Abstract: (322 Views)
This study aimed to investigate the accumulation of the heavy metals lead (Pb) and nickel (Ni) in eggshells, egg contents, and nesting-site sediments of the hawksbill sea turtle (Eretmochelys imbricata) on Kish and Hendurabi Islands. To this end, 17 sampling stations were selected during 2017 and 2018, and samples were collected in triplicate at each station. After drying and acid digestion of the samples using nitric acid, metal concentrations were determined by flame atomic absorption spectrometry (FAAS). Statistical analyses were performed using SPSS version 21 and Microsoft Excel. Two-way analysis of variance (ANOVA) followed by Duncan’s multiple range test was applied at a significance level of 5%. The results indicated that while lead concentrations in sediments were within the range reported in similar studies, lead concentrations in eggshells and egg contents at some stations were higher than those reported in previous studies. These findings indicate the presence of environmental pressures caused by heavy metal contamination in the nesting habitats of this species on the studied islands.
