Abstract
Aim. To identify the features of accumulation of chemical elements by some types of macrophytes of the Volga Delta.
The objects of the study were common mulberry (Spirodela polyrhiza L.) and dark green hornwort (Ceratophyllum demersum L.). Plant sampling was carried out in the Volga Delta. The concentration of chemical elements was determined using atomic absorption spectrometry.
As a result of the studies conducted, some similarities in the accumulation of metals Spirodela polyrhiza and Ceratophyllum demersum are shown.
Thus, the plant species studied accumulate iron and manganese to a greater extent, whereas the cadmium content is minimal. At the same time, the species specificity of plants to accumulate chemical elements was noted: compared with Spirodela polyrhiza, Ceratophyllum demersum revealed a higher content due to the biological and physiological characteristics of the plants investigated.
Ceratophyllum demersum has the ability to concentrate chemical elements such as Fe, Ni, Pb and Zn from the environment more efficiently than Spirodela polyrhiza. In this regard, the dark green hornwort is recommended as an indicator species in monitoring pollution of aquatic ecosystems.
Supporting agencies: The research was carried out with the financial support of the Russian Science Foundation grant No. 23‐24‐10043.
