Ciereszko W., 2001. Dynamics of the PCBs decline in selected organs of carp (Cyprinus carpio L.) during depuration in clean water. Acta Ichthyol. Piscat. 31 (2): 119-126.

The aim of this study was to determine the dynamics of PCB content decline in three selected organs and tissues (gill filaments, muscle tissue, perintestinal adipose tissue, liver, and alimentary tract) of cultured carp, previously exposed to Clophen A50 via oral route, in the course of their 40-day stay in PCB-free environment. The samples were analysed using gas chromatography. The highest decrease in PCB concentration, related to wet weight was noted for the perintestinal adipose tissue and the alimentary tract. The lowest PCB decrease in lipids was recorded in the liver (l0.0 %) and the highest one-in the alimentary tract. In decrease related to the total weight of the organs and tissue studied was the highest for the gill filaments (61.6 %) while the values compared for perintestinal adipose tissues showed a 6.6 % increase.
