تعيين غلظت عنصر سرب در بافت كبد ماهي زمين كن دم نواري Platycephalus indicus در مناطق ميناب، قشم و بندر خمير (خليج فارس) طي فصول زمستان و تابستان

Investigation and determination of lead concentration in liver of Platycephalus indicus in Minab, Qeshm Island and Khamir Port (Persian Gulf

اين پژوهش به منظور بررسي غلظت عنصر سرب در بافت كبد ماهي زمين كن Platycephalus indicus طي دو فصل زمستان و تابستان در مناطق ميناب، قشم و بندر خمير صورت گرفته است. غلظت عنصر سرب در كبد ماهي زمين كن در فصول متفاوت بين مناطق مختلف اختلاف معني دار نشان داد (0/05>P). غلظت عنصر سرب در اين ماهي بين جنس هاي نر و ماده در مناطق نمونه برداري اختلاف معني داري نشان نداد (0/05

This study was conducted to determine concentration of lead (Pb) in the liver of flathead (Platycephalus indicus) in Minab, Qeshm Island and Khamir Port in the Persian Gulf during winter and summer (n= 30). Concentration of lead was measured using Atomic Absorption Spectrometry (AAS). The results showed that, there were significant differences between stations for the concentration of lead in liver of P. indicus in winter and summer (P<0.05). There were not significant differences between concentration of lead in liver of males and females (P> 0.05). The results showed that, marine pollution (aquaculture, urban and industrial activities) in different area in the Persian Gulf and seasons are effective factors on bioaccumulation of lead in P. indicus.
