“…Various antioxidant activities such as scavenging activity of DPPH, hydrogen peroxide (H 2 O 2 ) and ABTS as well as ferric reducing antioxidant power (FRAP) assay were carried out as described earlier [14]. For different radical scavenging activities, 20-100 µg ml −1 concentration of NPs was used.…”

Selenium and silver nanoparticles (NPs) were synthesized using Spermacoce hispida aqueous leaf extract (Sh-ALE). The optimum condition required for the synthesis of Sh-SeNPs was found to be 30 mM selenious acid solution to Sh-ALE at the ratio of 4:46, pH 9, incubated at 40 °C for 10 min. On the other hand, for Sh-AgNPs the optimum condition was found to be 1 mM AgNO3 to the Sh-ALE solution at the ratio of 4:46, pH 8, incubated at 40 °C for 10 min. SEM analysis revealed that both the Sh-AgNPs and Sh-SeNPs are predominantly rod-shaped. Sh-SeNPs and Sh-AgNPs were found to possess concentration-dependent antioxidant activity. However, Sh-SeNPs showed potent anti-inflammatory property, antibacterial property and anticancer activity against human cervical cancer cell in comparison to Sh-AgNPs. Phytochemical analysis, FTIR and GC-MS analysis showed that various flavonoids, saponins and phenolic compounds present in Sh-ALE catalysed the formation of NPs. Also, GC-MS analysis revealed that Sh-SeNPs are capped by synaptogenin B and derivatives of apigenin, quinoline and quinazoline. The advantage of attachment of such phytoconstituents on Sh-SeNPs for its potent biological activity in comparison to Sh-AgNPs is evident in in vitro conditions.

“…The identified heavy metals (Pb, Cr, and Cd) hold high potential to harm human health and the environment ( Johnson et al, 2018 ; Meena et al, 2018 ; Poonkuzhali et al, 2014 ). Toxicological effects of Pb on humans are well recognized as carcinogenic ( Elias et al, 2021 ; Hamsawahini et al, 2015 ).…”

“…Cd poisoning is one of the world's health issues that affects many organs and, in certain cases, causes death ( Fang et al, 2014 ; Oskarsson et al, 2004 ). Bronchial asthma, lung cancer, and nasal ulceration, as well as reproductive and developmental disorders are the major health risks associated with Cr poisoning ( Sullivan et al, 2021 ; Johnson et al, 2018 ; Poonkuzhali et al, 2014 ). These heavy metals may be conveyed from the face masks to the respiratory system via inhalation, skin contact, or saliva droplets.…”

“…Chromium (Cr) is 21st most abundant element of the Earth's crust. Among 129 leading pollutants, it is listed as one of the most harmful heavy metals by the United States Environmental Protection Agency (USEPA) as reported by Johnson et al (2018). USEPA limit for Cr in potable and discharged water is 0.05 and 0.1 mg L -1 , respectively (de Oliveira et al 2015).…”

The use of effluent from various industries by agriculture sector in developing countries may help to mitigate water scarcity and cost of fertilizers but pose considerable threats to entire ecosystem when heavy metals enter the food chain. The aim of the present study was to compare the growth and development of two biofuel tree species Jatropha curcas L. and Pongamia pinnata L. when exposed to 20 and 40 mL L −1 of effluent discharged from a local tannery along with tap water as a control. The physico-chemical attributes assessed for quality of effluent showed higher values and significantly higher chromium (Cr) concentration than other metals. Application of effluent induced profound formation of malondialdehyde (MDA) in P. pinnata. With regard to growth and pigments of plant species, a significant reduction (p≤0.05) in root length, dry shoot biomass, leaf area, chlorophylls and carotenoids occurred in P. pinnata but shoot length, collar diameter and root dry biomass remained unaffected. Similarly, J. curcas sustained root and shoot growth, dry biomass production, collar diameter and leaf area. Increased pigment contents were found at both effluent levels. The roots of P. pinnata accumulated 6 and 11 times more Cr at 20 and 40 mL L −1 , respectively, than control. While in J. curcas Cr accumulation was up to 9 folds in shoots at 40 mL L −1. Thus, the two species exhibited differential potential for Cr accumulation in their above and below ground tissues. The study signified the use of contaminated water for irrigation and potential of the species to act as phytoremediator to alleviate both water scarcity and metal contamination.
