This study was undertaken to determine the concentration of Pb in liver and muscle tissues of Platycephalus indicus fish collected from two creeks Jafari and Behad (Musa estuary, northwestern Persian Gulf) and was conducted to survey influence of total length and sex on accumulation of Pb in fish tissues during Agust 2010. Concentration of Pb in sediments was also measured. Total number of fish and sediment from each creek were respectively 30 and 9 samples. The samples were digested in laboratory according to MOOPAM 1999 instruction and lead concentration (in µg/g d.w.) was analyzed by Inductively Coupled Plasma-Optical Emission Spectrophotometer (ICP-OES). Results of regression showed a negative correlation between concentrations of Pb in liver and total length that reason of this negative correlation can be lesser absorption rate than excretion rate as the fish grows. In term of lead concentration in liver no significant difference was found between male and female (P>0.05) that indicates sex has no effect on accumulation of Pb in liver. Significant difference between studied areas in concentration of Pb in liver and sediment (P<0.05) was observed. In comparison with international standards FAO ,WHO and ISQG the mean value of Pb in muscle and sediment was lesser.
