Indian J Tradl Knowledge 2016, 15(1), 22-9.
This research explored the relationship between vulnerability and the use of indigenous knowledge in mitigating disasters particularly those linked to food security and preservation of forest resources in some communities in Zimbabwe. This focus on provision of food was important since food issues have an immediate impact on communities and for vulnerable communities forest resources are also linked to food security. Data was collected through both formal and informal interviews, and group discussions with the elderly and traditional leaders in Matebeleland and Mashonaland provinces of Zimbabwe, hence a qualitative research approach was used. Although the findings are unique to the communities involved, it is important to note that vulnerable communities do possess a wide range of indigenous measures to mitigate disaster risk. Firstly, it is the realisation that technology does not necessarily refer to modern or objective science, but solutions that lead to sustainable livelihoods for local communities, which include environmentally based early warning signs which allow them to take precautions before a disaster like drought, flood, pests, etc., occurs as well as measures to reduce the impact of such a disaster. Secondly, production, harvesting and conservation have always been inbuilt in the farming techniques of these rural communities and mushrooms that form a regular part of the diet and provide protein for rural communities are a good example. Since time immemorial they have always been preserved within their natural habitats and women who have always been able to distinguish edible mushrooms from toxic ones have always known how to stimulate their growth by applying crop waste or ash as fertilizers to the ground on which they grow. Lastly it is natural for some indigenous techniques to lie dormant as if they are extinct. This is because every generation makes its own contribution to improvise and adapt the knowledge system in line with the ever changing climatic conditions. The article recommends that since the proportion of non-sustainable practices in traditional knowledge systems is much smaller than the benefits accrued through its use in the contemporary modern life and belief systems, there should be development, use and adaption of technologies that have links with indigenous knowledge systems. Developing contextually relevant educational processes that identify and build upon local knowledge and expertise for disaster risk reduction is needed and where possible, expressed in local language and context. In short vulnerable villagers should have more legitimate authority over natural resources for they are more responsive than local government authorities.

J Indian Geophys Union 2016, 20(6), 575-85.
In the present study, microwave radiometer observations were used to understand the thermodynamic state of the atmosphere before, during and after the thunderstorm events occurred over two contrasting environments i.e. Pune and Mahabaleshwar. Initially thermodynamic state of atmosphere was analyzed using single cases from each site. Analysis of temporal variability of atmospheric parameters and associated thermodynamic indices of individual events showed significant positive differences between Pune and Mahabaleshwar in surface fields like temperature before thunderstorm, while surface relative humidity (RH) records indicated negative differences. Differences in various thermodynamic indices showed that strength of instability is higher over Pune compared to that over Mahabaleshwar. Later composite analysis along with difference of the mean was verified so as to confirm the results quantitatively. Among the represented thermodynamic indices lifted index, humidity index and show-alter index showed a negative difference, whereas total index, k-index and convective temperature showed positive difference before and during the storm. However, no significant changes were observed after the thunderstorm activity. Analysis suggested that there is a regional difference in thermodynamic features during the evolution of thunderstorm and also a possibility of thunderstorm potential over Pune compared to Mahabaleshwar. This work also shows the robustness of ground based microwave radiometry for the study of convective events.

J Envir Biosci 2015, 29(1), 17-21.
In present scenario excessive siltation leading to drastic deduction in water storage capacity is a stumbling block for reservoirs. Reduction in water spread area at a specified elevation over a period is indication of sediment deposition in the reservoir. Reduction in the storage capacity of a reservoir hinders the purpose for which it was proposed. Thus assessment of sedimentation becomes very indispensible aspect for the management and proper operation of the reservoirs. For this purpose, an observation was proceeded to fathom the sedimentation of Nanak Sagar reservoir, located on the Deoha River in the Tarai region of Uttarakhand using multi-dated Remote Sensing (RS) images. IRS LISS III remote sensing data for the year 2007 and original capacity curve were optimized in the study of the capacity loss to various water levels. The morphology of the reservoir has been changed significantly due to sedimentation during the period 1962 to 2007. The reservoir has lost a total of 56.19 Million Cubic Meter (Mm3) by dint of sedimentation which is accounted as 26.78% of the total capacity during last 45 years and average deposition was computed as 1.25 Mm3 (0.59%) per year. It's concluded that the maximum siltation deposited on upper region of the reservoir on the basis of huge difference between original cumulative water volumes and derived cumulative water volume at corresponding elevation of the reservoir.

The Bangalore Metropolitan Transport Corporation (BMTC) took an initiative to check the overall benefits of introducing electric buses as a suitable replacement for the diesel buses to tackle the burgeoning pollution in the city of Bengaluru, India. For a trial run of three months, an electric bus was procured from a Chinese company 'Build Your Dreams' (BYD). Data were collected by BMTC on the operation and maintenance of the bus. This new initiative, if rightly guided, could have a direct impact on the lives of those in the city. An economic analysis of the running as well as maintenance of the electric buses within the city limits was performed. For comparison, the same analysis was performed for the data from the existing diesel bus operating on the same route. On the basis of the study, it can be concluded that the introduction of electric buses as a means of public transport in the city would be beneficial both economically as well as environmentally. The electric bus also makes much less noise, thereby helping reduce noise pollution and makes less vibration when compared to the diesel bus. This results in a more comfortable journey for the passengers.

Simultaneous determination of elements in groundwater (ng L-1 to g L-1) in single analysis by DRC ICP-MS was developed. The technique of extended dynamic range based on DRC could be able to detune the signal response of selective elements to enable incorporation of high concentration elements (outside of the ion detector' dynamic range to 1e9 cps) into a single analysis without affecting signal response of other trace elements. The signal sensitivity of high concentration element (i.e., K, Na, Ca, Mg and Fe) was suppressed easily by adjusting the voltage parameters of DRC quadrupole (RPa) and the groundwater samples could be online diluted any multiples (i.e., from one time to million times) according to the actual need. In order to eliminate mass spectral interferences (i.e., 40Ar35Cl+, 40Ar40Ar+, 12C40Ar+, 44Ca16O+, 23Na40Ar+, 25Mg38Ar+ and 26Mg40Ar+), the operational conditions of the DRC, working with CH4 as reaction gas, were optimized for 75As, 80Se, 52Cr, 60Ni, 63Cu and 66Zn. The analytical results of a reference material CASS-5 were in good agreement with the certified values. Reliability of the data was also tested by comparing the results for 29 groundwater samples with those determined by ICP-OES and good agreement was obtained for the high concentration elements. As the routine method in our laboratory, the satisfactory results indicate that it has great potential for the determination of low and high concentration level elements by one single analysis in various samples.

Today, humans and wildlife are constantly exposed to thousands of chemical residues, through air, food and water. Organochlorines are widespread pollutants and comprise a variety of compounds containing carbon, hydrogen, and chlorine. Chlorinated insecticides, solvents, and fumigants are widely used around the world. Exposure to organochlorine chemicals has been associated with many deleterious effects on human health. Concerns have been raised about their implication in reproductive toxicity and endocrine disruption, because organochlorine chemicals persist in the environment. Organochlorines interfere with normal hormonal function in animals and humans. Reproductive abnormalities, including feminization of males, abnormal sexual behavior, birth defects, altered sex ratios, decreased sperm production, reduced testicular size, infertility, and thyroid dysfunction, have been reported in laboratory animals and wildlife exposed to endocrine-disrupting chemicals. This review deals with adverse effects of different organochlorine chemicals on male reproductive system, thus indicates limited use of organochlorines to improve the quality of life for human welfare.

Asian J Chem 2015, 27(9), 3420-30.
In this study, different agricultural waste materials, namely rice husk, sugarcane bagasse, mustard oil cake, tea waste, betel nut peel and saw dust, were investigated for their potential to remove Cr(III) and Cr(VI) from aqueous solutions. The effect of solution pH, contact time, biosorbent dosage and initial Cr(III)/Cr(VI) concentration on its biosorption was first studied under batch condition. Among the six biosorbents tested in this study, sugarcane bagasse removed Cr(III) with a maximum efficiency of 89.14%, whereas rice husk yielded a maximum Cr(VI) removal efficiency of 79.48% under the batch condition. Chromium sorption kinetics was best explained by the intra particle diffusion based second order kinetics model. Fourier transform infrared, scanning electron microscope analyses of sugarcane bagasse and rice husk were performed before and after its chromium loading in order to analyze the morphology and the functional groups responsible for the chromium biosorption. Continuous column sorption of Cr(III) and Cr(VI) were carried out in two identical fixed-bed columns with sugarcane bagasse and rice husk, respectively, as the biosorbents. The influence of bed depth and flow rate on continuous chromium sorption was investigated at 30 mg L-1 inlet concentration. The chromium breakthrough and saturation time in both the columns increased with a decrease in the flow rate from 30 to 10 mL min-1. The same effect was observed with an increase in the column bed depth from 10 to 30 cm.

The rapid development in the industrial sector leading to the drastic changes in the environmental equilibrium and is the prime challenge to scientists as the natural resources are very precious. The sugar industrial effluent mainly shows an adverse effect on the water quality parameters like D.O., B.O.D., C.O.D., pH, temperature and conductivity of the surrounding aqua systems at the time of discharge. The abnormal levels of these parameters cause pollution in water bodies and even death of aqua flora and fauna. However, sugar industrial effluents are found hazardous and they enter the environment through various channels of waste water discharges. Conventional treatment technologies for the removal of industrial effluents are less economical than that of biological methods. Phytoremediation techniques have been found potential to absorb effluents to maximum extent and without possibility of secondary pollution. The prime objective of this paper is to investigate the capability of selected aquatic plant species of Eichhornia crassipes, Pistia stratiotes, Nelumbo lutea and Marsilea quadrifolia for the removal of sugar industry effluent toxicity from the contaminated aqueous environment. The changes in the water quality parameters during the treatment of industrial effluent with aquatic plants were verified periodically to optimize the process.

Int J Fish aqua Stud 2016, 4(5), 41-6.
The aim of this study is to measure the levels of Cu, As, Zn, Ni and Hg found in muscle of three common fish species collected from the coast of Black Sea, Bulgaria and to determine their potential effects via calculation of the daily intake of metals and estimated weekly intake of metals. To estimate the human health risk, the target hazard quotients (THQ), was calculated. THQs for individual metals were lower than the guideline value of 1. Hazard Index of each trace element were lower than one suggesting that these pollutants perhaps pose no hazard to local residents. Target risk due to As (3.63x10-5 - 5.47 x10-5) and Ni (2.65x10-7 - 5.07 x10-7) exposure through fish consumption may not have the probability of contracting cancer over a long lifetime in future. More intensive studies are necessary in order to determine the toxic metals in fishes from this area of Black Sea.

Sponge iron solid waste dumps represent a distressed habitat and posses scare in the natural landscape of the area and such dumping sites therefore need urgent attention for their reclamation. Physico-chemical properties of 0, 1, 3 and 5 yrs old sponge iron solid waste dumps were analyzed. A comparative analysis of physical features of different age series sponge iron solid waste dumps revealed an improvement of textual (increase in clay and slit) and structural (decline in bulk density) properties along with the improvement in hydrological regime (water holding capacity and moisture content). pH of the different age series sponge iron solid waste dumps gradually shifted from alkaline range to the neutral range. The soil organic carbon, nitrogen and extractable phosphorous in the freshly laid dump was observed to be beyond the detection limit. However, with the increase in the age of the waste dumps, the carbon, nitrogen and phosphorous content showed progressive increase. C: N ratio was showing declining trend with increasing age of the waste dumps. Findings of the present study indicated the positive effect of soil supplementation and natural vegetation succession on the process of reclamation of the waste dump converting it into a natural ecosystem.

Cement is the basic material for buildings and civil engineering constructions. Portland cement, the most widely used cement in concrete construction, was patented in 1824. Cement is a fine powdery material untwining silicates of calcium, formed out of raw materials consisting calcium oxide, silica, aluminum oxide and iron oxide. India has an installed capacity of 234 million tons per year, making this is the second highest Cement producer in the whole world. As is the case in the United States, several multinational Cement producers have built up a larger share of India's Cement production industry. Among many countries India is the second highest producer of cement in the world, with 130 large cement plants and an installed capacity of 234 million ton per annum (94% of which is from large cement plants). During 2006-2007 cement production grew at a rate of 9.1% compared to the same period the previous year. However, despite this growth, India's per capita production is 115 kg per annum, well under the world average of 250 kg (World Cement 2007). The Cement manufacturing sector plays a vital role in the nation's economic development since cement is the most versatile and widely used construction material. The cement industry has made phenomenal progress in terms of volume, technology and product up gradation in recent years.

In this study, the impact of traffic activities on K, Cr, Ir and Pd heavy metals ion concentration of roadside soil of Madinah city, Saudi Arabia. Surface and 20 cm under surface soil samples from 12 different sites were collected and analyzed. The measured concentration of the four heavy metal ions was correlated to the traffic density which was monitored in roads near the sampling sites. In addition, a comparison was made between the concentration and those of Zn and Pb investigated previously. The results revealed significant dependence of Cr and Ir on traffic density with correlation coefficients of 0.948 and 0.898, respectively. The other two metals, K and Pd showed no dependence on traffic density and no dependence between the surface and under surface concentration. The values of pollution indices such as contamination factor, degree of contamination and geo-accumulation index indicated various levels of contamination in the roadside soil. The degree of contamination values in the most five polluted sites were 258.718, 180.854, 142.737, 88.477 and 79.153, corresponding to the airport road (1), Taibah University street (2), Orwah Valley street (3), Qubaa Municipality (4), East Al-Haram area (5), respectively.

The study was conducted in fields using two different types of irrigation water namely, recycled (RCL) and non-recycled (N-RCL) water. The heavy metals in the soil were extracted using "the sequential extraction method". The heavy metals were extracted from the four different soil fractions using different reagents. The results showed that the concentration of heavy metals in the studied area was in the following decreasing order: Fe

021172 Agbazue V E;Ekere N R;Samira M I (Pure & Industrial Chemistry Dep, Nigeria Univ, Nsukka, Nigeria, Email: nwachukwuekere64@gmail.com) : Physico-chemical parameters and heavy metal levels in water and fish samples from river Jakara and Jakara dam, Kano state, Nigeria. Asian J Chem 2015, 27(10), 3794-8.
The physico-chemical parameters and heavy metal levels in water samples from river Jakara and Jakara dam as well as in fish samples from the dam were determined during the wet and dry seasons of the year. From the results and the calculated t-value of the parameters, the physico-chemical parameters and heavy metals determined were generally higher in dry season than the wet season. The recorded pH ranged between 6.1 ± 0.2 to 8.45 ± 0.35, conductivity 970 ± 90 μS/cm to 3300 ± 60 μS/cm, dissolved oxygen 5.5 ± 0.5 mg/L to 12 ± 0.1 mg/L, hardness 42 ± 0.0 mg/L to 326 ± 74 mg/L while the concentration ranges of heavy metals in mg/L and mg/kg were as follows: Pb (0.035 ± 0.01 to 0.070 ± 0.01), Cr (0.115 ± 0.03 to 0.256 ± 0.0), Cu (0.049 ± 0.01 to 0.209 ± 0.04) and Pb (0.108 ± 0.0 to 0.323 ± 0.0), Cr (0.233 ± 0.0004 to 0.930 ± 0.0), Cu (0.484 ± 0.16 to 1.774 ± 0.163) in water and fish samples respectively. The results showed that temperature, pH, dissolved oxygen, chloride, sulphate, nitrate were within World Health Organization/Standards Organization of Nigeria (WHO/SON) permissible limits for drinking water. However conductivity, alkalinity, hardness, TDS, turbidity and heavy metals (Fe, Cr, Pb) were outside (WHO/SON) permissible limits for drinking water; whereas Cu and Zn were within the standard. The heavy metal (Zn, Cu, Fe, Cr, Pb) concentrations in fish samples were within permissible limits set by WHO even though the transfer coefficients calculated revealed higher concentrations of heavy metals in fish than in water.
