“…P. australis and T. domingensis were the only species which showed the highest values of BCF for Hg and comparability of levels of this element with those present in the sediment, which suggests that these two macrophytes are not only useful as bioindicators of Hg but also for phytoremediation, as has been found in other studies (e.g. Lominchar et al, 2015). In the case of Cu, Mn and Zn, the present results indicate that all study species reflected the levels of these elements in the sediment.…”

The present study investigated the levels of As, Cd, Cr, Cu, Hg, Mn, Ni, Pb and Zn in the seagrasses Posidonia oceanica and Cymodocea nodosa, and in the wetland macrophytes Phragmites australis, Arundo donax, Typha domingensis, Apium nodiflorum, and Nasturtium officinale. Results showed that the bioaccumulation capacity from sediments, translocation, total levels in plant tissues, and bioindication of metals in sediments, are generally species-specific. In particular, the patterns of metals in the aquatic plants studied were overall independent of ecology (coasts vs wetlands), biomass, anatomy (rhizomatous vs non rhizomatous plants), and life form (hemicrytophytes vs hydrophytes). However, marine phanerogams and wetland macrophytes shared some characteristics such as high levels of heavy metals in their below-ground organs, similar capacity of element translocation in the rhizosphere, compartmentalization of metals in the different plant organs, and potential as bioindicators of Cu, Mn and Zn levels in the substratum. In particular, the present findings indicate that, despite ecological and morphological similarities, different plant species tend to respond differently to exposure to heavy metals. Furthermore, this seems to result from the species individual ability to accumulate and detoxify the various metals rather than being attributed to differences in their ecological and morpho-anatomical characteristics.

“…Bhatia and Goyal (2014) reported that macrophytes including Typha accumulated 2049-6648 μg metal per gram of dry plant biomass and (Mojiri et al 2013) reported that, under optimal conditions, T. domingensis removed 0.97, 0.47, and 0.37 mg kg −1 of Pb, Ni, and Cd, respectively. Various studies also reported high Hg bioaccumulation factors for Typha (Gomes et al 2014;Lominchar et al 2015;Bonanno and Cirelli 2017). In addition, phytoabsorption by Typha has been suggested for treating de-icing salts in road ditches (Morteau et al 2015).…”

“…Many studies and reviews have indicated that various species of Typha show promise for phytoremediation of metals in wastewaters due to their ability to bioaccumulate metals such Cd, Cr, Fe, Hg, Ni, Pb, and Zn (Demirezen and Aksoy 2004;Maddison et al 2009;Marchand et al 2010;Hegazy et al 2011;Mojiri et al 2013;Bhatia and Goyal 2014;Sultana et al 2014;Lominchar et al 2015;Bonanno and Cirelli 2017). In a review of metal removal in constructed wetlands, Marchand et al (2010) summarized removal rates for monocultures of Typha ranging from 48 to 99% for Cd, Cr, Fe, Ni, Pb, and Zn;moreover, Sultana et al (2014) found Cr removal efficiency rates for Typha ranging from 50 to 95%.…”

Typha (Cattail) Invasion in North American Wetlands: Biology, Regional Problems, Impacts, Ecosystem Services, and Management

et al. 2019

View full text Add to dashboard Cite

Typha is an iconic wetland plant found worldwide. Hybridization and anthropogenic disturbances have resulted in large increases in Typha abundance in wetland ecosystems throughout North America at a cost to native floral and faunal biodiversity. As demonstrated by three regional case studies, Typha is capable of rapidly colonizing habitats and forming monodominant vegetation stands due to traits such as robust size, rapid growth rate, and rhizomatic expansion. Increased nutrient inputs into wetlands and altered hydrologic regimes are among the principal anthropogenic drivers of Typha invasion. Typha is associated with a wide range of negative ecological impacts to wetland and agricultural systems, but also is linked with a variety of ecosystem services such as bioremediation and provisioning of biomass, as well as an assortment of traditional cultural uses. Numerous physical, chemical, and hydrologic control methods are used to manage invasive Typha, but results are inconsistent and multiple methods and repeated treatments often are required. While this review focuses on invasive Typha in North America, the literature cited comes from research on Typha and other invasive species from around the world. As such, many of the underlying concepts in this review are relevant to invasive species in other wetland ecosystems worldwide.

“…Typha domingensis modifies its leaf anatomy and photosynthesis in response to environmental conditions such as phosphorus eutrophication (Santos et al, 2015;Corrêa et al, 2016) and population density . This species is tolerant and can accumulate high levels of nickel, zinc (Mufarrege et al, 2014), mercury (Lominchar et al, 2015), and cromium (Mufarrege et al, 2015), however, its tolerance to Cd remains unclear. In addition, T. domingensis has been recently investigated due to its high potential to be applied in phytoremediation systems (Hegazy et al, 2011).…”

Cadmium tolerance of Typha domingensis Pers. (Typhaceae) as related to growth and leaf morphophysiology

et al. 2017

Typha domingensis (cattail) is a native macrophyte known by its capacity to tolerate several heavy metals effects and the potential use for phytoremediation. However, in despite that cadmium (Cd) is one of the most toxic pollutants; its effects in T. domingensis biology remain uninvestigated. Thus, the objective of this study was to study the tolerance of T. domingensis to cadmium contamination by evaluating its growth, Cd uptake, leaf anatomy and gas exchange. The experiment was designed using three cadmium concentrations (0, 10 and 50 µM) and ten replicates for 90 days. The cadmium uptake, growth, gas exchange, chlorophyll content and leaf anatomy were evaluated. Data was submitted to ANOVA and Scott-Knott test for P<0.05. Typha domingensis accumulates Cd proportionally to its concentration on the solution and the content of this metal was higher in roots as compared to shoots. Plants showed no significant modifications on growth parameters such as the biomass production, number of leaves, number of clones and the biomass allocation to organs. The photosynthesis, transpiration and chlorophyll content were not modified by Cd. Most anatomical traits evaluated were not modified by the metal but the stomatal density and the proportion of vascular tissues were reduced under 50 µM of Cd. In despite, the leaf anatomy showed no toxicity evidences for any Cd level. The absence of growth reduction and the stability of anatomical and physiological traits give insight about the Cd tolerance of this species. Therefore, T. domingensis is able to overcome Cd toxicity and shows potential for phytoremediation. Keywords
