Abstract
We The convergence balls as well as the dynamical characteristics of two sixth order Jarratt-like methods (JLM1 and JLM2) are compared. First, the ball analysis theorems for these algorithms are proved by applying generalized Lipschitz conditions on derivative of the first order. As a result, significant information on the radii of convergence and the regions of uniqueness for the solution are found along with calculable error distances. Also, the scope of utilization of these algorithms is extended. Then, we compare the dynamical properties, using the attraction basin approach, of these iterative schemes. At the end, standard application problems are considered to demonstrate the efficacy of our theoretical findings on ball convergence. For these problems, the convergence balls are computed and compared. From these comparisons, it is confirmed that JLM1 has the bigger convergence balls than JLM2. Also, the attraction basins for JLM1 are larger in comparison to JLM2. Thus, for numerical applications, JLM1 is better than JLM2.

Abstract
Under the same conditions, we propose the extended comparison between two derivative free schemes of order six for addressing equations. The existing convergence technique used the standard Taylor series approach, which requires derivatives up to order seven. In contrast to previous researchers, our convergence theorems only demand the first derivative. In addition, formulas for determining the region of uniqueness for the solution, convergence radii, and error estimations are suggested. As a consequence, we broaden the utility of these productive schemes. Moreover, we present a comparison of attraction basins for these schemes to obtain roots of complex polynomial equations. The confirmation of our convergence findings on application problems brings this research to a close.

Current Traditional Medicine, 8(6). https://doi.org/10.2174/2215083808666220510115510
Abstract
This study is an effort to document extensively and systematically the ethnobotanical and ethnomedicinal knowledge in the four districts (Puri, Cuttack, Bhadrak, and Mayurbhanj) of Odisha in Eastern India. It provides new insights into the rich ethnomedicinal knowledge and plants biodiversity in these four districts. The method of convenience sampling was conducted to get the ethnobotanical and ethnomedicinal knowledge of the healers. Semi-structured interviews were conducted, and the information got was quantified and documented with the aid of various databases. Eleven traditional healers endowed information on their traditional medicinal knowledge. 74 plant species belonging to 44 botanical families are documented and among these 44 botanical families, five (Rutaceae, Malvaceae, Astaraceae, Annonaceae, and Euphorbiaceae) are mostly used by the healers. The healers mainly use leaves and roots in the medicine’s preparation. Twenty-five ailments are treated by these traditional healers, which are majorly dominated by dermatological treatments. The pharmacological mining of these 74 plants revealed that a few pharmacological and biological activities of each medicinal plant had been studied. Our study revealed that these four districts of Odisha have a rich biodiversity of medicinal plants. Promoting the plantation of some of these species can enhance the income of the traditional healers of these districts and simultaneously make the exploitation of these plant species sustainable. We also found that the pharmacological and biological activities of many plant species are yet to be explored.

Furfural removal from water by bioremediation process by indigenous Pseudomonas putida (OSBH3) and Pseudomonas aeruginosa (OSBH4) using novel suphala media: An optimization for field application. Groundwater for Sustainable Development, 20, 100895. https://doi.org/10.1016/j.gsd.2022.100895
Abstract
The release of furfural as effluent from industries has been considered a major pollution source since it adversely affects health and the environment. The main objective of this article is to employ the effective indigenous bacteria to remove the furfural from wastewater. In the present study, the indigenous isolates OSBH3 (strain number) and OSBH4 (strain number) were isolated from furfural-containing-oily-sludge and were identified by 16S-rRNA technique with >99% nucleotide similarity as Pseudomonas putida (P. putida) (Acc. No. GU329915) and Pseudomonas aeruginosa (P. aeruginosa) (Acc. No. GU329916) respectively. Thus, the indigenous P. putida (OSBH3; Acc. No. GU329915) (in presence of modified nitrogen-phosphorous-fertilizer media), can be applicable for furfural (Toxic) remediation from industrial effluent water by the eco-friendly process.

Abstract
A mononuclear Mn(III) complex, [MnIIIL(Cl)], has been synthesized using a newly designed compartmental ligand, H2L. Both of them have been characterized by single crystal X-ray crystallography. Interestingly the complex behaved as a model of catechol oxidase toward oxidation of 3,5-Di-tert-butyl catechol to the corresponding quinone. The progress of the oxidation process has been monitored with the help of 1H-NMR spectroscopy after stirring the reaction mixture in methanol at room temperature. NMR spectral data confirmed completion of the process after 48 hours. Kinetic investigations were carried out in methanol-water mixture and acetonitrile to check the effect of solvent on the rate of reaction, if any. A greater turnover number was obtained in acetonitrile than methanol-water medium.

Abstract
Arsenic (As) is one of the most prolific natural contaminants in water resources, and hence, it has been recognized as an emerging global problem. Contamination of As in rice and baby cereal via export/import is a global problem. Ensuring As-safe drinking water and food is still not considered as a human right. It is a key priority in UN’s 2030 Sustainable Development Goals (SDGs) and UNESCO’s global priorities. A global umbrella for sharing knowledge, experience and resources is an urgent need. This analysis and review lend a fresh perspective for a sustainable As mitigation by 2030.

Abstract
An algal biochar-based nanocomposite (nAgBC) was synthesized and employed as a low-cost adsorbent for Congo red (CR) removal. nAgBC efficiently adsorbs the Congo Red. Maximum adsorption efficiency of 95.92% (18 mg/L CR) was achieved (qe = 34.53 mg/g) with 0.5 g/L of nanocomposite after 60 min, at room temperature (300 K) at pH 6. The surface functional groups (–OH, NH, Cdouble bondO, SO, and CH) of nAgBC are significant to remove pollutant. The process corresponds to multilayer chemisorption onto the heterogeneous surface takes place for removal. The mechanisms involve by an electrostatic interaction with H-bonding and CR supramolecule.

Marine Pollution Bulletin, 181, 113905. https://doi.org/10.1016/j.marpolbul.2022.113905
Abstract
Heavy metals (HM) are the major proximate drivers of pollution in the mangrove ecosystem. The HM concentration was observed higher at active-tidal-sediment compared to partially-active-sediment. Geo-accumulation index (Igeo) and contamination factor (CF) indicated the tidal-sediment was highly contaminated with arsenic (As) and moderately contaminated with Lead (Pb) and Zinc (Zn). The isolated IRB (Priestia megaterium, Bacillus safenis, Bacillus aerius, Bacillus subtilis, Bacillus velenzenesis, Bacillus lichenoformis, Kocuria palustris, Enterobacter hormaechei, Pseudomonus fulva, and Paenibacillus favisporus; accession number OM979069-OM979078) exhibited the arsenic resistant behaviour with plant-growth-promoting characters (IAA, NH3, and P-solubilization), which can be used in mangrove reforestation and bioremediation of HM.

Abstract
Arsenic sources are both natural and anthropogenic in Africa. The factors of climate change can trigger As release in Africa, and distributed in water, soil, sediment, fish, and vegetation. >50% of water exceed WHO value of 10 μg/L. Tanzania and Ethiopia have reported high levels of As in human tissues, toenails, and urine among pregnant women related to groundwater. In urine, concentrations up to 150 μg/L were reported among pregnant women depending on As contaminated drinking water within Geita gold mining areas in the north-western part of Tanzania. Significant studies on human exposure to As and health effects are required in Africa.

Geogenic contaminants and groundwater quality around Lake Victoria goldfields in northwestern Tanzania. Chemosphere, 307, 135732. https://doi.org/10.1016/j.chemosphere.2022.135732
Abstract
The water of Lake Victoria goldfields in Geita and Mara districts were analysed (pH, EC, Eh), major ions, and trace elements. The concentration levels of the major ions were mostly within the World Health Organization (WHO) drinking water standards in the following order of their relative abundance; for cations, Ca2+∼Na+>Mg2+>K+ and for anio ns was HCO3− > SO42− > NO3−, Cl− > PO43−.48% of water samples exceeded the WHO guideline value of 10 μg/L arsenic for drinking purposes. Consumption of arsenic-polluted water poses health risks to the exposed communities in the study area. Regular update of water quality monitoring programs is recommended.

Environmental DNA analysis as an emerging non-destructive method for plant biodiversity monitoring: a review. Aob Plants, 14(4). https://doi.org/10.1093/aobpla/plac031
Abstract
Environmental DNA (eDNA) analysis has recently transformed and modernized biodiversity monitoring. The study evaluates the development of eDNA-based methods for (vascular) plants, comparing its performance and power of detection with that of traditional methods, to critically evaluate and advise best practices needed for innovating biomonitoring. eDNA also has considerable potential for plants, where successful detection of invasive, endangered and rare species, and community-level interpretations have provided proof-of-concept. Additionally, eDNA methods were found to be effective in studying species interactions, community dynamics, and even effects of anthropogenic pressure. It can be adopted and implemented, rapid, cost-effective, and non-invasive plant monitoring approach.

Environmental Research, 214, 114043. https://doi.org/10.1016/j.envres.2022.114043
Abstract
Fluoride (F) is one of essential elements, however, in higher dose it causes fluorosis, dental, skeletal growth problems, etc., worldwide. Efficient and cost-effective F-removal from water is essential. Biochar-based-materials can remove fluoride by adsorption process under low pH, biochar dose, initial concentration, temperature, and co-existing ions. Modified biochar possesses various functional groups (–OH, –C=C, –C–O, –CONH, –C–OH, X–OH), in which enhanced –OH) onto the surface, plays a significant role in fluoride adsorption via electrostatic attraction and ion exchange. Regeneration and reusability of biochar sorbents need to perform to improve removal efficiency and reusability in field conditions.

Hydrobiologia, 849(19), 4241–4257. https://doi.org/10.1007/s10750-022-04979-6
Abstract
Cryptic invasions are difficult to distinguish and easily overlooked by conventional identification methods, creating false biodiversity information. Molecular markers represent the only reliable method to distinguish cryptic species. Environmental DNA (eDNA) method was assessed in semi-natural (mesocosm) and natural waterbodies across Taiwan for species identification. P. canaliculata and P. maculata shells demonstrated overlapping qualitative and quantitative measures, which were unable to differentiate species. However, DNA-based barcoding (COI gene) differentiated P. canaliculata, and P. maculata and revealed their distribution. eDNA study quickly and effectively detected P. canaliculata and P. maculata, which could revolutionize tracking two immensely invasive and economically destructive species.

Abstract
Plant–animal interactions (PAI) represent major channels of energy transfer through ecosystems, where both positive and antagonistic interactions simultaneously contribute to ecosystem functioning. Environmental DNA (eDNA)-based monitoring represents an increasingly common, nondestructive approach for biodiversity monitoring, which could help to elucidate PAI. eDNA can be identified PAI such as pollination, herbivory, mutualistic, and parasitic relationships, they have often identified higher taxonomic diversity in several direct comparisons with DNA-based gut/bulk sampling and conventional survey methods. However, the research needs to include the influencing factors of eDNA detection involved in PAI, methodological standardization, and more inclusive sequence reference databases.

Abstract
The textile industry is one of the largest and high water-consuming manufacturing sectors in the world and hence releases a huge volume of wastewater. At different stages of textile production, large amounts of effluents are discharged which are heavily contaminated with dyes and fluorescent brighteners, vegetable oils, fats, dissolved solids, organic acids, suspended solids, toxic metals, fibres, polymeric impurities, etc. This pollution severely deteriorates the aquatic ecosystems and imposes an unseen threat to humans, marine life, and the environment. Removal of such pollutants from wastewater is urgently demanding effective methods of treatment. In this context, several techniques such as membrane separation, ion exchange, coagulation, ozonation, adsorption, chemical reaction, electrodialysis, filtration, photocatalytic degradation, flocculation, reverse osmosis, biological degradation, etc have been adopted worldwide. Among the above-mentioned technologies, adsorption is proved to be one of the efficient methods for the removal of contaminants from wastewater owing to its simple design, ease of operation, high adsorption capacity, insensitivity, flexibility, etc. Recently, carbon nanotube (CNT) particularly surface-modified CNT and its derivatives as adsorbents are paid a lot of attention among the scientific community and industries across the globe due to their distinctive features i.e. cylindrical hollow structure, large surface area, flexible surface chemistry, higher sorption capacity, and well-flourished mesopores. Hence, in this chapter, we focus on the role of surface-modified carbon nanotubes in the removal of textile effluents.

Abstract
The last few decades have evidenced the growth and maturation of electroanalytical techniques with voltammetry at the center of the field. The early stages of this method encountered many problems making it less significant as compared to spectroscopy, chromatography, and electrophoresis. However, advancement in the late 20th century was mostly driven by sophisticated and inexpensive instrumentation including operational amplifiers, Polaroid land cameras, etc. The voltammetry techniques exhibit merits of superior sensitivity with a wide range of inorganic and organic species (10−12–10−1 M), a large temperature span, simultaneous measurement of several analytes, easy and rapid analysis, capability to govern mechanistic and kinetic parameters, generation of different types of waveforms with simplicity, and capability to measure small currents. Researchers can usually explore these advantages to quantify the electrochemical properties of a diverse range of compounds. It has been proved to be useful to conduct fundamental studies on redox reactions in different media, electron transfer processes, adsorption mechanisms, transport properties, and thermodynamics of solvated species. Applications also extend to study compounds of pharmaceutical interest and can prove to be effective in the analysis of complex structures when combined with HPLC. This chapter will cover the development of the major types of voltammetric techniques and their applications to different fields of study.

Abstract
Remarkable expansions have been made in inorganic synthesis applying, or in the existence of ILs (ionic liquids), which has led to the development of sundry compounds with fascinating characteristics. ILs interact with the growing system through H-bond “co-π-π stacking” mechanism, forming a variety of morphologically different hybrid materials under mild reaction conditions. This creates an ordered solvation layer of ILs on the surface, which influences the interfacial interactions. Thus, differences in size, geometry, polarity, and coulomb coupling forces between cations and anions, which influence ILs’ viscosity and transition temperatures, directly contribute to the final produced particle’s morphology, size, and compactness.

Abstract
Arsenic, a toxic element, needs to remove from water. Nanofiltration applications at large scales are obstructed by the difficulty of As(III) (most toxic form) removal and fouling issues. Application of nanofiber membranes in arsenic remediation is also described: these membranes, characterized by high surface area, uniform pore-size distribution, and improved pore connectivity, exhibit excellent adsorption capacity. Although the research activities in this field have made progress, several problems need to be solved, such as improvement of the porosity and the size of the pores, and the mechanical strength for promoting their use in industrial operating conditions.

Abstract
Novel approach of data analysis by considering the spatial aspects of fluoride (WHO limit 1.5 mg/L) in the aquifers of Tanzania (>80% households depend on groundwater), was studied. Combination of spatial statistical methods and Geographical Information Systems (GIS) tools to identify and map potential and significant risk-zones of geogenic fluoride contamination. High-risk-zones in terms of dental caries exist around major stratovolcanoes, especially Mt. Kilimanjaro and along the EARV escarpments at high elevations. The high-risk-zones in terms of fluorosis exist in the lowlands at the foot of major stratovolcanoes, especially Mt. Meru and Mt. Hanang’ in Arusha and Manyara regions, respectively.
