Abstract
Background and Purpose: Birds, especially resident species, are valuable indicators of potentially toxic element (PTE) pollution in aquatic environments. These organisms are critical for assessing environmental health. This study aimed to evaluate the concentrations of potentially toxic elements (zinc, copper, cadmium, lead, selenium, and arsenic) in the feathers of the common moorhen (Gallinula chloropus) in the Zayanderud River.
Materials and Methods: Thirty feather samples were collected from common moorhens across various regions along the Zayanderud River. After collection, the feathers were prepared using an acid digestion method. The concentrations of the elements were determined using ICP-MS.
Results: The mean concentrations of zinc, copper, cadmium, lead, selenium, and arsenic were 59.07, 10.73, 0.49, 5.52, 2.33, and 2.66 μg/g, respectively. Based on established threshold levels, cadmium, lead, arsenic, and selenium concentrations were considered unfavorable. The proximity of the study area to industrial effluents and human sewage discharge points suggests that these pollutants in the common moorhen feathers likely originate from anthropogenic sources.
Conclusion: The findings of this research demonstrate that the common moorhen can be utilized as an indicator for assessing the concentrations of potentially toxic elements. These results emphasize the importance of assessing the environmental impacts of human activities on aquatic resources.
