    Soil toxicity and remediation techniques
    (Elsevier, 2022) Manikandan, S.K.; Shilli, A.; Noronha, F.R.; Nair, N.
    Soil is a major component required for the growth of plant, and its studies have been carried out intensively for enhanced agricultural production. The need to fulfill the food demands of the increasing human population and the requirement to safeguard food crops has resulted in the heavy usage of pesticides. However, the continuous usage of pesticides and their ability to persist in soil for a longer period has become a threat to society. The pesticide residue in the soil can cause severe environmental problems due to their high accumulative and persistent existence, that are biomagnified through the food chain of various life forms. Different disposal techniques classified as physicochemical technologies, biological technologies, and thermal technologies have been reported to be effective in pesticide removal from soil. Similarly, the application of green chemistry and nanotechnology have been stated to be effective for the removal of pesticides from the soil. This chapter provides detailed information on the various remediation involved in pesticide removal from soil. In addition, it also provides insights on the new technologies for treating contaminated soil and the economic aspect involved in the disposal of pesticides. © 2022 Elsevier Inc. All rights reserved.

    Biocatalytic Remediation of Industrial Pollutants
    (Springer Science and Business Media Deutschland GmbH, 2023) Pallavi, P.; Manikandan, S.K.; Nair, V.
    The release of an significant amount of pollutants from various industrial activities pose a serious threat to environmental sustainability and ecological integrity. Toxic pollutants, such as dyes, pesticides, metal ions, plastics, and antibiotics, can cause detrimental diseases to diverse living beings in their ecosystems. Biocatalytic remediation is one efficient method of removing toxic industrial pollutants by applying microorganisms or enzymes. Microorganisms in the environment typically produce a variety of enzymes to immobilize and degrade contaminants by using them as a substrate for growth and development. Biocatalytic remediation has attracted enormous interest worldwide due to its affordability and eco-friendliness. The use of microbial enzymes and microorganisms, especially immobilized biocatalysts, has been established as a flexible approach for the sustainable alleviation of industrial pollutants, in contrast to physical and chemical methods. This chapter presents and discusses recent scientific and technological advancements related to biocatalytic remediation of industrial pollutants. It also considers different biocatalysts and novel methodologies to mitigate various pollutants. This article also examines current trends, challenges, and directions for efficiently removing pollutant using biocatalysis method. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
