“…Although this is much higher than our measured 1.2 mg·g −1 , it should be noted that the minimum starting concentration of Na + in the initial solution used in that experiment was more than 4 times greater than the concentrations found in the typical greenhouse effluent. This general correlation between the enhanced salt accumulation (particularly the accumulated Na + and Cl − ) in the plant tissue and the higher starting salt concentrations up to a certain level, has been reported in other studies as well (e.g., [25][26][27][28]). Nonetheless, Ca 2+ , Mg 2+ and K + contents in the halophytes biomass are much less sensitive to salinity variations (e.g., [28,29]).…”

“…Elsewhere, in pilot scale wetlands planted with S. tabernaemontani, the plant's Na + tissue content was found highest at the longest nominal residence time (6.7 days) and lowest at the shortest residence time (1.9 days) [23]. Moreover, one week of retention time was recommended for salt phytoremediation using T. angustifolia mainly due to its higher Cl − absorption during that time [26]. Considering the longer HRT applied in the studies with effective ion accumulations, it can be concluded that the HRT of 3.7 days implemented in the present study was a critical factor resulting in the relatively small EC reduction.…”

Abstract:The dissolved salt ions that are not absorbed during irrigation of greenhouse crops are gradually accumulated in the nutrient solution resulting in levels of salinity high enough to damage the crops. This water salinity presents operational and environmental challenges as the nutrient-rich greenhouse effluent should be discharged to the environment when deemed unsuited for irrigation. In this pilot-scale study, the potential of passive salt reduction (phytodesalination) in gravel and wood-chip flow-through reactors was evaluated using seven plant species including Schoenoplectus tabernaemontani, Andropogon gerardii, Typha angustifolia, Elymus canadensis, Panicum virgatum, Spartina pectinata and Distichlis spicata along with an unplanted control reactor. While the unplanted system outperformed the planted units with gravel media, the wood-chip bioreactors with S. tabernaemontani and S. pectinata improved the greenhouse effluent reducing the solution conductivity (EC) by a maximum of 15% (average = 7%). S. tabernaemontani and D. spicata showed higher accumulated contents of Na + and Cl − in comparison with T. angustifolia and S. pectinata. Overall, S. tabernaemontani was selected as the most capable species in the wood-chip bioreactors for its better salt management via EC reduction and salt accumulation. It was however concluded that further treatment would be required for the greenhouse effluent to meet the stringent irrigation water quality guidelines in order not to pose any adverse effects on sensitive crops. Finally, the present hydraulic residence time (HRT = 3.7 days) and the solution salinity concentration were identified as the potential factors that may be limiting the efficiency of plant salt uptake, emphasizing the need for conducting more research on the optimization and enhancement of passive desalination systems for the greenhouse effluent.

“…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).…”

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

et al. 2019

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.

“…Cl − uptake by plants in the ponds’ vegetated buffers could also contribute to Cl − inputs being higher than outputs (Guesdon, de Santiago‐Martín, & Galvez‐Cloutier, 2016; Morteau, Triffault‐Bouchet, Galvez, & Martel, 2015; Rozema, Gordon, & Zheng, 2014). However, as plants draw in very small quantities of Cl − and consistent plant uptake of Cl − tends to rely on plant harvest, which did not occur in DH or OAK, the impact of plant uptake of Cl − on the overall mass balance is negligible.…”

Quantifying chloride retention and release in urban stormwater management ponds using a mass balance approach

Chloride (Cl −) in urban waterways largely originates from runoff containing deicing salts. Cl − is retained in watersheds after deicing ends, resulting in deleterious effects on aquatic biota. Stormwater management ponds (SWMPs), designed to mitigate 'flashy' urban runoff response, are known to impact pollutant transport. However, there is little information on what role SWMPs play in the timing and magnitude of Cl − transport over different timescales. This study quantifies the mass of Cl − retained in two SWMPs over varying timescales. Both ponds are in an urbanizing watershed in south-central Ontario; one drains a commercial area, the other, a residential area. High frequency measurements of water level and specific conductivity, from which flow and Cl − concentration were derived, were taken with sensors at pond inlets and outlets. For one SWMP, data were also collected upstream and downstream of the confluence of the pond outflow and the receiving creek to quantify the in-stream response to Cl −laden pond outflows. The findings suggest that SWMPs likely play a role in watershedscale Cl − retention; one SWMP consistently retained Cl − while the other had variable retention and release of Cl −. In the receiving creek, Cl − concentrations downstream of the pond exceeded the acute toxicity threshold for aquatic organisms twice as often as concentrations upstream of the pond, and Cl − pulses corresponded to Cl − release events from the pond. The results of this study suggest that SWMPs concentrate spatially distributed salt inputs and modify the timing and magnitude of their release to receiving streams. Stream reaches that receive water inputs from SWMPs may be more vulnerable to Cl − toxicity than reaches that do not receive flow via SWMPs. The results of this study will help parameterize the role of SWMPs in watershed-scale Cl − transport models and geospatial models of salt vulnerable areas.
