Mitigation of Air Pollution and Carbon Footprint by Energy Conservation through CFLs: A Case Study(Journal of Environmental Science and Engineering (JESE))
(,53,1,65-74,Year : 2011)
|
Electricity consumption of compact fluorescent lamps (CFLs) is low, making them a useful tool for minimizing the rapidly increasing demand of electrical energy in India. The present study aims to project the likely electricity conservation in a scenario of complete replacement of existing Fluorescent Tubes (FTs) by CFLs at CSIR-NEERI (National Environmental Engineering Research Institute) vis a vis the financial repercussions and indirect reduction in emissions of greenhouse gases, eg CO, NO, CH, and other air pollutants, eg SO, NO, suspended particulate matter (SPM), black carbon (BC) and mercury (Hg) from coal fired thermal power plants. The calculations show that the Institute could save around 122850 kWh of electricity per annum, thereby saving approximately INR 859950/-(USD 1845386) towardselectricity cost perannum and would be able to minimize 4457908kg of Co-C'equivalent (over 100 year time horizon), 909 kg SO2, 982.8 kg NO, 9.8 kg of BC, 368.5 kg SPM, 18.4 Kg PM10 and 0.0024 kg Hg emissions per annum from a coal fired thermal power plant by conserving electricity at the institute level.

Non-Ferrous Metals in E-waste: Opportunities and challenges(18th International Conference on Research and Industrial Practices exclusive on Non-ferrous Minerals and Metals (ICNFMM 2014))
(Kalpana Tomar,,,,Year : 2014)
|
E-waste comprises of old, end-of-life electrical and electronic appliances which have been disposed of by their original users. E-waste contains many hazardous and toxic constituents that may negatively impact the environment and affect human health, if not properly managed. Also it contains valuable and precious material including the non-ferrous metals which can be a good source of business opportunities if being recovered and recycled. E-waste management system followed in developing countries faces many country specific issues viz. socio-economic conditions, lack of infrastructure, absence of appropriate legislations for E-waste, approach and commitments of the concerned, etc. The paper presents E-waste scenario in developing countries like India, potential of valuable non-ferrous valuable materials, recycling/recovery processes followed and their environmental and occupational hazards besides various challenges for E-waste management in developing countries like India. E-waste is viewed as a potentially valuable resource for precious and non-ferrous metals. Due to which, the management of E-waste, if properly carried out, is an opportunity as it is often called as “urban mining”.

Microbial capacities drive waste stabilization and resource recovery in environmental friendly processes. Depending on the composition of waste, a stress-mediated selection process ensures a scenario that generates a specific enrichment of microbial community. These communities dynamically change over a period of time while keeping the performance through the required utilization capacities. Depending on the environmental conditions, these communities select the appropriate partners so as to maintain the desired functional capacities. However, the complexities of these organizations are difficult to study. Individual member ratios and sharing of genetic intelligence collectively decide the enrichment and survival of these communities. The next-generation sequencing options with the depth of structure and function analysis have emerged as a tool that could provide the finer details of the underlying bioprocesses associated and shared in environmental niches. These tools can help in identification of the key biochemical events and monitoring of expression of associated phenotypes that will support the operation and maintenance of waste management systems. In this chapter, we link genomic tools with process optimization and/or management, which could be applied for decision making and/or upscaling. This review describes both, the aerobic and anaerobic, options of waste utilization process with the microbial community functioning as flocs, granules, or biofilms. There are a number of challenges involved in harnessing the microbial community intelligence with associated functional plasticity for efficient extension of microbial capacities for resource recycling and waste management. Mismanaged wastes could lead to undesired genotypes such as antibiotic/multidrug-resistant microbes.

Recent Advances in Copper Intercalators as Anticancer Agents
(Devi, C.S Thulasirm, B; Satyanarayana, S; Nagababu,P.
,,,,Year : 2017)
|
Copper is a part of various enzymes and helps them to function properly. It can be effectively used to produce promising anticancer drugs and presently, many studies are being pursued worldwide on the development of copper-based complexes as potential anticancer drugs. Herein, we briefly discuss the importance of reactive oxygen species in biological applications and copper(II) complexes as anticancer drugs. The anti-angiogenic properties of mono-nuclear copper(II) complexes have been demonstrated by in vivo chick embryo angiogenesis analysis. The plausible mechanism behind anticancer activity of these complexes is by the formation of excessive intracellular Reactive Oxygen Species (ROS). ROS is a composite term used for oxygen derivative non-radicals and free radicals of highly reactive components, that enhances the killing response of immune cells to microbial invasion. Previous reports have shown that ROS plays an important role as a messenger in cell cycling and normal cell signal transduction.

(P.V. Nidheesh, M. Zhou, M. A. Oturan
,197,, 210-227,Year : 2018)

Wastewater containing dyes are one of the major threats to our environment. Conventional methods are insuf?cient for the removal of these persistent organic pollutants. Recently much attention has been received for the oxidative removal of various organic pollutants by electrochemically generated hydroxyl radical. This review article aims to provide the recent trends in the ?eld of various Electrochemical Advanced Oxidation Processes (EAOPs) used for removing dyes from water medium. The characteristics, fundamentals and recent advances in each processes namely anodic oxidation, electro-Fenton, peroxicoagulation, fered Fenton, anodic Fenton, photoelectro-Fenton, sonoelectro-Fenton, bioelectro-Fenton etc. have been examined in detail. These processes have great potential to destroy persistent organic pollutants in aqueous medium and most of the studies reported complete removal of dyes from water. The great capacity of these processes indicates that EAOPs constitute a promising technology for the treatment of the dye contaminated ef?uents.

Screening of few aquatic floating plants for chromium phytoremediation(Journal of Environmental Technology, and Management)
(Chakraborty, R.,Mukherjee, S.N.,&Kumar, S. ,17,,191-198,Year : 2014)
|
Phytoremediation process using hydrophytes emerges as an attractive scientific and engineering tool for the attenuation of metal pollution in the aquatic environment particularly in secondary and tertiary levels of wastewater treatment. The selection of appropriate plants on the basis of maximum uptake potential for engineering application of the process is the key factor .The present study deals with the use of four numbers of aquatic plants viz. Pistia, Salvinia, Spirodela and Lemna to assess their relative adsorptive efficiencies for chromium (VI) removal from synthetic solution. The plants were hydroponically cultured in Hoagland solution and grown in conjunction with chromium (VI) spiked solution. All the plants exhibited the ability to tolerate and uptake chromium. The kinetic data showed their uptake capacity in the order viz. Pistia > Salvinia > Spirodela > Lemna. For an initial concentration of 2 mg/L, Pistia could effectively sorbed 0.0457 mg of Cr(VI) /g of biomass with 68.5% Cr(VI) removal efficiency as compared to Lemna which could least achieve a minimum uptake of 0.0307 mg/g of biomass with 46% removal after 7 days of exposure

Worldwide distribution of polyclyclicaromatic hydrocarbons in urban road dust.(International Journal of Environmental Science and Technology)
(Majumdar, Deepanjan, Rajaram, B., Meshram, S., Suryawanshi, P., Rao, C. V. C. ,142,,397-420,Year : 2018)

Polycyclic aromatic hydrocarbons (PAHs) is considered as one of the most important groups of organic environmental contaminants due to their toxicity, persistence and ubiquity. PAHs have been monitored in urban road dust at various locations worldwide in about last three decades. Resuspension of road dust containing PAHs is an important route of PAHs exposure to humans. This paper collates the available information on reported concentrations of PAHs in urban road dust at various locations worldwide classified as industrial, residential, traffic, city and commercial and other areas, reported sources of PAHs in urban road dust and related interpretations. Also, available information has been reviewed and documented country-wise. Variation in PAHs concentrations over various worldwide locations have been scrutinized and interestingly, most of the reported average PAHs concentrations were found to be distributed within a very narrow range of values, implying only little variation in average PAH concentrations in spite of great distances between locations, climatic variation and differences in anthropogenic activity.

An innovative approach of urban noise monitoring using cycle in Nagpur, India(Environmental Science and Pollution Research)
(Vijaya Laxmi, Jaydip Dey, Komal Kalawapudi, Ritesh Vijay & Rakesh Kumar ,26,,36812-36819,Year : 2019)

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.

Hydrodynamics and water quality simulation of Thane creek, Mumbai: an impact of sewage discharge
(Ritesh Vijay, Puja Khobragade, R. A. Sohony, Rakesh Kumar and S. R. Wate ,43,,10,Year : 2014)
|
To assess the impact of sewage discharges on creek water quality, a hydrodynamic and water quality simulation was carried out for Thane Creek. DO and BOD values showed non-compliance up to middle and upper stretches during low tide and even in upper stretch during high tide. FC was found beyond compliance level during low and high tides. Simulated results were correlated with observed tide and current as hydrodynamics and DO, BOD and FC as water quality parameters with correlation coefficients 0.66 to 0.91.

Day to day activities of urban population in normal routine conditions are largely affected by the operation of the urban water supply system. In addition, the working hours, pattern of shift duties and living standards in a society decide the quantum of water use at different times in a day. This demand pattern is an important parameter for water supply agencies in order to ensure safe and reliable water supply. In the present study, short term (hourly and daily) water demand is estimated for drinking as well as various other household activities. BIS standards of 135 lpcd and socioeconomic survey data are considered as the basis to derive a time series distribution of water consumption for different activities. Monte Carlo simulation (MCS) is performed to generate the random distribution of consumption pattern. The hourly water consumption for various activities shows persistent behavior with Hurst coefficient in the range of 0.592 to 0.837 and the peak flow factor of the estimated demand pattern is 5. This pattern is useful as a basis for design of service reservoir as well as pump scheduling. It is also an important parameter in the model study in performance assessment of water distribution system (WDS).
