“…Snow events and freezing temperatures occurred during the week of 5 November 2019 and road salt application took place throughout the city, contributing to the seasonal increase in Cl − concentrations. While some plants may incorporate Cl − [93], the lack of a significant decrease in Cl − during the growing season suggests that the plants are not removing the Cl − . However, the lower Cl − concentrations observed in the water exiting the AFW in the dormant season indicate some type of uptake is occurring, but the identifying the pathway is beyond the scope of this work.…”

Ever expanding urbanized landscapes are increasingly impacting streams that run through them. Among other stressors, urban streams often are host to elevated concentrations of nutrients, salts, and heavy metals. The pollutants, coupled with high temperatures, are drivers of ecosystem degradation in urban streams. The installation of artificial floating wetlands (AFWs) has been successful in mitigating the effects of urbanization in lakes and wastewater treatment ponds, but rarely have they been tested in streams. This pilot-study examined the ability of an AFW to improve water quality in an urban stream. The small, 90 m2 AFW was installed to improve the aquatic habitat and aesthetics of a small section of the Chicago River, Chicago, IL USA. Water samples and in-situ measurements were collected from the surface and at 0.3 m depth of upstream and downstream of the AFW. Samples were analyzed for nitrate-as-nitrogen, phosphate, chloride, and heavy metals. Comparison of upstream and downstream waters showed that the AFW lowered the concentrations of nitrate-as-nitrogen and phosphate during the growing season by 6.9% and 6.0%, respectively. Nitrate was also removed during the dormant season; however, phosphate was not removed during that time. Plant or microbial uptake of the nutrients are believed to be the dominant mechanisms in the growing season with denitrification serving as the primary pathway in the dormant season. Despite not having a measurable effect on the water temperature, the AFW was an effective means to reduce concentrations of nitrate and phosphorus, decreasing the potential for eutrophication.

In constructing a liquid enhancer, 300 mM NaCl was primed for 72 hours on sterile MTi2 seeds. Methods: After that, deionized water was used as a control, and SA alone (salicylic acid) (0.25, 0.5, 0.75, 1 mM) and only KCl (Potassium chloride) (10, 20, 30, 40, and 50 mM) were applied. As previously stated, germination parameters were computed. Then, the appropriate ratio of KCl to SA was combined, and its efficacy as a germination activator on the Salt-stressed MTi2 seeds was examined. The data analysis software used was SPSS Windows version 22. Results: To find the significant difference between treatments, data are first subjected to a twoway ANOVA with p≤0.05 confidence level. For purpose of comparing means, DMRT is next applied at a p≤0.05. According to the results, the best concentrations for boosting the germination and early growth of MTi2 seedlings in comparison to the control treatment were found to be 20-30 mM KCl and 0.5-0.75 mM SA. Furthermore, MTi2 seedling germination and early growth were more than 1x higher when the best concentrations of KCl (20-30 mM) and SA (0.5-0.75 mM) were combined. Conclusion: Salicylic acid (SA) and low levels of KCl applied to salt-stressed MTi2 seeds can help reduce the negative effects of salinity stress and enhance the percentage, rate, vigour, length, and biomass of the seedlings that germinate. As the conclusion, salt-stressed MTi2 seeds can benefit from an enhancer that increases germination at low concentrations of KCl and SA.
