In addition 78 samples were collected. T-Hg concentration  were  calculated  in relation to biometric factors. T-Hg was measured by the LECO AMA 254 Advanced Mercury Analyzer (USA) according to ASTM standard NoD-6722. Each sample was analyzed 3 times. Accuracy of T-Hg analysis was checked by running three samples of Standard Reference Materials; SRM 1633b, SRM 2711 and SRM 2709. Detection limit was  0.001mg/kg  in  dry weight. The minimum and maximum  concentration  ofT-Hg  in  dorsal  muscle  was  0.2ppm  in one year and 1.2ppm in five year class. The mean T-Hg significantly  increased  wit  age increased (P<0.05). The T-Hg mean concentration.  In 1 and 2 year classes was 0.17<x<0.5ppm, 1ppm="" 3="" 4="" and="" classes="" five="" in="" was="" year="">1ppm. Accamulation pattern ofHg was significantly as well as muscle>liver>spleen. T-Hg content in females was higher than males (P<0.05). Acceptable monthly intake without carcinogenic effects due to mercury  for women, men, juveniles and children was 270,  320,  125 and  59g per  month.  Consumption  of pike above 35cm. length should be avoided.</x<0.5ppm,></p> Pollution, Heavy metals, Pollutant, Mercury, Esox lucius 97 110 http://isfj.ir/browse.php?a_code=A-10-1417-62&slc_lang=fa&sid=1 G.R Ghasemzadeh غلامرضا قاسم زاده g_ghasemzadeh@yahoo.com 100319475328460016416 100319475328460016416 Yes A Esmaeli Sari عباس اسماعیلی ساری 100319475328460016417 100319475328460016417 No I Sharifpour عیسی شریف پور 100319475328460016418 100319475328460016418 No G Vosoughi غلامحسین وثوقی 100319475328460016419 100319475328460016419 No S.M Ghasempouri سیدمحمود قاسمپوری 100319475328460016420 100319475328460016420 No G Zolfaghari قاسم ذوالفقاری 100319475328460016421 100319475328460016421 No
