Adsorption of an emerging contaminant (primidone) onto activated carbon: kinetic, equilibrium, thermodynamic, and optimization studies Image Adsorption of an emerging contaminant (primidone) onto activated carbon: kinetic, equilibrium, thermodynamic, and optimization studies( Environment Monitoring and Assessment)
(,,,,Year : 2019)

The current study addresses the removal of an emerging environmental contaminant (primidone) in batch adsorption experiments using commercial-grade powdered activated charcoal (PAC). The experiments for the removal of primidone were performed to identify the effect of various adsorption parameters. The second-order rate expression best represented the adsorption kinetics data. The Freundlich isotherm equation was best fitted to the experimental adsorption data at equilibrium for removal of primidone using PAC. The values for change in entropy (ΔSo) were positive, which indicates that the degree of freedom of the process increases. The negative values of change in enthalpy (ΔHo) and change in Gibb’s free energy (ΔGo) indicate that the physical adsorption is a dominant phenomenon, and the process is feasible and spontaneous. The negative value of ΔHo also represented the exothermicity of the adsorption process. The Taguchi optimization technique calculated the influence of variation of different process parameters, viz., initial pH (pH0), PAC dosage (m), initial adsorbate concentration (C0), solution temperature (T), and process contact time (t), on the removal of primidone by adsorption from aqueous solution. Each of the above parameters was examined at three levels to study their effects on the adsorptive uptake of primidone using PAC (qe, mg g−1), and the optimum value necessary to maximize qe was determined. The findings from the ANOVA indicate that the PAC dose (m) is the most notable parameter contributing 62.16% to qe and a 71.96% to the signal to noise (S/N) ratio data, respectively. The confirmation experiments performed at the optimum parameter condition validated the applicability of the Taguchi design of experiments. The percent removal and adsorptive uptake at the optimal condition were 86.11% and 0.258 mg g−1, respectively.

Role of fluoride induced epigenetic alterations in the development of skeletal fluorosis Image Role of fluoride induced epigenetic alterations in the development of skeletal fluorosis(Ecotoxicol Environ Saf. )

Oxidative stress is reported to negatively affect osteoblast cells. Present study reports oxidative and inflammatory signatures in fluoride-exposed human osteosarcoma (HOS) cells, and their possible association with the genes involved in osteoblastic differentiation and bone development pathways. HOS cells were challenged with sublethal concentration (8 mg/L) of sodium fluoride for 30 days and analyzed for transcriptomic expression. In total, 2632 transcripts associated with several biological processes were found to be differentially expressed. Specifically, genes involved in oxidative stress, inflammation, osteoblastic differentiation, and bone development pathways were found to be significantly altered. Variation in expression of key genes involved in the abovementioned pathways was validated through qPCR. Expression of serum amyloid A1 protein, a key regulator of stress and inflammatory pathways, was validated through western blot analysis. This study provides evidence that chronic oxidative and inflammatory stress may be associated with the fluoride-induced impediment in osteoblast differentiation and bone development.

Noise is one of the most significant sources of environmental pollution in metro cities. Traffic noise plays an important role to contribute to ambient noise pollution. Noise pollution monitoring was carried out using sound level meter mounted on the cycle with the help of mould fixed on it. Cycle is a noiseless mode of transport and therefore, it was used for noise monitoring over 700 locations in Nagpur City. Noise levels were recorded at each location for 5 min during peak rush hours of traffic in the morning and in the evening at an interval of 1 s leading to around 300 readings each. Noise indices like Leq, L90, L10, Lmax and Lmin were calculated for noise level data analysis. TNI was also determined for analysis of traffic noise on intersections of roads. Equivalent noise levels were transferred into the Geographic Information System (GIS) and spatial analysis tool was used to create spatial and strategic noise maps. Based on the maps, it is revealed that noise levels are exceeded all over the city with respect to ambient noise standards. It was experienced that intersections of roads during peak rush time are very noisy due to honking. The study recommends the noise monitoring through cycle-mounted sound level meter since it covers unapproachable sites, more coverage in the city that helps in identifying hotspot area of concern for noise abatement strategies and planning.

Review of processes controlling Arsenic retention and release in soils and sediments of Bengal basin and suitable iron based technologies for its removal Image Review of processes controlling Arsenic retention and release in soils and sediments of Bengal basin and suitable iron based technologies for its removal
(Komal Kalawapudi, Sudheer Salana, Ritesh Vijay ,8,,358-367,Year : 2019)

Arsenic in the soil environment has gained renewed interest because of the emerging cognizance that arsenic poisoning is a global concern. Groundwater in the Bengal Basin is significantly polluted by naturally occurring arsenic (As), a toxic metalloid, which adversely affects human health and among the countries facing As contamination problems, India and Bangladesh are the most affected. In soils and sediments, arsenic is often associated with Fe(III) (hydr)oxides and multiple processes/reactions govern its release into groundwater, including abiotic or biotically mediated oxidation-reduction and ligand exchange reactions. Reductive dissolution of arsenic-bearing Fe(III) (hydr)oxides and As(V) reduction to As(III) are the two main mechanisms controlling arsenic partitioning in soils, sediments and groundwater. Even though arsenic reduction is favourable over a wide range of conditions, Fe(III) reduction in nature is dependent on the biotic systems. This review reflects the current state of research for the understanding of arsenic in the soil environment with an emphasis on iron based technologies for its removal. It attempts to collate all the relevant literature such that it can be a useful resource for researchers or policy makers to help recognize and explore useful treatment options.

Zooplankton diversity as indicators of pollution in warm monomictic Dal Image Zooplankton diversity as indicators of pollution in warm monomictic Dal(Sustainable Water Resources Management)
(Dilip Meshram, D Catherine, N. Badhe, Snehal Khedkar, Ritesh Vijay Tapas Nandy ,Vol(4) Issue (4) Pages(897?904),,,Year : 2018)
The study aimed to assess the zooplankton diversity in Dal?Nigeen lake located in Srinagar, India. Zooplankton is a secondary producer which acts as the intermediate link between phytoplankton and fish in aquatic environment. Zooplankton diversity in the lake was monitored during autumn 2012 and summer 2013. Among zooplankton single species belonging to protozoa, 11 species to rotifera, 3 species to cladocera, and 2 species with single larval stage belonging to copepod were identified. Percent composition of zooplankton communities revealed that rotifera was the most dominant group followed by copepoda in summer, while rotifera was the most dominant group followed by cladocera in autumn season. The Shannon?Wiener diversity index (SWI) in summer varied from 1.29 to 3.63 and from 1.43 to 3.67 in autumn indicating moderate-to-good level of zooplankton diversity in the lake and low-to-medium impact of organic pollution from the anthropogenic activities. The study indicates that species abundance was lower in summer as compared to autumn season which may be due thereby to variation in environmental characteristics of the lake water.

(,,,,Year : 2018)

Waste-to-Energy is emerging as an attractive business option due to huge quantities of waste being generated today. Landfilling is now being viewed as environmentally unfavourable because it contributes to GHG emissions and also requires huge areas of land, which may not be possible in small countries or countries with high densities of population. Moreover, large fractions of waste generated have huge energy potential which might get lost if sent to landfill. Waste-to-Energy business is still in its early stages in many parts of the world and the business models are yet to be optimised for successful option. In this chapter, business models practised in various parts of the world in Waste-to-Energy business have been explored and both their financial and environmental aspects have been dealt with. The drivers of such businesses and the problems associated with them have been studied using examples of practices in various countries. One major conclusion is that there is a huge potential of revenue through energy generation from waste but most of the countries suffer from poor waste management practices and little or no incentives to establish such businesses. There exist a variety of models which can be implemented both in poor countries such as those of Africa and rich countries such as those of Europe. Government regulations, laws, incentives and support are highly important to the growth of Waste-to-Energy businesses and play a major role in choosing the right kind of business model. The best business model for a particular region should be designed considering these factors as well as the environmental impacts.

Genomically Defined Paenibacillus polymyxa ND24 for Efficient Cellulase Production Utilizing Sugarcane Baogasse as a Substrate Image Genomically Defined Paenibacillus polymyxa ND24 for Efficient Cellulase Production Utilizing Sugarcane Baogasse as a Substrate(Appl Biochem Biotechnol )
(Varsha Bohra, Hiitesh Tikariha ,,,,Year : 2018)

Cellulolytic bacteria from cattle rumen with ability to hydrolyze cellulose rich biomass were explored. The study selected Paenibacillus polymyxa ND24 from 847 isolates as the most potent strain, which can efficiently produce cellulase by utilizing sugarcane bagasse, rice straw, corn starch, CMC, and avicel as a sole carbon source. On annotation of P. polymyxa ND24 genome, 116 members of glycoside hydrolase (GH) family from CAZy clusters were identified and the presence of 10 potential cellulases was validated using protein folding information. Cellulase production was further demonstrated at lab-scale 5-L bioreactor exhibiting maximum endoglucanase activity up to 0.72 U/mL when cultivated in the medium containing bagasse (2% w/v) after 72 h. The bagasse hydrolysate so produced was further utilized for efficient biogas production. The presence of diverse hydrolytic enzymes and formidable cellulase activity supports the use of P. polymyxa ND24 for cost-effective bioprocessing of cellulosic biomass.
