A representative chromatogram of carp liver extract is shown in Fig. 2.
Despite the similar ˛- and ı-HCH concentrations measured in liver of carps from Is¸ ıklı and Sarayköy stations, these two OCPs were found to be significantly lower at Söke station (p < 0.05 vs. p < 0.01 , respectively). Concentrations of the other two HCH congeners, ˇand -HCH (lindane), did not differ between sampling sites. Similar to ˛- and ı-HCH, aldrin and endrin concentrations were found to be significantly lower at Söke station compared to the Sarayköy station
