    Impact and prospects of pesticides on human and environmental health
    (Elsevier, 2023-03-17T00:00:00) Singh, Simranjeet; Garg, Vinod Kumar; Ramamurthy, Praveen C.; Singh, Joginder; Pandey, Ashok
    The changing nature of pesticides has led to the evolution of advanced pesticides which become troublesome for pest control in agriculture and thereby increasing the resistivity of pesticides. Pesticide poisoning emerges either from regular intake of pesticides in minute quantities. Presently, different interventions are being explored to form a sustainable society as persistence and occurrence of pesticide in environment is imposing as major health concern among humans. Our chapter deals with different pathways and sources of pesticide contamination in environment. Efforts have been made to incorporate the different classes of pesticides and their detrimental effects on human health and environment. Here we discuss different detection method and sample extraction process to minimize the increasing level of pesticides compounds in water bodies aiming to protect environment and human health. � 2023 Elsevier Inc.

    Efficacy of biotic components in constructed wetlands for mitigating pesticides
    (Elsevier, 2023-03-17T00:00:00) Sachdeva, Saloni; Chowdari, Jabili; Patro, Ashmita; Mittal, Sunil; Sahoo, Prafulla Kumar
    Modern agricultural practices pose a significant danger to the aquatic ecosystem. Synthetic pesticides derived from agricultural activities are the most lethal and persistent substances that endanger the planet's ecology and human health; ineffective traditional waste-water treatment systems worsen the situation. On that account, these traditional technologies need to be upgraded and constructed wetlands have come to the fore as an environment and user-friendly technology. CWs consists of different type of biotic components, e.g., plants, microbes and abiotic components, e.g., gravels, sand, etc. which not only removes various types of organic pollutants but also help in their sustainable degradation into a simpler form. However, the factor circumscribing the effective implementation of constructed wetlands is the choice of aquatic macrophytes. The present chapter is an attempt to give a brief insight into using CWs for the treatment and removal of different types of pesticides present in wastewaters having different origins. Selected studies have been scrutinized for more than 60 aquatic macrophytes and 18 unconventional substrates that have shown promising results to mitigate pesticides from nonpoint water sources. Among various biological components, emergent macrophytes (P. australis, T. latiflolia, C. indica, and J. effuses) and associated microorganisms are the most suitable choice for constructed wetlands. Apart from pesticide reduction, macrophytes effectively stabilize the bed surface, reduces clogging, improve filtering, and promote microbial development. Following that, microorganisms can remove contaminants by accelerating chemical processes, biodegradation, and biosorption, as well as promoting plant development. Overall, the present chapter aims to highlight the importance of looking into the holistic interactions of macrophyte-microorganisms for a magnified outcome of removal efficacy. � 2023 Elsevier Inc.

    Engineered biochar for the effective sorption and remediation of emerging pollutants in the environment
    (Elsevier Ltd, 2023-02-27T00:00:00) Majumder, Sutripto; Sharma, Pooja; Singh, Surendra Pratap; Nadda, Ashok Kumar; Sahoo, Prafulla Kumar; Xia, Changlei; Sharma, Swati; Ganguly, Rajiv; Lam, Su Shiung; Kim, Ki Hyeon
    Various compounds that are emerging contaminants pose a significant risk to aquatic ecosystems and human health due to their potential to harm human health and the environment.Thus, there is an urgent requirement to use effective remediation methods and techniques to minimize the harmful impact of these contaminants on the environment. Biochar (BC) is a lightweight black residue that is made of carbon after the pyrolysis of biomass. BC is a product that is stable, rich in carbon, and exhibited improved properties. BC has come up with fascinating properties and results to remediate these pollutants from the soil effectively. Furthermore, it becomes possible to recover resources using BC because of the benefits such as (a) it offers in terms of cost, (b) the preservation of nutrients, and (c) the efficiency with which it absorbs pollutants. Consequently, it is necessary to have a knowledge of the interaction involving biochar and resource recovery to explore the applicability of BC in the cleaning up of the surroundings and the exploitation of wastewater. This review emphasize the physio-chemical and biological modification methods for the preparation of various types of engineered BC. Therefore, the present review aims: (i) provide an overview of emerging pollutants of human activities in soil (ii) synthesis and engineer BC for field application (iii) critically discuss and evaluate the factors affecting large-scale application techno-economic challenges. The review provided insight into the areas that need immediate attention in the upcoming investigation regarding the use of engineered biochar for wastewater treatment. � 2023 Elsevier Ltd
