Sažetak
Toxicological safety of new procedure for the neutralisation/purification of wastewater originated from zinc plating facility was investigated. Wastewater was treated with alkaline solid residue-by-product of zinc recovery from electric arc furnace dust. For determination of citotoxic potential of untreated and purified wastewater MTT test on HEp2 (human laryngeal carcinoma) and HeLa (human cervical carcinoma) cells lines and alkaline comet assay on human leukocytes were used. 100% of the sample as well as different dilutions were tested. Compared to negative control 100, 75 and 50 % of the sample of untreated wastewater significantly decreased survival of both HEp2 and HeLa cell lines. In the presence of undiluted sample survival percentage of HeLa and HEp2 cells were only 2.3 and 0.3 % respectively. Only undiluted purified wastewater showed slight but insignificant decrease of the survival of both cell lines. Even 0.5 % of the sample of original electroplating wastewater exhibited significantly higher value of all comet assay parameters compared to negative control. There was no significant difference between negative control and purified wastewater for any of comet assay parameters. Significantly lower level of primary DNA damage recorded after treatment with purified water, even comparable with negative control, confirmed effectiveness of the purification process.
