Abstract:

Copper contamination is a common problem in many industrial and mining sites that requires remediation. We performed electrokinetic experiment under a constant electrical current of 20 mA to study its removal from standard kaolinite soil using activated carbon filter media (AC RFM). AC affinity to copper adsorption facilitated the contaminant removal. Then, copper desorption was easily achieved by flashing the AC filter media with low pH solution while the AC was reused. Kaolinite soil spiked with 2.5 g/L of copper sulfate to give 1 g/L copper concentration in the soil. 1 kg of the contaminated soil was packed in the electrokinetic cell and 25 g of granular activated carbon (GAC) filter media was added near the cathode electrode. Electrokinetic experiment was carried out for 7 days and soil was divided into 5 equal sections at the end of the experiment. Copper concentration in the soil was measured by the XRF analyser. Results revealed that copper removal was 90.74%-68.78% in the sections 1 to 4. Copper removal was negative in the soil section 5 close to the cathode due to high soil pH in that soil section. However, a significant amount of copper, approximately 45%, was captured by AC during the EK-AC treatment, resulting less copper precipitation in the soil section near the cathode. Therefore, AC RFM could significantly enhance copper removal in the EK experiment under a constant electric current. The AC RFM was removed from the electrokinetic cell and packed in a filtration column for treatment and reuse. Nitric acid solution was passed through the AC column, achieving more than 82.1% copper removal. The AC was flushed with deionized water to neutralize the pH to normal conditions before reuse. The experimental work showed the feasibility of contaminant entrapment in the AC filter media under a constant electric current without adding chemicals and easily recovery by acid leaching due to AC’s high permeability. This will facilitate the process of contaminant removal from soil at the end of the electrokinetic remediation process that is usually accumulates near the cathode zone.

Abstract:

In recent decades, many species have shifted their geographic ranges, seasonal activities, migration patterns, abundances and interactions in response to changes in the world’s climatic system. Projections of future climate change are uncertain, but the Earth’s warming is likely to exceed 4.8°C by the end of 21th century. Predicting the potential future risks to biodiversity caused by climate change has become an extremely active field of research, and several studies in the last two decades had focused on determining the negative impacts of climate change on reptiles at global, regional and local level. But why reptiles are so vulnerable to climate change? What is the importance of these animals and why should we preserve them? Here we aim to describe the main factors contributing to the vulnerability of lizards and snakes to climate change and their role on the ecosystems they are inserted. We also highlight the importance of an integrative approach including biological, bioclimatic and environmental variables to buffer the climate change effects on this group through the application of consistent and truly effective strategies for species conservation. Finally, we indicate areas with high spatial diversity of vulnerable species around the globe, indicating targets for conservation at a larger scale and helping to determine conservation areas at a small scale.

Abstract:

India is one of the most climatically diverse countries in the world. India hosts six major climatic subtypes, ranging from arid deserts in the west, alpine tundra and glaciers in the north, and humid tropical regions supporting rainforests in the southwest and the island territories. The current problem is that 25% of India is turning into a desert. In the next 15 years, we may have only half the water we need for our survival. For Example, the river Ganga is one of the most endangered water body in the world. Each person’s average water requirement is 1.1 million liters a year. Climate change is expected to cause worse floods and droughts within the next 25-50 years. During the monsoon, rivers will flood. The rest of the year, drought will follow. The proposed solution could be that the revitalization of dying rivers is possible through riverside afforestation. India is the first country in the world to make corporate social responsibility (CSR) mandatory, following an amendment to the Companies Act, 2013 in April 2014. Businesses can invest their profits in areas such as education, environment, renewable energy, poverty alleviation, etc. as part of any CSR compliance. India’s population consists of more than 65% of youth and the need of the hour is to institutionalize volunteerism in India which is over and above the CSR mandate. And, the ‘real change-makers’ are our children and they could play a significant role in changing the behavior of the elderly by demonstrating responsible behavior towards the climatic changes and global warming.

Thi Thuc Quyen Nguyen has completed her master's program at the age of 27 years from Ho Chi Minh City University of Technology, Vietnam. She is studying for her Ph.D. at the University of Technology Sydney, Australia. Her research focuses on the pollution of arsenic in groundwater. In addition, she concentrates to look for novel, low-cost, local materials that can be used as an efficient adsorbent to remove arsenic, by that reducing the cost of application.

Abstract:

Arsenic has acknowledged as one of the serious pollutants in groundwater. At high doses, it causes many human diseases related to skin, lung and other organs such as vascular disease, renal disease, chronic lung disease, hyperkeratosis, skin lesions, etc. Many methods applied to remove arsenic in an aqueous environment; however, the adsorption approach is usually chosen because it is an efficient, economy-effective and relatively easy-to-use method. Recently, arsenic adsorption by plant emerges as a low-cost and environmentally friendly method. In this study, first time, the dried fibre of the luffa plant was used to remove arsenate from groundwater. In order to enhance the positive charge of the adsorbent surface, which was very favorable to arsenic anion attraction, the luffa fibre was coated by iron oxide. As a result, the arsenate removal efficiency of raw luffa fibre increased 70 times after modification. The optimized pH of luffa fibre was identified at 3 and the co-existing phosphate anion was the most influenced to the arsenate adsorption process of luffa fibre. The analysis of scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and zeta potential determined the characteristics of luffa fibre and its modified form. In addition, these analysed results helped to clarify the mechanism of the adsorption process.

Abstract:

The Amazon forest plays a major role in global carbon budget, and thus in mitigating the effects of climate change by stocking nearly half of the tropical forest carbon. Several ecoregions of the biome may lose their current climate conditions in the next few years, even considering a decrease in current global greenhouse gases emission rates. Besides climate change, recent events are threatening the Amazon integrity, such as deforestation, agrobusiness, mining activities, and uncontrolled fire. The Brazilian parliament has emitted intentions on increasing the resource exploitation in the biome, mostly inside indigenous lands, by encouraging and viabilizing mining and agrobusiness activities. This leaded to an unprecedented fire season in 2019, in addition to deforestation rates reaching the highest values in the last 12 years, and increased invasions to indigenous territories leading to the death of several indigenous leaders. This may have drastic consequences for the Amazon biodiversity and traditional populations, besides hamper the achievement of world’s carbon emissions targets to decrease current global warming rates. Here we discuss the exposure and sensitivity of the Amazon to climate change considering a business-as-usual scenario of greehouse gases emissions, the potential impacts of Brazilian political perspectives on the conservation of the biome and its consequences to human livelihood, environmental conservation and the world climatic system. Brazil hosts over 50% of the Amazon, so government’s actions should go toward sustainable policies rather than inadequate environmental regulation aiming short term profits. Otherwise the Amazon (and perhaps the world’s climatic system) will be in danger.

Abstract:

Land leveling is one of the most important steps in soil preparation for agricultural and other purposes. . New techniques based on artificial intelligence, such as Artificial Neural Network, integrating Artificial Neural Network and Imperialist Competitive Algorithm (ICA-ANN), or Genetic Algorithms (GA-ANN), or Particle Swarm Optimization (PSO-ANN) have been employed for developing predictive models to estimate the energy related parameters and the results were compared to SPSS and Sensitivity Analysis  results. In this study, several soil properties such as cut/fill volume, compressibility factor, specific gravity, moisture content, slope of the area, sand percent, and swelling index were measured and their effects on energy consumption were investigated. Totally 90 samples were collected from 3 land areas by grid size of 20m×20m. The aim of this work was to develop predictive models based on artificial intelligence techniques to predict the environmental indicators of land leveling . Results of sensitivity analysis illustrated that only three parameters consist of soil density, soil compressibility, and soil cut/fill volume had meaningful effects on energy consumption.  Among the proposed methods, the GA-ANN had the most capability in prediction of the environmental energy parameters. However, for prediction of LE and FE the ANN and ICA-ANN algorithms had better performance

 .  On the other hand, SPSS software had higher R 2 value than Minitab software and sensitivity analysis and in fact close to the ANN values. Keywords: Energy; Imperialist competitive algorithm; Sensitivity analysis; ANN; Land levelling; Environmental indicators.

Keywords:Artificial Neural Network; energy; environmental research; Imperialist Competitive Algorithm; Sensitivity Analysis

.Originality/value – A limited number of research studies related to energy consumption in land leveling have been done on energy as a function of volume of excavation and embankment. However, in this research, energy and cost of land leveling are shown to be functions of all the properties of the land, including the slope, coefficient of swelling, density of the soil, soil moisture and special weight dirt.
