    Effects of technology based effluent limits on receiving waters
    (Scibulcom Ltd, 2007) Gunes, Y.; Kaykioglu, G.; Gunes, E. H.; Karakaya, N.
    The control of point sources discharges and complex mixtures is an important component of protecting receiving water quality. In Turkey, to control complex discharges technology-based effluent limits are used. These limits are determined by considering only treatment technology and economy, while the quality of receiving water or carrying capacity of the ecosystem have not received much importance. In this study all of the effects and drawbacks of this method are discussed. The approaches used in the world and in Turkey are compared and the necessity of using discharge standards based on receiving water quality instead of present discharge standards is emphasised.

    Toxicity evaluation of industrial and land base sources in a river basin
    (Elsevier, 2008) Gunes, E. H.; Gunes, Y.; Talinli, I.
    In this study, an ecotoxicological survey of complex mixture effluents collected from textile, leather and municipal influents and effluents, an unsanitary landfill leachate, and river waters and sediments of the Ergene River Basin is presented. Acute toxicity tests were applied by bacterial luminescence method with Vibriofischeri and expressed as Toxicity Unit (T.U.) defined as 100/EC50. In parallel, conventional pollution parameters (COD, BOD, NH4, sulfide, color, etc.) and heavy metals were analyzed. The results indicate that river water and sediments are polluted severely and urgently need to control.
