Subject: Knowledge, Attitude and Behaviour Related to Plastic Waste Management : A Study on High School Students in Bangkok, Thailand
Keywords: Plastic waste, Environment, Attitude, Behaviour, Recycling, Thailand
Abstract: Plastic has many valuable applications and is found in several of the daily products we use. Yet, plastic waste is detrimental to the environment as well as can become life-threatening to humans, animals and marine life. The aim of this exploratory study is to examine the internal (knowledge of plastic waste, concern for the environment) and external factors (interpersonal influence and media) on attitude toward plastic waste. The study also examines the influence of attitude on behaviour related to plastic waste management. The respondents in this study were high school students in twelve schools located in various districts of Bangkok metropolis, Thailand. A total of 467 questionnaires were distributed, out of which 364 were considered valid for analysis. The three main hypotheses posited in the study were tested by multiple regression. The findings showed that all internal and external factors significantly influenced attitude; attitude in turn was also shown to significantly influence behaviour related to plastic waste management. The study concluded by offering several useful suggestions for better plastic waste management practices in the Thai context.

Subject: Seasonal Variation in the Concentration of phosphorus in Chennai Lakes and assessment of water quality using the Trophic State Index
Keywords: Eutrophication, Phosphorus, Secchi disc, Trophic state index
Abstract: Monitoring eutrophication is an important part of evaluating and managing lake ecosystems. The present study aims to sample and analyze the water quality of various lakes in and around Chennai city for the sustainable development of water bodies. The experiment was carried out by collecting water samples during various seasons and parameters, such as total phosphorus, chlorophyll and Secchi depth were used to calculate the trophic state index (TSI). The results are used to classify the lakes according to TSI. Several methods have been adopted for the classification of lakes and to indicate their trophic status. The Carlson’s trophic state index, the most commonly adopted method, based on productivity, is used to determine the TSI. Fifteen lakes were selected and samples were collected during rainy, winter and summer seasons during the year 2017. Seasonal fluctuations in the parameters (total phosphorus, Secchi depth, chlorophyll-a) were analyzed. Based on the parameters Carlson’s trophic state index (CTSI) was calculated for each lake and accordingly lakes were classified. The CTSI values in this study range between 32-88. Among the selected lakes many were classified as eutrophic and hyper-eutrophic based on CTSI value. Lakes Chetpet and Porur are classified as oligotrophic and mesotrophic, respectively. The seasonal fluctuations in the trophic state and effect of climate change, alarm the possibility of progression from oligotrophic to mesotrophic lakes would be helpful for policymakers and lake restoration programmes.

Keywords: Photo-electrocatalytic oxidation, Rhodamine B dye, RuO2/IrO2/TaO2 coated titanium electrode, Colour removal
Abstract: This work is focused on the study of photo-electrocatalytic degradation of Rhodamine B (RhB) dye by RuO2/IrO2/TaO2 coated titanium electrodes. Combining electrochemical and photo-catalysis technologies called photo-electrocatalytic technology offers the opportunity to separate electron–hole, photo-generated and promote the formation of highly reactive, oxidising species that contribute e-/h+ and to prevent their recombination. Experiment was carried out with various operating parameters, such as initial pH, applied current density, dye concentration, supporting electrolyte concentration, stirring speed and treatment time. The experimental results revealed that the colour removal increases with increase in current density and NaCl concentration, while it was found to decrease with the increase in initial dye concentration. Under the neutral medium, the decolourization efficiency reached 100% in 30 min of electrolysis time. The pH was found to be an important parameter for the process, the maximum efficiency of colour removal was achieved at pH 7.0. The GC-MS confirms the degradation of Rhodamine B from aqueous solution.

Subject: Anticipated Performance Index of Tree Species for Green Belt Development using Air Pollution Tolerance Index
Keywords: Air pollution tolerance index, Ambo town, Green belt, Performance index
Abstract: In the present study the anticipated performance index of tree species from Ambo town was evaluated for the purpose of green belt development. For evaluating anticipated performance index of the species, alongwith biochemical parameters, biological and socio-economic parameters, such as plant habit, canopy structure, type of plant, texture, hardness and economic value of each species were considered. Descriptive statistics using crosstabs were used for data analysis using statistical package for social sciences software (SPSS version 21). Results of the present study have shown that highest air pollution tolerance index was found with Jacaranda mimosifolia (35.28) followed by Schinus molle (35.21) which were designated as ‘tolerant’ species whereas least air pollution tolerance index was associated with Croton macrstachs (12.28) followed by Olea africana (13.25) which are designated as ‘sensitive’ species. As far as anticipated performance scoring is considered, highest score was attained by Azadirachta indica (4) at site 1 and at site 2 highest score was attained by Schinus mole (4). At site 3, Psidium guajava attained highest anticipated performance index score of 4. Based on the chi-squared (X²) test value it was concluded that there is no significant relation exists between anticipated performance and tolerance index. Dust holding capacity has shown an inverse correlation with leaf area of plant species.

Subject: GIS Based Study of Reclamation of Degraded Semi-Arid Soil: A Case Study from Rajasthan, India
Keywords: Biodiversity information system, Web GIS, weighted index overlay, remote sensing, soil salinity, Landuse land cover
Abstract: Soil degradation takes place not only as a result of interaction between physico-chemical and biological factors comprising topography, soil properties and climatic features but also includes human factors and landuse management practices. Web GIS can be used in rural development administration for planning, monitoring and exchange of data. A study was conducted in Dungargarh tehsil and Churu district of Rajasthan, India to demonstrate the integration of village-level spatial and non-spatial data alongwith the preparation of thematic maps which would be linked to a biodiversity information system database. The region suffers from the acute environmental problems of soil erosion, shifting sand dunes and excessive soil salinity alongwith the economic problems of lack of livelihood options. In this study, the integration of village level spatial and non-spatial data was done, into a useful tool called biodiversity/plant diversity information system (BIS), for environmental resource identification for sustainable environment and livelihood options. Various environmental parameters, like landuse/land cover (LULC), distribution of natural vegetation, soil, water and climate were examined and suitable thematic maps were prepared with an aim of making a present environmental database and probable environmental management and conservation techniques according to the strength and lacuna of the region in a sustainable way for the economic and environmental resurgence of this backward region. The various thematic maps were utilized for demarcation of the mentioned problems and prospects. Further weighted index overlay method was adopted to identify the suitability of the target species for dealing with each of the environmental problems and medicinal gardening. The thematic maps and attribute data were integrated through ArcGIS 10.2 and then published on Web GIS platform through Arc GIS online in a dynamic interactive Web application for ready reference and use by others.

Keywords: Alpha emitters, SSNTD, Water and marshes in Dhi-Qar
Abstract: Radon (222Rn), radium (226Ra) and uranium (238U) concentration have been measured using solid state nuclear track detector (SSNTD) (TASTRAK CR-39 plastic) technique together with evaluation of the risk of average internal effective dose (AED) with lifetime cancer risk due to ingestion of 222Rn and 226Ra in water samples collected from various places of marshes in Dhi-Qar governorate. The average values of 222Rn, 226Ra and 238U in water samples were found to be 288.92±34.10 Bq/m3, 0.46±0.05 Bq/L and 0.61±0.07 ppm, respectively. The average values of AED (mSv/y) due to ingestion of 222Rn and 226Ra in samples under study were found to be 0.019±0.002 and 0.094±0.01, respectively. The average of total AED and lifetime cancer risk were 0.11±0.01 mSv/y and (4.3±0.05)×10-4, respectively. The average value of 222Rn and 226Ra were found to be within the global average limitations (0.4 Bq/L) and (1 Bq/L) recommended by WHO, while the average of 238U concentrations was higher than that of global average limitations (0.566 ppm) recommended by EPA. Most results of AED due to 222Rn and 226Ra concentrations in samples under study were compared with the worldwide median value recommended by WHO. But, lifetime cancer risk in all samples of the present study were higher than the safety limit for healthy drinking water. So, drinking from the water of marshes in the Dhi-Qar governorate, Iraq which is contaminated with alpha emitters, like 222Rn, 226Ra and 238U may lead to a considerable variation in the internal effective dose.

Subject: Adaptation and Livelihood Resilience by Rainfed Farmers to Climate Variability in Food Storage Areas in Bengkulu Province, Indonesia
Keywords: Climate variability, Rainfed farmer, Adaptation, Livelihood resilience
Abstract: Climate variability causes changes in the amount of rainfall and rainfall patterns that affect the lives of rainfed farmers. Farmers are not only synonymous with poverty but also because of the great uncertainty over the impacts and the magnitude of climate variability. The objectives of this study were : to determine the use of adaptation of climate variability by farmers, to measure the resilience of farmers‘ livelihoods related to climate variability and to determine the factors related to the livelihood resilience of farmers. A survey by interviewing purposively selected 100 farmers was conducted in food storage areas in Bengkulu Province from September to November 2020. The results showed that the use of adaptation by farmers was still low and tended to choose the use of climate variability adaptation that did not require additional expenditure, namely shifting the planting season. The livelihood resilience of farmers in dealing with climate variability is also in the low category due to the low institutional function and participation of farmer groups. The use of adaptation is negatively related to livelihood resilience. Poverty and limited resources are reasons for farmers to prefer adjusting conditions to nature in order to increase livelihood resilience in dealing with climate variability.

Subject: Heavy Metal Bioaccumulation and Air Pollution Tolerance Index of Selected Plant Species from Urban Area
Keywords: Ascorbic acid, Chlorophyll content, Metal accumulation index, Relative water content
Abstract: The study was conducted to evaluate metal accumulation index and air pollution tolerance index of five selected plant species, namely Buddleja asiatca, Ficus religiosa, Leucoseptrum canum, Nyctanthes arbor-tristis and Tecoma stans along roadside of Lalitpur district. The air pollution tolerance index (APTI) was calculated based on various biochemical parameters, namely total chlorophyll, leaf extract pH, ascorbic acid and relative water content. Total chlorophyll contents and leaf extract pH of leaves were affected adversely by dust pollution. These parameters of leaves seemed to decreased with increasing pollution levels. Ascorbic acid and relative water content of leaf samples were increased with increasing pollution levels to withstand stress caused by pollution. The plants varied in their metal accumulation and air pollution tolerance. Metal accumulation in plant species was higher in heavily polluted sites. According to average metal accumulation indices (MAIs), the studied plants was found in descending order Ficus religiosa (12.98) >Nyctanthes arbor-tristis (5.84) >Lecosceptrum canum (5.10) >T. stans (4.0) >B. asiatica (3.95) in leaf samples; while in bark samples MAI values were in order Ficus religiosa (38.69)>Lecosceptrum canum (16.18)>Buddleja asiatica (14.16)>Tecoma stans (7.45)>Nycatanthes arbor-tristis (6.33). The mean values of APTI within the city of Lalitpur district were as follows: B. asiatica (6.24); L. canum (8.32); N. arbor-tristis (8.46); T. stans (8.87) and F. religiosa (10.44). The study indicated relatively high metal accumulation and tolerance of Ficus religiosa emerged as the tolerant species with high MAI and APTI value. Hence, Ficus religiosa can be suggested for plantations along the roadside of urban areas for green belt development.

Keywords: Physical, Bacteriological, Chemical, Groundwater, Investigation
Abstract: Shillong city is ever-expanding in all directions leading to population increase and increased utilization of the natural resources, especially the water resource available. To meet the daily requirement of water for domestic as well as commercial demand, the people of Shillong city are increasingly turning their attention to the underground aquifers. However, the water, that is being pumped out is many times being utilized without proper knowledge of its physico-chemical and bacteriological properties. Ignorant on this matter will put the user in a situation where his health may be compromised. This work was initiated with the sole purpose to understand the baseline concentration of different physical, chemical and bacteriological parameters of the groundwater available in and around Shillong city. Thirty-five (35) sampling locations were identified and sampled for three different seasons (winter, pre-monsoon and post-monsoon). The significant observation in this study is that there is a spatial and seasonal variation of all the parameters selected. Concerning pH, iron and total coliform, the majority of the samples reported values that are higher than the prescribed limit for drinking water.

Keywords: Pesticides, Adsorption, Malathion, Isotherms
Abstract: Extensive loads of pesticides are utilized to increase the crop productivity in modern agricultural practices. Slow degradation of pesticides into the environment and extensive or inappropriate use by farmers can lead to contamination of water, soil, air, several types of crops and in turn human beings. Malathion pesticide has been widely used as fumigant, in agriculture and in residential landscapes to replace more toxic organochlorine pesticides, even otherwise result in a serious setback to human health causing skin and nervous defects. Adsorption technique is one of the most intensively availed and reliable method adopted due to its ease of operation, non-energy intensive and high removal competence of organic pollutants, like pesticides. Delonix regia pod shells (DRPS), an eco-based material is employed to chelate malathion from aqueous media through batch mode under varying operational factors, namely, pH (3-11), initial malathion concentration (50-300 mg/L), DRPS dosage (50-250 mg), contact time (10-60 min) and temperature (293-333 K). Optical microscope, FTIR, SEM are utilized to characterize the selected sorbent’s nature. Isothermal data fitted well with the Langmuir plot in preference to Freundlich plot. From the observations made, DRPS is found to be a promising ecofriendly, economically viable material for the sequestration of malathion.

Subject: Performance Analysis of Desalination Plants in UAE: Accentuating the Potential Issues in the Process of Integrated Waste Management and Future Prospects
Keywords: Desalination plants, UAE, Integrated waste management, issues, prospects
Abstract: There are more than 199 desalination plants that are located in different regions, such as the United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain, Egypt and other countries. The desalination plants that are located in UAE accounted for 35% of water generation in the year 2013 and are the main source of drinking water in the country. Desalination plants carry out activities that are associated with the cleaning and purification of water that has been collected from the sea. By using several filtering and purification processes, the desalination plants make seawater fit for drinking and help in meeting the water demand of the individuals. The present study aims to understand the performance of desalination plants in the UAE and outline the way forward to overcome the prevailing challenges. To reach the major objectives, a quantitative research approach has been implemented using quantitative data. Structured questionnaires have been used as primary data which is close-ended in nature. A simple random sampling method had been used for the selection of candidates suitable for the study. The sample unit mainly consisted of 150 specialists who are involved in the process of desalination in the UAE. Statistical tools, such as Chi-square and SPSS methods had been adopted for the analysis of the collected data and to acquire accurate results. Further, findings and discussions have been evolved using statistical tools. Limitations and future aspects are also implemented.

Subject: Energy Efficient Activated Charcoal for Removal of Cationic Dyes under Static Conditions
Keywords: Karanj fruit shell, Activated charcoal, Cationic dyes, Isotherm models, Adsorption
Abstract: In the present study, removal of water-soluble cationic dyes under static conditions was studied using non-toxic, low-cost and energy-efficient Karanj fruit shell activated charcoal (KFS-AC). The study reveals that removal of upto 90% of dye (methylene blue and malachite green) on KFS-AC without agitation at room temperature was observed. The effect of various parameters, such as pH, volume of dye, contact time and adsorbent dosage was investigated. The KFS-AC showed a wide pH range of adsorption with highest adsorption at pH 11.3. The adsorption properties of activated charcoal were studied using equilibrium isotherm models (Langmuir and Freundlich). The Langmuir model yields a much better fit than Freundlich model for both dyes having high regression values. The results revealed that energy-efficient activated charcoal prepared from Karanj fruit shell is highly effective in the removal of Methylene Blue and Malachite Green dyes from their aqueous solutions and can be used as a reliable alternative to high-cost commercial adsorbents.

Subject: Assessment of the Effects of Wadafiea Solid Waste Dumpsite on the Surrounding Soil Environmental Quality – Khartoum North, Sudan
Keywords: Environmental pollution, Solid waste, Soil, Landfill, Dumpsite, Alkalinity, Heavy metals, Monitoring, Sudan
Abstract: Environmental pollution generated from uncontrolled dumping is a major problem in Sudan due to the lack of a proper waste management system. This study was conducted in Wadafiea dumpsite, Khartoum north, Sudan to determine the physico-chemical parameters and heavy metals concentration in some selected soil samples. This study aimed to assess the risk of heavy metals pollution on physico-chemical properties of soils around the dumpsite and to compare the seasonal variations in concentrations of heavy metals on physico-chemical parameters. The level of pH, CaCO3, EC and heavy metals (Cd, Cr, Cu, Ni, Pb and Zn) in soils around dumpsite were determined using pH meter, conductivity meter and atomic absorption spectrophotometer method (AAS). Ten samples of soils were collected in dry and rainy seasons from different directions around the dumpsite of solid waste. The obtained results of the soil samples’ analysis showed that alkalinity in the soil of the landfill and around the dumpsite has slightly increased. The concentrations of pH in the dry season were higher than the levels of pH in the rainy season. The heavy metals concentrations in the soil samples in the dry and rainy seasons varied per sample of sampling location and seasons. These findings indicated that the concentration values of heavy metals in the rainy season were higher than in the dry season. The values of all the heavy metals analyzed for samples from the dumpsite and the area adjacent to the landfill were higher than those from the control site suggesting possible mobility of heavy metals from dumpsite to the farmlands through leaching and runoffs, but they were below the values recommended by the World Health Organization and Canadian guideline values.
