Polychlorinated organic compounds (PCOCs) were analyzed in Yangtse River se
diments. The results show that the concentrations of PCOCs in Yangtse River
sediments followed the order of DDTs > HCB > HCHs > PCBs, High PCOCs conce
ntrations were detected in sediments from station Y02a and Y02b, which are
located in the main input of the Yangtse River (Nanjing section). Results a
lso show that the PCOCs values were highly correlated with organic carbon c
ontent and heavy metal contamination. (C) 2000 Elsevier Science Ltd. All ri
