ABSTRACT

The main issues with solid waste management today are to identify and select the most appropriate solid waste treatment technologies as well as disposal method in selected areas. However the decision making process is getting more complicated especially dealing with its cost efficiency. Thus, the Analytical Hierarchy Process (AHP) was chosen to use as tools to facilitate the decision making task. It is a method developed to support multi-criteria decisions, effective and practical approach that consider complex and unstructured decision. One model was developed as General Hierarchy Structure Model (GHSM) for selecting an appropriate solid waste treatment technology. The models was structured into hierarchy consists of goal, criteria subcriteria and alternatives. Based on political support, technical expertise, environmental impact, market potential, community involvement and cost critera, GHSM will give priority to recycling, composting, incineration or combination of technologies. The case study in Sepang Municipal Council, have shown that the combination of recycling and composting technology is the best alternative and suitable in Sepang area.

ABSTRACT

Sediment samples from the coast of River Orogodo in Agbor, Delta State, Nigeria were sampled over four months (May to August) and analysed for heavy metals ( Cd, Mn, Fe, Cu, Ni, Pb, Zn, Cr) using Atomic absorption spectroscopic method. Some specific physico-chemical characteristics, such as organic matter, pH and conductivity which are known to influence the interactions and dynamics of metals within the sediment matrix were also determined. The result of the analysis indicates significant difference (p<0.05) in pH, organic matters, Mn, Zn and Cr levels for the four month variation. The concentration ranges of metals (in mg/kg of dry sediment) measured were in order of Fe (339-925) > Mn (4.02 -0.50) > Zn (1.91 -1.11) > Cu (1.04-0.10) > Pb (0.96-0.30) > Ni (0.75-0.57) >Cd (0.43-0.09) > Cr(0.30-0.10). The significant correlation (p<0.05) however exists between some of the metals and some also show high correlations at p<0.01.The concentrations of most heavy metals are low, but iron content is higher than the background value and DPR standard for soil/sediment which indicates significant contamination by iron in the water body.

Keywords : Sediment, Contamination, Heavy metals and Pollution.

ABSTRACT

Consumption of foods and vegetables contaminated with heavy metals is a major cause of disease and debility. In this study carried out in 15 non-oil prospecting selected towns in Delta State, Nigeria covering the three (3) senatorial districts of the state, and five (5) towns from each of the senatorial districts, the lead content of Telfairia occidentalis was determined.The mean lead concentration of the locations were tabulated with P< 0.05 student t-test and F-distribution ANOVA at P< 0.05 and P< 0.01 and these showed a significant difference among the three (3) senatorial districts. The mean concentration of lead in each district are 4.660mg/kg for Delta South, 5.771mg/kg for Delta North and 4.305mg/kg for Delta central with none exceeding the approved standard limit of 100mg/kg of the World Health Organisation. It can therefore be hypothesized that Telfairia occidentalis cropped within Delta State, Nigeria, in non-oil prospecting locations is safe for human consumption with regard to lead levels.

Keywords : Telfairia occidentalis, lead concentration, non-oil prospecting locations.

ABSTRACT

Formaldehyde is extensively used for disinfection and antisepsis in medical facilities and especially in textile and paint industries as a solvent. Owing to the higher concentration of formaldehyde, both in waste effluents and local environment of medical facilities and industries, it has been reported to cause cancer and as an irritant to eyes and skin. The removal efficiency and the adsorption mechanism of formaldehyde onto the treated activated carbons and activated alumina were studied to analyze the effect of modified surface chemistry of adsorbents. The adsorption capacities of all the selected adsorbents were investigated in batch study at varying contact time and initial concentration of formaldehyde at STP. It was found that commercially implemented activated alumina, treated with effective nucleophile, showed significant formaldehyde adsorption with less variation in adsorption capacity even with decrease in initial concentration of adsorbate. These set of experiments indicate that acidity of formaldehyde can be exploited for its removal from waste effluent and air. The optimization studies were carried out to find out the optimum conditions for this adsorption process with adsorption model fitting and kinetic studies. The investigation results were evaluated on per gram of adsorbent basis to predict feasibility of scaling up at commercial level.

ABSTRACT

Energy is the prime mover of economic growth and it is a wheel of modern economy. Future economic growth crucially depends on the long-term availability of energy, and cost of sources, availability, accessibility, and environmental friendly. India is a developing country and it needs more energy to accelerate the rate of development. India has the sixth position in the total energy consumption in the world. The energy resource is constant but energy consumption increases day by day. So each country requires more energy efficient equipment for the development and to save energy consumption. There are three ways for efficient energy conversion (a) Discover new energy resource (b) To minimize the energy losses (c) waste heat recovery. Here every human needs the energy for cook food. In India 74% population of India lives in villages and uses the conventional resources e.g. wood, cow dung and agriculture waste and available of bio-mass. So, I select rural area where mostly use bio-mass fuel, like wood and agriculture waste. The chulha (wood stove) use as a cook furnace for bio-mass in rural area. The traditional chulha give low thermal efficiency. In view of conservation of wood fuel and reduction of smoke from the kitchens of rural. In view of conservation of wood fuel and reduction of smoke from the kitchens of rural India, the Ministry of Non-conventional Energy Sources(MNES), Government of India, launched a National Programme on Improved Chullhas(NPIC) during 1984- 85. The NPIC measure traditional Chullhas have thermal efficiency is 8 to 10 percent but in my modified model, thermal efficiency has improved by 15 to 17 percent through extra supply of air. The thermal efficiency of modified chulha over the conventional chulha is 7 % to 9% more. In my modified model do not create pollution into environment due to complete combustion of fuel.

ABSTRACT

Air is the most important factor of environment. Without air no body can survive. But today the polluted or degraded air quality is a big problem because pollution of air has affected the health of people or causing many diseases. Air pollution raises Blood Pressure according to the study of Sherry Baker¹. Pollution problem cannot deal only technology. Hon’ble Justice Niley Chowdhary said that enormous pollution control problem can be dealt with isolation. It should be integrated with total over all national planning schemes as also with the vibration of Judicial process² and Justice Krishana Iyer has pointed out that if development programs are extensive and extraordinary as they are bound to be, are delinked from the legal process, the decline and fall of democracy may certainly begin³. It means that without economists, sociologists, scientists and lawyers, the pollution can not be solved. Law is regulator of human conduct. There are about 200 major laws directly related to environmental protection. The number of minor legislation directly or indirectly related to control pollution is closed to 3000. M.P. Government also has formed and passed various Acts and Rules to control pollution. Air (Prevention and Control of Pollution) Rule 1983 is direct force to control of air pollution of the state but some other Acts and Rules of M.P., are also participated to control the air pollution. We must be aware of these Acts and Rules because we control the pollution origin place or complaint to proper authority for necessary action.

ABSTRACT

Out of various no edible oil resources, jatropha curcas oil is considered as a promising alternate fuel for CI engines. The present study describes the process used for production of degummed jatropha oil (DGJO) and jatropha methyl ester (JBD) The important fuel properties of DGJO and JBD were determined and compared with fossil diesel and jatropha oil. The degumming and trans esterification process has reduced the viscosity by 19.8% and 74.8% respectively. The heating of degummed oil at 70 0C reduce the viscosity by 6.8 times when compared with viscosity at 10 0C. Further the degummed oil at 70 0C becomes viscous at par with fossil diesel, hence could be used directly in IC engines.

ABSTRACT

We discuss the formation of new products in a solid – solid reaction in the capillary as in well as in bulk in the presence of an organic solvent impurity in a small amount. Three reactions namely KI + HgCl2, CuI + HgCl2 and AgI + HgCl2 were studied. It was found for some of the organic solvent impurities, a small amount of some substance appeared in the half occupied by HgCl2. Thus it became clear that some of the organic substances were reacting with HgCl2 to produce a new substance which be an organo-metallic product. In this light HgCl2 was made to react with the different solvents. However, the new product could be separated out only in two cases, with Cyclohexanone and Dimethylsulfoxide. A black coloured product was formed with Cyclohexanone and with Dimethylsulfoxide the new product was of a light greenish colour. With the other solvents like Acetophenone and Nitrobenzene, the product, if formed, could not be separated out. So a preliminary study of the two products naming these as product A and product B formed with Cyclohexanone and Dimethylsulfoxide respectively has been done. The product A is formed by the reaction of Cyclohexanone solvent with HgCl2 and product B is formed by the reaction of Dimethylsulfoxide solvent with HgCl2 both at 80ºC, for 5 hours. The preliminary studies carried out were measurement of molecular weight (by elevation of boiling point method), ionicity, XRD, FTIR etc.

ABSTRACT

If any substance is interesting, it’s hydrogen peroxide. By now everyone’s aware of the ozone layer that surrounds the earth. Ozone consists of three atoms of oxygen (03). This protective layer of ozone is created when ultraviolet light from the sun splits an atmospheric oxygen molecule (02) into two single, unstable oxygen atoms. These single molecules combine with others to form ozone (03). Ozone isn’t very stable. In fact, it will quickly give up that extra atom of oxygen to falling rainwater to form hydrogen peroxide (H202). It is this hydrogen peroxide in rainwater that makes it so much more effective than tap water when given to plants. With the increased levels of atmospheric pollution, however, greater amounts of H202 react with air-borne toxins and never reach the ground. To compensate for this, many farmers have been increasing crop yields by spraying them with diluted hydrogen peroxide. We can achieve the same beneficial effect with house plants. If you’ve never used Hydrogen Peroxide you are overlooking one of the most powerful healing tools ever discovered. Most of us started on hydrogen peroxide shortly after birth. Not only does mother’s milk contain high amounts of H202, the amount contained in the first milk (colostrum) is even higher. This seems only reasonable now that we know one of its main functions is to activate and stimulate the immune system. Hydrogen peroxide is safe, readily available and dirt cheap. And best of all, it works! We do know that it is loaded with oxygen. (Half a liter of the food-grade 35% solution contains the equivalent of 65 lits of oxygen under normal conditions. We also know that when H202 is taken into the body (orally or intravenously) the oxygen content of the blood and body tissues increases dramatically. Hydrogen Peroxide is most versatile chemical used in various industries as bleaching agent, reagent in chemical synthesis, environmental control / effluent treatment, sterilization etc. The important constituent being active oxygen which is obtained by the controlled decomposition of H2O2 and water as a by-product. In this paper, the usage of H2O2 to provide ‘clean’ processes, without the production of any harmful or environmentally unsafe product is presented.

ABSTRACT

A preliminary report of some of the results of the measurements of the electrical conductivity of HgCl2, HgBr2, HgI2 and an equi-molar mixture of HgCl2 and HgBr2 and another of HgBr2 and HgI2, all these being pressed to 10 tons/cm2 of pressure, are reported. The very low value of the electrical conductivity of the two equimolar mixtures, compared to those of the corresponding double halides strongly suggests formation of some new product in both the cases. This is also supported by the X- ray diffractograms of the compounds. Finding the nature of the product is a matter for detailed study before any reliable conclusions can be drawn.

ABSTRACT

A physico-chemical study of the Kerwa dam, Kolar dam and Kaliasote dam of Bhopal has been carried out to examine the suitability of surface water for drinking purposes. Water Samples were collected from two sampling stations of each dam and analyzed (APHA, AWWA, WEF, 1998) for the physico–chemical parameters such as temperature, pH, electrical conductivity, total hardness, calcium hardness, magnesium hardness, sulphate, fluoride and chemical oxygen demand (COD) to know the present status of the water bodies. The concentrations of investigated parameters in the water samples were within the permissible limits of the World Health Organization drinking water quality guidelines except for the values of COD and total hardness. The value of COD was found in the range of 18 mg/l to 30 mg/l which was much higher than the maximum permissible limits as prescribed by WHO standards (1993). The value of total hardness ranges from 118 mg/l to 170 mg/l which is also above the permissible limit as prescribed by WHO standards.

ABSTRACT

The use of chemical fertilizers in the catchment area of the Kaliashote reservoir has increased many fold thus, residual impact of the chemical fertilizer as well as agriculture waste inflow in the lake considerably increased water pollution problem. The residues of the chemical fertilizer reaching to the Kaliashote reservoir with storm water enriched the lake water with the loading of nutrients. The extra loading of the nutrient causes eutrophication that supports luxuriant growth of macrophytes. Results of analyzed of several physicochemical parameters such as pH, Conductivity, Dissolved Oxygen(DO) , Biological Oxygen demand(BOD) , Chemical Oxygen demand(COD), Nitrates ,Phosphates and Potassium shows high concentration of nutrients in the areas where chemical fertilizer are being used (at the station near Bhadbhada) in comparison Reference sample i.e. Behind MACT, Kaliasote Reservoir.

ABSTRACT

Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications. Encompassing nanoscale science, engineering and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale. At this level, the physical, chemical, and biological properties of materials differ in fundamental and valuable ways from the properties of individual atoms and molecules or bulk matter. Nanotechnology R&D is directed towards understanding and creating improved materials, devices, and systems that exploit these new properties. It is expected to result in cleaner and less wasteful methods of manufacture, stronger and lighter building materials, smaller yet faster computers, and more powerful ways to detect and treat disease. Nanotechnology promises exciting break through and sustainable future. This paper fundamentally covers how nanotechnology can be envisaged as a green alternative in different aspects nanoparticle synthesis – by green route Use of metal nanoparticles and nano clay as additives in polymer nanocomposites - special applications with respect to composites in packaging Minimizing the use of non-biodegradable plastics (thermoplastic & thermosetting) and replacing them to some extent with biodegradable plastics and biopolymers Tailor made applications and future needs

ABSTRACT

Presently, traditional educational approaches have resulted in a mismatch between what is taught to the students and what the industry needs. As such, many institutions are moving towards problem-based learning as a solution to producing graduates who are creative, can think critically and analytically, and are able to solve problems. In this paper, we focus on using multimedia technology as an innovative teaching and learning strategy in a problem-based learning environment by giving the students a multimedia project to train them in this skill set. The purpose of this project was to access the students’ skills in framing and solving problems using multimedia technologies. The students worked in groups and each group had to pick a topic for their project, develop, design and present it in a CD-ROM. They were then surveyed on their attitudes toward the project and their skills as a team. Results showed that the students were very positive toward the project, enjoyed teamwork, able to think critically and became active participants in their learning process. Therefore, multimedia-oriented projects, like many other problem-based learning solutions, can be used alternatively as an innovative and effective tool in a problem-based learning environment for the acquisition of problem-solving skills.

ABSTRACT

Ground water samples of the selected locations in Dhule city were analyzed in respect of physico-chemical aspects in order to determine the potability of the water and call for same effective measures to be taken to minimize the adverse impact on human health. The avarage values of assessment were compared with the standards given by WHO, ISI and ICMR. It was found from present study that there are variations in many physico-chemical parameters. The sample S-1 and S-3 were found within the possible limits, while S-2 and S-4 shows large variations and found to be exceeding their acceptable limits of standards indicating poor potability due to contamination from sewage.

ABSTRACT

Ground water quality and its impact on human health in and around Mangalam, near Tirupathi, India was assessed. Water samples were collected from 8 different areas in and around Mangalam and analyzed for physicochemical parameters such as pH, electrical conductivity, total dissolved solids, total hardness, calcium, chlorides, sulphates, nitrates and dissolved oxygen. The found values of physicochemical parameters were compared with the World Health Organisation water quality standards. Based on the analysis, it was found that ground water of some of the areas was polluted and not suitable for drinking purpose. Thus the ground water of the area needs purification before drinking.

Keywords : Ground water, physicochemical parameters, purification, permissible limit.
