Ceratophyllum demersum

In natural conditions, Ceratophyllum demersum and Potamogeton pectinatus L. have been found to be effective adsorbents of Cd(II), Cu(II), and Pb(II). The adsorption percentage of the metals onto plant surfaces followed the pattern Pb(II) > Cu(II) > Cd(II). P. pectinatus biomass adsorbed a higher content of heavy metals than C. demersum. According to the results, both species are of interest in the phytoremediation and biomonitoring studies of polluted waters.122...

The masses of vegetation produced by weed species such as elodea (Elodea canadensis Michx.), coontail (Ceratophyllum demersum L.), and Eurasian watermilfoil Myriophyllum spicatum L.) remove herbicide residues from water (14). Najas sp. and Potamogeton sp. in plastic pools... 

Aquatic species were also found to be hyperaccumulators in wetland ecosystems (Williams, 2002). Ceratophyllum demersum is described as an arsenic accumulator (Kalbitz and Wenrich, 1998), whereas water hyacinths, Eichhornia crassipes, have been found to be effective in accumulating cadmium, lead, and mercury, and in the uptake of pesticides residues. Duckweed Lemna minor) and water velvet (Azolla pinnata) were both found to effectively remove iron and copper at low concentrations in laboratory experiments, and also cadmium. The yellow water lily (Nuphar variegatum) accumulated copper and zinc. 

APPLICATION OF PHYSICO-CHEMICAL METHODS IN MONITORING OF THE ANTHROPOGENIC POLLUTION BY AN EXAMPLE OF Ceratophyllum demersum L. 

The aim of the present chapter is to study the effect of pollutants on the chemical composition and anatomic structure of hydrophytic plant Ceratophyllum demersum L. (Homwort deep green) deep green by means of FTIR spectroscopy, SEM, and EDX. 

Ceratophyllum demersum L. occurs in Tver region in stagnant reservoirs with slowly flowing water, ponds, peaceful river backwater, cutoff meanders, and is able to grow both in clear and contaminated inhabitants [1,10]. Collection of the plants and water intake for chemical analysis were performed in water bodies of the city of Tver and Tver region classified by the factor of proximity to the sources of contamination in two groups—control and polluted (Table 1).

An indirect inhibition of photosynthesis was suggested by Aravind and Prasad [67], who observed a substitution of Zn " by Cd " in the active center of carbonic anhydrase of the submerged water plant Ceratophyllum demersum. While this...
