“…However, at higher concentrations, leaves turn yellowish-white, the margin of the lamina becomes dark brown, brownish discoloration, and shows degeneration of root. These results are in agreement with those reported for aquatic plants in general 30 .…”

The current work reports an ecofriendly approach to study morphological and biochemical responses of Pistia stratiotes L. (Water lettuce) were investigated. The assessment of morphological, biochemical parameters, and accumulation of chromium in free-floating macrophyte exposed at its various concentrations viz. 0.25, 0.50, 1.25, and 2.5 ppm of chromium at the regular intervals of 4, 8, and 12 days, respectively. Pistia showed morphological toxicity like withering of roots, chlorosis, and necrosis at higher concentrations (2.5 ppm) of chromium. However, the plant showed normal growth at a lower concentration of 0.25 and 0.50 ppm. The evaluation of biochemical parameters of test plants showed Total Chlorophyll, Carbohydrate, and Protein content was increased at lower concentrations (0.25 ppm) and decreased at higher concentrations (2.5 ppm) of chromium. The toxicity of chromium was found to be directly proportional to its concentration and duration of exposure. It is evident from the results that the accumulation of chromium can produce adverse effects on the morphology of test plant species at a higher concentration of chromium. This may be attributed to the stress-induced by chromium. INTRODUCTION:The rapid development of industrialization and urbanization, coupled with an alarming rate of population growth, has resulted in the large scale pollution of aquatic ecosystems by industrial and domestic wastewater discharge. Our environment, which consists of biotic and abiotic functions, is a part of the giant ecosystem called the biosphere or ecosphere. Biosphere complexly interfaces with other systems: hydrosphere, lithosphere, and atmosphere. Each of the systems is unique, with its own physicochemical factors and biotic components.

“…On the other hand, the positive load factor of temperature may be due to seasonal variations in weather or other industrial activities that can increase the surface water temperature. This will likely affect chemical reactions, reaction rates, aquatic life, and the suitability of the water for other uses [38].…”

In this study, spatiotemporal fluctuations in surface water quality in Vinh Long province, Vietnam, were conducted using entropy weighting, water quality index (WQI), and multivariate statistical techniques, such as cluster analysis (CA), principal component analysis (PCA), and discriminant analysis (DA). The samples collected at 63 monitoring locations in March, June, and September were measured for 15 parameters. Compared to the Vietnamese standard, surface water was contaminated with organic matters, nutrients, microorganisms, and salinity. DA identified the most typical parameters (pH, turbidity, TSS, EC, DO, Cl−, E. coli, coliform) in distinguishing temporal variations in water quality with greater than 75% of the correction. CA group 63 sampling sites into 22 clusters representing different land use patterns. WQI determined the worst water quality was found in the agricultural areas. Based on the results of entropy weighting, EC, coliform, N-NH4+, BOD, N-NO3−, and Fe had significantly controlled surface water quality. Four principal components obtained from PCA explained 66.45% of the variance, suggesting the influences of geohydrological factors and anthropogenic activities, such as domestic, market area, agriculture, and industry. The findings of this study can provide useful information for authorities to evaluate the effectiveness of monitoring systems and plan for water quality management strategies.

“…Water hyacinth (Eichhornia crassipes) is recommended to treat industrial wastewater, domestic wastewater, sewage effluents, and sludge ponds because it has (1) high absorption rate of different organic and inorganic contaminants (2) can tolerate an extremely polluted environment and (3) has a gigantic production rate of biomass [174]. Eichhornia crassipes has greater ability to remediate contaminants like arsenic, zinc, mercury, nickel, copper and lead from industrial and domestic wastewater streams [175][176][177].…”

Heavy-metal (HM) pollution is considered a leading source of environmental contamination. Heavy-metal pollution in ground water poses a serious threat to human health and the aquatic ecosystem. Conventional treatment technologies to remove the pollutants from wastewater are usually costly, time-consuming, environmentally destructive, and mostly inefficient. Phytoremediation is a cost-effective green emerging technology with long-lasting applicability. The selection of plant species is the most significant aspect for successful phytoremediation. Aquatic plants hold steep efficiency for the removal of organic and inorganic pollutants. Water hyacinth (Eichhornia crassipes), water lettuce (Pistia stratiotes) and Duck weed (Lemna minor) along with some other aquatic plants are prominent metal accumulator plants for the remediation of heavy-metal polluted water. The phytoremediation potential of the aquatic plant can be further enhanced by the application of innovative approaches in phytoremediation. A summarizing review regarding the use of aquatic plants in phytoremediation is gathered in order to present the broad applicability of phytoremediation.
