“…In the UK, the combined cost of controlling invasive plants, together with their economic impact, is estimated to be £1.7 billion per annum(The Great Britain Non-native Species Secretariat, 2015). Therefore, there is a significantjuxtaposition between using species of invasive plants in phytoremediation, and management strategies to control invasive species (Rodríguez et al, 2012). Given that in many cases the complete eradication of invasive aquatic macrophytes such as Eichhornia crassipes is unlikely, it may be more appropriate to exploit these macrophytes as part of an integrated management strategy that controls the spread of these species whilst at the same timeeffectively removing nutrients and metals, capturing suspended sediment, and harvesting the biomass for economic gain (Patel, 2012;Yan et al, 2017).…”

“…However, there are important factors to consider including the containment of macrophytes to avoid transferto other water bodies (e.g. via contaminated harvesting equipment or through downstream spread of fragments), including the most appropriate harvesting technique, and the sustainability of exploiting such an ecological engineering systems (Rodríguez et al, 2012;Yan et al, 2017). The sitespecific context will likely determine the appropriateness of active harvest of invasive aquatic plants (Yan et al, 2017).…”

“…Water hyacinth possess a complex root system, with root length varying from 200 to 2000 mm and root surface area varying from 30 to 60 m 2 per individual macrophyte [ 16 ]. The roots of water hyacinth may play an important role in the removal of heavy metals and antibiotics.…”

Batch experiments were conducted to investigate the adsorption characteristics of tetracycline (TC), and the interactive effects of copper (Cu) on the adsorption of TC onto water hyacinth roots. TC removal efficiency by water hyacinth roots was ranging from 58.9% to 84.6%, for virgin TC, 1:1 TC-Cu and 1:2 TC-Cu. The Freundlich isotherm model and the pseudo-second-order kinetic model fitted the adsorption data well. Thermodynamics parameters ΔG0 for TC were more negative in the TC plus Cu than the TC-only treatments, indicating the spontaneity of TC adsorption increased with increasing of Cu concentrations. An elevated temperature was associated with increasing adsorption of TC by water hyacinth roots. The additions of Cu(II) significantly increased TC adsorption onto water hyacinth roots within the pH range 4 to 6, because copper formed a strong metal bridge between root surface and TC molecule, facilitating the adsorption of TC by roots. However, Cu(II) hindered TC adsorption onto water hyacinth roots on the whole at pH range from 6–10, since the stronger electrostatic repulsion and formation of CuOH+ and Cu(OH)2. Therefore, the interaction between Cu(II) and TC under different environmental conditions should be taken into account to understand the environmental behavior, fate, and ecotoxicity of TC.

“…Invasive free-floating plants, such as Eichhornia crassipes, are known to cause significant ecological damage by altering water quality [4,5], reducing the abundance and richness of wetland plant communities [6], and even affecting bacteria and algae [7]. Moreover, dense mats of free-floating invaders can reduce submerged macrophyte biomass and diversity [8,9], mostly because they generate dark conditions, secrete allelochemicals and compete fiercely with other species for nutrients and space [10,11].…”

Abstract:Invasion by free-floating species, such as Eichhornia crassipes, is one of the most critical threats to the biodiversity and sustainability of wetland ecosystems, where all plants experience spatial heterogeneity in substrate nutrients. However, few studies have focused on the effects of free-floating invaders on the capacity of submerged plants to utilize substrate nutrients. A 10-week greenhouse experiment was conducted to test the effects of free-floating invasive E. crassipes (presence or absence) on the growth of Ceratophyllum demersum and Myriophyllum spicatum, and their capacity to use heterogeneous and homogeneous substrate nutrients. We found that the invasion of E. crassipes could significantly decrease the growth of both submerged C. demersum and M. spicatum and that substrate nutrient heterogeneity increased the growth of C. demersum (approximately 30% in total biomass and 40% in the number of nodes) but not of M. spicatum. The two submerged species have different strategies to address invasion by E. crassipes. These results indicate that E. crassipes can prevent the growth of submerged plants even if the submerged plants can effectively use heterogeneous nutrients. For the effective conservation of submerged macrophytes in wetlands, measures should be taken to restrict the spread of invasive free-floating species.
