  • A Survey of Household Solid Waste Practices in Barnawa District, Kaduna,
           Nigeria

    • Abstract: Publication year: 2020Source: World Environment, Volume 10, Number 2Fanan Ujoh, Martyn Clark, Stephen Hemba, Adebola AdenekanThe Barnawa district’s settlement pattern is made up of several households in a set of built houses generally regarded as compounds. A semi structured questionnaire was self-administered to a total of 166 households in 105 compounds in Barnawa districts. The compounds were selected through multilevel sampling procedure involving convenient and random techniques. Findings showed in general, households in Barnawa would be willing to pay for improved solid waste management (SWM) services irrespective of household size or their relative wealth-status as measured. However, willingness to pay for improved SWM services was generally common among households least satisfied with the current service they receive. Also household size, location of a household in relation to an existing official solid waste collection point are observed to be major drivers of how much households are willing to pay for improved SWM services in the district.
       
  • Evaluation of Heavy Metal Concentrations and Proximate Compositions of
           Amaranthus spinosus L. and Talinum triangulare J. and Soils Collected from
           Dumpsites in Some Selected Areas in Lagos State, Nigeria

    • Abstract: Publication year: 2020Source: World Environment, Volume 10, Number 1Oluwole Surukite O., Makinde Sunday C. O., Ogun Mautin L., Nwachukwu Ifeanyi R.Anthropogenic activities usually results in pollution, especially in developing countries where low-end waste management is the common practice. Thus, this research evaluates the concentration of heavy metals (Mn, Cu, Zn Pb, and Cd) and proximate compositions of Amaranthus spinosus and Talinum triangulare. Soils were collected in three dumpsites from three different Local Government areas (Alimosho, Amuwo-Odofin and Ojo) in Lagos State, Nigeria. The sampled vegetables and soils were determined using Standard techniques and atomic absorption spectrophotometer for the metal concentration analysis. The level of each metal concentration to the dumpsites was compared to World Health Standard. The results revealed that the two vegetables sampled contained appreciable quantities of nutrients needed for normal human development. Also, the heavy metal analysis shows the concentrations ranges from Mn (0.034-709mg/Kg), Cu (1.624-3.637mg/Kg), Zn (0.671-1.256mg/Kg), Pb (0.000-0.007mg/Kg) and Cd (0.000-0.007) in Amaranthus spinosus; Mn (0.336-0.073mg/Kg), Cu (0.206-1.834mg/Kg), Zn (0.006-0.680mg/Kg), Pb (0.000-0.003mg/ Kg) and Cd (0.000-0.002mg/ Kg) in Talinum triangulare; and Mn (0.000-1.300 mg/Kg), Cu (1.348-1.732 mg/Kg), Zn (0.149-1.100mg/Kg), Pb (0.000-0.008mg/Kg) and Cd (0.000-0.002mg/Kg) in the soil samples of the three dumpsites. However, Amaranthus spinosus, Talinum triangulare and soils of most of these dumpsites accumulated minimal concentrations of these metals. In fact Pb and Cd were not detected in some vegetables and soils. All the concentrations of metals studied in soil and vegetables were found to be lower than the maximum permissible limit of heavy metal in soil and vegetable stated by the World Health Organization (WHO) which implies that the vegetables are presently safe for human consumption. Thus, the higher concentration of metals in wastes of dumpsites and their vegetables, the increased threat it posed to the consumers. Hence, it therefore recommends that consumption of Amaranthus spinosus, Talinum triangulare and other vegetables from dumpsites should be avoided.
       
  • Issues in Transboundary Water Use in the River Nile Basin Area of Africa

    • Abstract: Publication year: 2020Source: World Environment, Volume 10, Number 2E. C. Merem, Y. A. Twumasi, J. Wesley, D. Olagbegi, M. Crisler, C. Romorno, M. Alsarari, P. Isokpehi, A. Hines, G. S. Ochai, E. Nwagboso, S. Fageir, S. LeggettWater resource access as an integral part of everyday life serves multiplicity of purposes from agriculture to the hydroelectric power needs of most areas. However, in the Nile Basin region where major water sources for nations pass through international boundaries, limited access to water and lack of it can be a source of economic, political and ecological conflicts. Accordingly, in the last several years, the complexities and processes involved in transboundary water use under the ambit of hydropolitics in the Nile Basin region, continue to stoke anxieties and tensions among the nations in their strategic relationships. Given the high stakes, occasional responses to addressing hydrological stress can sometimes involve unilateral investment in the latest advances in technology to extract water, recourse to negotiated settlements and multilateral accords. Conversely, unilateral responses to water insecurity in such a region when not properly negotiated often create uncertainties and distrust that threaten regional stability. Even in the face of such volatilities, nations that were once at odds in the past over water insecurity are resorting to negotiations instead of the drumbeats of war in the Nile Basin of Africa. This is compounded by rapid growth in population, the threats of climate change through recurrent drought amidst high propensity to instability and poverty. Having said that, very little exists in the literature on current state of water politics of the study area using a mixscale model of GIS and descriptive statistics. At the same time, there has been limited coverage on the scale of water use, the different uses, and the distribution patterns in the study area. To bridge that void, the study will focus on transboundary water use within the purview of hydropolitics along the Nile Basin with emphasis on the issues, trends, factors, impacts and efforts. While the paper used mixscale techniques of GIS and descriptive statistics to analyze the trends. The results reveal notable disparity in hydrological parameters with evidence of water stress and abundance in various areas of the study area. For that, irrigation water use was more pronounced in the Northern nations of Egypt and Sudan coupled with cases of unmet water needs in the heavily populated places (Egypt and Ethiopia). Both nations experienced more cases of unmet water needs compared to the countries in the South. Notwithstanding, the higher volumes of rainfall and more per capita fresh water in the Sub Saharan Africa portion, than the North African zone, areas classified as water bodies and wetlands declined substantially throughout the Nile Basin. This could lead to depletion and growing anxiety. Considering the role of socio-economic, political and physical elements in all these, the paper proffered solutions ranging from education, conservation, mediation and negotiated settlements as well as effective policies, and mutually binding agreements among nations in the region on water use.
       
  • Evaluation of the Effect of Quicklime on Some Organisms from Different
           Ecosystems in Egypt: Morphological Perspective

    • Abstract: Publication year: 2020Source: World Environment, Volume 10, Number 1Amina El-MansyQuicklime needs wise management decisions before using either in the terrestrial or aquatic environment, especially in fish farms against benthic organisms infected with pathogenic parasites. It has been found that its reaction with water led to water heating, and other disturbances appear to occur. Many health problems have been observed on fish due to lime water. Lime kills snails when it is in a dry state or hydrate, also at high concentrations in addition dangerous to fish. On the other hand, in agriculture, lime water may not be recommended because of its ‘in vitro’ negative effect on the green material of the plant as well. Therefore, it seems better to be away or needs a lot of precautions before applying it specifically as a disinfectant in dense fish farms. It is clear that biological control looks better, perhaps by grazing certain predators. Moreover, to protect the health of workers from invaders, special clothing should be taken seriously during irrigation or fishing as an important preventive measure.
       
  • Using Cilantro (Coriandrum Sativum) to Remove Cadmium from Contaminated
           Water

    • Abstract: Publication year: 2020Source: World Environment, Volume 10, Number 1Njue Martin, Mbuvi Harun, Margret Nga’nga’, Mbugua GeraldAccessibility to safe drinking water poses great risks to human health since heavy metal ions can accumulate their amounts along the food chain. Methods already in use for cleaning contaminated water have resulted in generating toxic sludge and are expensive. Cilantro leaves has been used to reduce the contamination of heavy metals like lead, mercury and copper in rod shellfish as contains bioactive components of flavonoids, saponines and fibers which are capable of absorbing heavy metal ions by chelating action. However, the most effective part of cilantro and the most effective form i.e. when green or dry has not been reported. Consequently, the present study aimed at investigating adsorption of Cd2+ ions by fresh and dry cilantro leaves and stems from simulated water. Cilantro fresh leaves and fresh stems were grounded to obtain the wet adsorbents while for the dry adsorbents, fresh cilantro leaves and stems were sun dried at room temperature until their weighed dry masses remained constant and grounded to fine powder. Batch sorption studies were carried out while varying parameters of contact time, shaking speed, temperature, adsorbent dose, pH and initial concentration of metal ions in solution. Residue Cd2+ ions concentrations were determined using atomic adsorption spectroscopy (AAS). The adsorption of Cd2+ ions was described by Langmuir isotherm with Qmax values of 250.00, 51.28, 4.68 and 15.06 mg/g for fresh leaves (FL), fresh stems (FS), dry leaves (DL) and dry stems (DS) biomasses respectively. The results from this study suggest that fresh and dry cilantro leaves and stems are potential adsorbents of Cd2+ ions.
       
  • Treatment of Contaminated Ground Water Using Phytoremediation Technique at
           Anantapur, India

    • Abstract: Publication year: 2019Source: World Environment, Volume 9, Number 2Piyush Gupta, Paturu Siva Niveditha, S. SharadaOne of the burning problems of our industrial society is the high consumption of water and the high demand for clean drinking water. Groundwater is used for domestic, industrial water supply and for irrigation all over the world. Although three-fourths of the earth is being surrounded by sea only a little portion of it can be used for drinking purpose. The use of aquatic plants for water and waste water treatment is increasing nowadays. The aim of the project is to examine the phytoremediation potential of water hyacinth (Eichhornia Crassipes) and water lettuce (Pistia Stratiotes). The study area faces water scarcity as well as water quality problems. Therefore, attempts were made to treat the groundwater at Anantapur, India using these species. The growth parameters of species like the number of leaves, plant weight, length of principal root and number of roots were studied. The results of the treatment methods were compared with respect to removal efficiency of these species for different water quality parameters. The study revealed that water hyacinth had higher contaminant reduction capability than water lettuce for various physicochemical water parameters.
       
  • Analysis of Physico-chemical Characteristics of Water Collected from
           Different Sampling Sites of Lake Hawassa, Ethiopia

    • Abstract: Publication year: 2019Source: World Environment, Volume 9, Number 2Melaku Zigde Haile, Endale Tsegaye MohammedThe research aimed to evaluate the current water quality status of Lake Hawassa in order to identify potential pollution sources, and put in place monitoring programs. Eleven potential sampling sites were included in the study. Water quality parameters, such as total dissolved solid (TDS), pH, temperature, conductivity, turbidity, dissolved oxygen (DO), five day biological oxygen demand (BOD5), total hardness as CaCO3, total alkalinity as CaCO3, nitrate, sulphate, orthophosphate, fluoride, K, Mg, Cu, Cd, Cr, Fe, Mn, Pb, and Zn were determined and compared with WHO standards. The results were compared with the WHO and FAO standards. And the values of TDS (381.7 to 1286.0 mg/L), SC (733.7 to 2151.3 µS/cm), turbidity (8.20 to 87.3 NTUs), BOD5 (4.02 to 76.2 mg/L), phosphate (0.348 to 1.90 mg/L), fluoride (11.6 to 17.5 mg/L), chromium (0.173 to 0.665 mg /L), manganese (0.133 to 1.83 mg/L), and copper (1.40 L to 18.2 mg/L) were found above the prescribed limit of WHO guidelines for drinking purposes, while all the analysed water quality parameters were fall within the FAO standard limit for irrigation purposes. These suggested that both point and non-point pollution sources such as human sewage, industrial waste from ceramics, textile, plastics and food processing industries, urban stormwater, agricultural runoff and land development were impacting the lake. Thus, mitigation measures should be put in place to prevent the Lake from further deterioration.
       
  • Geotechnical Evaluation of Gravels Quarries Exposed Along Eastern Nile
           Valley Bank, Qena Region, Egypt

    • Abstract: Publication year: 2019Source: World Environment, Volume 9, Number 2Hesham A. H. IsmaielGeotechnical behavior of Quaternary gravels exposed along the eastern Nile valley bank at Qena region was investigated to evaluate their proportion for using as quarries. To achieve this aim, thirty six specimens of the studied Quaternary gravels were collected from different six sites represented six gravels quarries distributed along the eastern Nile valley bank at Qena region. Chemical and mineralogical analyses of the studied gravels were carried out. A percent of soluble sulfates and chlorides of the studied gravels were measured. Physical and geotechnical parameters including specific gravity, water absorption, degradation in water, particle size analysis, adhering clay lumps percent, elongate/flatness percent, Les Angeles percent, California bearing ratio, potential alkaline reactivity as well as proportion of the loss of the studied gravel were tested. The results showed that the studied gravels distributed at the studied area were belonging to Quaternary alluvial fans and stream sediments and the main source rocks were Upper Cretaceous/Lower Tertiary succession and basement complexes (Red Sea Mountains). The results showed also that the studied gravels were convenient for quarrying. They could be applied in road constructions, asphalt mixtures, and cement concretes except the gravels at Qena-Safaga quarry which were not fit for using in cement concretes. That due to the studied gravels at Qena–Safaga quarry contained a high percent of soluble chlorides. The proportion of the loss of the investigated gravels at the studied quarries was ranging from 41.50 to 48.27%. All the studied gravels quarries passed in the potential alkaline reactivity test.
       
  • Solid Waste Management in the Informal Settlements: A Land Use Planning
           Perspective

    • Abstract: Publication year: 2019Source: World Environment, Volume 9, Number 1Wilfred Ochieng OmolloThis paper is based on a study conducted in Langas, an informal settlement located in Eldoret Town, Kenya. It brings to light key challenges in domestic solid waste management (SWM) facing the settlement. It largely contends that although Langas, a product of unplanned boundary extension, is now within the spatial jurisdiction of Eldoret Town, the County Government of Uasin Gishu (CGUG) has not improved SWM service to the neighbourhood. The target population comprised of 6,842 mapped residential developments. The corresponding sample of 361 was selected using a random number table. Results postulated that key emerging challenges towards effective domestic SWM included absentee landlords who flout development control orders; inadequate receptacles; indiscriminate disposal by households; unreliable collection by CGUG; low household incomes, and limited public education. The study concludes by asserting that past boundary extensions of Eldoret Town in the absence of adequate land use planning and development control are the root cause for inadequate SWM in Langas and other informal settlements. Recommendations made included, but not limited to, preparing a comprehensive land use plan, organizing citizen fora on SWM, regular solid waste collection, establishing a Municipal Board to address service delivery, and adoption GIS and remote sensing as smart technologies to aid in SWM.
       
  • An Investigation on the Effects of Copper on Chenopodium album

    • Abstract: Publication year: 2019Source: World Environment, Volume 9, Number 1Andile Tonga, Jennifer Laifa, Nomagugu Gxaba, Gloria Miller, Maria Begonia, Gregorio BegoniaCopper (Cu) is an essential metal that is needed by humans, animals and plants. The metal has been found to be an irritant to humans. The gastrointestinal effects of copper in humans include nausea, anorexia and diarrhea. Excess copper in plants cause chlorosis, stunted growth, and denaturing of macromolecules. Wild plants are crucial in providing food source for humans. But at times, the wild plants can grow in contaminated soils. Chenopodium album from Chenopodiaceae is a wild leafy vegetable that is consumed in some parts of Eastern Cape, South Africa. It is believed to be rich in proteins, carotenoids and vitamin c. The hypothesis of the study was that Chenopodium album, a leafy wild vegetable consumed by humans in the Eastern Cape, South Africa would uptake and accumulate copper in the harvestable parts. The shoot heights, root lengths, shoot and root biomass and the concentration of copper were measured from C. album growing from soils contaminated with different concentrations of copper. Results revealed that the harvestable parts of C. album have accumulated 160.074 mg per kilogram copper. The results indicate that humans that consume C. album that is growing on copper-contaminated soils are at risk of being negatively affected by copper.
