweed expose to treated wastewater were similar to control, while the mortality of daphnids in undiluted was very low.
