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.

Subject: Groundwater Quality Assessment of Jodhpur City Lying in Arid Zone of India
Keywords: Groundwater, Water quality parameters, Water quality index, GIS
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.

Subject: Onsite Wastewater Treatment using Artificially Constructed Wetland Planted with Canna indica
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.

Abstract: Noise pollution is one of the major problems facing the modern world at large due to economic growth, industrialization and uncontrolled urbanization. Exposure to high noise pollution levels has physiological (auditory) and psychological effects. The project aims to determine variations in noise level and pollution produced within the Oja Oba area in Ibadan, Oyo state, Nigeria. The environmental equivalent noise levels (Leq) were measured at 12 randomly selected spots within Oja Oba market in the morning and afternoon between September and October 2020 using an SW-524 LCD digital sound level meter. The meter was held at about 1.5 m above ground levels and 3 m from the noise source around each spot for 1/4 of an hour before readings were taken to ensure good area coverage, stability and uniformity in measurement. The average noise pollution level (Lnp) was calculated using a standard equation. The standard deviation of disease and area affected by noise pollution were 0.2 and 0.3589, respectively. The equivalent noise level in the market at the 12 selected points for working days and weekends ranged between 70-98 and 68-106 dBA, respectively. The average noise pollution level in the market varied from 87-128 dBA. These equivalent noise levels and average noise pollution for the Oja Oba market were computed. The obtained data can serve as baseline information for noise pollution modelling and control.

Keywords: Waste printed circuit boards, Auto-switch, Inverter, Bioleaching, Oxidising iron bacteria, Consortium, Copper
Abstract: Electronic equipment commonly known as e-waste is the fastest-growing solid waste in the world. E-waste is nowadays preferentially used for the recovery of metals from printed circuit boards (PCBs). The PCB is a significant part of all electronic waste, and it is a potential source of different metals, thus known as an urban mine. The study aimed to enhance the extraction of copper from pulverised waste printed circuit boards (WPCBs) using an iron-oxidising consortium from the inverter and auto-switch WPCBs. Microbial leaching is based mainly on the potential of microorganisms to generate lixiviants that mobilise metals from PCBs. Iron-oxidising bacteria generate ferric iron and protons that extract several metals in the aqueous phase. In this study, optimisation of various parameters was done. Optimised conditions for inverter WPCBs and auto-switch WPCBs showed more than 95% extraction of copper at pH 1.8 to 2.0, ferrous iron concentration from 6% to 8% and pulp density of 10%.

Abstract: The study of groundwater quality in Lingasugur taluk of Raichur district has resulted in a large hydrochemistry data which is here simplified with the water quality index (WQI) for better understanding of the overall quality parameters alongwith the categorized areal extent. A total of 116 groundwater samples have been collected in each season of pre-monsoon and post-monsoon to study the hydrochemistry as well as seasonal variation in the physico-chemical parameters. The collected groundwater samples were analyzed for physical characteristics, such as pH, EC and TDS alongwith the chemical major ions, like Ca2+, Mg2+, Na+, K+, Cl–, SO42-, HCO3–, CO32-, NO3– and F–. The correlation analysis has been carried out to understand the geochemical processing controlling groundwater geochemistry. The water quality index (WQI) values were categorized into six classes and mentioned the statistical data accordingly. The result suggests that the overall quality of the study area is suitable for irrigation and industrial use whereas only 6% and 4% of the water samples are suitable for drinking purposes during pre-monsoon and post-monsoon seasons, respectively. This study illustrates the usefulness of WQI and understanding the water quality along with the extent of the contamination.

Subject: Application of Mitscherlich-Bray Equation for Fertilizer Use in Barley Production in the Wolaita of Southern Ethiopia
Keywords: Barley, Nitrogen, Phosphorus, Potassium, Total value cost ratio
Abstract: The experiments were intended at three locations to formulate different levels of NPK fertilizers recommendations for barley based on the Mitscherlich-Bray equation at the Wolaita zone in southern Ethiopia. The experiments were laid out in randomized complete block design (RCBD) with factorial arrangements applying NPK with three replications. Treatments were levels of N (0.23 and 46, P, 0, 10, 20 and 30 and K, 0, 25 and 50 kg/ha) in all possible combinations. The theoretical maximum yield of barley was calculated by plotting log y vs 1/x (amount of nutrients applied). Fertilizer recommendations for various soil fertility levels and yield targets were developed and their validities were tested by conducting three field verification trials on the same soils. The results showed that although the general recommended fertilizer dose resulted in the highest yield of barley at all the locations, total value cost ratio and net revenue were lowest with this fertilizer treatment and maximum yield treatment was superior in terms of the economics of fertilizer. The model considers the interactions of N, P and K and soil properties adjusted potential yield of the region, which predicts crop yields from chemical soil characteristics, as an indicator of soil fertility.

Subject: Feasibility Studies on the Removal of Rose Bengal Dye through Electrolytic Degradation
Keywords: Rose Bengal, Advanced oxidation, Electro-Fenton, ANOVA, Genetic algorithm
Abstract: Removal of colour during the treatment of wastewater has always urged the scientific community to create sustainable, cost-saving and novel methods in recent times. The present study aims to study the feasibility of the removal of Rose Bengal dye from an aqueous solution through an electrolytic oxidation reaction. Zinc and carbon cathodes are placed in an electrolytic solution containing Fenton’s reagent and Rose Bengal dye ranging from concentrations of 4 to 12 ppm. The operational parameters like voltage (4.8 V, 6 V and 7.2 V), catalyst concentration (0.18 mM, 0.27 mM and 0.36 mM) and electrode selection were varied to determine the maximum removal efficiency. The combination of 4.8 V – 0.36 mM – 4 ppm presented a maximum removal efficiency of 92.97% for zinc electrode while the combination of 7.2 V – 0.36 mM – 4 ppm showed maximum removal of 94.99% for carbon electrode in Rose Bengal removal from aqueous solution. The results from the laboratory studies were interpreted with a variance analysis through ANOVA and regression equations with a desirability factor of more than 94% were obtained.

Subject: The Impact of Stubble Burning on Air Quality and Anaerobic Biogas Plants as a Viable Solution – An Opportunity Analysis for Punjab, India
Keywords: Satellite imagery, Stubble burning, Sustainable agriculture, Pollution, Biogas, Anaerobic digestion, Farmers
Abstract: Stubble burning and its resultant pollutants have adversely affected the environment and posed serious health hazards. It is very important to understand the situation from the farmer’s perspective and from the perspective of conserving the environment. In the present study, a critical analysis of stubble burning and its effects on the neighbouring city of Delhi has been done with the help of satellite imagery and simultaneously analysing the air quality index. The effect of pollutant dispersion on neighbouring areas has been studied at the time point when stubble burning takes place and over the following time intervals in the adjoining area. Furthermore, this study conducts an economic analysis of biogas plant establishment, biogas and biofertilizer generation from stubble and its sale. Thus, this study provides an opportunity analysis on how the stubble can be put to better use to produce utilizable cooking gas and fertilisers, which can directly benefit farmers, besides being economically and environmentally rewarding. The paper concludes with policy-related suggestions including setting up of corporative societies including the farmers as participants.
