Abstract: (324 Views)
Introduction: This study aimed to measure the amount of estrogen and heavy metals (cadmium, mercury, lead, and arsenic) in the liver of industrial chickens from the selected areas of Ilam City, Iran.
Materials & Methods: This study is a cross-sectional study conducted on 30 liver tissue samples randomly selected from poultry farms in Ilam, Iran. The concentrations of the heavy metals (mg/kg) and 17-beta estradiol (ppb) were measured using atomic absorption spectrometer (AAS) and high-performance liquid chromatography (HPLC), respectively. The SPSS software version 21 was used for the data analysis.
Results: The mean level of 17-beta estradiol was 3.578 ± 0.756 ppb compared to the standard limit of 0.24 ppb (p < 0.05). The mean level of arsenic was 0.942 ± 0.842 mg/kg versus the standard limit of 0.1 mg/kg versus the standard limit of 0.24 ppb (p < 0.05). The mean concentrations of lead, mercury, and cadmium were 0.03±0.03, 0.11±0.13, and 0.015±0.02 mg/kg, respectively, and the differences were not significant compared to the standard values (all p values >0.05). The results showed no correlation between mean heavy metal levels and 17-beta estradiol. The target hazard quotient for arsenic was calculated to be 1.33.
Conclusion: The results show that the average levels of 17-beta estradiol and arsenic in the samples were higher than the standard limit. This may threaten the general health of residents in the area.
