Stubble Burning in North-West India and its Impact on Health
Burning of crop residues released many pollutants, resulting in serious health hazards. This paper is an attempt to explore status of crop residues burning in Northwest India and its consequences on health in general and on child health in particular. An effort has also been made to find out the correlation between stubble burning and increasing incidence of acute respiratory infection (ARI) among children in Punjab. Finally an inventory of suggestions to curb this evil has also been prepared. Based on secondary sources, the data collected from various published studies, reports and NFHS, the present study found that residue burning resulted in the emission of greenhouse and various harmful gases. Such emission of harmful gases is many times higher than the standard level of gases as recommended by Central Pollution Control Board (CPCB). It has also been observed that the phenomenon of stubble burning is quite high in Punjab with comparison to other northwest Indian states resulting into increase in incidence of ARI among children
Phytochemical investigation of seeds of Trachyspermum ammi Linn. by GC-MS
The present study embraces phytochemical investigation of the essential oil extracted from the mature seeds of Trachyspermum ammi Linn for different constituents by subjecting the oil to gas chromatography-mass spectrometry (GC-MS) analysis. The identification of the constituents is based upon retention indices and by comparison of their mass spectral fragmentation patterns against the commercial library mass spectra (Wiley, Nist etc.). Ellagic acid (EA), which is a natural phenol antioxidant, has been isolated from methanol extract from the mature seeds of Trachyspermum ammi Linn. Also, Thymol (Thl), a naturally occurring phenolic compound, has been crystallized by the reported standard procedure from oil extracted from these mature seeds. Both these compounds have been evaluated for their possible anti-cancer effect against a selected panel of human cancer cell lines by means of sulforhodamine B assay
Applied Perspectives of Environmental Psychology and Wellbeing
Environment is a boon given to each and every living organism on the earth. Being with the nature is always a rich source of mental peace and wellbeing. Connectivity with the nature always gives a sense of being blessed by the Almighty God; it leads to enhance the sense of fully functioning self of the individual as well. Environmental Psychology is an interdisciplinary field which focuses on the application of interaction with environment on the mental, physical, social and spiritual wellbeing. Several research studies have indicated that involvement with natural surroundings is beneficial for the enhancement of overall wellbeing of the society in general and of individuals in particular. Nature is significantly important for the mental health as it helps to reduce the level of stress, irritation, anxiety, aggression, cardiovascular disease etc. The need of the hour is to encourage the health promoting lifestyle which ensures the interaction with the environment in the form of morning walks, meditation, mindfulness, yoga, breathing exercises, cycling, skipping, playing outdoor games etc
Synthesis and Characterization of Novel Schiff base Cu(II) Complexes: Antimicrobial and Molecular docking Studies
N2O2 type complexes of C+2uion have been synthesized by the reaction of Salicylaldehyde/ 3,4-diaminobenzophenone/ acetyl acetoneand glutaric anhydride. The ligands and respective metal complexes was established through spectroscopic data (FT-IR, UV-Vis,1H NMR and 13C NMR). They are non-electrolytic in nature as their molar conductivities (ΛM) in DMSO of 10-3 M solution from the EPR study the complexes proposed to be octahedral geometry. All the metal complexes have been screened for their antibacterial activity andthe predicted binding affinity using molecular docking studies
Decolorization of Symmetrical and Unsymmetrical 3-Nitroformazans using Coriolus Versicolor
Natural as well as synthetic dyes are well known and used for dyeing of various materials. Most common use of dyestuffs is in textile industry. Proper decolourisation and disposal of waste water from dyeing industry is an important issue. Symmetrical nitroformazans constitute a special class of azo-hydrazone dyes which have found application in dyeing industry. These dyes are a major cause of water pollution and need to be removed or destroyed before the disposal of waste water from dyestuff industry. Several methods like physical, chemical and biological have been reported for removal of dye in waste water. The commonly used physico- chemical techniques are costly, less efficient and are liable to interference by other waste water constituents. In the present study fungus, Coriolus versicolor was used for decolourisation of 3-nitro-1,5-diarylformazans. Maximum decolourisation of dye was observed after 96 hours incubation and minimum after 24 hour incubation
Retention Behavior of Basic Amino acids on Various Adsorbents layers in DMSO-1MHCl Mobile Phase
The four basic amino acids were chromatographed on various adsorbents layer and also on admixture layers. It is found that in DMSO–1MHCl mobile phases, the adsorbent titanium (iv) tungstate and its admixture with silica gel-G were found more effective than other adsorbent. However, various basics amino acids are separated on these layers. Which have some real life importance
Impact of Sewage on Seed Germination and Growth of Kharif and Rabi Crops
Wastewater is an effective source for irrigation of crop. Sewage generated from a hostel of Thapar University campus, Patiala was used for growing Kharif crops (Lady Finger & Pearl millet) and Rabi crops (Wheat, Fenugreek, Mustard & Cluster bean) for 35 days in plastic cups at laboratory scale. When sewage was applied at 50%, 100% individually, the dilution of 50% supported better growth of crops. Both sewage and soil used showed absence of metal constituents and hence non-possibility of their accumulation in the grown crops. Germination period of crop was observed and it was found different from crop to crop, four days in Lady finger as against eight days in Fenugreek. The biomass was higher in Kharif crops than was in Rabi crops. Composition of soil was estimated and it was found that the nutrients (organic carbon, nitrogen, phosphorus, potassium) had enriched the treated soil besides aiding the growth of crop. The study was found promising suggesting that the sewage could be used as an irrigating medium for crops. However, several growth parameters are to be optimized before sewage is tried for application at commercial scale
Occupational Hazards and their Impact On Workers In Pulp and Paper Industries
The use of numerous synthetic chemicals and other aspects of constructed environment in paper industry have become a matter of concern to the environmentalists. Several studies have revealed that chemical industries are associated with health hazards. However, precious little data is available about the effects of such environment on the health of workers in these industries. Therefore, present study was aimed to investigate the existence of various psychological disorders and physical ailments in workers exposed to hazardous environment in factory premises. The data was collected on a specially designed survey performa from different pulp and paper industries. It was found that the workers were provided with protecting devices but most of them do not use them because of unawareness and climatic discomfort. In order to check the effectiveness of protecting/preventives devises, the workers were divided into two categories : (i) directly exposed (not taking preventive measures) and (ii) indirectly exposed (taking preventive measures) against these conditions vis-à-vis their health (healthy and sick), working conditions (good & poor) and job satisfaction (satisfied and unsatisfied). The extent of correlation amongst health, work environment and job satisfaction has been studied by using Youle’s Coefficient of association and to test the significance of association, Chi-square test of independence of attributes was deployed. The comparison of the two categories was made by using test of proportions. The statistical significance of the differences of the two categories of workers vis-a-vis their physical and mental health was studied by using test of proportions (Z-test). It was found that with the exception of the association between job satisfaction and physical health, which is moderately positive, there is high degree of positive association amongst job satisfaction-mental health and work environment; work environment-physical and mental health
The Contribution of Forest Sector in Building of Green Economy
Protection of environment has been the cornerstone of Indian ethos and culture. Forests play an important role in environmental stability and provide a variety of benefits to the economy. The current environmental crisis presents unique opportunities for moving towards greener future by giving a major thrust to the forest sector that will generate employment, create real and durable assets and help rebuild rural India . The objective of this paper is to assessing the contribution of forest sector in building green economy . The paper is divided into two sections, first section reflects the role of forest sector in building green economy and in second section explains suggestions and policy implications. Use of bio energy will contribute to reduce greenhouse gas emissions and will be helpful in conserving bio diversity as well as will reduce India’s dependence on importing oil. Producing biodiesel from tree-borne oilseeds is seen by many as a win-win opportunity to solve India’s most pressing problems. Biomass is a versatile renewable resource and wood fuels contribute 56 percent of total biomass energy in India. The time seems to be right to give forestry a prime place in India’s pursuit of more equitable, inclusive and sustainable development. Green economy can be built by joint effort of government and people of country. The transition to a green economy will entail moving away from the system that allowed, and at times generated, these crises to a system that proactively addresses and prevents them
