Singh, Bharti; Malik, Anju; Garg, Vinod Kumar
As the world�s population is increasing by the day, the daily basis demands supplied through industries and agriculture have led to the release of contaminants into the environment resulting in a serious threat to human health and the environment. There are so many technologies for the removal of contaminants from the environment including physical, chemical and sophisticated oxidation procedures. These procedures and technologies, however, have their limitations and the end products are also harmful. As a result, there is a need to identify and investigate sustainable and eco-friendly processes that use less chemicals, are economically viable and provide non-toxic final products. One of the such attractive, stable, sustainable and eco-friendly cleaning technique to deal with this issue is Bioremediation. It is an interdisciplinary approach which includes various living organisms from the surroundings to remediate contaminated ecosystems. Toxic compounds are metabolized by many microbes to release CO2 or CH4, water and biomass. These contaminants may be metabolized enzymatically into less toxic or harmless metabolites. Furthermore, the solid waste produced by this technique has been shown to have a potential influence on soil macro- and micronutrients, indicating its use as organic manure. However, bioremediation requires further research before it could be used on a wider scale, with a focus on the environmental implications of the final products. This chapter provides a brief overview of various bioremediation approaches to remediate the polluted environment. � 2024 Anju Malik and Vinod Kumar Garg.

The present book, Bioremediation for Sustainable Environmental Cleanup, has a compilation of seventeen chapters comprehensively describing the state-of-the-art on emerging bioremediation approaches employed for sustainable environmental clean-up of diverse environmental pollutants such as metal(loid)s, polycyclic aromatic hydrocarbons, dyes, pesticides, petroleum hydrocarbons, etc., by using bacteria, fungi, algae, higher plants, and novel materials like biohybrids, nano-biomaterials, and graphitic carbon nitride (g-C3N4). Different bioremediation strategies such as biosorption, bioprecipitation, bioaccumulation, biodegradation, biotransformation etc. have been described in detail. The emphasis throughout, however, is on sustainable environmental clean-up. Eminent researchers from various countries located in diverse geographical areas, including Argentina, Canada, Germany, India, Pakistan, South Africa, the United Kingdom, and the United States of America, have contributed towards the chapters of this book. � 2024 Anju Malik and Vinod Kumar Garg.

Kumar, Ajay; Attri, Arun K.
The temporal profile of PM10 and its composition comprising water-soluble ionic species and n-alkanes studied over the 14 months was segregated into three seasons: winter, summer, and monsoon. The average PM10 concentration exceeds the prescribed National PM10 limits in summer and winter. The PM10 concentration was highest in summer, followed by winter, and lowest in monsoon. Water-soluble inorganic ionic species� major cations (Ca2+, Mg2+, Na+, K+, and NH4+) and anions (F?, Cl?, NO3? and SO42?) contributed an average 30.7% to PM10. The ionic species displayed significant variation, with the highest concentration in winter and the lowest in the monsoon. The secondary inorganic ions, SO42?, NO3?, and NH4+, contributed 84% to the total ionic mass. The ion balance study revealed a strong correlation between anion and cation charge equivalents, suggesting their main contribution to PM10. The neutralization of NO3? + SO42? with NH4+ suggested, NH4+ being the main neutralizing species. n-alkanes concentration in PM10 was significant and showed seasonal variation, highest in the winters and lowest in monsoon. The source profiling of PM10 components, using statistical correlation, regression, and principal component analysis (PCA), revealed solid-fuel biomass, soil dust, and brick kilns and transported materials as major sources. � 2023 Turkish National Committee for Air Pollution Research and Control

Both environmental chemistry and green chemistry are important and have a crucial role in the ecosystem; however environmental chemistry discusses about the environmental problems, while green chemistry provides the solution. Green chemistry is new emerging area that strives to achieve the sustainability at the molecular level. Green chemistry generally deals with reduction or minimizing the harmful and toxic chemical products with eco-friendly one. From the past few decades, green chemistry has received a remarkable attention of the researchers due to its ability to achieve environmental and economic goals by doing chemical invention. Through different major modification of green chemistry including renewable feedstocks, biocatalysts, green solvents, dual aims of environmental protection and economic benefits could be achieved. This chapter generally covers the concept of origin of environmental and green chemistry with a cohesive set of 12 principles. � 2024 Elsevier Inc. All rights reserved.
