    Effects of endocrine disruptors occurring in aquatic environment

  • Popis výsledku v původním jazyce

    Chemicals, pesticides, pharmacologically active substances and many other types of contaminants have been constantly entering aquatic environment. Such a contamination results in negative effects on both human and aquatic biota. In few past decades, water pollution caused by endocrine disruptors has become a commonly discussed issue. Occurrence of endocrine disruptor residues in aquatic environment is ubiquitous and is mostly result of wastewater discharge and its imperfect purification in wastewater treatment plants. Because of its constantly increasing consumption, hormonal contraception seems to be a major problem concerning endocrine disruptors entering aquatic environment. Endocrine disruptors have been proven to have a potential to affect endocrine system of human and non-target aquatic biota. Thus, endocrine disruptors have the ability to negatively affect development, physiological function, sexual activity and reproduction of non-target fish and other water organisms. Sediment, water, and aquatic biota tissue analysis are examples of frequently used measurements in order to monitor concentrations of endocrine disruptor residues in the environment. Moreover, phospholipoprotein vitellogenin has been included to our study as a biochemical marker of exposure of endocrine disruptors to aquatic organisms. The effects of ethinylestradiol on Danio rerio triploid population have been observed in the present study through determination of vitellogenin concentration in body homogenate. All-male Danio reriopolulation was exposed to ethinylestradiol incorporated into feed at the highest tested experimental concentration of 0.1 mg/100g feed for the period of 10 weeks. The concentration of vitellogenin in this group was between 14545 and 48338 µg/ml. This research was supported by project PROFISH – CZ.02.1.01/0.0/0.0/16_019/0000869.
