Subject: Enhancing Green Reduction of Graphene Oxide by Nyctanthes arbor-tritis Leaves towards Degradation of Organic Pollutants and Tunable Fluorescence
Keywords: Graphene oxide, Reduced graphene oxide, Nyctanthes arbor-tristis, Hydrothermal, Sol gel, Photoluminescence, Photocatalyst
Abstract: The present study explored two energy efficient simple methods for the effective application of the anti-oxidant property of the leaf extract of Nyctanthes arbor-tristis, a highly potent reduction of graphene oxide. The samples obtained from the green method were characterized in terms of structure, surface morphology and elemental composition. The data from the analytical tools of FTIR, FT-Raman, powder X-ray diffraction (PXRD), field emission scanning electron microscopy and energy dispersive x-ray spectroscopy (FE-SEM with EDAX) and ultraviolet diffuse reflectance spectroscopy (UV-DRS) studied the structure and property relationship and indicated the enhanced smooth layer structure of the synthesized samples. There was a drastic change in the surface morphology and more reduction in the oxygen functionality (C-O, C=O, O-H) of the synthesized sample of reduced graphene oxide (rGO). These results were indicative of their suitability for tunable fluorescence and catalytic activity. Hence the samples were screened for their efficiency in the degradation of organic dyes and chlorophenols. The results were satisfactory under the given experimental conditions. The results of the catalytic study ultimately provided a unique approach to the fabrication of catalyst for industrial wastewater treatment. The tunable luminescence study of assynthesized rGO can be further investigated for bioimaging of healthy and cancer cells in cell diagnosis and biomedical applications.

Subject: Application of Fabricated Sequencing Batch Reactor and Biofilm Sequencing Batch Reactor to Treat Dairy Wastewater
Keywords: Sequencing batch reactor, Biofilm sequencing batch reactor, Dairy industry wastewater, biosludge, Biofilm carrier
Abstract: The dairy industry is observed as one of the furthermost polluting industries. While processing 1 L of milk, 2-10 L of wastewater is generated. In India, around 286 large and small-scale dairy industries generate plenty amount of wastewater. The cyclic operation of fabricated sequencing batch reactor (SBR) curtails various parameters, such as BOD, COD and turbidity and were found to be 85.78%, 76.77% and 83.21%, respectively at 10 hr. As the detention time increases, BOD, COD and turbidity reduces. The fabricated sequencing batch reactor was modified by adding plastic media at the bottom of the reactor tank as a biofilm having a surface area of 2.7 m2. The main purpose of biofilm is to enhance the efficacy and bio-sludge superiority by increasing the bio-sludge in the process. The efficacies of removal of parameters were enhanced by using the biofilm sequencing batch reactor (BSBR) reactor under the high organic loading of 1340 g BOD5/m3 day. The COD removal of 89.3%, BOD5 removal of 83%, total Kjeldahl nitrogen (TKN) removal of 59.4% and oil and grease removal of around 82.4% was observed. Under the same high organic loading, curtailment of parameters was less in conventional sequencing batch reactor (SBR) [removal of COD- 87.0%, BOD5– 79.9%, TKN- 48.7% and oil and grease- 79.3%].

Abstract: The growing events of air pollution over the last decade have made implementing preventative measures a need more than a caution. An effective air quality forecasting system is the backbone of all measures. A detailed global literature review identifies statistical and ensemble models to be more efficient for forecasting problems. This study aims at experimentally analyzing 10 machine learning models on predicting PM2.5, PM10, SO2, CO, NO2 and O3 for developing a custom air quality forecaster for Delhi, India. The performance of all models was compared individually for each pollutant prediction using evaluation metrics, such as RMSE, MAE and MedAE. Based on experimental evidence, we conclude that a timeseries based deep neural network model performs best in the given scenario and can be explored further to create a custom air quality forecasting framework.

Subject: Construction of a medium for Pseudomonas fluorescens from Local Resource and its Trial Application as a Biopreservative
Keywords: Pseudomonas fluorescens, Agricultural wastes, biopreservative, Fruits, Vegetables, environment
Abstract: Pseudomonas fluorescens is a widely dispersed plant growth promoting rhizobacteria. It is not a human or plant pathogen and is found in soil, water, plants and other moist environments. This organism has already been used as a biocide against various fungi and bacteria in agricultural fields [1]. It has lots of biocontrol properties, like antibiotics, enzymes and siderophore productions. Due to its siderophore production its pyoverdine pigment fluoresces under UV light. This study was conducted mainly to construct a media with the cheapest local resource or agricultural waste and also to find its application as a biopreservative. The raw materials required for the construction of medium were agricultural wastes, such as rice husk, rice straw, wheat husk, peanut waste, dried cow dung and then coconut water, whey water and vermicompost. Then these four combinations were inoculated from the mother inoculum and their growth was checked by serial dilution and spread plate technique. Then these cultures were applied to apples, tomatoes, curry leaves and betel leaves by dip inoculation method. The keeping qualities of these vegetables were checked till the control items were rotten under laboratory conditions approximately for about 7 days. The physiological characteristics were good and fresh in the preserved items for 7 days but decayed on the control products. Thus, the first step towards the application of P. fluorescens as a biopreservative was successful.

Subject: Geoelectrical Sounding for Aquifer Characterization in and around Nandgao, Majan, Singrauli District, Madhya Pradesh, India
Keywords: Groundwater, Aquifer, Vertical electric sounding, Schlumberger, Ipi2win software
Abstract: Ten geo-electrical soundings using Schlumberger electrode configuration were used to evaluate aquifer geo-electric characteristics in the parts of Nandgao, Majan, district Singrauli, M.P., India. SSR MP-1, a digital resistivity meter, was used for ten vertical electric sounding (VES) sounding with a minimum of 10 m to a maximum of 200 m current electrode (AB) spacing and locating the exact position of VES stations global positioning system (GPS) was used. The IPI2win and win resist software was used for data interpretation, which revealed 3 to 4 subsurface layers comprising the top alluvial soil, sub-soil to fine-grained sandstone, fine-grained sandstone to fractured or weathered sandstone and basement rocks. The resistivity of these strata ranged from 9.55-59.51 Wm, whereas the depth ranged between 0.42-63.91 m. Transverse resistance and longitudinal conductance calculated from the aquifer resistivity and thickness varied from 102.14-4357.44 Wm2 and 0.08-1.02 Siemens, respectively. Also, aquifer resistivity and porosity ranged from 26.95-93.68 Wm and 53-92%, respectively. The low value of transmissivity at VES location no. 2, 3, 5, 8 correspond to low borehole yields and high at VES location no. 1, 4, 6, 7, 9, 10 correspond to high borehole yields. The value of overburden protection capacity is low at VES location no. 1, 2, 3, 5, 7, 8 and moderate at VES location 6, which means aquifers contaminants are more vulnerable in these areas. In contrast, at VES location 4, the aquifer protection capacity is high, indicating that the aquifer in these regions is well protected. However, a more significant portion of the study area has a lower value of protective capacities which reveals a more substantial part of the study area is susceptible to contaminants. In general, all of the places may be used to extract groundwater at moderate depths.

Keywords: Water use efficiency, Cropping pattern, Yield, Irrigation, Paddy, Cuddalore district, Water
Abstract: A suitable cropping pattern and irrigation strategy are essential for optimizing winter paddy yield and water use efficiency (WUE). The study aimed to evaluate the impact of cropping pattern and irrigation frequency on grain yield and WUE of winter paddy. During the 2018-2019 and 2019-2020 winter paddy growing seasons in the Vellar river basin at Cuddalore, the effects of cropping patterns and irrigation frequencies were determined on tiller number, paddy grain yield and WUE. The two cropping patterns tested were wide-precision and conventional-cultivation. Each cropping pattern had three irrigation regimes: irrigation (120 mm) at the jointing stage; irrigation (60 mm) at both the jointing and heading stages and irrigation (40 mm) at the jointing, heading, and milking stages. In our study, tiller number was significantly higher in the wide-precision cropping pattern than in the conventional-cultivation cropping pattern.

Subject: Effect of Organic Dust on Health of Pounding Mill Workers in Southern Maharashtra, India
Keywords: Dry chilli dust, Forced vital capacity, Forced expiratory volume, Peak expiratory flow rate, Pulmonary impairment, Pounding mill
Abstract: Chattani making is one of the common small-scale household occupations in Kolhapur city and around in western part of Maharashtra. It requires grinding of dry chillies and spices in pounding mill. The persons involved in this occupation may get exposed to organic dust which is associated with increased prevalence of respiratory symptoms and reduced lung function in human beings. Present study was carried out to investigate the effect of such exposure on the workers’ lung function and respiratory symptoms in pounding mills in Kolhapur city. Spirometry measurements of forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and peak expiratory flow rate (PEFR) were performed on 50 workers (35 females and 15 males) and 50 clinically normal (30 females and 20 males) served as control. Significant differences in FVC, FEV1 and PEFR were observed between the two groups for exposed and control populations as well as both in male and female populations. In addition to the decrease in spirometry values, the workers also reported higher prevalence of respiratory symptoms compared to controls. Therefore, the study suggests that exposure to organic dust in the pounding mills leads to an increased prevalence of respiratory symptoms and impaired lung function.

Abstract: Dissolved oxygen (DO) values in Bang Pakong river located in the east of Thailand were determined by multiple regression analysis. The collected data was split into 2 sets to cogitate which were training and validation sets. The stations of water quality monitoring for each set were breakdown into 4 periods: January-March, April-June, July-September and October-December. The prediction of DO in each period using data in the first set were remarkably achieved as 4 equations with the subsequent regression standard errors of 0.7342, 0.4349, 0.6436 and 0.4319 as well as the adjusted coefficients of determination of 0.3760, 0.8670, 0.2480 and 0.7320, respectively. The prediction accuracy was definitely measured by 4 performance indexes: mean absolute percentage error, mean absolute error, root mean squared error and mean squared error in each period (1st period: 0.1416, 11.0695, 1.5781, 2.4905; 2nd period: 0.2882, 9.7404, 1.3987, 1.9562; 3rd period: 0.2933, 8.6648, 1.3806, 1.9060; 4th period: 0.2454, 6.3330, 0.8890, 0.7903), accordingly applying data in the second set.

Abstract: The present study aims to assess groundwater quality in Jodhpur city by using geospatial and statistical analysis methods. Groundwater samples in the study area were collected and various groundwater quality parameters were determined. The geospatial analyst tool of ArcGIS software was employed to prepare the spatial distribution pattern of the groundwater quality parameters. The spatial distribution maps revealed that the groundwater in the area has fluoride and nitrate concentration lying beyond the permissible limits. Mostly the southeast part of the city has deteriorated groundwater quality. A weighted average statistic, WQI was estimated which considers the combined effect of the water quality parameters. The exercise yielded useful results. The results showed that 33% of the groundwater samples had good water quality and nearly 28% of the groundwater samples had very low groundwater quality which was unsuitable for drinking. WQI distribution map also revealed that the southeast part of the city has deteriorated groundwater quality. The deteriorated groundwater quality in this area could be attributed to the leaching of contaminants into the aquifer because of the improper disposal of industrial effluents.

Subject: Possibility of using Date Palm Fibers for the Removal of Metallic Trace Elements (Lead, Copper and Zinc) in an Aqueous Solution
Keywords: Adsorption, Water, Date palm fibers, Kinetics, Heavy metals
Abstract: This study was carried out to examine the adsorption capacity by using date palm fibers (DPF) for the removal of heavy metals from aqueous solution using beach tests. In the adsorption process, the effects of contact time, pH, initial concentration and adsorbent quantity were investigated. The results demonstrated that the biosorption capacity of heavy metals by DPFs was in the following order: Pb > Cu > Zn. And that the adsorption efficiency increases rapidly and that the optimum removal efficiency was reached within 25 min. The Langmuir model describes well the adsorption isotherms. The value of RL in the present study was less than one, indicating that the adsorption of the metal ion on the DPF is favourable. After treatment of the aqueous solution with DPF, a decrease in the levels of heavy metals in the solution was observed, with 98.60% for lead, 93.11% for copper and 83.66% for zinc. Date palm fibers are a promising environmental material that can be used without specific treatment and are economically viable for removal of heavy metals from wastewater.

Keywords: Rhizosphere, Sewage, Loading rate, Macrophytes, Contaminants, Efficiency
Abstract: Wastewater treatment in semi-natural systems is a technique that can be applied to natural wetlands such as swamps, medicinal plants and paddy fields, ponds, man-made lagoons, etc. Constructed wetlands especially the marsh areas are equipped for wastewater treatment. Man-made wetlands have various basic shapes with different flow characteristics. The positive response zone of artificial wetlands is the root zone (rhizosphere). This is where physio-chemical and biological processes take place due to the interaction of plants, microorganisms, soil and pollutants. In this study, chemical parameters of the sewage wastewater were analyzed and found contaminants are present in that wastewater. For reducing the contaminants of the sewage wastewater, a wetland was constructed using the plant Canna indica. Treatment efficiency varied according to changes in the hydraulic loading rate and temperature applied in the wetland. The plant species results show that the removal efficiency of the Canna indica for BOD, COD, SO4 and Cl– were 59.9%, 61.2%, 49.5% and 48.2%, respectively. The wastewater obtained through wetland construction is within the standard limit so wetland construction using Canna indica reduced the risks to the water bodies as well as to the environment.

Subject: Experimental Study of Biological Nitrate Removal Performance in Semi-Arid Regions: Effects of Woodchips and Hydraulic Retention Times
Keywords: Agricultural wastewater, biological process, nitrate reduction, Urmia lake basin
Abstract: Increasing fertilizer application to compensate for nutrient deficiency and ensure food security has caused leaching of more nitrate through sub-surface drainage and the spread of eutrophication in aquatic ecosystems. Woodchip bioreactors are a well-known method for removing nitrate from agricultural effluents. However, there is not enough knowledge about the performance of native woodchips in semi-arid ecosystems. 9 treatments, including 3 woodchips and 3 hydraulic retention times (HRTs) of 5, 12 and 24 hr were studied in 3 repetitions. Studied woodchips, walnut, beech and poplar were chosen from native trees of Urmia lake basin, known as a semi-arid region. The results disclosed that the HRT and woodchip significantly affected the nitrate removal rate (P<0.05). Walnut and beech woodchips had the highest and lowest nitrate reduction capability, respectively. The study showed an increase of about 16% in the nitrate removal efficiency in all woodchips due to an increase in the HRT from 5 to 12 hr. There were no significant differences between the HRTs of 12 and 24 hr (P>0.05). The results of this study confirm the desirable performance of walnut woodchip and 12 hr HRT in nitrate removal under semi-arid conditions.

Subject: A Study on Degradation of 1-Ethyl-3-Methylimidazolium Chloride and 1-Butyl-3-Methylimidazolium Chloride by Fenton’s Process and Optimization using Response Surface Methodology
Keywords: Imidazolium-based ionic liquids, Degradation, Fenton’s oxidation, Central composite design, Response surface methodology
Abstract: In this study, the process optimization was carried out by the application of response surface methodology (RSM) for the degradation of ionic liquids, namely 1-ethyl-3-methylimidazolium chloride (EMIMCl) and 1-butyl-3-methylimidazolium chloride (BMIMCl) in an aqueous solution using Fenton’s oxidation process. Experiments were designed using central composite design (CCD) of response surface methodology (RSM). The oxidant dosage (H2O2), the dosage of catalyst (Fe+2) and pH were selected as three independent input operating variables. The goodness of fit of the model was measured using the regression coefficient (R2) and the adjusted regression coefficient (R2adj). The R2 values of the model were 0.9564 and 0.9270 for EMIMCl and BMIMCl, respectively whereas the R2adj values were 0.9891 and 0.9817 for EMIMCl and BMIMCl, respectively. These values indicate a good fit for the model. An average maximum TOC degradation of EMIMCl (83.68%) and BMIMCl (73.54%) were calculated. The good agreement between the predicted values and the experimental values confirms the validity of the model for simulating the degradation of EMIMCl and BMIMCl by the Fenton oxidation process.

Keywords: Supply chain management, Green supply chain management, Structural equation modeling (SEM), Lean supply chain management, Operational performance
Abstract: The global environmental challenges have forced automobile manufacturing firms to implement practices that will reduce their impact on the environment. Over the years eco-friendly concepts have been developed to shift from traditional supply chain management to Green Supply chain management. The current paper attempts to study the Green Supply chain practices adopted by automobile manufacturing firms and their impact on lean supply chain management and the overall performance of the organization. Quantum surveys have been done across various Automobile Organizations, with a sample size of 360 respondents for various automobile organizations. A good model fit was achieved that shows Green Supply chain activities have an impact on lean performance and the overall performance of an organization. The findings of the studies can help the researcher, experts, and practitioners to study and implement the green supply chain practices in the organization which would further support in reducing environmental issues which are major challenges for developing countries.
