Abstract: This paper deals with the residual pollutants in the meat and intestine of fish on the section of the Three George in the Yangtze River before the construction of the Three George Reservoir.The analysis of 75 samples of 22 species indicates greater content of heavy metals and volatile phenol in intestine than that in meat.The main residual pollutants charge ratio (MRPCR) of fish in meat are Cr6+ (25.8%),As (18.4%),volatile phenol (17.2%) and Pb (15.2%); Cr6+ (23.5%),As (19%),Pb (16.5%),volatile phenol (14.9%),Cd (11.1%) in intestine.According to residuals classification in the fish,the fish body in the reservoir section suffered light contamination,but has not exceeded the relevant food and sanitary standards;the main pollutant factors are Cr6+,As,Pb,volatile phenol and Cd.The building up of the dam will inevitably change the hydrology condition,cause the increase of some heavy metal and volatile phenol in fish body,which may exceed the food and sanitary standards and is detrimental to ecology and human health.

Key words: the Three George Reservoir, fish body, heavy metal, volatile phenol
