Abstract: (9223 Views)
Background and purpose: Today, environmental pollution, especially pollution of aquatic ecosystems, humans and other organisms are faced with serious problems. Endocrine disrupting chemicals are one group of chemical compounds that are important because of their significant adverse effects in humans and animals. Therefore, this study aimed to determine the concentration of 4-Nonylphenol, Bisphenol A and Octylphenol compounds in surface sediments of 4 areas in the coastal of Caspian Sea.
Materials and methods: Surface sediments samples taken from stations were studied and after preparation (Drying, Extraction, Clean up) the samples were injected into the Gas Chromatography-mass Spectrometry
Results: The concentration ranges of 4-Nonylphenol, Octylphenol and Bisphenol A compounds in surface sediment samples were as follows (in ng/gdw): 16.41-174.48, 5.63-41.90 and 0.3-30.66 respectively. The station that is located in the Anzali region showed significant amounts of all three compounds, Because the sources of these compounds there and the stations that are located in Kaporchal and Astara regions showed extremely low concentration. Compare concentrations were abtained from coasals of Caspian Sea with sediment quality standard showed that these compounds have potential to cause negative effects on the organisms in some stations
Conclusion: There are concerns about the presence of Estrogen Doubt Compounds in the aquatic ecosystems due to the adverse effects of them in biological communities health even at low concentrations.
