Book Description :

Pharmaceuticals and heavy metals derived from point sources and non-point sources find their ways into water bodies. One of the important sources of such pollutants is wastewater or effluents from wastewater treatment plants. The presence of pharmaceuticals and heavy metals in the water bodies causes irreversible damages to flora, fauna and human health. Risk assessment plays a vital role in identifying the pollution intensity. The adsorption process is one of the most appropriate processes in eliminating such pollutants from wastewater. In this study, a fixed-bed column is used to verify the feasibility of using a novel biochar material to remove organic (pharmaceuticals) and inorganic (heavy metals) compounds. This study was conducted in 3 phases. In the first phase, the pollution intensity of pollutants in wastewater effluent was evaluated by risk assessment formulas. In the second phase, the impact of the initial concentration, flow rate and bed depth on the laboratory-scale adsorption column performance were investigated. In the third phase, the Adam-Bohart model was used to design the large-scale fixed-bed column. Moreover, the pollution intensity of pollutants was determined. The results clearly indicated that the presence of venlafaxine and heavy metals in wastewater effluent poses adverse effects on aquatic and marine organisms. The adsorption of venlafaxine, Ni, Pb and Cu on biochar in a laboratory-scale column was observed as well as in the larger-scale column. Increasing the initial concentration and bed depth along with decreasing the flow rate caused the adsorption capacity to be on the rise. The removal over 90% of venlafaxine, Ni, Pb and Cu was found at the breakthrough point where the adsorption capacity was increased from 0.8 to 5.4 mg/g for venlafaxine, from 1.92 to 18.24 μg/g for Ni, from 3.84 to 30.72 μg/g for Pb, and from 2.88 to 24 μg/g for Cu. The large-scale column, tested on real effluent at wastewater treatment plant, confirmed the feasibility of using biochar to eliminate 95% of venlafaxine and 90% of Ni, Pb and Cu at the breakthrough point. The adsorption capacity at the breakthrough point was 3051.406 ng/g for venlafaxine, 24.364 μg/g for Ni, 0.1296 μg/g for Pb, and 7.115 μg/g for Cu. The pollution intensity of venlafaxine, Ni, Pb and Cu to aquatic and marine organisms decreased from a high to low risk due to the utilization of novel biochar in the fixed-bed column.

Book Description :

Over the past few decades the boom in the industrial sector has contributed to the release in the environment of pollutants that have no regulatory status and which may have significant impact on the health of animals and humans. These pollutants also refer as “emerging pollutants” are mostly aromatic compounds which derive from excretion of pharmaceutical, industrial effluents and municipal discharge. Some form of pollutions have also evolved, including the proliferation of acid mine drainage from oxidation or weathering of obsolete and unmanaged excavations around the world; this results mostly in the dispersion of inorganic pollutants in the environment at level surpassing the treatment capacity of conventional techniques. It is recurrent these days to find water treatment plants which no longer produce water that fits the purpose of domestic consumption based on newly established guidelines. This situation has prompted water authorities and researchers to develop tools for proper prediction and control of the dispersion of pollutants in the environment to ensure that appropriate measures are taken to prevent the occurrence of outbreaks due to sudden load of these pollutants in the water system. The chapters in this book cover a wide range of nano and bio-based techniques that have been designed for the real time detection of emerging contaminants in environmental water sources, geochemical models that are continuously improved for the prediction of inorganic contaminants migration from the mine solid wastes into ground and surface waters. Remediation strategies are also discussed and include effective techniques based on nanotechnology, advanced membrane filtration, oxidative and bio- degradation processes using various types of nanocatalysts, biocatalysts or supporting polymer matrices which are under advanced investigations for their implementation at large scale for the removal of recalcitrant pollutants from polluted water. This book is divided is two sections, the first section covers the occurrence of emerging pollutants in environmental water while the second section covers state of the art research on the removal of emerging pollutants from water using sustainable technologies. A total of 13 chapters addressing various topics related to the two sections are essentially based on recent development in the respective field which could have a significant impact on the enhancement of the performance of wastewater treatment plants around the world and especially in developing countries where access to clean and safe water remains a daily challenge

Land is fundamental to the human life. The upper layer of land is a non-renewable resource, and source of food. Therefore, land health is essential to long-term food security and to promote sustainable livelihoods. On account of urbanization, industrialization and population growth, land pollution is one of the major issues worldwide. As a result, land pollution is continuing across the world, and has been linked with a wide range of potentially toxic contaminants at rates that deteriorate land quality. Land pollution can result either anthropogenic activities or natural activities. The major contaminants of land pollution are metalloids, petroleum hydrocarbon, radioactive elements, polyaromatic hydrocarbons (PAHs), Pesticide, other organic pollutants, etc. that comes from different types of sources. In urban and peri-urban areas, irrigation of agricultural land with polluted water is also a reason of land pollution. Therefore, land security is an important issue for future sustainability. Its remediation and management are important issue worldwide to protect land quality and functions. Land pollution means degradation of earth's surface. Polluted land comes under the category of degraded land. Hence, the remediation of polluted land is essential for regaining biodiversity and ecosystems services and thereby achieving United Nations-Sustainable Development Goals (UN-SDGs).This fact showed the need to develop research into land remediation. Bio-inspired land remediation has undergone a huge development. Therefore, Biomanagement has a lot of potential to secure upper earth’s surface through the land remediation programs targeted during the United Nations Decade on Ecosystem Restoration (2021-2030). This book explores the remediation of land pollution that includes Phytoremediation, Bioremediation (bacterial remediation and fungal remediation), Vermiremediation, Biochar-based remediation and other Bio-inspired remediation. This book will be a remarkable asset for research scholars, environmentalists, ecological scientist, agriculturist, practitioners, policy makers, entrepreneurs, and other stakeholders alike.

Book Description :

Currently, anthropogenic activities have caused unprecedented destruction of the environment at alarming rates, leading to undesirable alterations in air, land, and water. The process of environment degradation has been accelerated by industrial processes, which result in waste as well as over-consumption of natural resources. The ecological balance has been disturbed, and resources have shrunk. All this has resulted in climate change, which has emerged as a major concern in the 21st century. Changes in the environment are driven by demand for energy, water, and food to raise the standard of living. These are also responsible for climate change, with contributions from deforestation and CO2 emissions from fossil fuels such as coal and petroleum. The present volume discusses some of the main issues regarding environmental degradation and the causes as well as the impact of climate change, which is impacting the ecosystem. The effects of various pollutants, causes of climate change with case studies on geochemistry and glaciers, etc., and measures to reduce the impact on biodiversity, health, etc. are discussed in detail in its chapters. In a nutshell, this volume discusses in detail the following issues: • Anthropogenic and natural factors in environmental degradation • Climate change history, causes, and threats to abiotic and biotic systems • Case studies on the impact of climate change and living systems • Mitigation and preparedness for the future
