Abstract

In this study, pollution in Curuksu Stream of Menderes River has been followed by measuring the chemical and biological parameters on five predetermined stations for about 20 mon. Our previous studies have shown that Limnodrilus profundicola, Eristalis sp. and Chironomus thummi taxa are valuable bioindicators for the Curuksu stream and Limnodrilus profundicola Metallo-Thionein (MT) and EthoxyResorufi n-O-deEthylase (EROD) levels are valuable and useful biomarkers for biomonitoring heavy metals and PAHs pollutions, respectively. Cu-, Cr-, Cd- and Pb-type pollution was detected in all sediment samples taken from all of the stations, including reference station. Pollution source of these heavy metals are considered to be industrial wastewater, atmosphere and soil. Similarly, PAHs level was found to be considerably higher for Curuksu and Guzelkoy stations than other stations. These heavy metal- and PAHs-pollution were also confirmed with elevated MT and EROD levels measured with Limnodrilus profundicola sampl...
