SENSITIVITY ANALYSIS OF A MANGROVE ECOSYSTEM MODEL(Journal of Environmental Systems)
(P. KHANNA
,,,26,Year : 1998)
|
Mangrove ecosystems represent one of the most important ecosystems in terms of commercial use, inasmuch as their productivity is comparable to that of coral reefs and sea grass beds. In the present article, a comparative analysis is presented for delineating the ecological significance of mangrove ecosystems. Then, a mangrove ecosystem computer model is analyzed, and sensitivity analyses identify key parameters in the design of environmental management plans aimed at optimal and judicious use of mangroves. Analytical expressions are derived for steady state conditions. Moreover, conditions for ecological feasibility are also ascertained. Tidal action and nutrient inputs from terrestrial run-off turn out to be one of the most important controlling factors with respect to detritus export and nutrient cycling.

An insight into phage diversity at environmental habitats using comparative metagenomics approach(Current Microbiology)
(Krupa M. Parmar, Rajesh R. Pal, Nishant A. Dafale, Hemant J. Purohit,75,,32-141 ,Year : 2018)

Bacteriophages play significant role in driving microbial diversity; however, little is known about the diversity of phages in different ecosystems. A dynamic predator–prey mechanism called ‘‘kill the winner’’ suggests the elimination of most active bacterial populations through phages. Thus, interaction between phage and host has an effect on the composition of microbial communities in ecosystems. In this study, secondary phage metagenome data from aquatic habitats: wastewater treatment plant (WWTP), fresh, marine, and hot water spring habitat were analyzed using MG-RAST and STAMP tools to explore the diversity of the viruses. Differential relative abundance of phage families—Siphoviridae (34%) and Myoviridae (26%) in WWTP, Myoviridae (30%) and Podoviridae (23%) in fresh water, and Myoviridae (41%) and Podoviridae (8%) in marine—was found to be a discriminating factor among four habitats while Rudiviridae (9%), Globuloviridae (8%), and Lipothrixviridae (1%) were exclusively observed in hot water spring. Subsequently, at genera level, Bpp-1-like virus, Chlorovirus, and T4-like virus were found abundant in WWTP, fresh, and marine habitat, respectively. PCA analysis revealed completely disparate composition of phage in hot water spring from other three ecosystems. Similar analysis of relative abundance of functional features corroborated observations from taxa analysis. Functional features corresponding to phage packaging machinery, replication, integration and excision, and gene transfer discriminated among four habitats. The comparative metagenomics approach exhibited genetically distinct phage communities among four habitats. Results revealed that selective distribution of phage communities would help in understanding the role of phages in food chains, nutrient cycling, and microbial ecology. Study of specific phages would also help in controlling environmental pathogens including MDR bacterial populations using phage therapy approach by selective mining and isolation of phages against specific pathogens persisting in a given environment.

"This paper reviews how active research inWest Bengal has unmasked the endemic arsenismthat has detrimental effects on the health of millions of people and their offspring. It documents howthe pathways of exposure to this toxin/poison have been greatly expanded through intensive application of groundwater in agriculture in the regionwithin the Green Revolution framework. A goal of this paper is to compare and contrast the similarities and differences in arsenic occurrence in West Bengal with those of other parts of the world and assess the unique socio-cultural factors that determine the risks of exposure to arsenic in local groundwater. Successful intervention options are also critically reviewedwithemphasis on integrative strategies that ensure safewater to the population, proper nutrition, and effective ways to reduce the transfer of arsenic from soil to crops. While no universal model may be suited for the vast areas of the world affected with by natural contamination of groundwater with arsenic, we have emphasized community-specific sustainable options that can be adapted. Disseminating scientifically correct information among the population coupled with increased community level participation and education are recognized as necessary adjuncts for an engineering intervention to be successful and sustainable."

(Manda Karunakar Reddy, Mareddy Sumathi,662-667,,662-667,Year : 2011)
|
The aerodynamic diameter of an air borne particle is the key property in determining its respiratory deposition. The study aim to assess PM2.5 level and its size distribution at 5 traffic junctions located along the lateral highway connected to NH-202. A cascade impactor has been used to measure the size function range of PM2.5 apart from PM10 of atmospheric dust particles in air being PM2.5 is concern with respect to effect on human health and is able to tend deeply into the respiratory tract reaching the lungs. It is observed that weight % of PM2.5 values are in the range of 40% - 60% of PM10 and few values of PM2.5 are exceeding the standards prescribed by CPCB. It is concluded that free flow of traffic is main concern and maintenance of road should be carried out during low traffic hours.

In India, festivals are celebrated with lot of enthusiasm and Diwali is the major festival of light. In this festival, houses are illuminated by lights and sky is illuminated by fireworks. These fireworks though create lot of amusement but also pollute the atmosphere in terms of air pollution. The continuous air pollution monitoring was undertaken during Diwali festival (2014) at residential site NEERI, Nagpur. Air quality parameters were compared with CPCB standard. On Diwali day, PM 10 and PM 2.5 concentration achieve its highest value of 900 µg/m 3 and 950 respectively µg/m 3. This high concentration is maintained in atmosphere for two days of this festival in atmosphere which is approximately 8-9 times more than that regulatory standard. These particles carry all the components of the cracker including heavy metals, alkali metals, alkaline earth and change the atmosphere with positive and negative ions apart from impaction of sulfur and other acid gases to the atmosphere.

Equilibrium modeling for biosorption of safranin onto chemically modified biomass of marine Aspergillus wentii(Water, Air, and Soil Pollution)
(Yasmin Khambhaty, Kalpana Mody and Bhavanath Jha, 679-691,,,Year : 2011)
|
Safranin was used as a model reactive dye for biosorption studies onto various forms of chemically modified biomass of Aspergillus wentii. The experimental equilibrium data was analyzed by various single-, two-, three-, four-, and five-parameter isotherms to understand the biosorption process. Biosorption isotherms modeling shows that the interaction of safranin with A. wentii surface is localized monolayer sorption. Results show that in general the accuracy of models to fit experimental data improves with the degree of freedom. The interaction among adsorbed molecules is repulsive having no association between them and sorption is carried out on energetically different sites and is an endothermic process. The five-parameter Fritz–Schluender model gives the most accurate fit with high regression coefficients (0.9902–0.9941), low standard errors (0.0389–0.0758), and sum of squares error (0.0075–0.0230) values to all experimental data in comparison to other models. The results disclose that the sorption isotherm models fitted the experimental data in the order: Fritz–Schluender (five-parameter) > Langmuir > Khan > Fritz–Schluender (four-parameter) > Temkin. This systematic evaluation of the more important equilibrium isotherm models provided the general basis for making a preliminary selection of an effective model for a given application.

Membrane filtration immobilization techniquea simple and novel method for primary isolation and enrichment of bacteriophages(Journal of applied microbiology)
(Ghugare, G. S., Nair, A., Nimkande, V., Sarode, P., Rangari, P.
,Vol.122 ,Issue 2,531-539,Year : 2016)

Aim:
To develop a method for the isolation and enrichment of bacteriophages selectively against speciÞc bacteria coupled with a membrane Þltration technique. Methods and Results: Rapid isolation and concentration of host-speciÞc bacteriophages was achieved by exposure of the sample suspected to contain bacteriophages to a speciÞc host immobilized on a 0 45 lm membrane in a membrane Þltration unit. The principle behind this method is the exploitation of host-speciÞc interaction of bacteriophages with their host and maximizing this interaction using a classic membrane Þltration method. This provides a chance for each bacteriophage in the sample to interact with the speciÞc host on the membrane Þlter Þtted with a vacuum pump. SpeciÞc bacteriophages of the host are retained on the membrane along with its host cells due to the effect of adsorption and these adsorbed bacteriophages (along with their hosts) on the Þlter disc are then ampliÞed and enriched in regular nutritive broth tryptose soya broth by incubation. With the help of the plaque assay method, host-speciÞc phages of various bacterial species were isolated, segregated and enriched.
Conclusions:
The phage concentration method coupled with membrane Þltration immobilization of host bacteria was able to isolate and enrich the host-speciÞc bacteriophages by several fold using a lower quantity of an environmental water sample, or other phage suspensions. Enrichment of phages from single plaques was also achieved. Significance and Impact of the Study: The isolation and detection of host-speciÞc bacteriophages from a low density bacteriophage water sample in a single step by the use of a simple and basic microbiological technique can be achieved. Enrichment of phages from low phage titre suspensions is also achieved very effectively.

A roadmap for development of sustainable e-waste management system in India(Journal of Science of the Total Environment)
(P. S. Dutt,409,1, 1 ,19-32,Year : 2010)
|
The problem of E-waste has forced Environmental agencies of many countries to innovate, develop and adopt environmentally sound options and strategies for E-waste management, with a view to mitigate and control the ever growing threat of E-waste to the environment and human health. E-waste management is given the top priority in many developed countries, but in rapid developing countries like India, it is difficult to completely adopt or replicate the E-waste management system in developed countries due to 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. This paper presents a review and assessment of the E-waste management system of developed as well as developing countries with a special emphasis on Switzerland, which is the first country in the world to have established and implemented a formal E-waste management system and has recycled 11 kg/capita of WEEE against the target of 4 kg/capita set by EU. And based on the discussions of various approaches, laws, legislations, practices of different countries, a road map for the development of sustainable and effective E-waste management system in India for ensuring environment, as well as, occupational safety and health, is proposed.
