Evaluation of toxic potential of municipal waste waters from wastewater treatment plant by zebrafish embryo toxicity test

In recent years zebrafish (Danio rerio) embryo became frequently used model organism in ecotoxicology research. Due to their short embryonic development and transparent chorion zebrafish embryos have been shown to be a useful tool for the detection of toxic substances and obtained results correlate well with results obtained for mammals. For that reason, toxic potential of waste waters from wastewater treatment plant Virovitica that receives municipal, hospital and sugar plant wastewaters was evaluated on zebrafish embryos. By conducting fish embryo toxicity test (FET) we summarized embryotoxic/teratogenic effects and gained insight into the toxicity of pretreated and treated waste waters on aquatic organisms. Obtained results show that zebrafish embryo can be used as a valuable tool for potential toxic evaluation of waste waters.
