“…The high ability of H. morsus-ranae to accumulate such metals as Mn, Fe, Co, Ni, Zn, and Cu has already been noted (Brekhovskikh et al, 2009;Polechońska, Samecka-Cymerman, 2016). Polechońska and Dambiec (2014) reported that the contents of Mn, Fe, and Cu in the leaves of H. morsus-ranae exceeded the average levels observed for other floating macrophytes, even in cases of low metal content in water bodies.…”

Aquatic ecosystems are very sensitive to industrial impacts, and, therefore, it is increasingly important to study the mechanisms underlying the tolerance of aquatic organisms to water pollution. Heavy metals (HMs) are among the most common and toxic pollutants of aquatic ecosystems. They have a particularly strong effect on macrophytes, which are in close contact with the aquatic environment and can accumulate metals in considerable quantities. Hydrocharis morsus-ranae L. is a floating macrophyte (pleistophyte) with a high capacity for accumulation of HMs. The aim of the present study was to assess the effect of industrial pollution on the redox reactions in H. morsus-ranae and to identify the role of low molecular weight antioxidants in adaptation of this macrophyte to unfavorable conditions. A comparative analysis of the physiological and biochemical characteristics of H. morsus-ranae from two (reference and impacted) water bodies was carried out. The study revealed an increased level of lipid peroxidation products in the leaves of H. morsus-ranae under industrial impact, which indicates oxidative stress. Nevertheless, this floating plant demonstrated fairly high resistance to adverse conditions, due to the synthesis of non-enzymatic antioxidants such as proline and soluble protein thiols. Revealing the response of macrophytes to pollution of water bodies will help predict the state of aquatic ecosystems with an increase in anthropogenic pressure

“…The studies conducted so far in natural aquatic ecosystems [GAŁCZYŃSKA, BEDNARZ 2012;POLECHOŃSKA, DAMBIEC 2014;POLE-CHOŃSKA et al 2017;POLECHOŃSKA, SAMECKA-CYMERMAN 2015;SKWIERAWSKI, SKWIERAWSKA 2013] show the possibility of occurrence of H. morsus-ranae in waters contaminated with metals, including heavy metals. The results confirming the accumulation of substantial amounts of metals in the plant's tissues as well as high efficiency of such accumulation in defined environmental conditions, support including H. morsus-ranae to a group of bioindicators of waters contaminated with metals [GAŁCZYŃSKA 2012;POLECHOŃSKA, DAMBIEC 2014;POLECHOŃSKA et al 2017;POLECHOŃSKA, SAMECKA-CYMERMAN 2015]. Chlorophyll content is one of the parameters which may indicate the viability of a bioindicator when conducting studies.…”

Anthropogenic pollution leads to increased concentrations of metals in the freshwater and macrophyte. Aquatic plants substantially contribute to the structure, function as well as and service provision of aquatic ecosystems. Our microcosm experiments were to test the possibility of the physiological response of Hydrocharis morsus-ranae to metal (Cd, Pb, Cu, Zn, Mn, Fe at three level of concentration) contaminated waters. Biomass was analysed at the beginning and at the end of the experiment. At the same time contents of photosynthetic pigments in leaves were estimated spectrophotometrically. We found that this macrophyte had the ability to grow in contaminated waters, but the effects of high concentration of isolated metals in water will indicate changes consisting in the disappearance of a significant part of biological populations were which manifested in alteration of the content of photosynthetic pigments as well as this plant's growth. We show that generally stress of Zn and Cu influenced the drop of dry biomass which was connected with a positive correlation between the amount of dry biomass and the content of chlorophyll a and carotenoids, or only carotenoids, respectively. The highest stress of Pb and Fe (third concentrations of these metals) also influenced the drop of biomass. We concluded that none of Cd concentrations were toxic to this plant, but the effect of Mn stress was not unequivocal. Moreover, plant growth was stimulated by low Fe concentrations (first concentration) demonstrating the hormesis effect. When plants were exposed to this metal, there was no evidence of damage to the photosynthetic processes.
