Antioxidant responses, lipid peroxidation and blood aminotransferase activity in Liza persicus in the northern Persians Gulf (case study: the Boushehr Province)

Xenobiotics change the physiological homeostasis including balance between enzymes and lipid peroxidation in fishes. The present study investigated changes of some physiological responses such as blood aminotransferase enzyme، glutathione-s-transferase (GST)، glutathione reductase (GR) and lipid peroxidation (LPO) in Liza persicus in northern Persian Gulf (Boushehr province) as biomarkers in biomonitoring programs. Six stations (Haleh، Nakhle Taghi، Kangan، Gofreh، Solhabad، Shogab) and a reference site (Bonod) were selected in the Boushehr province. The fish samples had an average length of 16. 21 ± 1. 51 cm [mean ± SD] and weight of 44. 53 ± 11. 79 g. PAHs concentration of coastal sediment were measured using GC-MS and the biomarker were measured using biochemical and spectrophotometric method. There was a significant difference between Nakhle Taghi station (The nearest station to petrochemical complex) and the control site (Bonod). There was no significance difference in blood alanine aminotransferase (ALT) between the stations. There was a significant difference in GST among Haleh، Nakhle Taghi، Solhabad، Shogab and the control site (Bonod). However، there was a significant difference in glutathione reductase activity between the Gofreh station and the Bonod station. This study indicated that xenobiotics biomarkers in the stations with a high level of pollution had significant difference with the control site (Bonod). In conclusion، Liza persicus and the studied biomarkers are potentially suitable for future biomonitoring programs.
