Measuring the concentration of lead in muscle and liver tissues of Pomadasys kaakan in Bushehr port, Iran

To evaluate the amount of lead (Pb) concentration in muscle and liver tissues of Pomadasys kaakan, sampling from desired fish was conducted in summer and autumn seasons of 2014 in the coastal area of Bushehr port, Iran. After biometrics, the liver and muscle tissues were separated and chemical digestion of samples were done and then, by using Plarograph tool, the concentration amount of lead was measured in the body. Based on the obtained results, the average concentration of lead in muscles tissues was about 6.01 ± 0.710 mg kg-1 dry weight and in liver tissue, it was about 6.12 ± 0.902 mg kg-1 dry weight. In this study, the amount of lead concentration did not have a significant difference between liver and muscle tissues (p > 0.05). Investigating the obtained concentration showed that based on WHO, FAO, ITS standards and Turkish guidelines, the amount of lead in the tissues of liver and muscles of the P. kaakan was higher than the limit of these standards in desired region.
