Abstract: (10 Views)
Background: Aquatic ecosystems are constantly exposed to a wide variety of hazardous chemicals or compounds with varying degrees of toxicity, which are released from various human sources. On the other hand, with the development of urbanization, industry and agriculture, which is a consequence of the increase in human population, various levels of pollution are created in surface waters, which affect human and animal life. Therefore, this study was conducted on the permanent Hableh River, which flows in the mountainous region north of Garmsar city, which is important and effective in terms of agriculture and ecology.
Materials and Methods: The aim of this study is to assess the abundance and diversity of benthic invertebrates and ultimately determine the biological integrity status of this river. In this study, manual sampling was conducted at five points between Firouzkouh and Garmsar counties. At each point, both biological indicators (benthic invertebrates) and concentrations of organic pollution and dissolved oxygen were evaluated.
Results: According to the results, various types of benthic invertebrates such as beetle larvae, fly larvae, dragonfly larvae, fly and beetle pupae, adult reef beetles, butterfly pupae and larvae, leeches, flatworms, roundworms, tapeworms, and snails were identified in this river.
Conclusion: From this case study, it can be concluded that these identified benthic invertebrate groups can be selected as representative indicators in the Hablehroud River in terms of the level of water resource pollution and habitat destruction.
