Utilization of layered double hydroxides (LDHs) and their derivatives as photocatalysts for degradation of organic pollutants(Environmental Science Pollution Research)
(Sukdeb Pa Prakash Bobde, Ravi Kumar Patel, Deepak Panchal, Abhishek Sharma, Amit Kumar Sharma, Rita S. Dhodapkar,,,,Year : 2021)
|
|
Direct or indirect discharge of wastes containing organic pollutants have contributed to the environmental pollution globally. Decontamination of highly polluted natural resources such as water using an effective treatment is a great challenge for public health and environmental protection. Photodegradation of organic pollutants using efficient photocatalyst has attracted extensive interest due to their stability, effectiveness towards degradation efficiency, energy, and cost efficiency. Among various photocatalysts, layered double hydroxides (LDHs) and their derivatives have shown great potential towards photodegradation of organic pollutants. Herein, we review the mechanism, key factors, and performance of LDHs and their derivatives for the photodegradation of organic pollutants.

Novel photocatalytic techniques of Organic dye degradation in water(Photocatalytic Degradation of Dyes)
(Sukdeb Pal Deepak Panchal, Abhishek Sharma,Vol(1),Pages(808),,,Year : 2021)
|
|
Around 11 million tons of water is polluted per year and dye stuff industries contribute ?20% of the total industrial water pollution. Dyes are the recalcitrant pollutants in water because of their complex aromatic structure, high molecular weight, stability, degradation resistance, carcinogenic and mutagenic nature, and tendency to screen sunlight inhibiting photosynthetic reactions. Adsorption and filtration (reverse osmosis using membranes) have always been considered as efficient and economic dye removal methods that can be effortlessly scaled-up in wastewater treatment plants. However, due to high stability and recalcitrant nature of organic dyes these general treatment methods often suffer from low level of efficiency. Given these complexities, in past few decades photocatalytic degradation has grabbed much attention for organic dye removal reflecting its ability for complete mineralization.

Photo-Induced Synthesis of Coral-Like Hierarchical Ag(Chemistry of Materials)
(Deepak Panchal, Sukdeb Pal,Vol(33),Issue(16),Pages(6501-6513),,,Year : 2021)
|
|
Herein, we report, for the first time, rapid and facile photo-induced synthesis of hierarchical Ag?Fe bimetallic nanostructures with tailorable morphologies based on variation of Fe2+ concentrations at the submillimolar level. The synthesis methodology relies on the photo-oscillation of the Fe(II)?Fe(III)?Fe(II) system in the aqueous medium, leading to reduction of Ag+ to Ag0 nanoparticles ,wherein Ag0 nanoparticles are stabilized in an Fe-oxide framework. The morphology of the product is tailored from scattered to prominent coral-like nanostructures by simply varying the Fe2+ concentrations at the submillimolar level. The developed method eliminates the essential need of presynthesized precursor metal nanoparticles, toxic templates or surfactants, organic solvents, and sophisticated instrumentations or stringent reaction conditions.

Potential of Agro-Products in the Green Synthesis of Nano-Metallopharmaceuticals(Nanotechnology in Sustainable Agriculture)
(Deepak Panchal, Rita S Dhodapkar, Sukdeb Pal,Pages(117-138),,,Year : 2021)
|
|
Recent advancements in nanotechnology have received more attention due to their safer and effective pharmacology and medicinal applications. Compared to traditional drugs, nano-metallopharmaceuticals offer a better-targeted approach to minimize off-target effects and, thus, undesirable side effects. Despite many potential applications, growing concerns have been expressed for their safe production to reduce antagonistic human health effects. The production of metallopharmaceuticals can be grouped into three classes ? chemical, physical, and biological. However, reactants often used in chemical procedures are toxic, and their remnants, if they exist in nanomedicine, can induce systemic toxicity. Similarly, physical methods are expensive, with high power consumption, and they require a large space.

Heterolayered TiO2@ layered double hydroxide-MoS2 nanostructure for simultaneous adsorption-photocatalysis of co-existing water contaminants(Applied Surface Science)
(Deepak Panchal, Abhishek Sharma, Prasenjit Mondal, Om Prakash, Sukdeb Pal,Vol(553),Pages(149577),,,Year : 2021)
|
|
The highly ordered heterolayered-nanostructure TiO2@Layered double hydroxide/Molybdenum disulfide (TiO2@LDH/MoS2; T@L/M) is formed by electrostatically-driven self-assembly of positively charged TiO2-dispersed-LDH layers (T@L) and negatively charged MoS2 nanosheets. TiO2 are incorporated in-situ across the LDH during synthesis yielding exfoliated TiO2-dispersed-LDH layers (T@L). Prior to MoS2 assembly, its interlayer spacing is enlarged and defects are created in basal-plane exposing sulfur-rich sites. Visible-light-active MoS2 and TiO2 synthesized heterostructure extending the T@L/M photoactivity in visible spectrum (2.92 eV) for enhanced degradation capacity

Adsorption of five emerging contaminants on activated carbon from aqueous medium: kinetic characteristics and computational modeling for plausible mechanism(Environmental Science and Pollution Research)
(Archana Rao, Anupama Kumar, Rita Dhodapkar, Sukdeb Pal,Vol(28),Issue(17),Pages(21347-21358),,,Year : 2021)
|
|
Pharmaceuticals and personal care products (PPCPs) do not have standard regulations for discharge in the environment and are categorized as contaminants of emerging concern as they pose potential threats to ecology as well as humans even at low concentrations. Conventional treatment processes generally employed in the wastewater treatment plants are not adequately engineered for effective removal of PPCPs. Identifying cost-effective tertiary treatment is therefore, important for complete removal of PPCPs from wastewater prior to discharge or reuse. Present study demonstrates adsorption using granular-activated carbon (GAC) as a possible tertiary treatment for simultaneous removal of five PPCPs from aqueous media. Adsorbent was characterized in terms of morphology, surface area, surface charge distribution, and presence of functional groups.

In India, sewage (partially-treated/ untreated) is randomly used for irrigation because of easy availability and presence of residual organics and nutrients. However, data on the occurrence of contaminants of emerging concerns (CECs) such as pharmaceuticals and personal care products (PPCPs) and antibiotic resistant bacteria (ARB) and antibiotic resistant genes (ARGs) in sewage is scarce in Indian perspective. Herein, for the first time, we present a quantitative contamination profiling of selected PPCPs and antibiotic resistance in untreated and biologically-treated sewage from three different sewage treatment plants, located in northern and central part of India. Profiling of PPCPs were done using LC-ESI-MS/MS whereas antibiotic resistance was analyzed using gradient PCR and qPCR techniques.

SARS-CoV-2: fate in water environments and sewage surveillance as an early warning system(Water Science and Technology)
(Deepak Panchal, Purusottam Tripathy, Om Prakash, Abhishek Sharma, Sukdeb Pal,,,,Year : 2021)
|
|
Coronavirus disease has emerged as one of the greatest threats to human well-being. Currently, the whole world is fighting against this pandemic that is transmitted either through exposure to virus laden respiratory or water droplets or by touching the virus contaminated surfaces. The viral load in feces of an infected patient varies according to the severity of the disease. Subsequent detection of viral genome (SARS-CoV-2) in human feces and sewage systems is an emerging concern for public health. This also dictates to reinforce the existing sewage/wastewater treatment facilities. Rapid monitoring is the key to prevent and control the current mass transmission. Wastewater-Based Epidemiology (WBE) is a potential epidemiology tool that can act as a complementary approach for current infectious disease surveillance systems and an early warning system for disease outbreaks

Transmission of novel coronavirus (SARS-CoV-2) in humans happens either through airway exposure to respiratory droplets from an infected patient or by touching the virus contaminated surface or objects (fomites). Presence of SARS-CoV-2 in human feces and its passage to sewage system is an emerging concern for public health. Pieces of evidence of the occurrence of viral RNA in feces and municipal wastewater (sewage) systems have not only warned reinforcing the treatment facilities but also suggest that these systems can be monitored to get epidemiological data for checking trend of COVID-19 infection in the community. This review summarizes the occurrence and persistence of novel coronavirus in sewage with an emphasis on the possible water environment contamination

Assessment of Environmental Water Security of an Asian Deltaic Megacity and Its Peri-Urban Wetland Areas(Sustainability)
(Subham Mukherjee, Pradip K. Sikdar, Sukdeb Pal, Brigitta. Sch?tt,Vol(13),Issue(5),Pages(2772),,,Year : 2021)

Achieving urban water security requires sustaining the trade-offs between the exploitation of water/environmental resources and ecosystem services. This achievement not only reduces the pollution and contamination in the environment, level of water stress, but also secures good ambient water quality and future for people?s well-being and livelihoods. Changes in land use and land cover and growth of impervious structures can immediately generate severe ecological and social issues and increase the level of natural or manmade risks, affecting the condition of ecosystem services within and in the vicinity of an urban region. As a result of these transformations and further exploitation, due to the growing anthropogenic pressure, surface water and groundwater quality can be deteriorated compared to ambient water quality standards (for both chemical and biological pollutants). Based on land use and land cover (LULC) data retrieved from remote sensing interpretation, we computed the changes of the ecosystem service values (ESV) associated with the LULC dynamics, water quality and, finally, urban water security during the pre-and post-monsoon periods of 2009, 2014 and 2019 in Kolkata, an Asian deltaic megacity, and its peri-urban wetlands named East Kolkata Wetlands (EKW). The area under wetlands reduced comprehensively in 2009?2019 due to the conversion of wetlands into various other classes such as urban settlement, etc. The quality of surface water bodies (such as rivers, lakes, canals and inland wetlands) deteriorated.

The environment can be well-defined as all forms that surround both living elements (such as humans or animals, fishes and birds) as well as non-living elements, itself classified as both moving (such as air and water) and non-moving (such as mountains and forests). Human activities do interact with the bio-physical environment in a multifaceted manner connecting different geographical levels. The existence of all living forms on this planet gradually evolved to build a healthy and well-balanced environment throughout the space and time. The new economic demand should operate in a way that shields the biophysical environment to maintain the balanced and sustainable growth both at the present and in the future.

Solid Waste Characterization and Treatment Technologies in Rural Areas: An Indian and International Review(Environmental Technology and Innovation )
(Akash Patwa Divyesh Parde Ritesh Vijay Rakesh Kumar,,,,Year : 2020)
|
Solid waste generation and treatment become one of the main concerns for the rural area. This article reviews the solid waste composition and various solid waste treatment technologies in the rural areas of India and other countries. The solid waste generated in a rural area containing more than 50% of organic waste and rest inorganic. Waste generation rate is 0.3-0.9 kg/capita/day in various rural areas of different countries. Agriculture waste and animal waste are the major components of the organic fraction. Because of the organic nature of waste, composting is the most feasible technology of treating solid waste in the rural area. The review article also focused on various factors which may affect the process of composting and helpful for selecting composting technology as moisture content, C/N ratio, turning frequency, particle size, aeration rate, and temperature. Optimum values of these parameters are found that the optimum moisture content is (45%?60%), suitable temperature (45?70 ?C), turning frequency (7?15 days/turning) and C/N ratio (25?30). This paper also contains various treatment technologies for the organic solid waste which are based on composting and anaerobic digestion.

Substrates properties play an important role in immobilization of bio-organisms and hence in optimizing design of the bioreactor to maximize the performance. Highly flexible 3D printing process based on virtual Computer Aided Design (CAD) is used for producing honeycomb substrates with desired properties. Clay based honeycomb with square, triangular and hexagonal configurations are 3D printed in order to achieve substrates with pre-designed geometrical surface areas. Laboratory reactors were fabricated with engineered properties using 3D printed honeycombs and a combination of honeycombs and commonly used stones for performance evaluation. Additionally, reactor based on commonly used gravel stones also fabricated for sake of comparison of performance. In order to elucidate the performance, sewage mix was fed into the reactors and the space velocity of all the three reactors were maintained at 0.041 h?1. The sewage before and after treatment was tested for the performance markers such as pH, TSS, BOD and COD. Treated water met the stipulated standards prescribed by American Public Health Association with respect to all parameters studied. Though the difference in the performance of the reactors was marginal, with honeycombs a substantial reduction in the weight of the reactor can be accrued along with high mass transfer due to low pressure drop which can be attributed to the inherent higher surface to volume ratio. Further, by engineering the surface porosity of the honeycombs, it is possible reduce TSS as demonstrated in this study. These advantages offer flexibility in scaling up the reactors for larger capacities for de-centralized requirements.

Traffic noise prediction model of an Indian Road: An increased scenario of vehicles and honking(Environmental Science and Pollution Research)
(Chaitanya Thakre, Vijaya Laxmi, Ritesh Vijay, D. J. Killedar, Rakesh Kumar,,,,Year : 2020)
|
Noise is considered as an underrated and underemphasized pollutant in contrast to other pollutants of the environment. Due to the non-acute response of health effects, people are not vigilant towards consequences regarding noise pollution. The expansion of the transportation industry is contributing towards the increment in the public and private vehicular volume which causes an increment in noise pollution. For evaluation of respective scenario, the research study has been conducted on one of the minor roads of Nagpur, India; for 2 years, viz., 2012 and 2019. The study concludes an increment of 5–6 dB(A) in noise level, 4–6 times in honking, and 1.7 times in traffic volume. The study confirms increment in sound pressure by 65.9% and 81.9% for the year 2012 and 2019 during morning and evening sessions, respectively. Noise prediction model has also been developed for the abovementioned years, using multiple regression analysis, considering traffic volume, honking, and speed against noise equivalent level. Honking has been further characterized into honk by light and medium category vehicles as acoustical properties of horns vary with respect to category of vehicle and introduced into the noise prediction model. Noise prediction model for 2019 has predicted the noise level in a range of ? 1.7 to + 1.4 dB (Leq) with 84% of observations in the range of ? 1 to + 1 dB (Leq), when compared with observed Leq on the field. For proper management of noise pollution, a noise prediction model is essentially needed so that the noise level can be anticipated, and accordingly, measures can be outlined and executed. This increased noise level has serious impacts on human hearing capacity and overall health. Accordingly, noise mitigation preventive measures are recommended to control traffic noise in the urban environment.
